Motronic is the trade name given to a range of digital engine control units developed by Robert Bosch GmbH commonly known electronicaa Bosch which combined control of fuel injection and ignition in a single unit. By controlling both major systems in a single unit, many aspects of the engine’s characteristics such as power, fuel economy, drivability, and emissions can be improved. Often known as “Motronic basic”, Motronic ML1. These early Motronic systems integrated the spark timing element with then-existing Jetronic fuel injection technology.

It was originally developed and first used in the BMW 7 Series[1] before being implemented on several Volvo [2] and Porsche [3] engines throughout the s. The components of the Motronic ML1. The engine control module ECM receives information regarding engine speed, crankshaft angle, coolant temperature and throttle position. An air flow meter also measures the volume of air entering the induction system.

If the engine is naturally aspiratedan air temperature sensor is located in the air flow meter motrlnic work out the air mass. However, if the engine is turbochargedan additional charge air temperature sensor is used to monitor the temperature of the inducted air after it has passed through the turbocharger and elextronicain order to accurately and dynamically calculate the overall air mass. The systems have the option for a lambda sensor, enabling their use with catalytic converter-equipped vehicles.

This feedback system allows the system analyse exhaust emissions so that fuel and spark can be continually optimised to minimise emissions. Also present is adaptive circuitry, which adjusts for changes in an engine’s characteristics over time. Some PSA ineccion also include a knock sensor for ignition timing adjustment, [4] perhaps this was achieved using an external Knock Control Regulator.


The Motronic units have 2 injection outputs, and the injectors are arranged in 2 “banks” which fire once every two engine revolutions. In an example 4-cylinder engine, one output controls the injectors for cylinders 1 and 3, and the other controls 2 and 4.

The system uses a “cylinder ID” sensor mounted to the camshaft to detect which cylinders are approaching the top of their stroke, therefore which injector bank should be fired. During start-up below rpmor if there is no signal from the cylinder ID sensor, all injectors are fired simultaneously once per engine revolution. Predecessor of the ME Motronic.

Was also used in the Opel engine X22XE. The key feature of Motronic 1. This system was used by Volvo on some Volvo cars.

Fuel enrichment during cold-start is achieved by altering the timing of the main injectors based on engine temperature. The idle speed is also fully controlled by the digital Motronlc unit, including fast-idle during warm-up. Updated variants ML 2. Sequential fuel injection and knock control.

Late ’80s and early ’90s, various Ferrari. Successor of the Motronic 2. Was used from at Opel C20XE engine. Major change was the introduction of DIS ignition. Fuel enrichment during cold-start is achieved by altering the timing of the main injectors based on engine temperature, no “cold start” injector is required. The idle speed is also fully controlled by the Motronic unit, including fast-idle during warm-up therefore no thermo-time switch is required.

The ignition timing and fuel map electornica be altered to take account of fuels with different octane ratings by connecting a calibrated resistor taking the form of an “octane coding motroniic in the vehicle’s wiring loom to one of the ECU pins, the resistance depending on the octane adjustment required.


There is a single output for the injectors, resulting in all injectors firing simultaneously. The injectors are opened once for every revolution of the engine, injecting half the required fuel each time. It was introduced with the launch of the Turbo also called the T-5 and T-5 Turbo in October [16] for model year Electrojica included OBD I diagnostics, dual knock sensors and a lot more.

OBD II was standard on all cars fitted with this system albeit the necessary protocolls were not integrated for all markets. The electroniica was used for the five- and motroonic modular engined cars and was used on turbocharged and naturally aspirated models.

Introduced in for model year it was first installed on some of the last models [17] [19] like the 2. It was only used in cars equipped with V8 gasoline engines. This variant of the engine management system was adapted for off-road use. Unlike the Motronic system in BMW sedans, that uses a chassis accelerometer to differentiate between misfires and rough road, the Land Rover version used signal from ABS control unit to detect rough road conditions.

This version of the system was integrated with body control module and anti-theft system. From Wikipedia, the free encyclopedia.
