www.epicphysics.com A 3d engine animation showing how a four stroke engine works. Also shows the four individual strokes involved - induction, compression, power and exhaust, more easily remembered as suck squeeze bang and blow. The four stroke engine is undoubtedly the one we use most during our everyday lives. It is used in most automobiles as it has high efficiency and high power. The diesel engine is used for more robust tasks such as transporting goods and people as it has more pulling power and higher torque. As the name implies it works on four cycles -- induction, compression, power and exhaust. The induction cycle is where the fuel and air mixture is sucked into the cylinders by the motion of the piston. The mechanics of the engine has opened the inlet port at the top of the cylinder, this allows the fuel air mixture in, the port has been opened by the camshaft. The piston is an airtight seal inside the cylinder, so when it moves downwards it creates a partial vacuum inside the cylinder which sucks the fuel and air mixture in. The fuel/air mixture is usually at a ratio of between 15:1 or 18:1, ie. 15 parts of air to one part of fuel for a typical 4 stroke gasoline engine. During all four cycles there is a complex movement of all of the components of the engine, these are best explained by the video below so i will not get into them here as they are easier to understand when seen. The compression cycle is when the piston is on its way back up inside the cylinder ...
