An interior burning engine is essentially a large air pump that powers itself utilizing fuel. As the air is trapped, enough fuel needs to be supplied to produce power to maintain the engine's operation while having a helpful amount left over to push the auto when needed.

Also little fuel - as well much oxygen makes the burning slow as well as weak. Engines used to have this combination amount and proportion managed by a completely mechanical metering device called a carburetor, which was little bit even more than a collection of dealt with size openings (jets) via which the engine 'sucked' the fuel.


The only way to satisfy these strict requirements is to hand over control of the engine to an ECU, the Engine Control Device.

For finest power degrees as well as risk-free combustion, the ECU should alter the proportion of the combination as well as inject even more fuel under top speed than it would certainly during cruising this is called a 'abundant mixture'. Conversely, a fueling technique or a fault that leads to much less than a typical quantity of fuel being injected would certainly result in a 'lean blend'.


Because gas is injected as a liquid, dissipation needs to take place website here before it will certainly ignite. In a warm engine, this is simple to manage, however in a chilly engine the fluid is much less likely to vapourise and also even more fuel should be injected to maintain the mixture ratio within the correct range for combustion.
