Cylinder Head Assembly: Description and Operation

Cylinder head
The engine has two cylinder heads, called the rear cylinder head (cylinders 1-3-5) and the front cylinder head (cylinders 2-4-6).
Each cylinder head is precision cast in light alloy and fitted to the cylinder block with bolts. The combustion chambers are hemispherical with four valves per cylinder and the spark plugs in the center. This improves the flow of gases in the cylinders and also ensures effective combustion of the fuel-air mixture, which makes for a high-efficiency power unit.
The valve springs for the front cylinder head's exhaust camshaft are of "double spring type" while other valve springs are of 'single spring type".
