Pronunciation: [sˈə͡ʊk] (IPA) 
The acronym "SOHC" stands for Single Overhead Camshaft. The word is spelled /sɪŋɡəl ˈəʊvəhɛd ˈkæmʃæft/ in IPA phonetic transcription. The "S" in "SOHC" represents "single," while "OHC" denotes "overhead camshaft." The word "single" is pronounced with a short "i" sound and a hard "g," while "overhead" is pronounced with a schwa sound and the "h" is silent. "Camshaft" is pronounced with a short "a" sound and "sh" sound at the end.
SOHC, also known as Single Overhead Camshaft, refers to a type of engine design utilized in internal combustion engines. It is an acronym that stands for Single Overhead Camshaft, which indicates that the engine has only one camshaft located above the cylinder head.
In an SOHC engine, the camshaft is responsible for actuating the intake and exhaust valves of the engine. It is positioned within the cylinder head and is driven by the crankshaft through various mechanisms such as gears, belts, or chains. The camshaft's lobes, which are eccentrically shaped, push against the valve lifters or directly operate the valves to open and close them at the appropriate times.
Compared to other engine designs, such as DOHC (Dual Overhead Camshaft), SOHC engines tend to be simpler and more cost-effective to manufacture. However, they often have limitations in terms of performance and efficiency due to the camshaft's single design. This design typically results in fewer valves per cylinder and less precise control of valve timing.
SOHC engines are commonly found in a range of vehicles, from compact cars to larger sedans, and even some light-duty trucks. While they may not offer the same level of performance and sophistication as DOHC engines, they still provide reliable power and adequate performance for most everyday driving needs.
In summary, SOHC refers to the engine design where a single camshaft is positioned above the cylinder head and controls the opening and closing of the intake and exhaust valves. It is a simpler and more cost-effective design, commonly found in various vehicles.
