The piston moves up and compresses the trapped air fuel mixture that was brought in by the intake stroke. The amount that the mixture is compressed is determined by the compression ratio of the engine. The comp
The piston starts at the top, the intake valve opens, and the piston moves down to let the engine take in a cylinder full of air and gasoline. This is theintake stroke. Only the tiniest drop of gasoline needs to be mixed into the air for this to work. (Part 1 of the animation) T...
As the gas expands, it pushes the work piston to the right, which drives the flywheel and whatever the engine is powering. In this part of the cycle, the engine converts heat energy into mechanical energy (and does work). Transfer and cooling: The displacer piston moves to the left and...
The radial engine has the same sort of pistons, valves and spark plugs that any four-stroke engine has. The big difference is in the crankshaft. Instead of the long shaft that's used in a multi-cylinder car engine, there is a single hub -- all of the piston's connecting rods connect...

The four-stroke cycle in a gasoline/petrol engine: The four-stroke cycle is the process by which an internal combustion engine converts fuel into mechanical energy. Here's a breakdown of each stroke - 1. Intake stroke During the intake stroke, the intake valves open, and the piston moves ...
Before we take a look inside a speedometer, it will be helpful to review how a car works in the first place. The basic process is described below: Piston engines use energy from a burning fuel-air mixture to move a piston up and down in a cylinder. This reciprocating motion of the pi...
Engine intake and exhaust valves: These are the stopping points that limit and allow for the influx of fuel and the expulsion of exhaust. Combustion chamber: This part of the engine contains the tiny explosions that create the power needed to propel a vehicle forward. Piston: This mechanical ...
In a flathead engine, the valves are in the block, rather than in the head, and they open in a chamber beside the piston. The head in a flathead engine is extremely simple -- it is a solid metal casting with a hole drilled in it to accept the spark plug. The camshaft in the ...
