 What is a smoke machine leak detector?

The smoke machine leak detector is mainly used to check the sealing condition of various parts of the automobile. The smoke machine leak detector is mainly composed of smoke generating host, smoke generating liquid, smoke pipe, automobile import adapter and plug kit and other components. The smoke generating host injects a certain amount of smoke into the system under test through the smoke duct and the air inlet adapter, and judges whether the system has a leak position by observing the position where the smoke emerges.
Smoke machine leak detector can be used in almost any vehicle low-pressure system suspected of leaking, such as: intake and exhaust systems, other vacuum systems, fuel evaporative emission control system (EVAP), fuel supply system, electric vehicle power battery gas Tightness, and find the leak location of the door/window, skylight sealing strip. In addition, it can also be used for function inspection and component testing of solenoid valves.

What is the use of a smoke machine leak detector?

1. Check the tightness of the gas pipeline

When the engine has faults such as inaccurate mixture concentration (too rich or too lean), insufficient boost pressure, etc., use a smoke machine leak detector to fill the engine’s intake system with smoke to quickly determine whether the fault is related to the intake system leakage , Such as loose pipe connection clamps, pipe cracks, gasket leakage, intercooler leakage and component installation parts leakage, etc.

2. Detect the tightness of mechanical parts inside the cylinder

Turn the piston of the cylinder under test to the compression top dead center position (at this time, the intake and exhaust valves should be in the closed position), and then use a smoke machine leak detector to fill the spark plug installation hole with smoke, if the smoke comes from the exhaust pipe If smoke comes out, it means that the exhaust valve is not tightly closed; if smoke comes out of the intake pipe (observable from the throttle), it means that the intake valve is not tightly closed; if the smoke comes out of the spark plug mounting hole of the adjacent cylinder, It means that the cylinder head gasket is interoperable.

3. Check the tightness of the EVAP system

In order to prevent fuel vapor from leaking into the atmosphere, all vehicles that meet the National VI vehicle emission standards have the EVAP system leakage diagnosis function. When the engine control unit detects that the EVAP system may leak, the computer board of the conference machine will store the relevant fault code. At this point, the smoke machine leak detector can be used to find the specific location of the EVAP system leak.
