Frequently Asked Questions (FAQs)

1. Does the ECU control the fuel injectors?

The ECU is the brain of the operation. 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.

2. Do petrol cars have ECU?

Any fuel-injected car uses a computer ( ECU ) to control the injectors and usually the ignition. Before 1985 most vehicles used carburetors and DID NOT HAVE ANY ECUS!!..

3. What does an electronic fuel injection do?

Electronic fuel injection replaces the need for a carburetor that mixes air and fuel. EFI does exactly what it sounds like. It injects fuel directly into an engine's manifold or cylinder using electronic controls.

4. How does a petrol fuel injection system work?

A modern fuel injection system works by atomising the fuel at high pressure, mixing it with clean air as it passes the inlet manifold, before entering the combustion chamber of each cylinder. ... This often led to high emissions, poor fuel economy, misfiring engines, burnt valves and shorter engine life.
