A method for managing emissions from a vehicle having an aftertreatment system is provided. The method includes: receiving, by a controller, information indicative of a temperature of an aftertreatment system of the vehicle and a power output of an engine of the vehicle; comparing, by the controller, the temperature of the aftertreatment system to a temperature threshold; comparing, by the controller, the power output to a power output threshold; and responsive to the comparisons, commanding, by the controller, an aftertreatment system heater to selectively engage and disengage to warm the aftertreatment system of the vehicle.

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.

An injection assembly for a vehicle exhaust system includes a housing defining a fluid cavity, a doser mounted to the housing and configured to inject a fluid into the fluid cavity, and a valve to control flow of the fluid. The valve is moveable between an open position and a closed position. A resilient member is configured with a biasing force to bias the valve to the closed position. The biasing force is overcome when fluid is heated downstream of the valve and exceeds a predetermined pressure level to allow backflow into the fluid cavity.

A method to control the combustion of a compression ignition engine having the steps of: establishing, for each combustion cycle, a fuel quantity to be injected into the cylinder; injecting a first fraction of the fuel quantity; heating a second fraction of the fuel quantity, which is equal to the remaining fraction of the fuel quantity, to an injection temperature higher than 100° C.; injecting the second fraction of the fuel quantity heated to the injection temperature into the cylinder at the end of the compression stroke and at no more than 60° from the top dead centre; and decreasing the injection temperature and the ratio between the second fraction and the first fraction as the internal combustion engine increases and as the rotation speed of the internal combustion engine increases.

A preheating device for preheating the fuel of an internal combustion engine with a heating medium has a fuel transport device with a fuel inlet and a fuel outlet, and has a fuel transport channel connecting the fuel inlet and the fuel outlet. The preheating device also has a heating medium transport device with a heating medium inlet and a heating medium outlet, as well as a heating medium transport channel connecting the heating medium inlet and the heating medium outlet and/or at least one heating element. The fuel transport device and the heating medium transport device and/or the at least one heating element are in thermal contact with each other and thus form a heat exchanger via which a fuel transported in the fuel transport device can be heated by a heating medium transported in the heating medium transport device and/or by the at least one heating element.

Methods and systems for operating an engine with an electrically driven compressor are described. In one example, output of the electrically driven compressor is adjusted to increase a temperature of an engine so that the engine may be started without glow plugs or with glow plugs that have a lower heat capacity output. Additionally, a position of a recirculation valve may be adjusted to increase the temperature of the engine.
