A pressure relief valve is provided. The pressure relief valve includes a hollow body having an inlet and an outlet, with the hollow body including at least one aperture extending through a surface of the hollow body. An actuator assembly is attached to the hollow body and a sleeve is slideably positioned about the hollow body, with the sleeve moveably attached to the actuator assembly. During operation, the actuator assembly moves the sleeve from a first position that covers the aperture to a second position that un-covers at least a portion of the aperture.

One aspect of the present disclosure relates to a power electronics device for an electrically-driven charging device for an engine, said power electronics device comprising one or more power electronics components which are designed to operate an electrically-driven charging device for an engine, first and second conductors for guiding current for the one or more power electronics components, and a throttle for filtering electromagnetic interference. The throttle has a magnetic core which forms a closed ring about the first and second conductors and comprises a tongue which extends, arising from the closed ring, between the first and second conductors.

An engine includes fuel system components provided on a cylinder head, a purge control valve that controls an amount of evaporated fuel purged to a portion of an intake passage on a downstream side of a throttle valve, and intake pipes that form the portion of the intake passage on the downstream side of the throttle valve and extend in a cylinder array direction, in which the purge control valve is disposed in front of the intake pipes and the fuel system components are disposed on an opposite side of the purge control valve across the intake pipes in vehicle front view or vehicle side view.

A method of implementing control logic of a compression-ignition engine is provided. A control part of the engine performs a calculation according to the control logic corresponding to an engine operating state in response to a measurement of a measurement part, controls a fuel injection part, a variable valve operating mechanism, an ignition part and a supercharger so that a G/F becomes leaner than a stoichiometric air fuel ratio and a A/F becomes equal to or richer than the stoichiometric air fuel ratio, while causing the supercharger to boost, and controls the ignition part so that unburnt mixture gas combusts by self-ignition after the ignition. The method includes determining a supercharging pressure P, and determining control logic defining a close timing IVC of an intake valve. When determining the control logic, the close timing IVC (deg.aBDC) is determined so that the supercharging pressure P (kPa) satisfies the following expression: P8.010.sup.11IVC.sup.61.010.sup.8IVC.sup.5+3.010.sup.7IVC.sup.44.010.sup.6IVC.sup.3+0.0068IVC.sup.20.3209IVC+116.63.

A supercharging device for an internal combustion engine having a compressor that is driven by an electric motor for supercharging the internal combustion engine with air via an air feed passage, and an electric energy accumulator, which is fed with electric energy via a first power generator that is driven by the internal combustion engine.

A split-cycle internal combustion engine includes a variable displacement compressor having two or more cylinders, an adjustment mechanism for varying the displacement volume of the compressor and possibly the phase between the compressor and the motor, and a rotary motor having two or more expansion chambers. A passage valve system located between the compressor and the motor transfers working fluid and combustion exhaust products, and, in addition, mechanically and thermally isolates the compressor from the high pressures and temperatures present in the motor.

A boost system for providing boost pressure to an air intake manifold of an engine includes a supercharger having rotors and a supercharger input shaft, an electric motor/generator, and a planetary gear set. The planetary gear set operates to transfer torque between the supercharger input shaft, the electric motor/generator and a crankshaft of the engine. The boost system can have a compact configuration.
