he takes a failed engine design and musters up the oomph to get it running. The whole build began with an idea for a different kind of intake and exhaust valve. [Meanwhile In the Garage] dreamed ...

In a 4-stroke engine, the cycle begins with the intake stroke. As the piston travels downward, the camshaft moves to the position that opens the intake valve. The vacuum from the downward motion ...

At the very end of the exhaust stroke ... engine rotation is stopped at valve overlap at the rocker arms on just the #1 cylinder (very front), the #2 exhaust valve, #3 intake valve, #4 exhaust ...

With four-stroke ... the intake valve, contaminating the incoming air/fuel charge with exhaust gasses. Signs of that reversion are seen when removing the intake valves from an engine and seeing ...

To reinforce this point, consider the intake stroke of an engine. The intake valve is open ... exhaust valves to open earlier or later in a 4-stroke cycle. The aim was to improve volumetric ...

The key distinction between a conventional 4-stroke engine and a 6-stroke design lies in the cam and valve timing ...

In keeping with their continual advancement with the years, Weslake is now about to release a new pushrod-operated, four-valve cylinder-head conversion for the small-block Chevrolet engine.

Heavy repairs are also much easier on an inline-6 engine. For instance, the exhaust and intake ... longer stroke. For example, Mercedes' 3.0-liter M256 motor has an 83-mm bore and 92.4-mm stroke ...

If, as has so often been said, an engine is nothing other ... port does flow more up at the higher valve lift numbers. Part of this is due to a bigger intake valve, but about 70 percent of the ...

A conventional car engine takes four piston movements, or strokes, to go through intake, compression, combustion, and exhaust. In a two-stroke cycle ... cylinder head or valve-train components ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% ... engine and the 6-stroke design is in the cam and valve timing. Porsche's design is vastly different ...
