What is motronic control unit?
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 is the main difference between motronic and Jetronic engine?
As far as I can tell, the L-Jet and Motronic systems in the 75/164 (respectively) are very similar; air flap for measuring airflow, throttle position sensor, coolant temperature sensor, rpm, etc. It seems the only difference on the fuel side is the L-Jet is analog and the Motronic is digital.
What is a Bosch ECU?
The electronic engine control unit (ECU) is the central controller and heart of the engine management system. It controls the fuel supply, air management, fuel injection and ignition. The ECU manages all types of powertrain and topologies such as Gasoline, Diesel, CNG, Ethanol and also Hybrid and Fuel Cell system.
What is the Volvo engine management system known as?
VECTRO. 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.
How do I identify my Bosch ECU?
Diesel Bosch ECU Diesel engine control unit are identified by E character at the beginning of name. For example ecu in picture is a EDC16C34.
How much does a ECU cost?
ECU repairs can be very expensive. The part alone can cost between $1,000 and $3,000, depending on the make and model of your vehicle. Fortunately, an ECU can be repaired or reprogrammed in many cases—thus preventing the need to actually replace an ECU.
How do I tell which Bosch ECU I have?
Which year was the e3 injector introduced?
Electronically Controlled Unit Pump As illustrated in Figure 10, a one valve unit pump systems consists of the pump housing with an electrically actuated spill valve, the high pressure injection line and the nozzle holder [113] . Operation is very similar to the single valve unit injector shown in Figure 2.
How is EUP effective stroke controlled?
How is EUP effective stroke controlled? Peak injection pressure values in EUP fueled engines up to 2007 may reach: Technician A states that Bosch EUPs are mounted above and actuated directly by the engine camshaft. Technician B states that duty cycle in an EUP is controlled by the ECM.
How do I know what kind of ECU I have?
To identify your ECU you will need to know its generation, part number and possibly its ROM number. The computer is connected via three connectors that pull out when a plastic clip is pressed. Remove the computer, and with a philips screwdriver remove the metal lid from the top of the computer.
What is ECU part number?
The Manufacturer Identifier and ECU Part Number are either stamped into the plastic case of the ECU or on a sticker on the ECU. The Bin File Serial Number is not visible externally, it is in the bin file inside the ECU.
What is the m-Motronic system?
The M-Motronic system. System overview. M-Motronic combines all the electronic systems for engine control in a single control unit (ECU) which, in turn, governs the actuating systems used to control the spark-ignition engine.
What is a Bosch Motronic ECU?
The Bosch digital Motronic ECUreplaced the older analogue L-Jetronicsystem, to provide more precise control of the engine’s fuellingand ignitiontiming which improves power, fuel economy and emissions. Motronic is the trade name given to a range of digital engine managementsystems developed by Bosch.
Can the Motronic system be chipped?
The Motronic system can be ‘chipped’, which involves replacing the standard EPROM (Erasable Programmable Read Only Memory) chip with one containing a performance enhancing program or ‘map’ for improved driveability, throttle response, mpg, raised rev limit, etc.
What are the components of the Motronic ML1 system?
The components of the Motronic ML1.x systems for the most part remained unchanged during production, although there are some differences in certain situations. The engine control module (ECM) receives information regarding engine speed, crankshaft angle, coolant temperature and throttle position.
