Original Brand New 4354558 Electronic Control Module for Cummins

Original Brand New 4354558 Electronic Control Module for Cummins

Manufacturer number: 4354558

Country/Region of Manufacture: USA

Function: The Electronic Control Module (ECM) is responsible for managing and controlling various functions, such as fuel injection, ignition timing, and emissions control. It monitors and adjusts these parameters in real-time to optimize engine performance, fuel efficiency, and overall operation.

Composition: It is composed of microprocessor, memory, output/input interface, analog-to-digital converter, shaping, driving and large-scale integrated circuit.

Working principle: When the engine is running, ecu collects signals from various sensors, compares and calculates them, and converts the results of comparison and calculation into control signals to control ignition, air fuel ratio, idle speed, exhaust gas re-circulation and other parameters of the engine.

The Engine Control Unit (ECU) is the core of the automotive engine control system. It can provide the engine with the optimal air-fuel ratio mixture and ignition time according to different operating conditions, so that the engine is always in the best working state, thereby achieving the best performance (power, economy, emissions). The working principle of ECU is similar to that of a regular computer, consisting of a microprocessor (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), and large-scale integrated circuits such as shaping and driving. It can be metaphorically referred to as the “brain of a car”. The voltage working range of ECU is generally 6.5-16V (with a voltage stabilizing device at key internal points), with a working current of 0.015-0.1A and a working temperature of -40 ℃ -80 ℃.
