Development of Four Stroke Four Cylinder HSDI Diesel Engine Test Bed
The test bed for the HSDI diesel engine is developed in this study. Also in this study the energy balance on the HSDI diesel engine is done. Energy balance is done at various speeds of the engine. Performance parameters of the engine are calculated on the test bed at various speeds. Calibration of the flowmeters (orificemeter and turboflowmeter) is done in this study. It is found that coolant losses and exhaust losses are high at low loads and other losses like radiative losses are high at high loads. Brake power increases with loads increase in load on the engine. Coolant losses as well as exhaust losses are high at low engine speed and they are small at high engine speed.
