3.4 燃油系统
fuel system
燃油系统的功用是根据柴油机的工作要求定时、定量、定压地将柴油以雾化的状态按一
定的供油规律喷入气缸内，并使其与空气迅速而良好地混合和燃烧。它的工作情况对柴油机
的动力性和经济性有着重要的影响。柴油机燃油系统由油箱（用户自配）、进、回油管、柴油
滤清器、喷油泵、高压油管、喷油器等组成。
The fuel system works to inject the spray diesel oil with certain quantity at certain time and
pressure according to the fuel supply rules and working requirement of the diesel engine,
thus the diesel oil will mix with the air well rapidly to combust. The working status of the
system attaches much importance to the power and economics of the diesel engine. The fuel
system of the diesel engine consists of fuel tank (equipped by user), fuel inlet/return pipe,
diesel oil filter, fuel injection pump, high pressure fuel pipe and fuel injector.
喷油泵为单列柱塞式，使用时应注意：
The fuel injection pump is of in-line piston type.
