FUEL INJECTION-GENERAL DESCRIPTION
SYSTEM DESCRIPTION
The De Lorean is equipped with the Bosch K-Jetronic fuel injection system. This form of fuel induction by
means of manifold injection permits the optimum adaptation of the air-fuel mixture to every operating phase
of the engine. The K-Jetronic system ensures a lower pollutant level in the exhaust gas,
high
performance
and increased fuel economy.
The K-Jetronic is a mechanical continuous fuel injection system which does not require any form of drive
mechanism. An electric fuel pump mounted inside the tank provides fuel at
a
constant pressure to the mixture
control unit. The control unit consists of an air flow sensor which measures the flow of air entering the
engine, and a fuel distributor which is mechanically operated by the air flow sensor. The fuel distributor
provides the injection valves with the correct amount of
fuel.
The fuel is injected into the inlet manifold
immediately upstream of the intake valve. Injection takes place continuously, that is, without regard to the
position of the intake valve. During the intake valve closed phase, the fuel is stored
in
the intake tubes of
the manifold.
