Flammability of mixture containing syngas and gasoline in spark ignition engine is discussed as a part of feasibility study of new proposed gasoline engine system, which consists of two engines. In the engine system, the syngas is partial burnt gasoline, and the reactor is one of the spark ignition engines. The syngas is supplied to another engine. The ratio of syngas against mixture was about 34 %. Therefore it was thought that the syngas was burnt in another engine. Lower heating value of the mixture containing syngas, gasoline and air is quite low, comparing with same volume of stoichiometric mixture not containing syngas. The system was proposed to improve thermal efficiency of partial load condition. Experimental data shows the possibility that the system reduces throttle loss. In addition, process of gasoline gasification in spark ignition engine is also effective to improve thermal efficiency.
