Four-stroke cycle used in gasoline/petrol engines: intake (1), compression (2), power (3), and exhaust (4). The right blue side is the intake port and the left brown side is the exhaust port.
Stihl manufactures a hybrid four stroke engine trimmer that still requires oil to be pre-mixed into the fuel. [citation needed] Battery-powered string trimmers offer cleaner alternatives to consumers by producing zero emissions, being more efficient, and eliminating risks of spilled gasoline. [7]
The four-stroke engine is more efficient when running at full throttle, while the opposite is the case for the two-stroke engine. When a small car under heavy load runs at half speed, the engine automatically switches to the two-cycle mode, which is then more efficient. The research on this showed a 27% reduction in fuel consumption. [8] [9]

The expansion ratio of this engine was much more effective than that of the 1860 Lenoir engine and gave the engine its superior efficiency. The Lenoir engine was an engine that burned fuel without first trying to compress the fuel/mixture. The Otto/Langen atmospheric engine ran at 12% efficiency and produced .5 hp (0.37 kW; 0.51 PS) at 80
The first person to build a working four-stroke engine, a stationary engine using a coal gas-air mixture for fuel (a gas engine), was German engineer Nicolaus Otto. [4] This is why the four-stroke principle today is commonly known as the Otto cycle and four-stroke engines using spark plugs often are called Otto engines.
