Research and Application of the Auto-control Cooling System for the Diesel Engine

摘要

In order to solve the problem that the traditional cooling system cannot adjust the cooling water temperature to the different operation conditions of diesel engine, the auto-control cooling system is designed. Using it, the coolant temperature can be adjusted automatically by the single-chip which controls the transducer-controlled pump and the electronic dividing valve which replaces the thermostat. We use the thermal equilibrium bench to verify the figures, and the result is show that using the exhaust of generator heats the cooling water can shorten 3 minutes in starting process and the cooling water temperature adjusted automatically to the changing operation conditions of diesel can decrease the fuel consumption remarkably, the highest fuel saving rate reached 5.4%, the averagely fuel saving rate reached 3.6%.
