How to Adjust Valves on a Four-Cylinder Engine?

[DelIris]

Here are the methods for adjusting valves on a four-cylinder engine: 1. Cylinder-by-Cylinder Adjustment Method: According to the firing order of the cylinders, determine when a piston is at the top dead center of the compression stroke, then adjust the intake and exhaust valve clearances for that cylinder. After adjustment, rotate the crankshaft and proceed to adjust the valve clearances of the other cylinders step by step using this method. 2. There are four models: L3, L4, L5, and L6. The advantages of this engine layout include compact size, high stability, good low-speed torque characteristics, and lower fuel consumption, which means lower manufacturing costs. 3. Engines with an inline cylinder layout are relatively compact in size, allowing for more flexible arrangements. They are also convenient for installing superchargers and similar devices. The main disadvantage is that the engine's power output is relatively low, making it unsuitable for models with more than six cylinders.
