An engine control system for an engine includes: a pump control module configured to control a coolant pump; a block control module configured to control opening of a block valve; a fuel control module configured to control fueling of the engine; a coolant control module configured to control a position of a coolant valve; and an adjustment module configured to, when the coolant pump is pumping, the block valve is open, and the coolant valve is positioned such that an input is connected to an output, adjust the fueling of the engine such that fueling of the engine is fuel rich.

An electric motor-vehicle coolant pump includes a pump housing with a flow housing part and a separate motor housing part, a spiral flow channel with an axial inlet and a tangential outlet, a rotatably supported fluid-conveying element, an electric drive motor which drives the rotatably supported fluid-conveying element, and a mounting structure which mounts the pump housing to a vehicle structure. The mounting structure is only arranged on the flow housing part. The flow housing part at least partially surrounds the spiral flow channel and at least partially surrounds the rotatably supported fluid-conveying element. The separate motor housing part surrounds the electric drive motor.

A hybrid pump apparatus (100) having a pump subassembly having an inlet and an outlet an electrical drive (110) arranged to selectively drive the pump subassembly, a mechanical drive comprising a driven member (104) configured to receive a drive torque; and a clutch (160) in a load path between the driven member and the pump subassembly, the clutch being movable between a first condition in which the driven member drives the pump subassembly and a second condition in which the driven member can rotate freely relative to the pump sub assembly in which the clutch is a dog clutch.

A pump device for a cooling circuit of an internal combustion engine of a commercial or motor vehicle includes two electric pumps in parallel, each of which includes a switchable backflow valve in a suction line, so that the electric pumps can be operated selectively individually or in parallel.

An auxiliary coolant pump for circulating a coolant in a vehicle thermal system having a main coolant pump includes a housing, an impeller, a motor selectively driving the impeller, a coolant inlet configured to receive the coolant, a coolant outlet fluidly coupled to the coolant inlet, and a bypass passage fluidly coupled between the coolant inlet and the coolant outlet. When the main coolant pump is on, the auxiliary coolant pump is selectively turned off such that coolant flows through the bypass passage to reduce or eliminate restriction of the coolant flow rate in the thermal system. When the main coolant pump is off, the auxiliary coolant pump is selectively turned on such that coolant continues to flow through at least a portion of the thermal system.

When a coolant controlled to have a constant target temperature is used regardless of a traveling condition of a vehicle, a fuel efficiency of the vehicle may be reduced. Therefore, a VCU 1 predicts the output of an internal combustion engine in a future prediction period on the basis of position information of the vehicle acquired from a positioning unit, traffic information related to a route to a destination, and internal combustion engine control information, determines a target coolant temperature which is the target temperature of the coolant for cooling the internal combustion engine on the basis of the predicted output of the internal combustion engine, sets the change timing for changing the temperature of the coolant to the target coolant temperature on the basis of the predicted output of the internal combustion engine, and controls the operation of the coolant temperature change unit for changing the temperature of the coolant at the change timing so as to reach the target coolant temperature on the basis of the predicted output of the internal combustion engine.
