Car Smoke Leak Detector

A car smoke leak detector is a diagnostic tool used to identify leaks in a vehicle’s emissions system, specifically the evaporative emissions (EVAP) system. This system is responsible for capturing fuel vapors that evaporate from the fuel tank and fuel system components, and routing them back into the engine for combustion.

How it works:

1. Smoke Generation: A smoke machine generates a non-toxic, visible smoke.
2. System Pressurization: The smoke machine is connected to the vehicle’s EVAP system, pressurizing it.
3. Leak Detection: If there are any leaks in the system, the smoke will escape and become visible.
4. Visual Inspection: A technician can visually inspect the vehicle to locate the source of the leak.

Why it’s important:

• Environmental Impact: A leaking EVAP system can release harmful pollutants into the atmosphere.
• Vehicle Performance: A leak can cause issues with fuel economy, engine performance, and emissions test failures.
• Safety: In severe cases, a leak can lead to a fire hazard.

Common applications:

• EVAP system diagnosis: Identifying leaks in hoses, connectors, and other components.
• Intake manifold leaks: Detecting leaks in the intake manifold gasket.
• Vacuum leaks: Finding leaks in vacuum lines and hoses.

By using a smoke leak detector, technicians can accurately diagnose and repair EVAP system issues, ensuring that vehicles meet emissions standards and operate efficiently.
