A reciprocating, internal combustion engine comprises a turbine connected to the exhaust port of a cylinder. The turbine receives exhaust gas from the cylinder and a power capture means transfers the power generated by the turbine to at least one of power storage device, a turbocharger, a compressor, and vehicle locomotion.

A two-cycle motor (10) has cylinder assembly (20) housing piston assembly (30) therein that moves reciprocally between two extreme positions controlled by a crankshaft. Cylinder assembly (20) includes combustion chamber (25) and an air compression chamber (45) in an enlarged annular portion (40). Portion (40) receives flange (31) integrally and radially outwardly extending from piston assembly (30) to define to air compression sub-chambers (47;47a). One-way inlet valve assemblies (41, 42) alternate to allow air in while outlet one-way valve assemblies (41a-42a) supply the compressed air to tank assembly (80) for release of the compressed air through intake one way valve assembly (29) to combustion chamber (25).

A residual gas ignitor for use in igniting a fuel-air mixture within a main combustion chamber of an engine. The residual gas ignitor includes at least one inlet/outlet port, a residual gas ignitor chamber for receiving a combustion gas from the main combustion chamber, an ignitor valve for opening and closing the at least one inlet/outlet port, an actuator for actuating the ignitor valve to open and close the at least one inlet/outlet port, a valve guide for keeping the ignitor valve in a correct orientation within the residual gas ignitor, a preload spring for being in compression when the actuator disposes the ignitor valve into the closed position, and a heating element for maintaining or increasing a temperature of the combustion gas while the combustion gas is in the residual gas ignitor chamber. The residual gas ignitor may be used in engines for initiating combustion of fuel-air mixtures.

Methods and systems are provided for controlling airflow of an accumulator of a motorized vehicle. In one example, a method includes storing pressurized gases within the accumulator by flowing intake air from a compressor of an engine of the vehicle to a pressure booster arranged upstream of the accumulator. Pressurized gases stored within the accumulator may be used to drive one or more pneumatic devices.

A method for controlling a turbocharger system fluidly connected to an exhaust manifold of a combustion engine and an exhaust after treatment system. The turbocharger system comprises a turbocharger turbine operable by exhaust gases from the exhaust manifold, and a tank with pressurized gas, the tank being fluidly connectable to the turbocharger turbine. The method comprises the steps of: determining a NOx parameter being indicative of, or correlated to, NOx emissions from the exhaust after treatment system; and injecting pressurized gas from the tank to drive the turbocharger turbine based on the determined NOx parameter, wherein a determined NOx parameter above a pre-defined first threshold determines that pressurized gas from the tank is injected.

Methods and systems are provided for a prechamber. In one example, a system comprises a reservoir fluidly coupled to a prechamber and a compressor. The reservoir is configured to store boost air or residual gases.

An internal combustion engine having at least one cylinder that has a main combustion chamber for burning a fuel/air mixture or a fuel/air/exhaust gas mixture and has a flushed prechamber connected to the main combustion chamber via at least one overflow duct on the fluid side. At least one exhaust gas turbocharger is provided that has a turbine for the expansion of the at exhaust gas leaving the at least one cylinder and a compressor for compressing fresh air or a fresh air/exhaust gas mixture to be supplied to the at least one cylinder as compressed charge-air. In a charge-air line downstream of the compressor, an extraction point is formed from which a flushing line branches off, via which a partial amount of charge-air of the compressed charge-air for flushing the at least one prechamber can be extracted.
