Find out what triggers detonation and pre-ignition, why ignition timing really matters, and how these problems can seriously ...

A thermodynamic analysis based on a pressure-time history measured during the combustion in a SI engine is a commonly used tool used for analyzing the combustion process. Both one-zone and two-zone ...

Detonation is a dirty word around hot rods. Nobody likes to talk about it because when it happens, it usually means some lapse of attention during engine or vehicle assembly has occurred. By the time ...

Dilute operation of a SI engine offers attractive performance incentives. Lowered combustion temperatures and changes in the mixture composition inhibit NOx formation and increase the effective value ...

WEST LAFAYETTE, Ind. – Researchers at Purdue University have developed new combustion technology that can shrink the size of engines and eliminates the need for them to be round in shape. The novel ...

THE arrival in Great Britain from the United States of ethyl petrol—the anti-knock fuel containing 6 c.c. of ethyl fluid (lead-tetra-ethyl 54-5 per cent.; ethylene dibromide 36-5 per cent.; and ...
