摘要

The size of droplets of vegetable oil spray injected from the injection nozzle plays a significant role in the performance of diesel engines. Now, three kinds of the injection nozzles are used according to the combustion chamber type of the diesel engine in the world pintle, throttle and hole nozzles. This paper deals with the relationship between the droplets size of the injected spray and the injection nozzle types using two kinds of vegetable oils and the mixture of diesel oil and each of these two different vegetable oils. The results show that there was a logarithmical relationship between the kinematic viscosity of fuels and the mean size of droplets of the spray injected from each injection nozzle del. The mean size of droplet from the throttle nozzle was smaller than that from the pintle nozzle because the rate injection of the throttle was different from that of the pintle nozzle. The droplet size of the hole nozzle was smallest because of the smallest injection port and the highest injection pressure.
