An engine startup system for a vehicle includes: a cold start module configured to selectively generate a cold start command when an ambient air temperature is less than a predetermined temperature; a starter control module configured to, in response to the generation of the cold start command…
A control signal is issued to a turbo shaft actuator to rotate a turbine at a first turbine speed in response to an ignition turn on signal. The first turbine speed is different from a default turbine speed. The rotation of the turbine at the default turbine speed results in exhaust gas having a…
Control signals are issued to open a wastegate, rotate a turbine, and turn on a catalyst heater disposed between the turbine and a catalyst in response to a trigger signal. The rotation of the turbine causes recirculated air flow in a recirculation flow path including an exhaust manifold, exhaust…
An internal combustion engine system includes an internal combustion engine, an exhaust aftertreatment system with a catalytic converter configured to receive exhaust gas from the internal combustion engine, and a light-off catalyst system including an electrolyzer configured to perform an…
An engine system that delivers torque to a driveline of a vehicle includes an internal combustion engine (ICE), a manifold, a compressor and a controller. The manifold selectively communicates air into the ICE. The compressor is driven by an electric motor and is configured to deliver air toward…
For an in-cylinder direct injection spark ignition internal combustion engine including an intake port provided with a tumble control valve, a startup control method is presented. When a startup of the engine satisfies a predetermined cold start condition requiring a retard operation of the engine…
The invention relates to a method for operating a compression ignition internal combustion engine (10) including at least one combustion chamber (18) with a fuel injector (20) for direct fuel injection into a combustion chamber (18), an electronic control unit (ECU) for controlling the fuel…
A direct fuel injection/spark ignition engine control device is configured to enable compression stroke injection when the fuel pressure is low at startup and immediately after startup, and to reduce the wall flow and amount of HC exhaust. When the catalyst requires warming, fuel is injected in the…
An engine control device (20) is configured to perform optimum combustion control according to environmental conditions when warming up of a catalyst for emission purification is required. The engine control device (20) performs stratified combustion by the compression stroke injection at the time…
