Methods and systems are provided for using compression heating to heat a cylinder piston before cylinder combustion is resumed. Cylinder heating is achieved using combinations of slow unfueled engine rotation where the engine cylinders are heated via compression stroke heating, and slow compressor rotation where the cylinders are heated via compression heating. One or more intake or exhaust heaters may be concurrently operated to expedite cylinder heating.

A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

Methods, systems, and apparatus for providing an acceleration boost. The acceleration boosting system provides or outputs a boosted acceleration. The acceleration boosting system includes a communication device, a navigation unit or a first sensor that is configured to obtain acceleration information. The acceleration boosting system includes a second sensor that is configured to detect or measure an applied force of an accelerator pedal. The applied force corresponds to a first amount of energy that is used to power or propel the vehicle. The acceleration boosting system includes an electronic control unit that is configured to determine that the acceleration information indicates that a driver should accelerate. The electronic control unit is configured to determine that the accelerator pedal is depressed within a threshold time limit of the indication and cause a second amount of energy to be converted to move or propel multiple wheels.

A host vehicle includes an internal combustion engine, a turbocharger in fluid communication with the internal combustion engine, a communication system configured to transmit and receive a traffic-related message, and a controller in communication with the turbocharger and the communication system. The controller is programmed to: receive the traffic-related message via the communication system; and command the internal combustion engine to increase a power output to spool up the turbocharger in response to receiving the traffic-related message. The controller is programmed to determine a number of relevant vehicles. The number of relevant vehicles is a number of vehicles that are in front of the host vehicle and behind a traffic light and affect a movement of the host vehicle toward the traffic light. The traffic-related message is a one of a vehicle message from another vehicle and/or a traffic-light message from the traffic light.

A hybrid vehicle includes an engine with cylinders generating driving power and a turbocharger having a turbine in an exhaust line, and a compressor which rotates with the turbine and compresses intake gas. An electric supercharger is disposed in the intake line upstream from the compressor, a catalytic converter is disposed in the exhaust line downstream from the turbine. A post processing bypass line connects the exhaust line at a downstream portion of the catalytic converter and the intake line at a downstream portion of the electric supercharger. A low pressure EGR device includes a low pressure EGR line branching off from the exhaust line and merging into the intake line and a low pressure EGR cooler disposed therein. A high pressure EGR device includes a high pressure EGR line branching off from an exhaust system and merging into an intake system, and a high pressure EGR cooler disposed therein.

An electricity generation system includes an internal combustion engine and at least one electricity generation motor that generates electricity upon an input shaft thereof being rotated by the internal combustion engine, wherein the internal combustion engine includes: a piston reciprocable in a cylinder; a valve actuating mechanism that actuates an intake valve and exhaust valve; a supercharger that compresses intake air to be delivered into the cylinder; and a fuel feeder, and wherein while the piston reciprocates once by starting from a top dead center and returning to the top dead center, the valve actuating mechanism actuates the intake and exhaust valves in such a manner as to provide a valve overlap period, the fuel feeder feeds fuel into the cylinder after closing of the exhaust valve, and an air-fuel mixture inside the cylinder is burned during a period in which both of the intake and exhaust valves are closed.

An aircraft propulsor that includes an exhaust combustor is disclosed. The aircraft propulsor can include an internal combustion engine and a turbocharger. The turbocharger can be spooled while motoring the internal combustion engine. For example, when restarting the internal combustion engine at high altitude, an injector and an igniter can provide fuel to the exhaust and combust fuel to spool the turbocharger, decreasing load on the engine during restarting. In another example, an electric turbocharger can be driven with an electric motor to spool the turbocharger.

An ECM executes a catalyst early activation control at the cold start of an engine such that the activation of a catalyzer is promoted by opening a WGV. Further, the ECM performs a diagnosis process of diagnosing whether or not the WGV is stuck closed, based on the amplitude of the output fluctuation in an air-fuel-ratio sensor during execution of the catalyst early activation control.
