Differences Carburetor and Injection Systems Work

 Differences Carburetor and Injection Systems Work

 

Actual duties and functions of the carburetor and injectors at the same motors that mixes air and fuel in order to accurately complete combustion occurs in the combustion chamber. But the workings of the carburetor and fuel injection that distinguish motorcycle. What are the differences in how the carburetor and injection motor, let us learn together - together.

A. The workings of the fuel mixes with air.
 
    In the system of the carburetor, fuel and air mixing in the combustion chamber caused the vacuum caused by the piston suction step. If the injection system, fuel and air mixing is done by the command of ECM injector that takes into account signals from the sensors are spread throughout the engine and exhaust.

2. At the temperature of the cold engine.

    When the temperature of the engine cold engine requires a richer mixture of gasoline to the engine. In the carburetor system, to enrich the fuel mixture activated choke (choke) for comparison gasoline become rich. For the fuel injection system, a temperature sensor to report the state of the engine temperature is cold to the ECM commands fuel injector to enrich the mixture.

3. At the time of acceleration.

    At the time of acceleration of the motor requires a fuel mixture of about 8:1 AFR quite rich. In the carburetor system assisted by the nozzle accelerator that works add to the supply of fuel to the engine when it comes opened valve gas - arrived. If the injection system throttle position sensor will send a report to the ECM that the throttle opening occurs suddenly and ECM will command the injectors to enrich the fuel mixture.

4. At high rpm

    At high rpm, the system of the carburetor main jet and pilot jet is fully open so as to produce a large force. If the fuel injection system, throttle position sensor and the sensor in the intake manifold vacuum are both sending a signal to the ECM in order to enrich the mix a little gasoline to generate maximum power.
