Fuel injection control apparatus of two-stroke engine

A fuel injection control apparatus of a twostroke engine comprising:

• an air pump driven by the engine;
• an air blast valve provided with a nozzle opening connected to said air pump through a compressed air passage, a fuel injector for injecting fuel into said compressed air passage, and an opening and closing valve for controlling the opening and closing of the nozzle opening;
• judgement means for judging if the compressed air pressure in said compressed air passage is more than a predetermined set pressure;
• and
• control means for controlling said fuel injector and said opening and closing valve to inject fuel from said fuel injector during the opening of the opening and closing valve and cause the injected fuel to be ejected from said nozzle opening by inertia force when the said compressed air pressure is less than said set pressure and to inject fuel from said fuel injector during the closing of the opening and closing valve and cause the injected fuel to be ejected from said nozzle opening by compressed air during the opening of the opening and closing valve when the compressed air pressure is higher than said set pressure.
