Abstract

Bench tests of a 492Q gasoline engine using LPG were carried out and the results are presented.The relations between NO x emissions and air fuel ratio,load,ignition timing of the LPG engine at medium and high speed are discussed and compared with gasoline engine.The bench tests show that the NO x emission of the engine using LPG is higher than those of the engine using gasoline,and some technique must be introduced to reduce the NO x emissions.
