Engine Management

What it does

Engine management is the electronic control of an engine’s ignition and fuel systems. Many components are required to facilitate this.

In light of recent news stories, here at APSW we thought we'd write a topical article on the 'ol oxygen sensor (by the way, we have loads of in stock), more commonly known as the lambda sensor.

What they do?

A lambda sensor is an oxygen sensor that fits into the exhaust system. Its purpose is to send a voltage signal to the ECU relevant to the oxygen content of the exhaust gasses. The ECU uses this information to continually adjust the engine’s fuelling requirements.

Front Pipes

What they do

They connect the engine or manifold to the catalytic converter.

Fuel Pumps

What they do

All vehicles with engine management systems utilise an electric fuel pump, its purpose is to deliver fuel from the fuel tank to the engine/engine management system at the required pressure and delivery rate. The pressure and delivery rate vary according to the vehicle to which it is fitted.

Later vehicles are often fitted with a fuel pump module/assembly  which includes the fuel level gauge sender unit. It is also becoming more common place to incorporate the fuel pressure regulator into the same unit.
