Also, it is easy to service and less expensive. The system has better control compared to a carburetor. A single-point injection for many manufacturers was a revolution to the existing and more complex multi-point fuel injection. A throttle-body injection replaces the carburetor with a couple of fuel injectors in the engine’s air intake manifold. It is the simplest and earliest type of fuel injection. The fuel injection types that you find in other vehicles include the following. Typically, fuel injection in vehicles consists of four different types. As little as 6 volts is needed and anything below that won’t let the engine run. Also, there must be enough voltage in the battery so that it can produce a spark with the ignition coil in place. However, the ATVs that have an electronic fuel injection system need a battery to keep the engine running. Here are some of the ATVs models that come equipped with an electronic fuel injection system. And, the fuel injectors are controlled by the Engine Control Unit. It is then pumped to individual injectors and they are directly inserted into the engine’s manifold. The fuel pump helps the fuel flow out to a fuel injection rail from the tank. An electronic fuel injection system consists of sensors, fuel injectors, fuel pump, and ECU or Engine Control Unit. The system injects fuel into the engine’s cylinder or manifolds directly by using certain electronic components.Īlthough the auto industry is greatly benefited from this technology, it is not common in small engines. However, the introduction of electronic fuel injection or EFI replaces the need for a carburetor. Traditional engines needed a carburetor to mix fuel and air.
