ENGINE - Fuel System
-
Normally, the negative pressure in the intake manifold
acts upon the fuel pressure regulator to maintain the
fuel pressure at a constant level with regard to the
pressure inside the intake manifold, causing the amount
of fuel injected to be controlled in proportion to the
injector drive time. However, if the engine is started
while the engine coolant temperature and the intake air
temperature are high, the engine control unit makes
FUEL TANK
The electric fuel pump, in-tank filter and fuel gauge unit
are built into the fuel tank.
The fuel tank has the following features.
• Baffle plates are placed inside the fuel tank to
prevent abnormal noise due to fuel movement.
• There is a reseve cup inside the fuel tank for

current flow to the fuel pressure control valve to activate
the fuel pressure regulator by means of atmospheric
pressure.
Because of this, the generation of fuel vapour due to
the high fuel pressure and high temperature is
avoided, and the idling stability immediately after re-
starting the engine at high temperatures is main-
tained.

gauge unit and fuel pump in one unit is adopted.
• A drain plug is standard-equipped on all models.
