Abstract
In a fuel supply control apparatus for an internal-combustion engine, liquid fuel is vaporized and is supplied to a fuel gas passage leading to an intake air passage. The flow rate of the vaporized fuel flowing through the fuel gas passage is detected, and the flow rate of the fuel is calculated in accordance with the load of the engine. As a result, feedback control of the fuel to be supplied to the engine is carried out so that the detected flow rate of the vaporized fuel is close to the calculated flow rate of the fuel.
Claims6
A fuel supply control apparatus for an internal-combustion engine having a fuel gas passage leading to an intake air passage, comprising:
- a means for vaporizing liquid fuel and supplying vaporized fuel to said fuel gas passage;
- a means for detecting the actual mass flow rate of said vaporized fuel flowing through said fuel gas passage said actual mass flow rate detecting means being provided in said fuel gas passage downstream of said liquid fuel vaporizing means;
- a means for detecting the load of said engine;
- a means for calculating the mass flow rate of fuel in accordance with the detected load of said engine;
- and
- a means for controlling feedback of fuel to be supplied to said engine so that the detected actual mass flow rate of said vaporized fuel is close to the calculated mass flow rate of fuel.
