Automotive giant General Motors has filed patents for a two-stroke engine of the type whose excess emissions took it off the road decades ago as a technology seen as having no future.The patent is for ...

Effects of engine parameters on performance can be investigated by using a mathematical model of the engine cycle, and the computed results may be used to optimize performance. The following design ...

Diesel is dead? Not quite yet. Achates announced Friday that it has produced a heavy-duty, two-stroke diesel engine with near-zero emissions that costs less than a conventional engine and is expected ...

Two common myths of emission control, according to John Sartain, a Miratech Crop. engineering manager, are that catalytic converters don’t work on two-stroke engines because such engines run “dirty,” ...

Intake, compression, power, then exhaust. Every 4-stroke engine ever made – about 80% of all engines currently in existence – function on this principle – even rotary engines. But now, Porsche has ...

Internal combustion engines are literally the engines of the modern world. Without the invention of these genius mechanical creations, our world would be markedly different and the pace of life would ...
