Before You Order And Use<\/div>\n

Before You Order And Use<\/h2>\n

Review the diesel injector limitation, fluid rules, ultrasonic cleaning requirement, voltage selection, and single-injector testing setup before using the CT500 injector cleaning machine.<\/p>\n <\/div>\n

\n
\n

Diesel Cleaning Only<\/h3>\n

Diesel injectors are supported for cleaning only. CT500 does not support testing diesel injectors.<\/p>\n <\/article>\n

\n

Do Not Test With Cleaning Fluid<\/h3>\n

Use professional injector test fluid for testing. Corrosive cleaning fluid may damage internal parts, rubber seals, and cause leakage if used for testing.<\/p>\n <\/article>\n

\n

Add Cleaning Fluid First<\/h3>\n

Before ultrasonic cleaning, add professional engine carbon cleaning fluid or ultrasonic injector cleaning fluid. Do not run ultrasonic cleaning dry.<\/p>\n <\/article>\n

\n

Keep Fluids Away From Flame<\/h3>\n

Testing and cleaning fluids may be flammable. Keep the machine away from open flames and monitor it during operation.<\/p>\n <\/article>\n

\n

Do Not Use Gasoline As Test Fluid<\/h3>\n

Do not use gasoline as injector test fluid. Use professional injector test fluid or the safer alternatives described in the fluid guide.<\/p>\n <\/article>\n

\n

Single Injector Testing<\/h3>\n

When testing a single injector, plug the other five cylinders. CT500 includes five plugs for this setup.<\/p>\n <\/article>\n

\n

Select Voltage Carefully<\/h3>\n

For GDI injectors, start from 12V and increase to 70V or 120V only when needed. Avoid using an incorrect voltage for an extended time.<\/p>\n <\/article>\n

\n

Heating Limitation<\/h3>\n

CT500 does not support heated ultrasonic cleaning. Choose CT450, FN606, or FN608 if a 50\u00b0C heating tank is required.<\/p>\n <\/article>\n

\n

Capacity Label Check<\/h3>\n

Product specifications list a 140ml test tube amount, while some comparison and feature images show a 110ml tube scale. Confirm with support if exact tube capacity is critical.<\/p>\n <\/article>\n <\/div>\n <\/section>\n\n

\n
Compatibility And Fitment<\/div>\n

Compatibility And Fitment<\/h2>\n

CT500 is designed for gasoline injector cleaning and testing across standard injectors, EFI, FSI, and GDI injectors. It is suitable for automotive repair shops, motorcycle maintenance, research teaching, and training departments that need repeatable injector comparison.<\/p>\n

\n
\n

GDI Injectors<\/h3>\n

Supports GDI injector cleaning and testing with 12V, 70V, and 120V driving modes for different injector requirements.<\/p>\n <\/article>\n

\n

EFI \/ FSI \/ Standard Injectors<\/h3>\n

Compatible with EFI, FSI, and standard gasoline injectors used in many European, American, and Asian vehicle applications.<\/p>\n <\/article>\n

\n

6-Cylinder Workflows<\/h3>\n

Supports simultaneous cleaning and testing of up to six injectors for faster comparison and workshop service.<\/p>\n <\/article>\n

\n

Diesel Injectors<\/h3>\n

Diesel injectors may be cleaned only. CT500 does not support diesel injector testing.<\/p>\n <\/article>\n <\/div>\n <\/div>\n

Key Features<\/div>\n

Key Features<\/h2>\n

CT500 focuses on injector compatibility, six-cylinder testing efficiency, ultrasonic cleaning, stable pressure control, practical storage, and visible test observation.<\/p>\n <\/div>\n

\n
\n

Wide Injector Support<\/h3>\n

Covers GDI, EFI, FSI, and standard gasoline injectors, including direct-injection applications used by brands such as Mercedes-Benz, BMW, Audi, Porsche, and Ford.<\/p>\n <\/article>\n

\n

Three Voltage Modes<\/h3>\n

12V, 70V, and 120V voltage selections help match different injector driving needs during GDI and gasoline injector testing.<\/p>\n <\/article>\n

\n

70W Ultrasonic Cleaning<\/h3>\n

Ultrasonic cleaning power up to 70W, with cooling fan and thermal protection, helps remove carbon deposits and impurities from injectors.<\/p>\n <\/article>\n

\n

6-Cylinder And Dual Drain<\/h3>\n

Six nozzles can be cleaned and tested at the same time. Two control valves help discharge liquid and recover test fluid for repeated use.<\/p>\n <\/article>\n

\n

Color Display And Pressure Control<\/h3>\n

The color display, multifunction control panel, and electronic pressure regulation help make injector tests clearer and easier to adjust.<\/p>\n <\/article>\n

\n

Drawer And Accessory Storage<\/h3>\n

The bottom drawer uses marked storage areas for adapters and components, helping reduce accessory loss during daily workshop use.<\/p>\n <\/article>\n <\/div>\n

Functions And Test Coverage<\/div>\n

Functions And Test Coverage<\/h2>\n

CT500 groups injector service into cleaning functions, spray pattern checks, flow comparison, leakage checks, and simulated operating-condition tests.<\/p>\n

\n
\n

Cleaning Functions<\/h3>\n

Ultrasonic cleaning, reverse flushing, and no-disassembly cleaning. No-disassembly cleaning requires special adapters; reverse flushing is only for top fuel supply injectors.<\/p>\n <\/article>\n

\n

Spray And Flow Checks<\/h3>\n

Related Guides<\/div>\n

Related Guides<\/h2>\n

Testing and cleaning use different fluids. Keep them separate to protect the machine, rubber parts, internal components, and injector test accuracy.<\/p>\n <\/div>\n

\n
\n

Test Fluid<\/h3>\n

Use professional automotive injector test fluid for performance testing. It is designed to be colorless, odorless, non-corrosive, and stable for simulating injector working states.<\/p>\n <\/article>\n

\n

Cleaning Fluid<\/h3>\n

Use professional injector ultrasonic cleaning fluid or engine carbon cleaning fluid to remove carbon deposits and impurities during ultrasonic cleaning.<\/p>\n <\/article>\n

\n

75%+ Medical Alcohol Alternative<\/h3>\n

If professional fluid is unavailable, 75%+ medical alcohol may be used as an alternative, but cleaning effectiveness may be reduced and flammability precautions still apply.<\/p>\n <\/article>\n <\/div>\n
