What does the engine control module control?
An engine control unit (ECU), also commonly called an engine control module (ECM) is a type of electronic control unit that controls a series of actuators on an internal combustion engine to ensure optimal engine performance. The fuel injection system has the major role of controlling the engine’s fuel supply.
What does the engine control module typically provide to control the fuel pump?
The fuel pump is driven by a signal that changes the power to control the speed of the motor and pressure delivered to the fuel rail during the duty cycle. The driver for these fuel pump circuits is typically part of the engine control module.
How does the ECU control fuel?
Electronic Control Unit (ECU) It uses engine RPM and signals from different sensors to meter the fuel. It does this by telling the fuel injectors when and how long to fire. The ECU often controls other functions like the fuel pump and ignition timing.
What does a fuel pump flow control module do?
These modules help control the voltage delivered to your vehicle’s fuel pump, helping to regulate the fuel pump’s speed. These modules also help maintain optimum fuel pressure, and fuel delivery to your vehicle’s engine.
What is the name of the engine control module?
The engine control module (ECM), also commonly referred to as the engine control unit (ECU) or powertrain control module (PCM), is one of the most important components found on virtually all modern vehicles.
Is the fuel pressure regulator connected to the manifold vacuum?
Typical aftermarket manifold referenced fuel pressure regulator. For many applications, the fuel pressure regulator is not connected to manifold vacuum. This is very popular in naturally aspirated engines. Instead, the engine calibration is tuned to accommodate a near constant/static change in fuel pressure.
How is the engine control unit ( EEMS ) controlled?
The whole mechanism of the EEMS is controlled by a stack of sensors and actuators. Most modern engines use some type of fuel injection to deliver fuel to the cylinders. The ECU determines the amount of fuel to inject based on a number of sensor readings.
