While not a guaranteed fix, it provides a structured workflow that helps you evaluate injector performance, observe cleaning outcomes, and explore how direct-injection technology behaves under controlled conditions. Built to support both standard injectors and GDI designs, this unit offers a clear pathway to better maintenance habits for vehicles that rely on precise fuel delivery.\u003c\/p\u003e\n\n\u003ch3\u003eWhat makes the CT400 stand out\u003c\/h3\u003e\n\u003cp\u003eEngineered around ultrasonic cleaning and smart control, the CT400 expands beyond simple cleaning by simulating engine-like conditions to help you assess injector function. It supports multiple high-pressure voltages (12V, 70V, 120V) and includes a cooling fan and thermal protection to help it run reliably during longer sessions. A bright LED-backlit digital panel makes it easy to monitor the process at a glance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eGDI compatibility: cleans and tests both standard and direct-injection injectors, suitable for many direct-injection engines\u003c\/li\u003e\n  \u003cli\u003eVoltage versatility: drives high-pressure injectors across 12V, 70V, and 120V ranges\u003c\/li\u003e\n  \u003cli\u003eThermal safety: cooling fan and protection help extend the machine’s service life\u003c\/li\u003e\n  \u003cli\u003eSmart operation: high-definition digital control panel and LED backlight for clear observation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSmart design for real-world use\u003c\/h3\u003e\n\u003cp\u003eThe CT400 combines ultrasonic cleaning with microcomputer oil pressure closed-loop control. It not only cleans injectors but also enables leakage testing and system checks, all in a compact 6-cylinder package. A test liquid discharge valve lets you clearly observe the liquid content and even reuse the cleaning solution, reducing waste and simplifying workflow.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eUltrasonic cleaning plus closed-loop control for consistent cleaning performance\u003c\/li\u003e\n  \u003cli\u003eVisible discharge valve for monitoring liquid flow and enabling reuse\u003c\/li\u003e\n  \u003cli\u003eDigital panel with bright display for easy setup and monitoring\u003c\/li\u003e\n  \u003cli\u003eMotor and electronics designed for ongoing reliability, with a 3-year parts warranty for non-human-factor damage\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eReal‑world benefits you may notice\u003c\/h3\u003e\n\u003cp\u003eUsing the CT400, technicians can explore injector behavior under simulated engine conditions. While results vary by vehicle and maintenance history, users frequently report smoother operation, more predictable idle, and clearer insights into fuel delivery quality. This tool helps you observe how clean injectors contribute to stable performance and may support easier diagnostics in a professional workflow.\u003c\/p\u003e\n\n\u003ch3\u003eReliable support for workshops\u003c\/h3\u003e\n\u003cp\u003eAUTOOL backs the CT400 with a three-year warranty covering parts for non-human-factor damage and offers responsive support.
