Operation and Performance of Reciprocating Engine

The continuing rotation of the crankshaft drives the piston back up, ready for the next cycle. The piston moves in a reciprocating motion, which is converted into circular motion of the crankshaft, which ultimately propels the car. Gas engines usually have about the same about of horsepower as they do torque. The diesel engine usually has twice as much torque as it does horsepower, thus it is the better hill climber and load carrier.

The power system consists of a four-stroke engine, a carburettor to transform incoming fuel into steam, a obstruct to control the air-fuel ratio, transmission, and drum brakes. A cylindrical piston, made of aluminium alloy as most people

In the first stroke, the piston moves from top to bottom (BDC) and air is drawn through

WORKING OF REPULSINE ENGINE The working of Repulsine engine can be explained by the combination of the

Contain 4 main components, Compressor housing, compressor wheel, Turbine housing, along with a turbine wheel. Exhaust gas enters the system through the compressor housing while the air flows over the compressor wheel it causes a chain reaction which results in a counterclockwise rotation of the turbine wheel. This rotation is the stage when exhaust gas turns to air pressure. The air pressure is returned to the engine through a waste-gated return hose/line. The pressurized air is then interchanged with combustible diesel fuel and ignited. The bigger the turbo charger is allows more mass air flow which results in more fuel being burned all this combined equals a greater amount of horsepower

Tires squealing, superchargers whining, turbos screaming as the air is forced to mix with fuel. A concoction resulting in immense, intense power from what some would call a box of metal. A meaningless, mass produced, grocery getter. However, these stereotypes are not true, due to one attribute. When that pedal touches the floor, magic is in progress, and pure, raw, unkempt power is unleashed. Air and fuel forced to mix, as if they were great enemies fighting one another. The spark plugs, igniting the furious battle between them, causes an earth shaking explosion. The pistons scream as the energy forces them to slam downwards, turning the ever-mighty crankshaft. The energy rushes through the flywheel, turning the many transmission gears, funneling angry horsepower through the drive shaft. The rear axle is the surrogate through which the tires squeal, launching the car down a ¼ mile track in under 10 seconds.

Over the years, there have been many different configurations of radial engines, from three-cylinders to nine cylinders, with the seven and nine cylinder versions preferred. When more power is required, a second engine is bolted at an angle to allow cooling air to reach the second set of cylinders. The famous P & W “corn-cob” engine had four banks of seven-cylinder engines attached to one crankshaft. That’s 28 cylinders, and 56 spark plugs to regularly change.

The Vought F4U Corsair first flew May 1940. It was created by Chance Vought, the Corsair was an American aircraft. This aircraft was created to be a fighter airplane, it attracted eyes from all over. The corsair was introduced in World War II it was the most feared airplane in the sky’s. Its known by the Japanese as the Whistling death. As Americans battled across the pacific closing in on Japan. The corsair earned a fearsome name, not only as a fighter but also a bomber. At sea the Corsair shot down 100s of kamikaze fighter planes.

It houses four valve combustion chambers with a direct fuel injection system. Its compression ratio is 11.2:1 that has an efficient boasting power as it runs on regular gasoline. The afore mentioned power and torques of the engine are considerably high, performing an exertion up to 6000 rpm.

The piston then travels down pulling in fresh air, (third stroke), after the piston bottoms again it travels up compressing the fresh air, (fourth stroke). The fuel is then injected and one cycle is completed in 720 degrees or two full rotations of the crankshaft.

A very common variant of the internal combustion engine is the four stroke engine. These engines have four "strokes" for each combustion cycle. These engines are

Since Stirling engines have been around for over 200 years the ways of making them and improving the efficiency has taken many turns. In the early stages of the engine the ability to create highly efficient engines became limited due to technology and materials available. All the sources that I sampled agreed on what a Stirling engine was and what characteristics made them different. A Stirling engine is a heat engine that has the heating and cooling of gas that presses on the pistons moving both the gases and the pistons creating energy (American Stirling Company, n.d). Other articles on Stirling engines agree saying that Stirling engines are a machine that operates in a closed regenerative thermodynamic cycle. The use of Stirling engines is based off the Stirling engine cycle of power (Asnaghi, Ladjevardi, Izadkhast, Kashani, 2012). And then later heat activated cycle engine. Many large companies attempted to use Stirling engines for its advantages (Schimmoller, 2001). Again, another respected article states that the Stirling engine is based on the materials, development, and design of the engine to determine how well it works (Tarawneh, Al-Ghathian, Nawafleh, Al-Kloub, 2010). Then explaining how the Stirling engine works applying an external heat source to a closed cylinder where the cyclical expansion and compression of air inside the cylinder drives the pistons up and down (Helman, 2015) and because the engine is a closed system the expansion

Start up on the ignition and the engine seems responsive from the word go but with its three cylinder capacity, it comes into its own when the turbo has spooled up and that happens after 1900 rpm. Beyond this, you get enough pulling power. While there is no sudden increase in power delivery and the engine does not rev quickly but you still get it in a linear way and there is constant build up of power that makes driving in the city convenient.

There are other components in the I.C. Engine like Bearings, Flywheel, spark plug, fuel pump and carburetor but majority of the parts contributing in the mechanism are explained above.

For automotive Engines there are three main areas of steady state operation requiring different air fuel ratios.
