When working with cars you might wonder how does sequential fuel injection work? When cars first hit the market, they lacked a precision device to inject gas and air in the right amounts each time. The fuel injection device solved this problem and produce fewer emission while increasing gas mileage. To get an idea of how this ingenious device works, an explanation of other type of fuel injection is necessary.
- Single Port versus Multi Port injection. A Single port injection takes gasoline into a central area and propels it with air into a the engine. The single port injection process occurred all at once and combined the actions of a carburetor and injection. As single port is still used, multi port has gained popularity, due to its efficency in devliering gasoline to the engine. Multi port has an injector for each of the cylinders available in an automotive engine. The injector shoot gasoline directs through the values into the combustion chamber. The injectors are powered by two circuits for the entire unit. Each has its own advantages and limitations, but all work on the same principle: to get your car moving.
- Sequential Fuel Injection. Sequential fuel injection works similarly to multi port injection, in that there is on injector for each cylinder. The difference lies in the number of firing circuits. As stated before, multi port does not have one firing circuit per injector, but two for the whole system. In sequential fuel injection each injector has a firing circuit to give accurate and precious amounts of fuel and air each time.
The advent of fuel injection has completely revamped the car industry. With this device, cars can accurately use the correct amounts of air and gasoline to power their engines. To determine the type of your fuel injector, ask your dealer.
