摘要： A rotary valve provides single point flow control of coolant within the cooling system of an internal combustion engine. The valve distributes coolant flow from the engine in predetermined flow modes to either 1) the radiator and heater simultaneously, 2) a bypass circuit only, 3) the heater only, or 4) the radiator and bypass simultaneously. The single-point coolant control results in advantages of shorter warm-up times, a lower pressure drop (reducing power consumption by the pump), reduced engine emissions and fuel consumption, improved cabin heater performance, and improved engine durability due to reduced thermal shocks to the engine components by virtue of more precise control of engine operating temperature.

摘要： The present application relates to a fuel injection system of an internal combustion engine having an automatic stop-start system, the fuel injection system comprising a high pressure fuel pump, which via a fuel pump line delivers fuel towards a common fuel rail, to which a fuel return line is connected. It is proposed that the fuel return line comprise a control element system, which firstly discharges a fuel pressure to a fuel tank, when a first predefined pressure limit is reached in the fuel return line, and which secondly prevents a further flow of fuel from the return line into the fuel tank, but allows a flow of fuel from the fuel tank into the fuel return line, so that the return line is designed as a fuel pressure accumulator.
