Systems and methods for preparing an engine for a cold start are described. In one example, the air is injected into one or more pre-chambers of engine cylinders in response to an engine start request so that one or more cylinders may be heated before the engine is started. The engine may or may not be rotated while air is being injected to pre-chambers of engine cylinders.

A control method and a control apparatus are provided. A main control circuit board in a controller receives an initial control command via a CAN bus from an ECU after being powered on, controls a fault detection circuit board to detect initial states of the controller and all devices connected to the controller based on the initial control command to obtain initial state information, transmits the initial state information to the ECU via the CAN bus, receives a first target control command via the CAN bus from the ECU, and controls a conduction control circuit board to turn on at least one MOS in a MOS array based on the first target control command to output a control signal to a heater connected to the controller to control the heater to operate, thereby realizing a closed-loop control on the heater and adjusting a power of the heater at any time.

A vehicle system includes a sensor that measures an engine block heating characteristic associated with an engine block heater. A processing device is programmed to determine an operating state of the engine block heater based on the engine block heating characteristic measured. A communication device is programmed to transmit a message that includes the operating state of the engine block heater.

A diesel engine, in particular a high-power diesel engine, which has a variable valve train including an adjusting unit for adjusting a valve opening time, a valve lift, a camshaft phase position and/or a valve steering, and a control or regulating unit for controlling the adjusting unit. The control and/or regulating unit includes at least one operational mode provided for starting the engine when the engine is at a low temperature, in which the control and/or regulating unit is provided to adjust the valve opening time, at least during a preliminary phase for at least one inlet valve, which overlaps at least with one compression stroke of an associated cylinder, and to interrupt an injection of fuel at least into the cylinder associated with the inlet valve. The invention also relates to a method for starting such a diesel engine.

Methods and system for providing heat to a vehicle are presented. In one example, a heat pump supplies thermal energy to an engine to reduce engine emissions during engine starting. Further, heating the engine via the heat pump may also reduce engine friction at colder ambient temperatures where oil viscosity may be increased.
