Что такое система sohc двигатель

What is the difference between OHV, OHC, SOHC and DOHC engines?

The main difference is in the placement of the camshaft. OHV means Over Head Valve. Although almost all modern car engines have valves placed in the cylinder head, the term OHV is used to describe a pushrod engine, with the camshaft placed in the cylinder block. OHC stands for Over Head Cam, or the camshaft is installed in the cylinder head. SOHC means Single Overhead Cam, while DOHC means Double Overhead Cam.

Which one is better? It’s always a heated argument. Muscle car fans will swear by an old-school pushrod, while younger car enthusiasts will say that nothing beats the twin-cam (DOHC). Each design has its pluses and minuses. Let’s start with the good old Pushrod:
