Heavy equipment uses diesel engines as the main power source. Common problem in diesel engines is engine overheat condition and the cause of this problem can come from thermostat failure. Diagnosis of the thermostat when problem occurs in the diesel engine cooling system requires a long time. This study aims to determine the condition of the coolant flow and monitor thermostat performance while engine is running so thermostat failure can be detected earlier. In this study, an ultrasonic flow meter to measure coolant flow rate in the diesel engine cooling system was developed and the measuremen

Abstract:

The engine cooling system must be able to match up with the stable operating conditions so as to guarantee the engine performance. On the working cycle level, however, the dynamic thermo-state of engines has not been considered in the cooling strategy. Besides, the frequent over-cooling boiling inside the gallery changes the cooling capacity constantly. It is necessary to study the coupling effect caused by the interaction of cooling flow and in-cylinder combustion so as to provide details of the dynamic control of cooling systems. To this end, this study develops a coupled modeling scheme of

Abstract:

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 13 minutes in starting process and the c

Abstract:

There are several strategies have been developed in the automotive cooling system to improve engine thermal management. Basically, these designs use controllable actuators and mechatronic components such as electric water pump, controllable thermostat, and controllable electric fan to improve engine temperature control on most operating ranges. Most of the strategies are complicated and costly. This paper introduced a different approach to improve coolant temperature warm-up during cold start. The new strategy was by promoting a higher coolant flow rate inside the engine block by just installi
