摘要： A fuel injection control device controls an operation of an injector such that fuel to be injected into a combustion chamber per combustion cycle is divided and injected at least through a first injection and a second injection, which is performed with a larger fuel quantity than the first injection after the first injection. The fuel injection control device includes an acquiring section and a first combustion state estimating section. The acquiring section acquires a sensing value of cylinder pressure in the combustion chamber sensed with a cylinder pressure sensor. The first combustion state estimating section estimates an actual combustion state of the fuel injected by the first injection based upon a second combustion timing cylinder pressure sensing value attributable to combustion of the fuel injected by the second injection out of the cylinder pressure sensing values.

摘要： A compression ignition engine injects fuel through injection holes of an injector at a substantially constant injection rate to atomize the fuel so that the fuel can be easily vaporized and to make the fuel penetrate an atmosphere inside a cylinder. A spatial distribution of the injected fuel in which mixing of the fuel and air is promoted as the fuel recedes from the injection hole and the fuel reaches a premixing space where the fuel is premixed with the air is provided. The engine controls oxygen concentration inside the cylinder and an ignition delay so that a ratio of a quantity of the fuel injected before a start of ignition to a total fuel injection quantity falls within a range from 25% to 50% and so that the premixed gas formed in the premixing space is combusted serially.
