=> The Four Stroke Cycle (4-14).
The engine is started by electric starter motor

7-2. When the engine runs the crankshaft
7-3 drives the camshaft
7-4 via gears. The camshaft opens and closes the inlet and exhaust valves
7-5 and 7-6 via push rods
7-7 in time with the four stroke cycle. The engine has 16 valves, 2 inlet and 2 exhaust valves for each cylinder.
The crankshaft also drives a mechanical fuel injection pump
