Title:
Engine control
Document Type and Number:
Japanese Patent JP6323683
Kind Code:
B2
Abstract:
A control system of an engine is provided, which controls, by using a tumble flow, a behavior of fuel that is directly injected into a combustion chamber formed inside a cylinder of the engine. The 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, an ignition timing control module for controlling an ignition plug to ignite after a top dead center on compression stroke of the cylinder in a cold state of the engine, and a fuel injector control module for controlling the fuel injector to inject the fuel at an intake-stroke injection timing, a compression-stroke-early-half injection timing, and a compression-stroke-latter-half injection timing. The fuel injector control module controls the fuel injector to inject the fuel toward a vortex center of the tumble flow at the compression-stroke-early-half injection timing.
