Differences YMJET FI FI with Conventional

spray fuel injection

YMJET-FI is not just injection. This tool is a continuation of the Fuel Injection (FI). The results of the spray is more subtle than the FI. YMJET- FI stands for Fuel Injection Yamaha Mixture Jet, is average he manages mixture of fuel and air. This difference FI due YMJET-pressure fuel pump stronger. Strong spray the homogeneous combustion.
Mixture of fuel and air is better. The trick to YMJET-FI no air by-pass hose or call Yamaha Assist Water Passage. It works under ideal round. Thus, not only the air through the throttle body. At low engine speed, air is supplied through the by-pass hose. This hose is integrated directly on the intake manifold, the intake hole injectors are after. Suitable for automatic fuel needs from the beginning to work.

ISC on YMJET FI

YMJET-FI throttle body is different from the FI system Vixion and Jupiter Z1, there are two butterfly valves (butterfly) or so-called coins. Both of these coins are not the same workings. In the second round coin shut the engine idling. Supplied air by-pass earlier, when the rotation is increased then only the first coins were opened, the ride the second round of the butterfly will open, so storied.
YMJET-FI on automatic motor, because the automatic air supply requires denser at lap down. Has no automatic multilevel reduction, must be provided sufficient fuel at low rotation. On the other hand the fuel efficiency were forced to be more efficient, because of the automatic reduction. A by-pass air was manipulated in order to have the available volume continuously. Does not exist in Vixion and Z1, but the injectors and fuel pump systems together, so it is equally smooth.
