Compression is an integral ingredient in the operation of your vehicle’s internal combustion engine. Your engine works on a four-stroke cycle: intake, compression, expansion/power, and exhaust.

During the engine's cycle, the initial fuel-air mixture is too lean for spark ignition. However, near the top of the compression stroke, additional fuel is injected near the spark as quasi ...

As an example, let’s start with a 6.0L LS engine with a 4.00-inch bore, a 3.62-inch stroke, a 70cc combustion chamber, a pure ...

At bottom-dead-center (BDC) the inlet valve is closed and the compression stroke (b) starts. Work is done on the air ... page represents this behavior for a Mitsubishi direct injection engine ...

Diesel engines produce more torque by incorporating a longer stroke (meaning the piston moves farther), higher compression, and turbocharging technology. Unlike a four-stroke engine, which ...

Porsche has filed patents for an engine cycle with two combustion ... The conventional four-stroke cycle has phases comprising induction, compression, expansion, and exhaust (with combustion ...

The system behind Porsche’s six-stroke engine is complex, but the basic idea is that the crankshaft operates through two ...

A RARE Victorian engine, one of only three on earth, has been found by accident in an Edinburgh attic. The magnitude of the ...
