The technically Gas4stroke pdf term is actually four stroke cycle. The four stroke engine is probably the most common engine type nowadays. It powers almost all cars and trucks. The four strokes of the cycle are intake, compression, power, and exhaust.

Each corresponds to one full stroke of the piston; therefore, the complete cycle requires two revolutions of the crankshaft to complete. The illustrated engine features a poppet intake valve which is drawn open by the vacuum produced by the intake stroke.

The exhaust valve is held shut by a spring not illustrated here.

Compression As the piston rises, the poppet valve is forced shut by the increased cylinder pressure. Power At the top of the compression stroke, the spark plug fires, igniting the compressed fuel. As the fuel burns it expands, driving the piston downward.

The upward stroke of the piston drives the exhausted fuel out of the cylinder. Ignition System This animation also illustrates a simple ignition system using breaker points, coil, condenser, and battery. A number of visitors have written to point out a problem with the breaker points in my illustration.

In this style ignition circuit, the spark plug will fire just as the breaker points open. The illustration appears to have this backwards. My original intent was to accurately show that the points need to remain closed for only a fraction of a second, called the dwell.

By illustrating this, I inadvertently obscured the overall operation of the circuit. Larger four stroke engines usually include more than one cylinder, have various arrangements for the camshaft dual, overhead, etc. None of these enhancements changes the basic operation of the engine.VTI - Vocational Training Institute, Vacoas, Mauritius offers a variety of MQA Approved Courses.
