Technology is becoming more modular. If something breaks — just replace it. The Lanchester Balancing System. So much so there are strict regulations to keep their operation as clean and as efficient as possible Meet the fuel injection system. What ever happened to the carburettor?
Too much fuel? The computer corrects the length of time the injector is held open. So, fuel injection systems are perfect? This is often expensive. Then again, how much money have you saved in fuel over the years? The 4 year MOT exemption on new cars being a perfect example. Found this post useful?

All engines produce contaminants and carbon, and these can build up with oil residue into a hard, greasy substance known as gunk.
How much gunk, and how much of a problem it will create, can depend on the manufacturer, the engine, and even who you ask — it can be a controversial subject for auto enthusiasts — as well as what to do about it. Routine injector flushes or cleaning additives are also controversial. Sign up to receive Driving. A welcome email is on its way. If you don't see it, please check your junk folder.

The fuel pressure regulator constricts the flow of fuel and only lets a calculated amount through to the injectors.
The fuel pressure regulator knows how much fuel to let through to the injectors via a signal from the mass airflow sensor MAF. This sensor tracks how much air is entering the engine at any given time. The fuel injectors themselves open to let the atomized gas directly into the combustion chamber or into a throttle body.
The main difference between the two systems is that mechanical fuel injection systems use mechanical devices to meter the correct amount of fuel into the engine. These systems have to be tuned for optimal performance, like carburetors, but also deliver fuel via injectors. They were, however, extremely useful for aircraft engines.
Carburetors do not work well against gravity. To deal with the g-forces dealt out by aircraft, fuel injection was developed. Without fuel injection, fuel starvation would have stalled many aircraft engines during tricky maneuvers. Going forward, fuel injection will become more and more precise and offer increasing efficiency and safety. Each year engines have more horsepower and produce less waste per horsepower.
