What is Motronic engine management system?
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.
How does KE Jetronic work?
KE-Jetronic (1985–1993) Instead of injecting fuel into the intake, this injector allows fuel to bypass the fuel distributor, which varies the fuel pressure supplied to the mechanical injection components based on several inputs (engine speed, air pressure, coolant temperature, throttle position, lambda etc.)
What is the Volvo engine management system known as?
Volvo electronic engine management. vehicle control unit (VCU) a vehicle management mod ule on the older J1587/1708 bus using the MID 144 address on the chassis data bus; used by some OEMs to optimize powertrain and chassis operations.
What cars use Jetronic?
K-Jetronic debuted in the 1973.5 Porsche 911T in January 1973, and was later installed into a number of Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Nissan, Renault, Volvo, Saab, TVR and Ford automobiles.
What is the difference between D Jetronic and L Jetronic?
L-Jetronic used custom-designed integrated circuits, resulting in a simpler and more reliable engine control unit (ECU) than the D-Jetronic’s. L-Jetronic was used heavily in 1980s-era European cars, as well as BMW K-Series motorcycles.
How do you adjust K-Jetronic fuel injection?
For early model cars using the K-jet (mechanical fuel injection) system, mixture adjustment is quite simple. A 3mm allen wrench is necessary to access the adjusting screw. Turning this screw to the right richens the mixture while turning it left leans it.
What are the three components for the Engine Management System?
EMS stands for Engine Management System, consisting of a wide range of electronic and electrical components such as sensors, relays, actuators, and an Engine Control Unit.
What are the five Engine Management System components?
The EMS is comprised of sensors for intake air and coolant temperature, turbo boost and intake manifold absolute pressure (MAP), throttle position (TPS), engine rpm and position, and exhaust oxygen sensors (UEGO or HEGO).
What is the difference between K-Jetronic and KE Jetronic?
KE-Jetronic (1985–1993) The system is based on the K-Jetronic mechanical system, with the addition of an electro-hydraulic actuator, essentially a fuel injector inline with the fuel return.
How does K Jetronic work?
An air enters to the air filter, then it enters into the engine cylinders through the air flow sensor and throttle valve. Therefore, the rotary-type fuel pump with electric drive supplies fuel from the tank. The fuel enters to the fuel accumulator through the filter.
What are the sensors used in engine management system?
Sensors for Engine Management
- Mass Airflow Sensors.
- Wheel Speed Sensors.
- Camshaft Sensors.
- Crankshaft Sensors.
- Knock Sensors.
- Pressure Sensors.
- Oxygen Sensors.
- Eccentric Shaft Sensors.
