An engine throttle control device
Document Type and Number:
Japanese Patent JP6260795
Kind Code:
B2
Abstract:
A fuel control system of an engine is provided which controls, by using a tumble flow, a behavior of fuel directly injected into a combustion chamber formed inside a cylinder of the engine. The fuel control system includes a fuel injector for directly injecting the fuel into the combustion chamber, a tumble flow generator for generating the tumble flow within the combustion chamber, and a fuel injector controlling module for causing the fuel injector to inject the fuel at a first injection timing and then inject a smaller amount of fuel than an amount injected at the first injection timing, in a direction opposing a positive direction of the tumble flow at a second injection timing, the first injection timing designed to be in an intake stroke of the cylinder, the second injection timing designed to be in a latter half of the compression stroke of the cylinder.
