Fundamentally, the engine ECU controls the shot of the gas and, in petroleum engines, the timing of the spark to spark it.

Not only is the quantity of combination vital, but the proportion of that combination needs to be correct. Excessive gas - insufficient oxygen, and also the burning is filthy and also wasteful. Too little fuel - as well my response much oxygen makes the burning sluggish and weak. Engines used to have this combination quantity and proportion controlled by an entirely mechanical metering device called a carburetor, which was little bit greater than a collection of repaired size openings (jets) where the engine 'drew' the gas.

The only method to meet these rigorous needs is to turn over control of the engine to an ECU, the Engine Control Unit. The ECU has the work of managing the fuel shot, ignition as well as ancillaries of the engine using electronically saved equations and numeric tables, as opposed to by analogue implies.

For finest power degrees and safe combustion, the ECU must change the proportion of the blend and also inject more fuel under top speed than it would throughout travelling this is called a 'abundant combination'. Conversely, a fueling approach or a fault that results in much less than a normal quantity of fuel being infused would cause a 'lean mixture'.

Because gas is infused as a fluid, dissipation has to occur before it will ignite.
