AUTOOL 4-Cylinder Ultrasonic Injector Cleaner & Petrol Injection Tester Kit

Overview

Discover AUTOOL's 4-Cylinder Ultrasonic Injector Cleaner and Tester, an all‑in‑one solution for maintaining fuel delivery and smoother engine response. The system combines powerful ultrasonic cleaning with a microcomputer controlled closed‑loop fuel pressure module to mimic real engine conditions and assess injector performance without disassembly.

Designed for workshops and serious DIY enthusiasts, this kit emphasizes practical cleaning and precise diagnostics. It focuses on real‑world outcomes such as cleaner spray, balanced delivery across cylinders, and reliable idle behavior, while presenting options and outcomes as possibilities rather than guarantees.

Key capabilities

• 1800ml ultrasonic cleaning tank to batch clean multiple injectors or small components in one session.
• Dual cleaning reach: external surface cleaning plus internal passage cleaning by activating the injector’s valve with a controlled pulse signal for optimal flow.
• Back‑flush cleaning to reverse fluid flow and on‑vehicle cleaning without injector removal, reducing downtime.
• Compatibility with most common 5V and 12V injectors and standard EGI systems; suitable for gasoline and diesel injectors (specific low‑voltage direct injection types may be excluded).

Testing and diagnostics

• Nine test modes with electronic pressure regulation for steady, repeatable results and flexible diagnostics.
• Four 100ml test cylinders with bright backlighting allow simultaneous testing of up to four injectors with clear visual monitoring.
• Evaluate atomization quality, spray pattern, delivery volume, and leak conditions under idle, mid‑range, and high‑speed simulations.
• Designed to help technicians compare injector performance across cylinders, identify imbalances, and gain actionable insights from the visuals.

Practical use scenarios

• Service shops performing routine injector checks during maintenance or after fuel system work.
• Fleet or workshop settings cleaning multiple units together to improve workflow efficiency.
• On‑vehicle cleaning options to reduce downtime by avoiding injector removal when possible.

Usage, safety, and maintenance

Pour cleaning fluid only into the ultrasonic tank at the top of the machine. Do not pour liquids into internal chambers. For testing, use 99% purity ethanol in the designated glass tubes and pour through the included funnel. Do not exceed the marked fill line. Cleaning fluids are sold separately as professional injector cleaners.

For reliability, the device supports a clear workflow with repeatable test conditions. The manufacturer offers a three‑year parts warranty for non‑human factor damage, with lifelong maintenance support available on request. These features aim to provide dependable setup and ongoing assistance when you need it.
