When the motor activates the impeller there is a difference in the pressure between the front part of the paddles
and the rear part with the grooves, seen from an angular direction, because of the friction of the fluid. This pro-
cess is continuous, thereby causing the increase in the fuel pressure. The pressurised fuel therefore leaves the
pump chamber and is discharged towards the section of the motor and the control valve.
Air intake injection system
COMPONENTS
Fuel pump
The electric fuel pump that is situated inside the fuel tank consists of an electric motor, of the rotor, impeller, con-
trol valve and pressure release valve.
The ECU controls the ON/OFF condition as described in the section FUEL PUMP CONTROL SYSTEM.
When electrical energy is supplied to the pump, the motor switches on and the impeller activates. This causes a
difference in pressure on both sides of the impeller because the paddles of the impeller are grooved. The fuel is
therefore sucked towards the output passage. The pump possesses a control valve to maintain a certain pres-
sure in the fuel feed tube even when the pump is stopped and the pressure release valve opens to send fuel back
to the tank when the pressure of the feed fuel increases to 4.5 - 6.5 kg/cm2.
Absorbed current: 6 – 6.5A at a 13.5V voltage input
