Document Type and Number:
Japanese Patent JP5243312
Kind Code:
B2
Abstract:
In an in-cylinder injection type multicylinder internal combustion engine for uneven interval firing, including a plurality of air-fuel mixture injection valves for directly injecting an air-fuel mixture into a combustion chamber of each cylinder, the air-fuel mixture injection valves being mounted on a multicylinder engine body and each having a fuel injection valve and an air injection valve, and an air pump actuatable by power transmitted from a crankshaft for discharging compressed air. The air pump is connected in common to the air-fuel mixture injection valves with the injection pressure of the air-fuel mixture injection valves in each cylinder being prevented from changing for good combustibility. The discharge timing of the air pump is set out of synchronism with the injection timings of the fuel injection valves and the air injection valves of all the cylinders.
