D:04:04 Fuel, Emission and Exhaust System permanently into a high altitude area will require label part number 110741 attaching after adjustment, whereas vehicles relocating permanently to a low altitude area will require the original label removing. Note: It is not necessary to perform these adjustments for only, a temporary visit to a high or low altitude area. Vehicle performance will remain adequate for cny such temporary period. LAMBDA CONTROL SYSTEM The De Lorean uses a Lambda control system developed by Bosch. The Lambda system is used in conjunction with the K-Jetronic fuel injection and a three-way catalytic converter to control exhaust emissions. Lambda control, used with a three-way catalytic converter, is capable of reducing the noxious emissions of carbon monoxide (CO), hydrocarbons (CH) and nitrogen oxides (NOx). A requirement for this action, however, is that the air-fuel ratio must be controlled to a high degree of accuracy so that the engine will operate within an "ideal" air-fuel mixture range. LAMBDA CONTROL PRINCIPLE The control principle employed is based on the fact that the Lambda sensor is continuously monitoring the exhaust gas and informing the fuel injection system to modify the mixture for minimum emissions. Acting as a monitoring device, the oxygen sensor in the exhaust pipe provides data on whether the mixture is richer or leaner than the "ideal". The Lambda electronic control unit 'ECU) processes this data and sends a signal to the fuel injection system to cnange the amount of fuel injected into the engine.

Fuel, Emission and Exhaust System D:04:05 SYSTEM OPERATION-OXYGEN SENSOR The oxygen sensor measures the amount of oxygen in the exhaust gases. As the sensor measures the exhaust gas, it produces an electrical signal which informs the Lambda ECU module if the engine is running richer or leaner than the "ideal" air-fuel mixture ratio. Fig. 22 imi The sensor is mounted in the exhaust pipe in a position where it will monitor the exhaust gas from both cylinder banks before it enters the catalytic converter. Fig. 22. OXYGEN SENSOR
