Fuel Injection Advance Angle of 50kw Yuchai Generator

The Dingbo series 50kw Yuchai generator inherits the excellent characteristics of Yuchai machines, with the advantages of good acceleration performance, high reliability, durability, and economic fuel efficiency. So how can we confirm its fuel injection advance angle on the machine?

The fuel supply advance angle of the 50kw Yuchai diesel generator inline piston injection pump diesel engine is an important parameter of the fuel system. However, in many cases, the lack of a specific value for the fuel supply advance angle brings a lot of trouble to the maintenance and adjustment of the diesel engine. For diesel engines without specific parameters for fuel injection advance angle, before major repairs or fuel injection system repairs, the fuel injection advance angle of the diesel generator can be tested in advance. The specific approach is:

1. On the premise of ensuring that the transmission system of the diesel generator fuel injection pump is not damaged, remove the high-pressure oil pipe of the first cylinder (if there is an oil quantity observation device, install it). If there is a top dead center mark and pointer on the flywheel or drive belt wheel of the diesel engine, you can slowly turn the crankshaft of the diesel generator in a clockwise direction. At this time, pay attention to observing the fuel supply situation of the first cylinder. When there is an indication of an increase in the oil level inside the device, immediately stop rotating the crankshaft and check the distance quotient (angle or arc length) between the pointer of the flywheel or drive belt pulley and the top dead center mark, which is the fuel injection advance angle of the diesel generator (although it may not be very accurate, it can be referred to).

2. The calculation method for converting arc length to angle:

α= 3.14LR/360 (°) (L is the arc length, mm; R is the radius of the drive pulley, mm).

3. Some (imported) diesel engines have fuel injection advance angle values on their labels, please pay attention to them.

4. If the driving device of the fuel injection pump is damaged or experiences significant displacement, the above method cannot be used for confirmation.
