MR CARTOOL V308 Injector Cleaner Machine
The MR CARTOOL V308 blends ultrasonic cleaning with a built-in heater to remove carbon deposits from up to four injectors at once. Its 2000 ml tank supports batch processing, and the unit offers 11 main functions including idle, medium, and high-speed tests, as well as various spray-volume tests. A heating option helps improve cleaning effectiveness by raising the cleaning fluid temperature to about 40 degrees Celsius, enabling more thorough deposit removal without disassembly. The compact design emphasizes ease of operation, real-time monitoring, and clear diagnostics via its control panel.
Mrcartool V308 Fuel Injector Cleaner Machine
Similar in design to the MR CARTOOL V308, this unit emphasizes four-injector cleaning with an ultrasonic bath and 2000 ml tank capacity. It features a user-friendly LED display, pressure gauge, and glass testing tubes to visually monitor injector performance during automated tests. The device supports rapid carbon removal and enables quick assessment of injector leakage, uniformity, and spray characteristics, making it suitable for small shops and DIY enthusiasts working on diesel and gasoline injectors.
AUTOOL Fuel Injector Cleaner Tester Machine
AUTOOL’s ultrasonic cleaner offers 4-cylinder cleaning with a heating mode that brings the cleaning fluid to about 45°C. It provides 9-in-1 diagnostic testing—covering leakage, spray pattern, flow and volume under idle and acceleration conditions—and includes adjustable digital control to work with different injector types, including high-pressure direct injection. Its modular adapters help accommodate a variety of engine configurations, making it versatile for diesel and gasoline injector maintenance without disassembly.
YUANRI Fuel Injector Cleaner Machine
YUANRI’s 11-mode diagnostic system evaluates spray pattern, leakage, clogging, and fuel delivery across idle, medium, and high-speed engine states. The unit features a dual-capacity approach: a modest 140 ml test cylinder for testing up to four injectors and a large 2000 ml tank for batch cleaning. The built-in heater can reach about 45°C, improving carbon removal performance. The compact design prioritizes batch processing efficiency and real-time measurement of detection values to support diagnostics alongside cleaning.
MR CARTOOL V209 GDI Injector Cleaner Machine
MR CARTOOL V209 combines ultrasonic cleaning with controlled oil pressure for cleaning and testing 4 injectors simultaneously. It simulates a wide range of engine operating conditions to accommodate various GDI and standard injectors. The system supports automatic heating during ultrasonic cleaning to improve deposit removal and provides 10 distinct test functions, including multiple speed tests and leakage checks, for a robust assessment of injector health and performance.
MR CARTOOL V309 GDI Injector Cleaner
MR CARTOOL V309 integrates ultrasonic cleaning with microcomputer-controlled oil pressure closed-loop management to clean and test high-pressure EFI/FSI/GDI injectors. It supports simulating engine conditions to test standard and GDI injectors, with 9 testing functions and a strong 4-cylinder cleaning platform. The device emphasizes compatibility with a wide range of vehicles, offering precise control and real-time feedback during both cleaning and diagnostic testing.
Buying Guide
- Injector compatibility: Ensure the machine supports your engine types (diesel, gasoline, GDI/FSI). Look for models advertising compatibility with high-pressure injectors and adapters for multiple brands.
- Cleanliness and capacity: Consider the tank size (2000 ml is common) for batch cleaning, and confirm the unit can handle the number of injectors you service per cycle.
- Heating and ultrasonic performance: Heating improves deposit removal; higher ultrasonic frequency and power can speed up cleaning and deliver deeper cleaning results.
- Diagnostics and testing: Look for multiple test modes (leakage, spray pattern, flow, velocity) and engine-condition simulations to verify injector health beyond cleaning.
- Ease of use and maintenance: Features such as clear displays, glass testing tubes, and pressure gauges help operators monitor tests. Check for replaceable cleaning fluids and ease of cleaning the tank and components.
- Safety and certifications: Verify electrical ratings (110V or 220V) and any safety features for heating, fluid handling, and electrical safety compliance.
- Price-to-performance balance: Compare total testing capabilities, batch-cleaning capacity, and build quality relative to cost. Some kits offer stronger value for busy shops with high throughput.
- Support and availability of spare parts: Check for availability of replacement parts, adapters, and cleaning fluids compatible with your preferred brands and vehicles.
