What makes the injectors spray?

Fuel injectors are located in the intake manifold and spray fuel through a tiny nozzle. The fuel injector uses a special nozzle to spray the fuel as mist, instead of a strong jet stream. Just think of the nozzle on the hose you use in your yard. You can change how the water flows out of your nozzle.

What do injectors and carburetors spray?

Fuel Injectors and Carburetors Fuel injectors do just what they say – they are nothing more than a spray nozzle in the intake manifold. A carburetor sits on top of the manifold and uses jets that meter gas into the intake manifold. For good combustion, a fine cone-shaped mist of fuel vapor is necessary.

Can I use fuel injector cleaner for carburetor?

Can I use Gumout Fuel Injector Cleaner in an engine with a carburetor? Yes. Carburetor deposits are typically easier to clean than fuel injector deposits, and the chemistry used in the fuel injector cleaner will also effectively clean carburetors.

Where are the spray patterns on the injector?

It is located where the carburetor used to be and the fuel doesn’t hit the hot intake valve that would atomize the fuel like the multi port injector systems. It has to spray the fuel in a wider pattern to help mix it with the air better. In conclusion: There are quite a few different types of spray patterns.

How can I keep my fuel injector in good health?

Fuel injectors are a vital part of a complex fuel management system. Furthermore, New technology has made fuel injectors more precise than ever in dispensing fuel. If the fuel injectors are not operating properly, then other parts of the engine will be affected as well.

When do you assume there is enough pressure in the injectors?

If the engine runs, they assume the injectors are getting adequate fuel pressure. If the engine cranks but won’t start, and they depress the service valve on the fuel rail and some fuel squirts out, they assume the injectors have pressure. They do, but the question remains, “How much pressure?”

What should you know about DIY Fuel injector cleaning?

During the DIY fuel injector cleaning process the spray pattern which indicates atomization and distribution cannot be verified. The spray pattern of a fuel injector is very important the performance of the engine. It can also be determine the amount of Hydrocarbon [HC] and Carbon Monoxide [CO] that will be emitted.

What can cause bad fuel injector spray patterns?

Incorrect or poor fuel injector spray patterns can cause a wide range of drive-ability issues such as emissions, poor starting, poor fuel consumption and even engine detonation. The injectors in the image flow exactly the same amount of fuel. It is the spray patterns that is noticeably different.

Can you use detergent on a rusty fuel injector?

Fuel regulations require minimum levels of detergent additives, but these cannot compensate for a rusty gas tank or a degraded fuel filter. In extreme cases, this compromises the fuel injector spray pattern, and the PCM will see this, store a code and display a check engine light.
