1. Product Overview
The MRCARTOOL V309 is a professional mechatronic device designed for the diagnosis and cleaning of fuel injectors. It integrates ultrasonic cleaning technology with microcomputer-controlled oil pressure and circuit detection. This system supports the simulation of various engine operating conditions to thoroughly clean and inspect both standard and high-pressure EFI/FSI/GDI injectors.
Key features include:
- Ultrasonic Cleaning: Efficiently removes carbon deposits and impurities from injectors.
- Comprehensive Testing: Offers 9 distinct test functions to evaluate injector performance under various conditions.
- Smart Operation Panel: Digital controls for precise adjustment of test parameters and injection voltages (12V/70V/120V).
- 4-Cylinder Capacity: Equipped with four 140ml cylinders, allowing simultaneous cleaning and testing of up to four injectors.
- Wide Compatibility: Suitable for 99% of vehicles, including those with GDI, EFI, and FSI systems.

5. Operation
5.1 Control Panel Overview
The intelligent control panel allows for precise control over all cleaning and testing functions. It features digital displays for pulse adjustment and working/injecting times, along with buttons for voltage selection and function control.
Figure 5.1: Intelligent Operation Panel with function descriptions.
5.2 Ultrasonic Cleaning Procedure
- Place the injectors into the ultrasonic cleaning bracket within the ultrasonic bath.
- Ensure the injectors are submerged in the cleaning fluid.
- Turn on the power switch.
- Select the 'Ultrasonic Cleaning' function on the control panel.
- Adjust the cleaning time as required using the panel controls.
- Press the Start button to begin the ultrasonic cleaning process.
- After cleaning, remove the injectors and rinse them thoroughly.

5.3 Injector Testing Procedures
The V309 offers 9 distinct test functions to assess injector performance:
- Idle Speed Test: Checks spray pattern and volume at idle RPM.
- Medium Speed Test: Evaluates performance at medium engine speeds.
- Acceleration Test: Simulates rapid acceleration conditions.
- Variable Speed Test: Tests performance across a range of RPMs.
- Leak Checking Test: Detects any fuel leakage from the injector.
- Idle Spray Volume Test: Measures fuel volume at idle.
- Medium Spray Volume Test: Measures fuel volume at medium speed.
- High Spray Volume Test: Measures fuel volume at high speed.
- High Speed Test: Assesses performance at high engine speeds.
To perform a test:
- Install the injectors onto the test bench and connect the pulse signal cables.
- Ensure the test cylinders are empty and the drain valve is closed.
- Select the desired test function from the control panel.
- Adjust parameters such as pulse width and injection times if applicable.
- Select the appropriate injector voltage (12V, 70V, or 120V) based on the injector type.
- Press the Start button to begin the test. Observe the spray pattern and measure the fuel volume in the graduated cylinders.
- Compare the results with manufacturer specifications to determine injector health.
