| Vehicle Type | Test Type | Description |
|---|---|---|
| Petrol Vehicles | CO Test | Measures CO emissions for proper fuel combustion |
| Diesel Vehicles | Smoke Density Test | Measures black smoke emissions for fuel combustion efficiency |
| CNG/LPG Vehicles | HC Test | Measures unburnt hydrocarbons to check fuel combustion |
| All Vehicles | CO2 Test | Measures CO2 emissions to assess environmental impact |
Pre-Test Inspection: A quick check of the vehicle’s exhaust system is conducted to ensure there are no visible damages or leaks that could affect the accuracy of the emission test.
Connecting Testing Equipment: The vehicle’s exhaust is connected to an emission testing machine that measures pollutants such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).
Engine Running Test: The engine is run at different speeds (idle and accelerated) to analyze emissions under various operating conditions.
Data Recording: The machine records the emission levels and compares them with government-specified limits for the vehicle category and fuel type.
Certificate Issuance: If the vehicle passes, an emission certificate is issued, confirming compliance with the legal emission limits. In case of failure, the vehicle owner is advised on necessary repairs before retesting.
