Abstract

See full text

A fuel injection system that can maintain a high accuracy level in adjusting the quantity of fuel injection in a system in which the first injector injects fuel in the liquid phase and the second injector injects fuel in the gaseous phase. The quantity of fuel injection of each injector is adjusted respectively in accordance with the fuel quantity required each time. The temperature of the first injector is estimated based on the temperature of the engine's cooling water and the temperature of the fuel in the fuel passage from the fuel tank to the first injector, and the quantity of vapor generated in the fuel passage is determined according to the estimated temperature and the fuel pressure in the fuel passage. The quantity of fuel injection of each injector is adjusted according to the determined quantity of vapor generated.
