How to adjust the valve of diesel engine 12V 135?

There are two methods to adjust the valve of diesel engine 12V 135: cylinder by cylinder adjustment method can adjust the gap between the intake valve and the exhaust valve of a cylinder after determining the compression top dead center position of the piston according to the cylinder ignition sequence; After adjustment, turn the crankshaft and gradually adjust the valve clearance of other cylinders according to this method. Turn the crankshaft twice, so that the piston of the first cylinder is at the compression top dead center, and the flywheel mark is aligned with the inspection hole. At this time, the valves of 1, 2, 4, 5, 8 and 9 can be adjusted (referring to the sequence of engine valves from front to back); Then turn the crankshaft once, so that the six-cylinder piston is at the top dead center of the compression stroke, and then adjust 3, 6, 7, 10 "plus two valves (i.e. 1 1, 12), which is actually memory adjustment. When adjusting, while tightening the adjusting screw, insert the thickness gauge between the valve stem end and the rocker arm to pull it. It is advisable to feel slight resistance, and check it again until it is suitable. The cylinder-by-cylinder method requires the crank to rotate the crankshaft more times, and the inspection and adjustment time is longer. However, for the seriously worn engine, the cylinder-by-cylinder method is more accurate to check and adjust the valve clearance. Adjusting the valve clearance twice saves time and effort, but it is difficult for maintenance personnel to remember the different adjustable valve serial numbers of different models, which is more complicated. Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine. Throttle four-stroke gasoline engines are generally like this. Throttle is one of the most important components in EFI automobile engine system. Its upper part is the air cleaner grille, and the lower part is the engine body, which is the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and powerful. Whether the throttle should be removed for cleaning is also the focus of discussion among car owners.
