DCP-FI System

1. Introductions

Pursuing the greatest precision, the DCP-FI system maintains an incomparable position among its competitors. By accurately controlling the air-fuel ratio and ignition timing, it uses 5-12% less fuel compared with conventional carburetor. Thanks to the cutting-edge DCP-FI technology, the engine can provide quick response starts, comprehensive protection and cleaner emission. The DCP-FI system helps provide riders with a smooth and satisfying on-road experience.

How It Works

DCP-FI is the newest motorcycle fuel injection system developed by Mikuni Corporation, which has obtained 12 patents in Japan for this invention. DCP-FI l h thng phun nhin liu xe my mi nht c pht trin bi Cng ty Mikuni, thu c 12 bng sng ch ti Nht Bn v pht minh ny

The DCP-FI system contains seven types of electronic sensors, including intake air pressure sensor, intake air temperature sensor, throttle position sensor, oxygen sensor, crankshaft position sensor and coolant temperature sensor, which enable a series of ECU calculations based on the operating state of the motorcycle and the behavior of the rider. With precise control of the air-fuel ratio and ignition timing, it helps to achieve greater engine power, higher combustion efficiency, less fuel consumption and cleaner emission.

3 Advantages of the DCP-FI System over EFI Systems: (Nhng li th ca h thng DCP-FI so vi h thng EFI)

Low Failure Rate: (mc sai xt thp): Intelligent Integration (s tch hp thng minh bn trong) The discharge pump of the DCP-FI system integrates the functions of various components including fuel pump, pressure regulator and injector, thus having a lower failure rate. And its power consumption is much lower than that of the EFI systems.

II. High Safety The unique gravitational fuel delivery system eliminates the risk of accidental leakage of massive high pressure fuel.

III. Reliable Start-up With a super-capacitor in the start-up circuit, you can easily start the motorcycle by kicking the starter even if the motorcycle is left turned off for a long time with insufficient battery power.
