How Rotary Engines Work

How Rotary Engines Work

Introduction to How Rotary Engines Work

See more car engine pictures.

A rotary engine is an internal combustion engine, like the engine in your car, but it works in a completely different way than the conventional piston engine.
In a piston engine, the same volume of space (the cylinder) alternately does four different jobs -- intake, compression, combustion and exhaust. A rotary engine does these sam­e four jobs, but each one happens in its own part of the housing. It's kind of like having a dedicated cylinder for each of the four jobs, with the piston moving continually from one to the next.
The rotary engine (originally conceived and developed by Dr. Felix Wankel) is sometimes called a Wankel engine, or Wankel rotary engine.
In this article, we'll learn how a rotary engine works. Let's start with the basic principles at work.­

Principles of a Rotary Engine

The rotor and housing of a rotary engine from a Mazda RX-7: These parts replace the pistons, cylinders, valves, connecting rods and camshafts found in piston engines.

Like a piston engine, the rotary engine uses the pressure created when a combination of air and fuel is burned. In a piston engine, that pressure is contained in the cylinders and forces pistons to move back and forth. The connecting rods and crankshaft convert the reciprocating motion of the pistons into rotational motion that can be used to power a car.
In a rotary engine, the pressure of combustion is contained in a chamber formed by part of the housing and sealed in by one face of the triangular rotor, which is what the engine uses instead of pistons.
The rotor follows a path that looks like something you'd create with a Spirograph. This path keeps each of the three peaks of the rotor in contact with the housing, creating three separate volumes of gas. As the rotor moves around the chamber, each of the three volumes of gas alternately expands and contracts. It is this expansion and contraction that draws air and fuel into the engine, compresses it and makes useful power as the gases expand, and then expels the exhaust.
We'll be taking a look inside a rotary engine to check out the parts, but first let's take a look at a new model car with an all-new rotary engine.

­Mazda RX-8
­Mazda has been a pioneer in developing production cars that use rotary engines. The RX-7, which went on sale in 1978, was probably the most successful rotary-engine-powered car. But it was preceded by a series of rotary-engine cars, trucks and even buses, starting with the 1967 Cosmo Sport. The last year the RX-7 was sold in the United States was 1995, but the rotary engine is set to make a comeback in the near future.
The Mazda RX-8 , a new car from Mazda, has a new, award winning rotary engine called the RENESIS. Named International Engine of the Year 2003, this naturally aspirated two-rotor engine will produce about 250 horsepower. For more information, visit Mazda's RX-8 Web site.

The Parts of a Rotary Engine

­A rotary engine has an ignition system and a fuel-delivery system that are similar to the ones on piston engines. If you've never seen the inside of a rotary engine, be prepared for a surprise, because you won't recognize much.
Rotor
The rotor has three convex faces, each of which acts like a piston. Each face of the rotor has a pocket in it, which increases the displacement of the engine, allowing more space for air/fuel mixture.
At the apex of each face is a metal blade that forms a seal to the outside of the combustion chamber. There are also metal rings on each side of the rotor that seal to the sides of the combustion chamber.
The rotor has a set of internal gear teeth cut into the center of one side. These teeth mate with a gear that is fixed to the housing. This gear mating determines the path and direction the rotor takes through the housing.

Housing
The housing is roughly oval in shape (it's actually an epitrochoid -- check out this Java demonstration of how the shape is derived). The shape of the combustion chamber is designed so that the three tips of the rotor will always stay in contact with the wall of the chamber, forming three sealed volumes of gas.
Each part of the housing is dedicated to one part of the combustion process. The four sections are:

• Intake
• Compression
• Combustion
• Exhaust

The intake and exhaust ports are located in the housing. There are no valves in these ports. The exhaust port connects directly to the exhaust, and the intake port connects directly to the throttle.

STIRLING ENGINE TAKING ONE APART HOT AIR ENGINE Solar Powered Sun Generator Motor

The Stirling Engine (or hot air engine) Explained

1820, when steam engines operated everywhere, Robert Stirling, a Scottish vicar, and his brother James built a new engine. They used an outside burn, additionally hot air was sufficient for the operation of the engine. This principle has theoretically already been developed by the English flight pioneer Sir George Kayley twenty years earlier.

Stirling proceeds from the fundamental characteristic of air that it needs more space with rising temperature. If the volume remains constant, the pressure rises. All thermal engines work because of this characteristic. The basic principle of the Stirling engine is described in the following.
Mode of operation of the Stirling engine A machine, whose cylinder is alternating cooled and heated up again, would work, too. But for the change of temperature of the cylinder large energy quantities would be wasted. Stirling developed therefore a new principle: He uses two cylinders and two pistons: a working and a displace piston. The cylinder left is constantly heated up on the top while it is cooled at the lower part. The displace piston left seals not, it is of a porous structure, which lets air pass through. If the displace piston is now in the lower dead-center, air is strongly heated up and the pressure push on the working piston on the right, which slides to the right now. The left piston gets now pulled upward by the coupling of the two pistons. Air is strongly cooled, and together with compression work from the flywheel the working piston is brought again to the left, the displace piston slides down and the air is heated up again.
The re-generator
Robert Stirling called the displace piston also re-generator. In the upper animation only a sponge like piston is used, but in other constructions e.g. a close wire mesh is used as piston. This re-generator can, like the name already says, “regenerate” the air. If the piston goes upward, it is flowed through by warm air and takes up a part of the energy of the air then - it stores it. If the piston goes downward, it is flowed through by cold air now and delivers its stored energy to it. At the same time the wire mesh cools down. The piston helps so to avoid losses of energy. Also because of the re-generator, Stirling engines reach excellent efficiencies.
Modern Stirling engines The Stirling engine appeared at the beginning as a good alternative to the steam engines, but the success was not so big because of high production costs (two cylinders) and the small performances compared with its size. In this century, when people began to think about the environment, the stirling engine could play out its strengths partially.
It convinces by very quiet running, an excellent efficiency and good exhaust quality, since the burn takes place outside of the cylinder. The company Phillips for example designed 1938 a Stirling engine, which operated with helium as working gas (conductivity better than in air). The Phillips engine was quite well sold and could be operated with solar energy. So it was used as mobile refrigerator, for the power supply of smaller devices as well as on satellites.
The so-called ?-type stirling engine uses two pistons, which are around 90° out of phase in V-arrangement. The displace piston is missing, replaced by a fix installed re-generator. The ?-type Stirling engine functions because of the different lever lengths, with which the piston rods attack at the main shaft. For a closer explanation of this engine you can read the excellent description on the homepage of Peter Fete.
Future
Although the stirling engine would have a large development potential, there won’t be a larger production soon. The relatively small performance compared with the size and the weight of the engine hardly permit a use in cars or airplanes. But as small mobile generators, stirling engines are a good choice. It enjoys a big popularity in the model construction, where small steam engines and stirling engines experience a real revival.

Is There a Difference Between Two- and Four-Stroke Oil?

Thursday, July 29, 2010 @ 09:07 AM

BoatsOfFury

Two-stroke engines are more powerful and compact than the four-stroke, which is why they are found on the back of so many boats. But some boats do have four-stroke engines. When you purchase outboard motor oil, you’ll notice that there is both two- and four-stroke oil, but is there really any difference? As we all know, one of the biggest differences between the two types of motors is how you put oil in the system. In a two-stroke motor the gas and oil are mixed, while in a four-stroke the oil is contained in a separate compartment.

Two-stroke oil costs more, but is it really worth the extra money. The simple answer is yes. And the reason is that two-stroke motors are more susceptible to wear because of the immense amount of power they generate in half the movements. Two-stroke oils have higher ratings to ensure your engine gets the protection it need.

2- stroke engine

Engineering >> How Things Work >> How 2-Stroke Engines Work

Introduction

If you have read How Car Engines Work and How Diesel Engines Work, then you are familiar with the two types of engines found in nearly every car and truck on the road today. Both gasoline and diesel automotive engines are classified as four-stroke reciprocating internal-combustion engines. There is a third type of engine, known as a two-stroke engine, that is commonly found in lower-power applications. Some of the devices that might have a two-stroke engine include: Lawn and garden equipment (chain saws, leaf blowers, trimmers) Dirt bikes Mopeds Jet skis Small outboard motors Radio-controlled model planes In this article, you'll learn all about the two-stroke engine: how it works, why it might be used and what makes it different from regular car and diesel engines.

Two-stroke Basics

This is what a two-stroke engine looks like: You find two-stroke engines in such devices as chain saws and jet skis because two-stroke engines have three important advantages over four-stroke engines: Two-stroke engines do not have valves, which simplifies their construction and lowers their weight. Two-stroke engines fire once every revolution, while four-stroke engines fire once every other revolution. This gives two-stroke engines a significant power boost. Two-stroke engines can work in any orientation, which can be important in something like a chainsaw. A standard four-stroke engine may have problems with oil flow unless it is upright, and solving this problem can add complexity to the engine. Horsepower : For a complete explanation of what horsepower is and what it means to performance, check out How Horsepower Works. These advantages make two-stroke engines lighter, simpler and less expensive to manufacture. Two-stroke engines also have the potential to pack about twice the power into the same space because there are twice as many power strokes per revolution. The combination of light weight and twice the power gives two-stroke engines a great power-to-weight ratio compared to many four-stroke engine designs. You don't normally see two-stroke engines in cars, however. That's because two-stroke engines have a couple of significant disadvantages that will make more sense once we look at how it operates.

Car Engine Part by Part

Car Engine: Parts, Work, Problems. Part 1

Before to start working with the engine you should make sure that you have a proper manual. Online manual from ALLDATA is very good information material. The engine can be viewed as a heart of a vehicle which pumps air and fuel instead of blood. All engines are design to convert fuel and air into rotary motion in order to drive car’s wheels. How is this achieved?

Pistons. They move up and down in the cylinders. Most cars have four, six or eight pistons. The so called combustion chamber is placed in the upper side of the piston. Here the fuel and air are getting mixed before being ignited. Crankcase full of oil is situated on the other side of the piston. There are ring provided in pistons which prevent oil from getting into the combustion chamber and fuel and air from mixing with the oil. Pistons are made from lightweight aluminum and they are moving in the cylinders without touching their walls moving on a thin oil layer. In the event the rings are damage oil gets into the combustion chamber which results in grey smoke coming out of the exhaust. In this case the pistons can score the cylinder walls damaging the engine which leads to a serious repair.

Crankshaft. Through the connecting rod the crankshaft is connected to the pistons. As the piston is floating up and down in the cylinder it rotates the crankshaft thus converting straight line motion into rotary one.

Valvetrain. It consists of valves, arms, rocker, pushrods, lifters and cam shaft. The fuction f the valvetrain is similar to that of a traffic cop. It lets air and fuel in and out of the engine in a proper time. The camshaft being synchronized with the crankshaft by the chain or belt controls the timing.

These are the main parts of the engine and now you have an idea of their work. Now we are going to give you an idea of what is going on in the engine during its normal operation. Today most modern cars have four-stroke (four-cycle) engines. The cycle of their action consists of four distinct events. A complete cycle of four-stroke engine has two crankshaft revolutions. The 4-stroke cycle consists of the following events:

Intake stroke. The intake valve is opened by the camshaft and the piston is moving down the cylinder.

Compression stroke. The piston is moving back up the cylinder and makes the intake valve close. Thus the combustion chamber is sealed off. The fuel and air are getting mixed.

Power stroke. When the pistol is already near the cylinder top and the fuel is compressed this mixture is ignited with spark plug. The piston is pushed back down the cylinder by the explosion and the crankshaft is driven.

Exhaust stroke. When the piston is approaching the cylinder’s bottom, the exhaust valve opens and the gasses go out through the exhaust system.

So the four events mentioned above and taken together make a complete cycle. Are you sleeping now because you are tired of bare theory? We had to tell you all these boring things to give you a general idea of engine’s work. In the following part of the article we’ll talk about the real problems you can have with al the parts mentioned above.

Mazda Develops Improved Four Cylinder Engines

by Mazda in the News on October 14, 2009

Automakers are focusing on future powertrains for major reasons. First, consumers are demanding more fuel efficient engines. Secondly, new emissions regulations have placed pressure on automakers to reduce their fleet-wide fuel economy. While some automakers that have truck and SUV heavy lineup are a little more at risk, even Mazda is researching new ways to build fuel efficient gasoline and diesel engines.

Mazda’s goal is to reduce the fuel economy of its lineup globally by the year 2015 according to Alberta Mazda dealers. The earliest result of this push will be a new four cylinder engine that will be introduced in 2011. A redesigned version of the familiar 2.0-liter four cylinder engine and an all-new six-speed automatic transmission will help increase fuel mileage in city driving from 22 mpg to 32 mpg. A used Mazda dealer Calgary believes the strategy was to make such technology widely available, and not to limit it to just a few vehicles within Mazda’s global lineup. While no specific vehicle has been identified to receive this new engine, sources say it could be applied to numerous existing vehicles without significant modification.

Two vehicles that will likely receive new fuel efficient engines first are the Mazda MX-5 roadster and the Mazda5 MPV. Not only will these engines be available fleet wide by 2015, but Mazda Calgary suggests they will give consumers added fuel efficiency without the added costs usually associated with regenerative braking and hybrid powertrains.

Rotary engines, such as the one found on the Mazda RX-7, are also continually being developed by the automaker. The next generation rotary engine is said to have more than 30 percent improved fuel economy, while also featuring reduced weight over the existing engine.

How a Eaton G80 locker works

Auto Tech: Locking differentials

Eaton G80 locking differential. Click image to enlarge

By Jim Kerr; photos by Chris Chase



Drive axle, rear axle, differential: they are all terms we use when describing the unit that directs the engine’s power from the transmission to the tires. Differential may be the best term to use, because the drive wheels have to turn at different speeds when the vehicle goes around a corner. The differential allows this. It also splits the torque to the drive wheels, which is great when the tires are on good traction surfaces, but put one wheel on ice or loose dirt and you can easily become stuck. That’s where Eaton’s locking differential comes in useful.

Locking differentials lock both wheels together when additional traction is needed. This is usually done on rear axles only, because locking the front axle makes it very difficult to steer. Mercedes G500’s have offered an electric locking front axle, and combined with the locking rear axle, it is perfect for getting the vehicle over fallen logs and out of deep mud holes, but switch it off if you want to turn.

Dana and Eaton are two manufacturers of locking axles. Both have been around for decades. You can find Dana locking axles in a variety of larger trucks and delivery vans. They are designed for heavy-duty use and they have been used in everything from Canada Post delivery vans to one-ton Dodge trucks. Eaton has been making locking axles for both light duty and heavy-duty vehicles since 1973, and you only find them in GM vehicles.

Eaton recently demonstrated the advantages of a locking differential in a rear-wheel drive pickup over even the best four-wheel drive system and four wheel traction control. The vehicles were positioned with one wheel on dry pavement and the other rear wheel on a set of rollers to simulate a start with one wheel on ice. An object placed in front of one front wheel simulated driving up a curb or out of a rut. Then the driver attempted to drive each vehicle away.

Without a locking axle, the wheel on the rollers would spin but the vehicle wouldn’t move. Even with traction control, which brakes the spinning wheel to cause torque to transfer to the other side, there wasn’t enough traction to cause the vehicle to climb over the obstacle.

Next Generation Rotary Engine

Mazda Planning Direct Injection for Next Generation Rotary Engine

by George Delozier

Rotary engines are almost always associated with the name Mazda. For their small size, they can produce quite a bit of power, but at the expense of fuel economy and tailpipe emissions. Mazda, most likely in an effort to reduce the latter two, has been granted a patent for a newly designed rotary engine.

Among the minor changes to the famed rotary engine is the inclusion of direct injection and additional spacing between the pair of spark plugs. Although small, these changes could return some respectable gains in both the power and fuel economy department.

From the diagram, it also appears that the displacement will also be raised slightly above the previous 1.3 liters. Alongside the direct injection and more efficiently placed spark points, this new design could see a drastic drop in emissions as compared to the current examples.

The change in spacing would also allow Mazda engineers to alter the interior of the combustion chambers and improve airflow characteristics.

Mazda has yet to confirm or deny any plans for the future of their Renesis engine, but this would be a big step in the right direction if Mazda plans on continuing the rotary's legacy.
