SOHC engines generally can run at higher speeds than OHV engines, so a smaller SOHC engine can produce as much or more horsepower than a larger OHV engine and often better fuel economy. One In The Garage with CarParts.com EVs and Hybrids SOHC vs. DOHC: What's the Difference and Which Is Better? How Camshafts and Valves Work What are the Different Camshaft Location Classifications? What is an SOHC Engine? What is a DOHC Engine? Which is Better: SOHC or DOHC? SOHC vs. DOHC Fuel Efficiency Three common types of camshaft engines are in popular use today and many are confused about what the differences are between them: OHV. SOHC. DOHC. All camshaft-type engines have three basic components in their heads which actuate the intake and exhaust for each cylinder: camshafts, rocker arms, and valves. The camshaft rotates in time with the This design applies to slower-speed engines. It involves many moving parts and results in sluggish engine response. However, the passenger cars needed refined high-speed engines. So, the engineers replaced this technology with a more sophisticated 'Over Head Camshaft' design mechanism or the OHC. What is OHC? SOHC has many advantages over DOHC, but also DOHC isn't lacking a lot when it comes to the advantages over the SOHC design. That's why, before you consider getting a new car, you should consider DOHC as well. DOHC stands for dual overhead camshaft, which means that there are two camshafts in the cylinder head. Most modern motors fit into one of these categories. SOHC = Single Overhead Camshaft. DOHC = Dual Overhead Camshafts. There's more to evaluate aside from how many camshafts are in each cylinder head. .
