Overhead valve engine An overhead valve engine (OHV engine), or "pushrod engine", is a reciprocating piston engine whose poppet valves are sited in the cylinder head. An OHV engine's valvetrain operates its valves via a camshaft within the cylinder block, cam followers (or "tappets"), pushrods, and rocker arms.

The OHV layout permits smoother fuel mixture intake, quicker and more complete exhaust. The increased combustion efficiency enables a higher compression ratio to be used. 4 CYCLE OVERHEAD VALVE ENGINES Small Engine Suppliers engine identification decal also provides the applicable warranty code and oil recommendations (diag. 2). Interpretation of Model Number The letter designations in a model number indicate the basic type of engine. OHH Overhead Valve Horizontal OHM Overhead Valve Horizontal MediumFrame OHSK Overhead Valve Horizontal Snow King Camshaft Configurations | HowStuffWorks Double Overhead Cam. A double overhead cam engine has two cams per head.So inline engines have two cams, and V engines have four. Usually, double overhead cams are used on engines with four or more valves per cylinder a single camshaft simply cannot fit enough cam lobes to actuate all of those valves. Animated Engines Four stroke Larger four stroke engines usually include more than one cylinder, have various arrangements for the camshaft (dual, overhead, etc.), sometimes feature fuel injection, turbochargers, multiple valves, etc. None of these enhancements changes the basic operation of the engine. How a 4 Cycle Engine Works | Briggs & Stratton In overhead valve (OHV) engines, the valves are positioned above the piston. The camshaft moves the valves through a tappet, pushrods and rocker arms. 4 cycle OHV engines provide more efficient combustion by allowing the air fuel mixture to spread more evenly throughout the combustion chamber. 8 to 18 HP Cast Iron Four Cycle Engines CAST IRON FOUR CYCLE ENGINES This manual covers the following models: VH80, VH100, HH80, HH100, HH120, OH120 180 Model numbers are located on the engine shroud. ...

Understanding overhead valve engines grounds mag The engine is an overhead valve design if the camshaft is located in the engine block. The VIB design is less expensive to produce and is typically found on lower end engines. System operation The camshaft is located in the engine block on an overhead valve engine. The camshaft uses lifters, push rods and rocker arms to activate its valves. A Critique of the “Flathead” or Side Valve Engine Design It seems that I often refer to the superiority of the overhead valve engine design as compared to the side valve or "flathead" engine design. My day job is as a consulting engineer (although not in the automotive industry) so I have an engineering interest in the technical aspects of automotive design. As a result, I… Overhead camshaft Overhead camshaft, commonly abbreviated to OHC, is a valvetrain configuration which places the camshaft of an internal combustion engine of the reciprocating type within the cylinder heads ("above" the pistons and combustion chambers) and drives the valves or lifters in a more direct manner compared with overhead valves (OHV) and pushrods. Engine Valve Train and Ignition Systems | HowStuffWorks Most modern engines have what are called overhead cams. This means that the camshaft is located above the valves, as shown in Figure 5. The cams on the shaft activate the valves directly or through a very short linkage. Older engines used a camshaft located in the sump near the crankshaft. Why Are 4 Valves Better Than 2? DOHC vs OHV Why are 4 valves per cylinder better than 2 valves per cylinder? Is DOHC better than OHV? 4 valves per cylinder allows for more airflow than 2 valves per cylinder, as there is larger open area ...
