目前,国内工程机械发动机普遍采用涡轮增压及中冷技术,高技术含量的电喷技术还没有被广泛应用,发动机性能没有质的提高,影响了我国工程机械行业的整体水平。在工程机械中采用电喷柴油发动机可以达到环保节能的效果,并获得较高的动力经济性能。虽然,一些挖掘机制造商推出了配套电喷发动机的挖掘机,并实现销售,但是,电喷发动机在国内仍然没有形成规模化市场,尤其是难以接受电喷发动机对油品质量的严苛要求。那么,电喷发动机在国内难以被用户接受,是否仅仅是油品的原因?大家怎么看?
At present, the turbocharger and intercooler technology are widely used in domestic construction machinery engines. The high-tech EFI technology has not been widely used yet, and the engine performance is not improved qualitatively, affecting the overall level of China’s construction machinery industry. The use of EFI diesel engine in construction machinery can achieve the effect of environmental protection and energy saving and obtain higher dynamic economy performance. Although some excavator manufacturers have introduced and commercialized excavators equipped with EFI engines, there is still no large-scale market for EFI engines in China. In particular, it is hard to accept the stringent requirements of EFI engines for the quality of oil products . Well, EFI engine in the country is difficult to be accepted by users, whether it is only the reason for oil? How do you think?
