Title:

GAS FUEL FEED ENGINE

Document Type and Number:

Japanese Patent JPH06221193

Kind Code:

A

Abstract:

PURPOSE: To improve the fuel consumption and embody engine performance while exhaust gas from a gas fuel feed engine is purified.

CONSTITUTION: The temperature state of an ignition plug is estimated through detection of the load state of an engine by means of a number of revolutions of engine sensor 45 and an accelerator opening sensor 46 or an ignition plug temperature is detected by means of a plug temperature sensor 47. As a result, when it is confirmed that the plug temperature is low, it is decided by a fuel ratio deciding means 52 in an ECU 50 serving as a control means that a feed ratio of gas fuel is increased. Meanwhile, when the plug temperature is in a high state, it is decided by the fuel ratio deciding means 52 that a feed ratio of liquid fuel is increased. Flow rate regulating valves 24 and 28 are controlled by a fuel feed control means 53 according to the decided feed ratio to regulate gas fuel, and liquid fuel is regulated by controlling a fuel pump 42 and an injector 36.
