Introduction

Fuel injectors are critical components in every gasoline engine, directly impacting power output, fuel efficiency, and emissions. Over time, poor-quality fuel or prolonged low-speed operation can lead to carbon deposits, blockages, and leaks, resulting in unstable idling, increased fuel consumption, weak acceleration, starting difficulties, and excessive emissions. In severe cases, clogged injectors can cause irreversible engine damage. The ANCEL ANJ400 addresses these challenges by combining powerful ultrasonic cleaning with precise diagnostic testing, offering a cost-effective, efficient, and environmentally friendly solution to restore and maintain injector performance.

Priced competitively for an entry-level professional tool, the ANJ400 is ideal for gasoline cars and motorcycles, including those with advanced GDI systems found in brands like Mercedes-Benz, BMW, Audi, Porsche, and Ford. Its compact design, intuitive operation, and robust feature set make it a versatile choice for both professional workshops and DIY users looking to save on costly repairs and injector replacements.

. Comprehensive Injector Testing Capabilities

The ANJ400 offers a wide range of diagnostic tests to evaluate injector performance under various conditions, ensuring accurate diagnosis and optimal functionality:

• Resistance Test: Measures the resistance of each injector (with 0.1Ω accuracy) to identify electrical faults, shorts, or current draw issues.

• Leakage Test: Assesses the sealing and dribbling conditions of injectors under system pressure to detect leaks that could affect performance.

• Injecting Flow Test: Quantifies the injection volume of each injector over 15 seconds of constant injection, ensuring consistent fuel delivery.

• Uniformity/Sprayability Test: Evaluates the uniformity of fuel injection across all injectors and monitors spray patterns using a backlight for clear visualization, ensuring smooth atomization.

• Working Modes Test: Simulates various engine operating conditions, including:

  • Idle Speed Test (0-20ms): Tests injector performance at low RPM.

  • Medium Speed Test (0-7.5ms): Evaluates injectors at moderate RPM.

  • High-Speed Test (0-4ms): Assesses performance under high RPM.

  • Acceleration Test: Simulates rapid throttle changes.

  • Deceleration Test: Tests injector response during slowdown.

  • Variable Speed Test: Evaluates performance across a range of speeds.

• Reverse Cleaning: Flushes injectors in the opposite direction to remove internal debris, enhancing cleaning effectiveness.

• On-Vehicle Cleaning: Includes a variety of disassembly-free cleaning connectors, allowing maintenance directly on the vehicle for added convenience.

3. Injector Installation: Secure injectors on the main machine for testing.

4. Electrical Testing: Perform resistance, shorts, and current draw tests.

5. Performance Testing: Conduct leak, spray pattern, and flow rate tests on the flow bench.

6. Retesting: Return injectors to the flow bench to verify all functions post-cleaning.

Recommended Cleaning and Testing Sequence

For optimal results, follow this sequence:

1. Ultrasonic Cleaning

2. Uniformity/Sprayability Test

3. Leakage Test

4. Injecting Flow Test

5. Working Modes Test

Post-Operation Procedure

1. Drain the test solution into a fuel container.

2. Switch off the power and unplug the machine.

3. Remove residual cleaning fluid from the ultrasonic pool and wipe it dry.

4. Clean the machine’s tabletop with a soft, dry cloth.

5. Dispose of used test fluid according to local regulations or store reusable fluid safely.

Fluid Selection Guidelines

• Test Fluid: Use professional automotive injector test fluids for accurate results. If unavailable, medical alcohol (75%+) can be used as a substitute, though results may be less optimal. The test fluid should be colorless, non-corrosive, and odorless to simulate injector performance accurately.

• Cleaning Fluid: Opt for professional ultrasonic cleaning fluids to remove carbon deposits effectively. Alternatively, 75%+ medical alcohol can be used, but it may be less effective. Avoid corrosive fluids, as they can damage the machine’s components.
