This type of camshaft drive was used by the Bearcat 4-Stroke Cycle outboard motor. The bottom bevel gear is attached to the crankshaft and drives the perpendicular shaft. The top bevel gear is attached to the camshaft and is driven by the perpendicular shaft. Which is sometimes called a “Twin-Overhead Cam”.īelow are the gear driven cams of a Cosworth V8.īelow is a cam driven by a perpendicular shaft with bevel gears. The illustration on the right shows a chain driven “Dual-Overhead Cam” (DOHC) In the cylinder block with tappets (sometimes called “lofters”), push rods and rocker arms. The illustration on the left shows an “Overhead Valve” (OHV) engine with a chain driven cam + Over-Head Cam (OHC) vs Overhead Valve (OHV) enginesĪlso written as an “Overhead Cam” engine.Ī camshaft can be driven by a belt as illustrated above or by a timing chain,Ī timing gear set, or a perpendicular shaft with bevel gears as shown below.

How Piston Skirt Length Affects Engine Service Life. While they share very similar basic mechanical components including pistons, connecting rods, crankshafts, valves, etc., they also have their differences, especially in their fuel delivery systems, which may be carbureted or fuel injected. They may be spark ignited like gasoline engines or compression Ignited like Diesel engines. But they can also be fueled by Natural Gas (NG), Compressed Natural Gas (CNG), Liquid Petroleum Gas (LPG) such as Propane and Butane, or heavy fuels such as Bunker Fuel.

Modern internal combustion reciprocating piston engines are most often fueled by Gasoline (commonly called just “Gas”), or Diesel. For External combustion engines including steam engines and internal combustion engines other then reciprocating piston engines such as rotary engines and gas turbines, see our Propulsion Machinery page. This article describes the arrangement of mechanical components in Internal combustion reciprocating piston engines.
