20080302334 | Multi-Cylinder Engine Fuel Control Method, Engine Fuel Injection Amount Control Method and Engine Operation State Discrimination Method Using the Same, Propulsion Apparatus for Multiple Engines, and Fuel Injection Control Method During Crash Astern in Marine Engine With Reduction and Reversal Device - Rotation recognition means for recognizing a revolution of a crankshaft based on the cylinders before the combustion cycle of a cylinder in question is provided. When the supply of fuel by injection from an injector to a certain cylinder of the six cylinders has become impossible, then control is performed to change the number of cylinders targeted by the rotation recognition means so as to recognize the revolution of the crankshaft for all six cylinders whose combustion cycles are consecutive prior to the combustion cycle of the cylinder in question, and to stop the supply of fuel from the injectors for supplying fuel to cylinders whose combustion cycles are equally spaced from the cylinder to which the supply of fuel is not possible, so that the spacing between the combustion cycles in the cylinders whose combustion cycles come before and after and sandwich the cylinder to which the supply of fuel is not possible becomes uniform. | 12-11-2008 |
20090277420 | Accumulator-type fuel injection apparatus and internal combustion engine provided with that accumulator-type fuel injection apparatus - In one embodiment, the high-pressure pump ( | 11-12-2009 |
20100198483 | Engine - In an engine which may show a behavior where an engine speed is not always minimized after compression top dead center of a cylinder in which poor fuel injection occurred, the cylinder in which poor fuel injection occurred is detected. A common rail diesel engine ( | 08-05-2010 |
20100198484 | Engine - The purpose of the present invention is to provide an engine having a revision means which regulates rotation speed of each of cylinders while reflecting specific unevenness of rotation of each of the cylinders. With regard to an engine | 08-05-2010 |
