Is your car engine running rough, fuel consumption increased, or emission values incorrect? Then faulty injectors could be the cause. To check these, an injector tester is an indispensable tool for every workshop and ambitious DIY mechanic. But what exactly can such a device do, and what should you look for when buying one?
Functionality and Benefits of an Injector Tester
An injector tester, also known as a fuel injector tester, is used to check the function of your vehicle’s injectors. It simulates the operating conditions of the engine and allows you to analyze the spray pattern, leak tightness, and injection quantity of the injectors.
“Injectors are high-precision components that are essential for optimal combustion in the engine,” explains Dr. Ing. Stefan Müller, automotive expert and author of the book “Modern Car Diagnostics.” “An injector tester helps to detect faults early and prevent consequential damage to the engine.”
The advantages of an injector tester are obvious:
- Early detection of defects: Before major damage occurs, you can identify and replace faulty injectors.
- Accurate diagnosis: The tester provides you with precise data about the functioning of the injectors.
- Cost savings: By avoiding consequential damage and unnecessary repairs, you save money in the long run.
- Improved engine performance: Properly functioning injectors ensure optimal combustion, which leads to more power and lower fuel consumption.
