Summary: | The invention provides a gasoline injection amount control method for a dual-fuel engine. The method includes the following steps that the maximum permission gasoline injection amount and the minimum permission gasoline injection amount after correction are acquired based on the current operating state of the engine according to the circulation gas inlet amount, the engine revolution speed, the temperature inside a cylinder and the EGR rate; if the current gasoline injection amount is larger than the maximum permission gasoline injection amount, the maximum permission gasoline injection amount is used for executing gasoline injection; if the current gasoline injection amount is smaller than the minimum permission gasoline injection amount, the minimum permission gasoline injection amount is used for executing gasoline injection; otherwise, the current gasoline injection amount is used for executing gasoline injection. Meanwhile, the invention further relates to a gasoline injection amount control system for the dual-fuel engine. According to the technical scheme, the gasoline injection amount can meet the using requirement, gasoline can be burnt sufficiently, and THC emission is lowered; meanwhile, the phenomenon that the noise of the engine is too large is avoided, and the advantages of the dual-fuel engine can be performed to a greater extent. |
