How to Adjust Valve Clearance in a Four-Cylinder Engine?
1 Answers
Four-cylinder engine valve clearance adjustment method is: 1. Divide the number of cylinders into two equal parts, using the center as the symmetry axis; 2. Two people cooperate, with one person rotating the crankshaft; 3. Adjust the valve clearance of a cylinder on the right side of the symmetry axis, paying attention to the intake valve of the corresponding cylinder on the left side of the symmetry axis; 4. Slightly move the valve to adjust the valve clearance of this cylinder on the right side. The hazards of excessive valve clearance are: 1. Reducing the opening degree of the intake valve and shortening the opening time, leading to insufficient air intake and a decrease in engine power; 2. Causing poor exhaust, resulting in increased exhaust gas in the combustion chamber. The valve consists of a valve head and stem, and its function is to input air into the engine and expel the exhaust gases after combustion.
