Engine timing (detailed explanation of engine timing adjustment skills and Trade data for risk scoring modelsmethods) Engine timing adjustment is an important part of ensuring the normal operation of the engine. If the timing of the engine is improperly adjusted, it may lead to excessive fuel consumption, unstable engine operation and increased fuel consumption and other problems. This article will introduce you in detail the skills and methods of engine timing adjustment. I. What is engine timing? Engine timing refers to the crankshaft in the engine in a specific working state., the state of motion of the camshaft and piston is consistent with certain specific points in time, which is the basis for the reliable operation of the engine. The timing of the engine mainly affects the control of ignition and valve, which can affect the performance of the engine's power, economy, emission, noise and other performance indicators. II. Engine time adjustment method 1. Check and adjust the camshaft to check the synchronization status of the camshaft and the crankshaft. Usually, tools are used to rotate the crankshaft to a specific position (such as TDC). Then check the synchronization of the camshaft. In this case, the cam of the camshaft should be completely opposite to the state of the valve, that is, 0° angle or 180°. If it is inconsistent, adjust the synchronization of the camshaft. 2. Adjust the spark plug time to adjust the timing of the engine by adjusting the spark plug time. Usually, high distillation is used.Fuel, after turning the engine to a specific position, use the adjustment instrument to measure the time of the spark plug and adjust the timing according to the data. 3. Check the valve torque. On some engines based on over-pressure combustion technology, the torque of the valve is relatively sensitive. If the torque of the valve is uneven, it will affect the sealing state of the valve and the cylinder. An instrument to check the valve torque can be used to check the valve torque at a specific angle and adjust the valve torque according to the data. 4. In some engines, the adjustment lever can be adjusted at a specific crankshaft angle to adjust the timing of the engine. Through the adjustment lever, the position relationship of the chain, gears, etc. inside the crankshaft can be adjusted to achieve the timing adjustment of the engine. III. Engine timing adjustment skills 1. When adjusting the engine timing, it is necessary to understand the advantages and disadvantages of various adjustment methods first.Different methods are applicable to different types of engines. When adjusting, you need to choose the most suitable adjustment method according to the actual situation of the engine. 2. For older engines, it is necessary to flexibly master the adjustment method in combination with the actual situation. The adjustment methods of some traditional engines are usually relatively complex. It is necessary to pay attention to relevant details and appropriate adjustment parameters to ensure the accuracy of engine time. 3. For the new engine, more advanced adjustment methods need to be adopted. Some new engines generally adopt electronic ignition. This adjustment method is different from the traditional spark plug time adjustment method, and the corresponding adjustment method needs to be used according to the specific situation. IV. Summarize that the timing adjustment of the engine is a key part of maintaining the normal operation of the engine, and it is necessary to adopt the correct adjustment methods and methods. We oftenThe adjustment methods shown include: checking and adjusting the camshaft, adjusting the spark plug time, checking the valve torque and adjusting the lever, etc. When adjusting, you need to master relevant skills and choose a suitable adjustment method according to the specific situation in practice.
