Abstract
GHP which, is the heat pump system for an air conditioning, is directly driven the compressor by a small gas engine. The NOx was reduced 70% less than a conventional gas engine with improvement of thermal efficiency. The combustion chamber shape using strong squish flow is improved in order that the pattern of a heat release is changed to be suitable.
Because the relation between NOx and the thermal efficiency is the trade off relation, the air fuel ratio and the ignition timing must be precisely controlled. Detecting the change of the Pi variation calculated from the engine speed variation can control the air fuel ratio.
