Abstract: An ignition control apparatus according to one embodiment of the present invention is an ignition control apparatus which generates, in an ignition coil, a voltage to be supplied to a spark plug that is provided in an internal combustion engine on the basis of a pulse signal induced in the ignition coil of the internal combustion engine, wherein the ignition control apparatus comprises at least a switch element for passing current through and discharge the ignition coil, and a controlling unit that acquires the timing for discharge the ignition coil in response to a first pulse of the pulse signal, and controls the switch element so that a current flows through the ignition coil in response to a second pulse that follows the first pulse and the ignition coil is opened on the basis of the discharge timing acquired in response to the first pulse.

Abstract: There is provided an internal combustion engine ignition apparatus that can effectively raise the ignitability of an inflammable fuel-air mixture, by applying electric power corresponding to the combustion state of an internal combustion engine. A combustion state detection apparatus detects an combustion state inside a combustion chamber of the internal combustion engine; based on the combustion state detected by the combustion state detection apparatus in accordance with an operation state of an ignition coil apparatus, a current supply apparatus supplies an AC current to a spark discharge path formed in the gap of an ignition plug; then, a control apparatus controls the output of the current supply apparatus.

Abstract: Methods and systems are provided for an EGR system including an EGR cooler module directly mounted to a cylinder head. In one example, the EGR cooler module includes an EGR inlet port, an EGR outlet port, a coolant inlet port, and a coolant outlet port all arranged parallel with each other and directly mounted to a first side of a cylinder head to interface with passages internal to the cylinder head. In another example, the EGR cool module includes an EGR inlet port and a coolant inlet port parallel to each other and directly mounted to a first side of a cylinder head to interface with passages internal to the cylinder head, while also including an EGR outlet port and a coolant outlet port to interface with passages external to the cylinder head.

Abstract: A vehicle having a valve stop mode control unit configured such that an intake valve and an exhaust valve are stopped in a closed state during rotation of an output shaft, supply of fuel to an engine is stopped, a clutch is made to be in an engaged state, and pistons are driven by rotational forces from driving wheels through the output shaft. When there is a request for valve stop inertial running, a negative pressure is supplied to an intake passage by a vacuum pump.

Abstract: A fuel injection valve (6) is configured such that the effective opening area of an injection port (61) increases as its lift amount increases. A fuel injection control unit (an engine control unit 100) injects fuel in a lift amount changing mode wherein, when fuel is injected into a combustion chamber (17) in the terminal period of the compression stroke, the lift amount of the fuel injection valve is set to a predetermined large lift amount in the earlier period of the injection period, and in the later period of the injection period following the earlier period of the injection period, the lift amount is set to a small lift amount smaller than the large lift amount and is in a range where the fuel injection speed increases.

Abstract: Systems and methods for improving combustion in a highly exhaust gas diluted engine are disclosed. The methods and systems may be provided in an engine that is supplied two different types of fuel.

Abstract: A hydraulic lash adjuster for an engine valve train has a hydraulic lash adjusting arrangement for automatically compensating for lash in an engine valve train, and a lost motion arrangement for inhibiting motion induced in the valve train in response to a lift profile of a rotating cam from being transferred to an engine valve.

Abstract: An ejector for vaporized fuel gas recirculation devices is provided. The ejector for vaporized fuel gas recirculation devices reduces the number of elements equipped in a vehicle and an ejector mounting angle is adjusted to be suitable for a layout environment of the vehicle. Accordingly, a mounting cavity of the vehicle is more efficiently designed. When an intake pressure of an intake manifold is reduced a base component is moved in a direction toward a first nozzle component, and a region of the base component except an aperture closes the first nozzle component.

Abstract: In one aspect, a skip fire engine controller is described. The skip fire engine controller includes a skip fire module arranged to determine an operational firing fraction and associated cylinder load for delivering a desired engine output. The skip fire engine controller also includes a firing controller arranged to direct firings in a skip fire manner that delivers the selected operational firing fraction. Various methods, modules, lookup tables and arrangements related to the selection of a suitable operational firing fraction are also described.
