Are all China IV motorcycles equipped with electronic fuel injection?
2 Answers
"China IV" is a national environmental emission standard, and it does not necessarily mean electronic fuel injection; it can also refer to carburetors. The electronic fuel injection system is controlled by a computer, which allows for more precise delivery of the air-fuel mixture into the combustion chamber compared to carburetors, but it is also used in "China III" motorcycles. Introduction to Electronic Fuel Injection: Electronic fuel injection is a type of engine that differs significantly from carbureted engines, and the operating methods also vary considerably. FAI Electronic Fuel Injection System: The Free Armature Injection (FAI) system is an independent and complete technical system developed by Feiya Electronics Co., Ltd. It includes invention of working principles, technological breakthroughs, and theoretical breakthroughs. The FAI technical system provides a platform for the upgrade of small engines, enabling comprehensive improvements in performance, fuel consumption, and emission pollution. The emergence of the FAI technical system marks a milestone in the development history of small engines.
Speaking of China IV motorcycles, I believe most of them have adopted electronic fuel injection systems. The China IV emission standards raised environmental requirements, forcing manufacturers to optimize fuel injection control to reduce exhaust emissions. Electronic fuel injection systems can precisely regulate the fuel amount, thus performing better during cold starts and acceleration. However, this doesn’t mean all China IV models are fuel-injected—some low-end or older models may comply by modifying carburetors, though fuel injection has now become the mainstream in the market. From my experience, fuel-injected bikes offer many benefits: about 10% better fuel efficiency, quicker starts, and stable performance especially in sub-zero temperatures. However, repairs can be more troublesome, requiring professional diagnostics. Overall, the China IV transition is a major step forward, helping reduce urban smog issues. I recommend beginners prioritize fuel-injected models when choosing a bike—they’re more cost-effective and reliable in the long run.
