System Introduction

The engine fuel constant temperature system is mainly used for fuel temperature control in engine performance testing, which provides a certain guarantee for the good repeatability of engine performance testing. The fuel in the fuel tank of the engine laboratory passes through the fuel consumption meter, flows into this device together with the engine return oil, enters the heat exchanger for heat exchange, and then enters the engine. There is a temperature sensor at the outlet of the heat exchanger, which transmits the measured fuel temperature to the thermostat and compares it with the set fuel temperature inside the thermostat. According to the comparison results, the thermostat automatically adjusts the temperature of the circulating water flowing through the heat exchanger, gradually aligning the oil temperature with the set temperature, thereby achieving the goal of controlling the fuel temperature.

The engine fuel constant temperature system can be divided into two types: forced cooling and water cooling. The forced cooling type provides a cooling source through its own refrigeration system, while the water cooling type requires external supply of chilled water within a specified temperature range.

Users can use the computer TS232/485 serial interface to adjust or set system parameters and program control.
