It’s not the most advanced or accurate way to measure an engine’s compression ratio, but, hey, it worked. Removing 1.25 ...

Exhaust Port Heat But actual experiment shows that half of the cylinder head ... higher than that of gas expanded through the power stroke (giving its energy to the piston, which drives the ...

That is, the piston applies so much pressure and heat to the surrounding air that the fuel self-ignites when it enters the ...

The Piston Simulation function models the circular motion of a piston within a cylinder. It involves a chain of nonlinear functions. The response C is cycle time (the time it takes to complete one ...

A diesel engine's piston head looks like someone took a scoop ... Whereas, by comparison, the gas-powered Hemi option in the same Ram only has a 10.9:1 compression ratio. These engines require ...
