摘要： In a fuel injection nozzle including multiple nozzle hole groups each having multiple solitary nozzle holes, a group distance C between two of the nozzle hole groups is 0.8 or more times larger than an in-group hole distance α in a nozzle hole group. The group distance C is the minimum interval of inter-group intervals that are formed between (i) peripheral boundaries of solitary nozzle holes belonging to a first nozzle hole group and (ii) peripheral boundaries of solitary nozzle holes belonging to a second nozzle hole group adjacent to the first nozzle hole group. The in-group hole distance α is the minimum of intervals between peripheral boundaries belonging to each nozzle hole group.

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.

摘要： A fuel distillation property determining apparatus for use in a multi-injection system for diesel engines. The apparatus acquires a physical quantity indicating a state of burning of fuel in the diesel engine, determines a physical quantity variation sensitivity defined by a ratio of a quantity variation that is a difference between a first value of the physical quantity, as acquired upon execution of a first one of a sequence of sub-injections, and a second value of the physical quantity, as acquired upon execution of a following one of the sub-injections, to a difference between a first quantity of fuel sprayed in the first sub-injection and a second quantity of fuel sprayed in the following sub-injection, and determine a cetane value of the fuel based on a predefined relation between the physical quantity variation sensitivity and the cetane value. This ensures the accuracy in determining the cetane value at low costs.

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.
