How CNG ecu works?
How CNG ecu works?
The Motronic control unit for CNG controls the mixture formation (air mass, injected CNG mass and time of the injection), ignition and exhaust-gas treatment. In bifuel systems, Motronic controls the engine operation with CNG and gasoline. If the tank runs out of CNG, it automatically switches to gasoline operation.
What are the basic sensors required for an engine management system?
These include Throttle Position Sensor (TPS), Mass Air Flow (MAF) sensor, Manifold Air Pressure (MAP) sensor, and Intake Air Temperature (IAT) sensor. By using one or a combination of all four of these sensors, there are four distinct strategies that can be employed to determine engine load.
What kind of engine control unit is Motronic?
Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH (commonly known as Bosch) which combined control of fuel injection and ignition in a single unit.
What was the major change in the Motronic 1.5?
Major change was the use of a MAF instead of AFM in the Motronic 1.5. Was used since 1994 in the Opel Omega B with X20SE engine. (Modified successor of C20NE engine) Major change to the Motronic 1.5.2 was the use of DIS ignition system, knock sensor and EGR valve.
What’s the difference between Motronic 1.1 and 1.3 ECM?
The Motronic 1.1 and 1.3 systems are largely similar, the main improvement being the increased diagnostic capabilities of Motronic 1.3. The 1.3 ECM can store many more detailed fault codes than 1.1, and has a permanent 12-volt feed from the vehicle’s battery which allows it to log intermittent faults in memory across several trips.
What kind of ECU is Bosch Motronic m5.2.1?
BOSCH MOTRONIC M5.2.1 – System Overview This is quite a sophisticated Petrol Engine management system which is manufactured by Bosch. This ECU was one of the first Flash memory based ECU’s with a huge memory the entire code that controls it’s operationally and functionality including its self diagnostic capability.
