AUTOOL CT200 Injector Ultrasonic Cleaner & Tester

•  1. Cylinder Testing Capacity

The FN608 supports testing for 8 cylinders, while the FN606 supports testing for 6 cylinders.

• 2. Pump Configuration

The FN608 is equipped with two independent fuel pumps, each corresponding to a separate fuel rail (left and right). Both pumps operate independently during testing — if one pump fails (e.g., the left pump), only the corresponding fuel rail is affected, while the other continues to function normally. This dual-pump system ensures greater reliability and uninterrupted testing. The FN606, on the other hand, has a single fuel pump, meaning that if it fails, the entire system stops working until the pump is replaced.

•  1. Cylinder Testing Capacity

The FN608 supports testing for 8 cylinders, while the CT500 supports testing for 6 cylinders. This makes the FN608 more suitable for high-capacity or multi-cylinder engine injectors.

• 2. Heating Function

The FN608 features a heating cleaning tank capable of maintaining a constant temperature up to 50°C, which significantly improves cleaning efficiency and performance. In contrast, the CT500 does not support heating, offering a more basic cleaning function.

• 3. Voltage Settings

The FN608 supports multiple voltage ranges — 12V, 12–70V, and 120–180V — making it compatible with a wider variety of injector types. The CT500, however, supports only 12V, 70V, and 120V, providing more limited voltage adaptability.

• 4. Cleaning Tank Design

The FN608’s cleaning tank can be used independently or together with the main unit, providing greater flexibility for maintenance and cleaning. The CT500’s cleaning tank is integrated with the main body and cannot be used separately, limiting its independent operation.

• 5. Pump Configuration

The FN608 is equipped with two independent fuel pumps, each corresponding to a separate fuel rail (left and right). Both pumps operate independently during testing — if one pump fails (e.g., the left pump), only the corresponding fuel rail is affected, while the other continues to function normally. This dual-pump system ensures greater reliability and uninterrupted testing. The CT500, on the other hand, has a single fuel pump, meaning that if it fails, the entire system stops working until the pump is replaced.

• 1. Testing Functions:

The CT450 adds the Pulse Injection Test compared to the CT400, while the CT500 further adds Wide Pulse Injection Test and Continuous Injection Test compared to the CT450, offering more advanced and versatile injector testing capabilities.

• 2. Cleaning & Heating Function:

The CT450 features ultrasonic cleaning with heating up to 50°C, whereas the CT400 and CT500 do not have a heating function, making CT450 more effective for thorough injector cleaning.

• 1. Supported Injector Types

CT200 only supports 12V standard fuel injectors, whereas CT400 supports both 12V standard and GDI (Gasoline Direct Injection) injectors, making it compatible with a wider range of injector types and vehicles.

• 2. Accessory Storage Design

CT200 does not have dedicated accessory storage, while CT400 features a drawer for injector adapters and other accessories, providing more convenient organization and storage.

• Both the CT150 and CT160 are designed for cleaning and testing fuel injectors of 4-cylinder gasoline engines.
  The main difference is that the CT160 is equipped with an ultrasonic heating function, while the CT150 does not have this feature.
• Compared with the CT150, the CT200 simply adds two more testing cylinders (6 in total), while the other functions remain the same.
• If you only need a tester for 12V gasoline fuel injectors, the CT160 is an excellent choice.
  However, if you need to test GDI (Gasoline Direct Injection) high-pressure injectors, we recommend choosing CT400, CT450, CT500, FN606, or FN608 for better compatibility and performance.
