What is the difference between electronic fuel injection and carburetor in motorcycles?
1 Answers
The differences between electronic fuel injection and carburetor in motorcycles are as follows: 1. Working principle: The carburetor operates passively, while electronic fuel injection works actively. The carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the engine's operation, utilizing the kinetic energy of the incoming airflow to atomize the gasoline. Its working method is relatively passive and cannot actively control the process. In contrast, electronic fuel injection can regulate the fuel supply, actively increasing or decreasing it, making the working method more controllable. 2. Fuel consumption: Electronic fuel injection is more fuel-efficient than the carburetor. The carburetor supplies fuel to the engine mechanically, and the relationship between fuel supply and engine speed or throttle opening can only be linear, making it impossible to ensure the ideal air-fuel ratio under all working conditions and environments. The carburetor cannot adapt to changes in engine state, leading to increased fuel consumption. In electronic fuel injection, the dedicated software in the microcomputer can intelligently control the fuel supply and ignition in real-time, providing precise fuel delivery. This ensures that the air-fuel ratio and ignition timing can always be optimized under any working condition or environment, thereby reducing fuel consumption and improving overall performance.
