Title:
CONTROL APPARATUS FOR INTERNAL COMBUSTION ENGINE AND CONTROL METHOD OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2013/076564
Kind Code:
A3
Abstract:
A control apparatus that controls a fuel supply system of an internal combustion engine of a vehicle, the fuel supply system including a low-pressure fuel supply mechanism that injects low-pressure fuel into an intake port of the internal combustion engine, and a high-pressure fuel supply mechanism that injects high-pressure fuel into a cylinder of the internal combustion engine, includes a control portion that controls a supply of fuel to the internal combustion engine from the fuel supply system. Immediately after the vehicle stops, when the internal combustion engine satisfies a predetermined condition, the controller idles the internal combustion engine by supplying the high-pressure fuel to the internal combustion engine by the high-pressure fuel supply mechanism, and after stopping the supply of fuel by the high-pressure fuel supply mechanism, idles the internal combustion engine by supplying the low-pressure fuel to the internal combustion engine by the low-pressure fuel supply mechanism.
