Is Cleaning Fuel Injectors Important? What Pros Need to Know for Their Auto Careers
Here’s what aspiring automotive professionals need to know about the importance (or lack thereof) of cleaning fuel injectors.
The Process of Fuel Injector Cleaning, Explained for Those With Auto Careers
When fuel injector systems need to be cleaned, there are multiple steps that are usually taken. First, the system is inspected to ensure that it still performs well, and can produce sufficient pressure for the injectors to function normally. After this, various parts of the system would be cleaned, such as the exhaust and throttle body. The purpose of fuel injectors is to deliver fuel into the engine, with the engine’s computer meant to dictate the delivery process. Some cars take this a step further, directly injecting fuel into cylinders rather than outside of it.
Why Are Fuel Injector Systems Cleaned? And Are They Still Important?
Fuel injector systems have typically replaced carburetors in more modern vehicles, as the latter typically needed to be cleaned on a regular basis. During the ‘80s, carburetors would begin to be steadily replaced by fuel injectors, and regular cleaning was not as necessary due in part to the higher amount of pressure fuel injectors would use. Furthermore, arguments can be made that adding cleaner to the fuel injection system every so often to flush out the deposits won’t be as effective as draining the injectors and taking them apart for a deeper clean. These systems are also not meant to be frequently opened, and the detergents found in gasoline can keep injectors stay clean by themselves.
