How are intake and exhaust valve clearance and fuel injector height adjusted?
How are intake and exhaust valve clearance and fuel injector height adjusted?
Intake and exhaust valve clearance and fuel injector height are adjusted by means of an adjusting set screw and locknut located at the valve end of the rocker arm. See Figure “Valve and Fuel Injector Rocker Arm Assembly Components” .
How to adjust engine injectors and valves sinocmp?
1. Torque method: The NT (A) 855 engine with a large cam non-stop injector is taken as an example to introduce the torque adjustment method. Look at Table 1 for the technical requirements for the adjustment of the injectors and valves of the NT (A) 855 engine.
How is the injector and the valve interrelated?
The injector controls the fuel entering the cylinder. The valve controls the intake and exhaust valves of the engine. At the same time, the adjustment of the injector and the valve are interrelated in the adjustment sequence and method.
Do you have to adjust the valve after adjusting the injector?
When applying the torque method adjustment, it should be noted that the valve of the same cylinder should be adjusted immediately after adjusting the injector of one cylinder, but it is not allowed to adjust the valve after adjusting the valve. 2.
How to adjust the valve and injector settings?
