What does OHC mean?

OHC stands for "Overhead Cam," which refers to a type of engine design where the camshaft is located above the cylinder head, directly controlling the opening and closing of the engine's valves. This design can improve engine efficiency and performance by allowing for more precise timing of valve movements. OHC engines can be further categorized into single overhead cam (SOHC) and double overhead cam (DOHC) configurations.
