Special Functions – Injectors scaling

Why scale the injectors?

Fuel Injection is the introduction of fuel in an internal combustion engine by the means of an injector. There are two main functional principles of mixture formation systems for internal combustion engines: internal mixture formation and external mixture formation.

A fuel injection system that uses external mixture formation is called a manifold injection system (multi point injection, single point injection).

Internal mixture formation systems can be separated into direct and indirect injection systems. The term electronic fuel injection refers to any fuel injection system having an engine control unit (ecu).

An injector is a system of ducting and nozzles used to direct the flow of a high pressure fluid in such away that a lower pressure fluid is entrained in the jet and carried though a duct to a region of higher pressure.

When the tuning exceeds the stage 1 it may be necessary to replace the original injectors with injectors with a higher flow rate.

We can help you with specific maps to replace the original injectors with injectors with higher flow rate.

If the vehicle and engine control unit are supported with this function, you will find the Injectors Scaling mark in column “special functions”.
