Twin fuel injection pumps with pressure regulators have been adopted to obtain a high fuel pressure
2
of 7 MPa (71 kg/cm
, 1,015 psi).
The fuel injection pressure is detected by the fuel pressure sensor installed on the fuel rail. Protec-
tors have been incorporated on the fuel pressure sensor to reduce vibrations conducting to the sen-
sor.
High-pressure fuel injection obtains a better air-fuel mixture due to finer atomization.
CAUTION:
Do not disassemble the fuel injection pumps. The proper facilities and special service tools
are required to reassemble them.
