Low- And High-Compression Fuel Economy Engines: The Techniques Are About The Same, But The Approach To Each Is Somewhat Different. A.Most stock cylinder heads have factory-cut undercuts of the type ...

Compression: An automotive term used by everybody, forever. Let's get into some detail and maybe develop a better understanding. Pressure, and more pressure: It's a must-have to produce power within ...

The declining quality of gas requires enthusiasts to reduce their engine's compression ratio accordingly, but since high-performance, low-compression forged pistons may not be available for all ...

Any diesel-engine manufacturer that confidently claims it produces an oil-burner with the “world’s lowest compression ratio,” will no doubt draw the immediate attention of inquisitive enthusiasts, ...

October 3, 2005 It has been a sudden realisation - the world is running out of oil and the laws of supply and demand are set to make petrol prohibitively expensive in the very near future. Sonex ...

SAE Transactions, Vol. 110, Section 3: JOURNAL OF ENGINES (2001), pp. 1234-1252 (19 pages) Using methanol as a fuel, this study examines the chemical-kinetics mechanism responsible for the enhancement ...

In a conventional piston engine, the compression ratio defines the relationship between the largest and smallest volume of a cylinder - when its piston is at bottom dead centre and top dead centre ...
