A method for determining the injection law of a fuel injector (4) to be tested; the method includes the steps of: interrupting the feeding of fuel from the fuel pump (6) to the common rail (5); avoiding the opening of all the fuel injectors (4) except for ...

A fuel injection apparatus for diesel engines is provided which is designed to diagnose a failure in injecting fuel into each cylinder of a diesel engine by monitoring a diagnostic signal appearing on a single diagnostic signal line. The apparatus includes...

A system and method to control engine valve timing so that an internal combustion engine may be quickly started. Electromechanical valves are controlled to allow an engine to start with reduced cranking time. The method controls intake and exhaust valves w...

A method in an internal combustion engine is presented. Controllable valves and controllable air and fuel input means are provided at each cylinder. The method includes controlling the valves and the air and fuel input means so that a transition is made fr...

An initial number of fuel injectors is operated in a first mode during an engine cycle in which one fuel shot per injector per engine cycle is realized. A second set of injectors is then operated in a second mode during the same engine cycle using a corres...

The injectors (131) are associated with a fuel injection unit (10) such that the selected number of injectors (131) have the most similar characteristic curve possible, over at least a given section of the injection quantity/control duration curve (EM(T))....

The startup time of an engine (2) is shortened by performing initial fuel injection after the start of cranking on a cylinder (#1-#4) undergoing an intake stroke and a cylinder (#1-#4) undergoing an exhaust stroke. After the initial fuel injection, HC emis...

A fuel injection control device for an internal combustion engine (2) is provided with a controller (1) functions to command the fuel injectors (8) for a cylinder in the exhaust stroke and for a cylinder in the intake stroke to simultaneously perform a pri...

The invention relates to a control apparatus (115) of a cylinder injection of fuel type internal combustion engine (107) executing a dilute combustion, which can satisfy a requirement of rapidly changing an engine torque while restricting a deterioration o...
