How to Adjust the Valves of a Three-Cylinder Engine?

[DeFelix]

Adjustment method for three-cylinder valves: First, rotate the crankshaft to identify the engine's firing order. Then, turn the crankshaft to reach the top dead center of the third cylinder's compression stroke. At this point, the third cylinder is at the compression top dead center, and all other valves are closed. Adjust the intake and exhaust valves of the third cylinder. Finally, rotate the crankshaft 360 degrees to reach the exhaust top dead center of the third cylinder. A three-cylinder engine consists of three cylinders arranged identically within a single engine block, sharing a common crankshaft to output power. Its primary function is to convert chemical energy into mechanical energy. The fundamental principle of a three-cylinder engine involves the conversion of gasoline (or diesel) chemical energy into thermal energy. The combustion and expansion of the air-fuel mixture within the sealed cylinder drive the piston to perform work, thereby transforming thermal energy back into mechanical energy. Its main applications include providing power for traditional internal combustion engine vehicles and new energy hybrid models.
