A heater control apparatus of a fuel filter for a vehicle includes a heater mounted within a fuel filter; a relay for a heater power source supplying or interrupting power of a battery to or from the heater; a fuel temperature detection sensor mounted on an engine and detecting a temperature of a fuel; and an engine electronic control unit (ECU) for switching on and off the relay based on a detection signal of the fuel temperature detection sensor.

A system according to the principles of the present disclosure includes a pump control module and a fuel vaporization module. The pump control module controls a first pump to deliver fuel from a fuel tank to a second pump through a fuel line. The pump control module controls the second pump to pressurize fuel from the fuel line and to deliver the pressurized fuel to a fuel rail. The fuel vaporization module determines whether fuel at an inlet of the second pump is vaporizing based on an engine operating condition. The pump control module increases an output of the first pump when fuel at the inlet of the second pump is vaporizing.

A thermal management system for controlling cooling of an engine system during shutdown, the engine system includes an engine configured to provide power to a working machine, wherein the thermal management system includes a controller which is configured to receive a signal indicative of an engine shutdown command. The controller is further configured to derive, infer or receive a temperature parameter of the engine system and to determine whether the temperature parameter of the engine system is above a first predetermined threshold; and wherein the controller is configured to signal the progressive reduction of a speed of the engine prior to issuing a signal to shutdown the engine in the event that the first predetermined threshold is exceeded when the engine shutdown command is received, thereby cooling the engine system prior to engine shutdown.
