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： An engine control apparatus which may be employed in automotive vehicles. The engine control apparatus is equipped with at least one of a combustion parameter or a controlled variable arithmetic expression. The combustion parameter arithmetic expression defines combustion conditions of the engine needed to achieve required values of engine output-related values such as exhaust emissions. The controlled variable arithmetic expression defines how to operate actuators for an operation of the engine to meet desired combustion conditions of the engine. The use of the combustion parameter or controlled variable arithmetic expression achieves simultaneous agreement of the engine output-related values with required values without mutual interference between combustion parameters associated with the combustion conditions. The engine control apparatus also works to correct target values of fuel injection-related combustion parameters based on a response delay of an air-related combustion parameter, thereby ensuring the accuracy in achieving required values of the engine output-related values.

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.

摘要： A fuel supply apparatus is provided which works to supply fuel such as a dimethly ether used as an alternative to a typical fuel for an internal combustion engine. The fuel supply apparatus includes a high-pressure pump working to feed the to injectors from a fuel tank through a common rail, a fuel return line, and a compressor working to add to a back pressure higher than a vapor pressure of the fuel to the return line. The addition of the back pressure higher than the vapor pressure of the fuel facilitates liquidizing of the fuel. This results in a decrease in leakage of the fuel, which improves the efficiency of burning of the fuel and ensures the startability and drivability of the engine.

摘要： A fuel injection control system for an internal combustion engine is provided which is designed to perform pilot injection of fuel into the engine through a fuel injector prior to main injection. The system monitors a combustion state parameter representing a combustion state of the fuel within a combustion chamber of the engine which has been sprayed in the event of the pilot injection. When the combustion state parameter is determined as lying out of a stable combustion range where the fuel is to burn stably, the system changes the number of pilot injections to be executed prior to the main injection and/or the quantity of the fuel to be sprayed in each pilot injection, thereby enhancing the ignitability of the fuel in the pilot injection.
