  • Publication number: 20160169148
    Abstract: An engine (10) is a cylinder injection engine, and includes an injector (21) that directly injects a fuel into a combustion chamber (23), and an ignition plug (34) that generates an ignition spark in the combustion chamber (23). An ECU (40) performs multiple first injections to each produce an air-fuel mixture of a lean air-fuel ratio in the combustion chamber (23) before an ignition in one combustion cycle of the engine, and performs a second injection to produce an air-fuel mixture of a rich air-fuel ratio in the combustion chamber (23) before the ignition and after the first injection. In particular, the ECU implements the multiple first injections in such a manner that the first injection implemented early among the multiple first injections produces an air-fuel mixture leaner than that of the first injection implemented subsequently. The ECU implements the second injection only once immediately before an ignition timing.

  • Publication number: 20160169176
    Abstract: A decoupling element, for decoupling a fuel injection valve from a cylinder head, includes a body that, in the mounted state, surrounds a housing of the fuel injection valve. The body is fashioned to include a cylinder-side support region to be supported on the cylinder head, and a valve-side support region for supporting the fuel injection valve. When the fuel injection valve is supported at the valve-side support region, the body is loaded with pressure. Only the cylinder-side support region of the body is fashioned in the shape of a closed ring, which connects segments of the body distributed around a circumference. The decoupling element enables the reduction of the transmission of noise from the fuel injection valve to the cylinder head.

  • Publication number: 20160169179
    Abstract: [Solving Means] In a nozzle plate of the present invention, part of fuel flowing out from the fuel injection port of the fuel injection device is atomized by colliding with an interference body, is rapidly bent in a flowing direction, and collides with the fuel that is flowing straight through nozzle holes and an orifice to make the fuel flow that flows straight through the nozzle hole and orifice turbulent. The orifice includes a corner portion formed by an outer edge portion of the interference body and having a sharply pointed shape without roundness at a part of an opening edge. The corner portion makes an end portion of a liquid film of fuel passing through the orifice into a sharply pointed shape for ease of atomization by friction with air.

  • Publication number: 20160169187
    Abstract: An induction cleaning analyzing system includes a pressure sensor, an ignition event detector, and a control module. The pressure sensor measures airflow pressures of intake air and/or exhaust from cylinders in a common airflow pathway of a vehicle. The ignition event detector determines ignition events of the cylinders. The control module obtains pressure waveforms representative of the airflow pressures and divides the pressure waveforms into waveform segments. The control module associates different subsets of the waveform segments with different ones of the cylinders using the ignition events. The control module also identifies cyclic variations in the airflow pressures flowing in the common airflow pathway and caused by at least one of the cylinders by examining the waveform segments associated with the at least one of the cylinders.
