An interior burning engine is basically a large air pump that powers itself utilizing gas. As the air is absorbed, enough fuel needs to be supplied to produce power to maintain the engine's procedure while having an useful quantity left over to push the vehicle when called for. This mix of air as well as gas is called a 'mixture'.

Not just is the amount of mix important, yet the ratio of that combination needs to be correct. Way too much fuel - too little oxygen, and the burning is dirty as well as wasteful. Inadequate gas - way too much oxygen makes the combustion sluggish and also weak. Engines made use of to have this combination amount and ratio controlled by an entirely mechanical metering tool called a carburetor, which was little more than a collection of repaired size holes (jets) where the engine 'sucked' the fuel.

The only method to meet these rigorous needs is to turn over control of the engine to an ECU, the Engine Control Device. The ECU has the task of regulating the fuel shot, ignition as well as the original source ancillaries of the engine utilizing digitally kept equations and also numerical tables, instead of by analogue suggests.

The increase in air movement to the engine is gauged by the Mass Air Circulation sensor (MAF) so the ECU can change the quantity of gas that's infused, maintaining the mixture proportion within restrictions.

For finest power degrees and also risk-free combustion, the ECU needs to transform the ratio of the mix and also infuse even more fuel under top speed than it would certainly during cruising this is called a 'rich combination'. Alternatively, a fueling approach or a mistake that causes less than a normal quantity of gas being infused would result in a 'lean combination'.

Because petrol is injected as a liquid, dissipation needs to happen before it will combust.

This method was typically imprecise, problematic and also required normal modification. Several were adjusted by hand by the driver while driving.
