Fuel circuit with thermostat-controlled fuel pre-heating for an air-compressing injection internal combustion engine

摘要

The invention relates to a fuel circuit with thermostat-controlled fuel pre-heating for an air-compressing injection internal combustion engine, in which a reversing valve, controlled as a function of the fuel temperature, for diverting the fuel by way of a heat exchanger and an intake filter downstream of the reversing valve are arranged in a flow line leading to the feed pump, it being possible for fuel, controlled by way of the heat exchanger, to flow through the intake filter in order to avoid the risk of clogging.
