摘要：

An experimental study has been established to understand the effective cylinder wall heat transfer rate and temperature of a direct injection diesel engine. Temperatures were calculated under a wide range of load at different locations in the cylinder block and cylinder head of the engine using pre-arranged thermocouples to acquire the temperature gradient and consequently realize the equivalent heat transfer rate, cylinder wall temperatures, heat transfer coefficient and engine speed. Diesel and biodiesel blends (B20 and B100) are used as fuels and the temperature readings are found using a ‘k-type’ thermocouple and temperature readings are noted. Raise in the cylinder temperature is observed as the engine torque increases for the diesel and biodiesel. As the engine speed increases, the exhaust gas velocity involved in and out of the engine will increases and this lead to an increase in the heat transfer co-efficient for diesel and biodiesel. © 2020.
