【Abstract】 In this paper, the authors investigated effects of the zerospray-angle nozzle and other pintle type nozzles (valve guide diamefer: φ5mm φ6mm) on fuel economy of the swirl-combustion-chamber diesel engines, moreover the developing process of the fuel spray injected from these nozzles was measured by using the high speed photography, the injection rate out of these nozzles was measured by using the bosch-lonq-pipe method, thereby the thorough experimental investigation and analysis were carried out, and the proposals for improvement of the pintle type nozzle and fuel coonomy of the diesel engine were offered更多还原
