Chainsaw engines are traditionally either a two-stroke single-cylinder gasoline (petrol) internal combustion engine (usually with a cylinder volume of 30 to 120 cm 3) or an electric motor driven by a battery or electric power cord. In a petrol chainsaw, fuel is generally supplied to the engine by a carburetor at the intake.
Larger gasoline engines used in automobiles have mostly moved to fuel injection systems (see Gasoline Direct Injection). Diesel engines have always used fuel injection system because the timing of the injection initiates and controls the combustion. Autogas engines use either fuel injection systems or open- or closed-loop carburetors.
Some others work by introducing an additional fuel route to the constant depression chamber. Chokes were nearly universal in automobiles until fuel injection began to supplant carburetors. Choke valves are still common in other internal-combustion engines, including most small portable engines, motorcycles , small propeller-driven airplanes ...
A floating inlet valve regulates the fuel entering the float chamber, assuring a constant level. In some small engines that may instead of a float chamber just use a fuel tank close below the carburetor and use the fuel suction to supply the fuel. Unlike in a fuel injected engine, the fuel system in a carbureted engine is not pressurized.
Fuel line feeding the auxiliary power unit of an Airbus A340.. A fuel line is a hose or pipe used to transfer fuel from one point in a vehicle to another. The United States Environmental Protection Agency defines a fuel line as "all hoses or tubing designed to contain liquid fuel or fuel vapor.
Most chainsaw safety features are focused on the kickback problem, and seek to either avoid it (chain and bar design), or to reduce the risk of injury should it occur (chain brakes). In addition to the safety features built into the chainsaw, operators should also wear specific chainsaw safety clothing .

The fuel being burnt in the lean charge is therefore not 'knock' or octane restricted. This type of stratification therefore can utilise a wide variety of fuels; the specific energy output being dependent only on the calorific value of the fuel. A relatively rich air/fuel mixture is directed to the spark-plug using multi-hole injectors.
