Filtration equipment for diesel motor fuel - has main heat exchanger for filtered fuel and heating water with three loop cycles for latter leading through valves and other heat exchange

摘要

The diesel motor fuel filtration equipment includes in one embodiment, a heat exchanger (17), with one loop connected between a three-way thermostatic valve (15) and a second thermostatic stave (33), which returns the cycle to the motor unit (11). The latter has a coolant water inlet (12) and an outlet (13) forming a short (first) loop through a conduit (14) to the three-way valve. The second (long) loop includes the cooler (22), three-way valve (15) and side conduit (23) in the line from the pump (18) and water inlet (12). A third coolant loop comprises the second thermostatic valve (33) aforementioned and has a parallel line through a heating exchanger (36) and the heating valve (35). The main heat exchanger (17) cycle includes a filter (16), fuel injection pump (24) and the injection unit (27) adjacent to the motor.
