Abstract: In the investigation on the combusting performance of tea seed oil on the S195-Diesel Engine, the exhaust experiments of degreased tea seed oil was conducted to measure its exhaust value, such as smoke, HC, NO_x, and CO. Besides, the microscopic structure of carbon particle of combustion gas was determined by the electronic scanning microscope. The results showed that it is feasible to combust degreased tea seed oil, or mixture of tea seed oil with diesel oil on the Diesel Engine with no modification of its essential structure because of its good combusting performance, less exhaust and carbon deposit.

Key words: diesel engine, tea seed oil, combustion exhaust gas
