overhead camshaft engine

OHC engines are characterized by a special type of valve timing system in which the valve drive shaft is located directly in the cylinder head. Most modern cars use OHC engines. It is easy to operate, driven by a chain or an elastic belt with a toothed wheel.

SOHC reached its peak of popularity

SOHC engines were most popular in the XNUMXs. They are less emergency, stronger than DOHC, but they did not revolutionize the market. The advantage of the SOHC system is the absence of timing elements such as pushrods and locking levers. Thanks to this, the engine is agile and provides very good speed.

DOHC is the perfect solution?

The DOHC engine is characterized by having as many as two camshafts and is commonly used around the globe to refer to piston engines in which the head has two camshafts. Engines with this type of valve timing are by far the most efficient and recommended. They provide much more power with less fuel consumption. 

The DOHC engine is efficient and economical, which is why it is so popular with car manufacturers.
