What is an Automotive Smoke Test Machine?

The automotive smoke test machine is a device that generates smoke. It sends the smoke into the vehicle’s Evap system at low pressure. This helps prevent any damage.
By visually inspecting the system, you can watch where the smoke escapes, which helps you pinpoint the exact leak. This makes repairs more accurate and efficient, saving time, reducing effort, and increasing customer satisfaction.

Why an Automotive Smoke Machine is important for you?

How Automotive Smoke Machines Work?

The automotive smoke machine employs a forced combustion smoke generation method in a lowoxygen environment. It is energized by a conductive column to the heating wire, which
rapidly heats up to more than 300°C so that the mineral oil reaches the ignition point and
enters the state of combustion. Due to the small intake of air flow, it is insufficient to provide
sufficient oxygen to maintain full combustion, thus the combustion mainly occurs on the
surface of the heating wire. Subject to high-temperature heating, the mineral oil retention
object can continue to burn insufficiently around the heating wire, thus producing a large
amount of smoke.

How to Choose the Right Automotive smoke machine for You？

Choosing the right automotive smoke machine ldepends on your vehicle type, diagnostic needs, and budget. Portable models with a built-in air pump offer convenience, while external air compressor models may provide stronger airflow but require additional equipment. Higher-end detectors feature adjustable smoke density and pressure settings, improving leak detection precision for systems like intake, exhaust, EVAP, and fuel tanks.

How to Properly Use an Automotive Smoke Machine？

1. Fill the Machine: Add 10-15 ml of baby oil to the smoke detector (for first-time use).
2. Disconnect the pipe that you need to connect to the smoke machine.
3. Power On: Connect the machine to the 12V battery, turn on the power switch, and let the machine begin generating smoke.
4. Inspect for Leaks: After about 30 seconds, smoke will start filling the pipe. Check for leaks and use a headlamp if needed.

warning tips

1.Be mindful of the gas and oil used in the machine
regular air instead or nitrogen.
baby oil instead of special mineral oil.
2.Ensure the heating pad is functioning properly.
3.If the pressure gauge isn’t working, troubleshoot the machine.
Try blocking the outlet and check if the pressure gauge is working.
4.Always check the input voltage to avoid damage.
