C small engine this article july 2011 rotary lawn mower with a vertical shaft engine a small engine is the general term for a wide range of small displacement low powered internal combustion engines used to power lawn mowers generators concrete mixers and many other machines that require independent power sources tecumseh engine dating. Before the invention of the recoil starter a notched pulley was attached to the engine s flywheel the operator would manually wind a rope around the pulley then jerk the rope to rotate the engine so that it would start. The most common are four stroke air cooled single cylinder engines running on either petrol or diesel. Most small engines have a governor to regulate and maintain the engine speed as constantly as possible despite changing load tecumseh engine dating. Alternatively the tank may be placed below a carburettor which uses engine vacuum or crankcase pressure pulsations to lift fuel into the carburetor. However a self retracting rope pull mechanism called a recoil starter is the predominant method of starting small engines it does not require a battery to power a starter motor nor an alternator to keep a battery charged.

Generally the nominal throttle control does not directly control the opening of the carburetor throttle but rather increases or decreases spring tension on the governor which in turn regulates the engine speed higher or lower. Contents power range edit the engines which may be of two or four stroke design are small in both physical dimensions and power output relative to larger automobile engines.
