Emission Control System (North America)
32
Federal and state laws establish the levels of
exhaust emissions that may be emitted into
the atmosphere by automobiles. To comply
with these regulations, it is essential that your
De Lorean by inspected and maintained in
accordance withe the scheduled
maintenance. (See Maintenance Schedule
Folder).
To control these emissions the De Lorean
uses the following components:
1. Bosch K-Jetronic continuous injection, fuel
injection system.
2. Oxygen (Lambda) sensor closed loop
system.
3. Three-way catalytic converter.
Notice:
Unleaded gasoline is used to reduce
combustion chamber deposits, and to prevent
lead contamination of the catalyst.
If lead fuel is used the catalytic converter will
lose emission control effectiveness.
Notice:
Damage to the catalytic converter can be
caused if the engine is not performing
correctly. Do not continue to drive your
vehicle if you detect engine misfire, noticeable
loss of performance or other unusual
operation conditions.
CAUTION: Do not park your vehicle over
combustible materials, such as grass or
leaves. They could touch the exhaust system
and ignite.
Oxygen (Lambda Sensor Closed Loop
System)
The Oxygen Sensor Closed Loop System
monitors the exhaust as it leaves the engine
and before it enters the catalytic convertor.
The oxygen sensor signals the electronic
control unit to adjust the volume of fuel being
injected into the combustion chamber.
Notice:
The Lambda Service Warning Light will
illuminate at 30,000 miles (50,000 km)
replaced with a new sensor. Such
replacement is necessary in order to maintain
the correct operation of the emission control
system. The indicator must be reset as part
of the service.
Emission Performance at Altitude
To ensure compliance with the Emission
Regulations at high altitude and maintain
optimum fuel economy and driveability your
vehicle requires adjustment to the engine
settings. A Service Bulletin has been
supplied to your Dealer to enable him to
adjust the engine correctly. Your new
vehicle delivered in a high altitude area will
have been adjusted prior to delivery, and a
label to this effect will be be attached to the
engine settings label in the engine
compartment.If you have permanently
relocated to a high altitude area from a low
altitude area or vice versa your vehicle will
require adjustment to be made to achieve the
exhaust emission control, fuel economy,
and driveability of vehicles originally sold at
this altitude. It is recommended that you take
your De Lorean to your local Dealer and have
these adjustments made.
Note: It is not necessary to perform these
adjustments if you have intend to make only
a temporary visit to a high altitude location.
Vehicle performance will remain adequate for
any such temporary period.
Notice:
Section 203 of the Clean Air Act prohibits any
person to remove or render inoperative any
device specifically installed on the vehicle to
ensure that the vehicle complies with
Emission Control Standards. It is essential
therefore that components to the correct
specification are fitted and specified engine
settings are strictly adhered to.
