The Hythane fuel mixed hydrogen to methane has being investigated to use as substitute fuel of gasoline. When gaseous fuel of this kind is used for a direct injection two-stroke engine, it is difficult that the in-cylinder eqivalent ratio is correctly cleared. Since it is difficult that we can get to know easy quantity of the in-cylinder fresh air charge on the two-stroke engine and of fuel injected at high pressure fuel injection. Therefore we investigated a method to clear the in-cylinder eqivalent ratio from trapping efficiency and diagram of exhaust gas concentration on the two-stroke engine. As a result of investigation, it has be cleared that the in-cylinder eqivalent ratio in case of gaseous fuel direct injection on the two-stroke engine is obtained within about five percent.
