The horizontal petrol engine has a cylinder that runs horizontally with the ground. Other engines, such as typical in-line four-cylinder and six-cylinder models, run in a vertical straight line, with pistons running up and down as the engine rotates.

The key to the operation of a high-performance horizontal engine is its use of a flat crankshaft. The flat crankshaft makes the four-cylinder engine operate like a large two-cylinder engine, with the two pistons firing against each other. It is a bit rough when idle, but the power output is very stable. The problem in many air-cooled horizontal engine designs is that the rear cylinder is blocked by the front cylinder, which causes the rear cylinder to overheat.

Cars are not the only vehicles with horizontal engines. Many airplanes, including airplanes and helicopters, have adopted engine designs. The low profile of the horizontal power plant allows greater survivability around the engine. The flat profile of the engine also helps it form smooth lines within the wing structure. This helps aerodynamics and aesthetics. Many steamboats, including those operating in the Florida Everglades, rely on horizontal air-cooled engines to provide power.

Generally, in modern applications, the term gasoline engine refers to a heavy-duty industrial engine that can continuously run at full load, with an annual operating time of up to 8,760 hours, which is different from the lightweight, high speed and high speed of gasoline car engines. It usually runs for no more than 4,000 hours in the entire life cycle. Typical power ranges from 10 kW (13 hp) to 4 MW (5,364 hp).
