Methods and systems are provided for a heating device. In one example, a system comprises a heat exchanger and an air filter arranged in a common housing, wherein the heat exchanger is configured to receive coolant from a heating device. In one example, the heating device is an electric heating device.

An engine system capable of controlling an intake air flow includes a combustion chamber, an ignition plug, an intake air flow control valve, and a controller. The controller performs, in at least a part of an operating range, SPCCI combustion in which after jump-spark ignition combustion of a portion of a mixture gas inside the combustion chamber by a jump-spark ignition of the ignition plug, compression ignition combustion of the remaining mixture gas is carried out by a self-ignition. The controller strengthens, at least in a part of the operating range of SPCCI combustion, the intake air flow inside the combustion chamber by controlling the intake air flow control valve. The controller controls, in a middle-load range of the operating range where SPCCI combustion is performed, the intake air flow control valve so that the intake air flow becomes weaker than in a high-load range and a low-load range.

Internal combustion engine with at least one turbocharger having a compressor, a bypass valve by means of which the compressor can be bypassed by at least a partial flow of a fuel mixture provided for the combustion, and a control or regulating unit connected to the bypass valve for regulating or controlling a degree of opening of the bypass valve, whereby the control or regulating unit is designed to open and/or at least partially keep open the bypass valve when starting the internal combustion engine.

The intake increasing device 100 pertaining to the present invention is for increasing air intake of an engine, and is provided with, a cylindrical wall part 20 having an intake inlet 20in and an intake outlet 20out, the wall part 20 leading intake air from the intake air inlet 20in to the intake air outlet 20out, an ejection port 30 for ejecting air F2 flowing along an inner circumferential surface 21 of the wall portion 20 to an air intake downstream side, the ejection port 30 being provided in the wall part 20; and a fan 40 for sending air to the ejection port 30.

Methods and systems are provided for de-icing a charge-air cooler of a boosted engine system when the engine is turned off. In one example, a method may include recirculating air through a bypass passage including an activated electric supercharger and the CAC. The air is warmed by compression and thaws ice accumulated in the CAC.

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.

An engine system includes an engine including one or more cylinders for generating a driving torque, a plurality of intake lines for supplying external air to the one or more cylinders, and one or more electric superchargers disposed on, or in, the plurality of intake lines.

A method of operating a forced induction gaseous-fueled engine includes mixing gaseous-fuel and engine intake air to form a mixture at a fuel mixer. The method includes delivering the mixture to an intake manifold by at least partially bypassing a charge air cooler.

A control system and method for controlling vehicle launch includes receiving a request to enable a launch control feature of a traction control system of the vehicle, the launch control feature being configured to improve torque transfer from an engine of the vehicle to a driveline of the vehicle; and in response to receiving the enable request for the launch control feature, generating a torque reserve at the engine by (i) increasing airflow into the engine to a level greater than a level for achieving a torque request for the engine and (ii) deactivating a predetermined set of cylinders of the engine by disabling their respective fuel injectors; detecting an intent of the driver to launch the vehicle; and in response to detecting the intent of the driver to launch the vehicle, releasing the torque reserve to increase a torque output of the engine based on the engine torque request.
