An electronic control unit is configured to select one of a series mode, a series-parallel mode and a parallel mode as a running mode. A load level of a hybrid vehicle is set to a value that is high in the order of a load level at which the parallel mode is selected, a load level at which the series-parallel mode is selected, and a load level at which the series mode is selected. That is, the electronic control unit selects the series-parallel mode in an intermediate load region, selects the series mode in a low load region, and selects the parallel mode in a high load region.

A controller for an internal combustion engine is configured to control the fuel injection valve so that the fuel injection valve selectively performs partial lift injection, which does not open a valve member at a fully open position, and full lift injection, which opens the valve member at the fully open position. The internal combustion engine includes the fuel injection valve and a fuel supply system. The controller includes an energizing time setting unit, a fuel pressure calculation unit, and a smoothening process unit. The energizing time setting unit is configured to set an energizing time for the full lift injection based on graded fuel pressure calculated by the smoothening process unit and set an energizing time for the partial lift injection based on fuel pressure calculated by the fuel pressure calculation unit.

A continuously variable valve duration (CVVD) system includes an electronic control unit (ECU) configured to output a command for adjusting an actuator and a controller configured to determine a operation range of a control shaft of the actuator and adjust the control shaft in the determined operation range based on the command of the ECU. The controller positions the control shaft at a predetermined target phase and determines a control state of each target phase based on a target phase value transmitted from the actuator when the control shaft is positioned at the target phase.

A vehicle includes electric brakes, an engine with a starter, a battery and a controller. The battery has a voltage and is configured to power the starter, the electric brakes, and the controller. The controller is configured to, in response to a speed of the vehicle falling within a specified range without propulsive demand and while the voltage is greater than an upper voltage that varies based on a charge needed to engage the brakes to stop the vehicle, stop the engine.

An integrated load bank and exhaust heater for a diesel genset exhaust aftertreatment system of the type having a diesel particulate filter (DPF) and a selective catalytic reduction (SCR) section. The load bank/heater can function as a load bank when testing the genset, as a heat source to optimize SCR efficiency, as to thermally regenerate the DPF filter.

An internal combustion engine for driving a working assembly with a clutch, including a combustion chamber into which a mixture of fuel and air is supplied, a spark plug to ignite the mixture, ignition of the mixture driving a piston operably coupled to a crank portion of the engine, a fuel supply system including a fuel valve and a throttle valve, a throttle position sensor configured to determine a position of the throttle valve, a speed sensor configured to determine engine speed, and an electronic control unit configured to control operation of the fuel valve and the spark plug, the electronic control unit being configured to initiate a speed limitation operation in response to a first position of the throttle valve at engine start-up, wherein the speed limitation operation continues until the throttle valve is moved from its first position.

A method for starting an internal combustion engine comprises the steps of: providing an internal combustion engine having at least one cylinder and a piston supported at a crankshaft for repeated reciprocal movement in the cylinder so as to define a main combustion chamber, the internal combustion engine further having an ignition device arranged in said cylinder with an igniter portion and a fuel injector which are both arranged at a pre-chamber, wherein the pre-chamber has a plurality of orifices for providing fluid communication between said pre-chamber and the main combustion chamber, injecting fuel in the pre-chamber, and igniting the injected fuel in the pre-chamber for pre-heating of the pre-chamber prior to injecting fuel in the main combustion chamber for combusting the injected fuel in the main combustion chamber.

A method and system are provided with which it is possible to detect non-firing and untimely firing events in internal combustion and, if necessary, the temperature of the gas in the exhaust gas pipe. This is performed in general by measuring the speed of sound and determining the phase angle between the sender and receiver either arranged on different sides of the exhaust gas pipe or on the same side of the exhaust gas pipe. The receiver, depending on the measurement principle, can include one, two, or in special applications three receivers. Additionally, if necessary, it is possible to suppress the structure-borne sound influence on a speed of sound measurement with low cost and high stability.

A fuel injection valve control device controlling a fuel injection valve that injects a fuel into a combustion chamber includes an operation-condition calculation portion that calculates a fuel injection condition of the fuel injection valve based on a crank angle detected by a crank angle sensor that detects the crank angle of an engine, a current-waveform setting portion that sets a current waveform of a current supplied to the fuel injection valve on the basis of the fuel injection condition calculated by the operation-condition calculation portion, and so on. The current-waveform setting portion sets the current waveform so as to set a temporal change of a pickup current of a needle provided in the fuel injection valve to be equal to or less than a predetermined reference value when a fuel injection start timing is equal to or more than 180 degrees BTDC. The current-waveform setting portion sets the current waveform so as to set a temporal change of the pickup current of the needle to be more than the predetermined reference value when the fuel injection start timing is smaller than 180 degrees BTDC.

A number of variations may include a method comprising selectively actuating an inlet swirl device to cause a compressor to windmill at a higher speed during an operation mode where fuel consumption of an engine in the vehicle is at a minimal or before an acceleration event.
