Is the Jog i compliant with China III standard equipped with electronic fuel injection?
1 Answers
Yamaha Jog i scooter adopts a closed-loop electronic fuel injection system. According to relevant environmental protection technical requirements, motorcycles meeting China III standard and subsequent standards must employ closed-loop electronic fuel injection technology. Principle of electronic fuel injection system: The Electronic Fuel Injection (EFI) system uses the Electronic Control Unit (ECU) as its control center. Various sensors installed on the engine measure different operating parameters, and based on pre-programmed control algorithms in the ECU, precisely control the fuel injectors' fuel delivery quantity. This ensures the engine obtains the optimal air-fuel ratio combustible mixture under various operating conditions. The electronically controlled fuel injection systems used in different vehicles often exhibit significant structural differences and possess distinct characteristics in control principles and operational processes. Operating conditions of electronic fuel injection system: The cylinder block, cylinder head, crank-connecting rod mechanism, valve train, intake and exhaust systems, fuel supply system, and electronic control system work in coordination to directly complete the working cycle. Although the lubrication system and cooling system don't directly participate in the working cycle, they are indispensable for long-term normal operation. The starting device provides initial conditions for transitioning from static to dynamic state. During usage, their working conditions must be given sufficient attention, as failure to maintain normal operation cannot be guaranteed and may even cause severe damage to components.
