Electronic systems and robotised gearboxes catalogue

The new 2020 Electronics catalogue is now available in both printed and PDF format. The applications and cross-references are also available on the TecDoc web platform.

The range includes 400 selected products from the Marelli Powertrain range (the business unit dedicated to the production of components for car, motorbike and light vehicle engines and gearboxes), and offers:
• engine control units
• throttle bodies
• injectors
• AMT (Automated Manual Transmission).

Magneti Marelli Parts & Services offers the original technology and quality to the independent aftermarket.
The new edition has been enhanced with updated graphics that make it easier to read and consult. Vehicle brands and models are shown both with their commercial name and industrial version; each product is identified with both short and long codes.

Clear explanatory notes are provided as necessary.
New icons have been introduced to reduce text and render reading even more immediate.
The entire range has been photographed to provide further support in identifying the correct part.

The first of the two sections in the catalogue (regarding ECU, throttle bodies and injectors) presents the products available for vehicles, photographs of each item, the main applications and the OE/OES – Magneti Marelli P&S cross-reference tables.

The section specifically dedicated to AMT presents the products with photographs, the main applications and cross-references with OES.

ECU

The Engine Control Unit (ECU) is the device that manages modern internal combustion engines. It collects inbound information from a series of sensors regarding the operational status of the engine.
This information is processed by various circuits in the unit in order to control the actuators that apply control strategies regarding fuel, combustion and emissions in relation to the programme stored in the memory and optimised during the experimentation and certification of the vehicle.

As well as these main functions, the unit also permits:
• full auto-diagnostics for both the inbound sensors and outbound actuators
• the recovery of malfunction signals on the basis of valid input
• engine lock (immobiliser) function

With the aid of diagnostic testers connected to the system, it is possible for an operator to view engine parameters and errors and carry out tests.

Electronics in the controlling of internal combustion engine is therefore used to improve performance, comfort, consumption and emissions, at the same time guaranteeing increasingly higher levels of reliability. Another important aspect is the possibility of auto-diagnosis that, through the logic and calculation capacities of the on-board electronics, automatically provides mechanics with a whole series of indications regarding the system status, leading them to an easy identification of malfunctions (thus rendering maintenance easier).
The current range in the catalogue offers more than 70 control units for diesel and petrol engines.

THROTTLE BODIES (and Intake manifolds for both diesel and petrol engines)

The throttle body is the main component in the intake manifold, of which it is often an integral part. It is responsible, via the “throttle”, for dosing the quantity of air supplied to the engine according to demand from the driver via the accelerator.
Marelli designs and manufactures throttle bodies and intake ducts (CAB and CAD) for both petrol and diesel engines.

Magneti Marelli P&S offers a range of 140 complete products and 60 spare parts (regulators and stepper motors).
