Is your car secretly contributing to climate change and costing you money? Many drivers are unaware of the hidden emissions their vehicles produce, silently polluting the environment and draining their wallets. These emissions aren’t just a threat to the planet—they’re also a sign that your vehicle might not be running as efficiently as it should. Emission tests can uncover a range of underlying issues, helping you catch problems early and avoid expensive repairs down the road.
More Greenhouse Gases = More Money Lost?
Road transport is a major source of pollutants, including particulate matter (PM 10 or less), nitrogen dioxide (NO2), and ground-level ozone. These pollutants harm health—causing respiratory issues—and contribute to greenhouse gases like CO2, CH4, and NO, NO2, in particular, is an irritant that can damage cell membranes and proteins, leading to respiratory problems and even cancers. Its levels have risen due to higher NOx emissions from diesel vehicles. Higher greenhouse gas emissions can signal underlying mechanical issues. Increased CO2 often indicates the engine is burning excess fuel due to faulty oxygen sensors, a clogged injector, or a malfunctioning catalytic converter. Similarly, elevated levels of methane (CH4) or nitrous oxide (N2O) suggest incomplete combustion, often from poor maintenance or issues with emissions control systems like the exhaust gas recirculation (EGR) system or Diesel Particulate Filter (DPF). These gases not only impact climate change but also lead to inefficiencies that can result in costly repairs.
In Australia, emissions compliance often relies on manufacturers’ claims, unlike in Europe, where vehicles undergo annual rigorous testing throughout their lifespan. However, factors like vehicle condition, service history, fuel quality, and usage can affect emissions levels, meaning real-world emissions often differ from manufacturers’ standardised results. As a workshop professional, monitoring these variables is key to providing top-tier service and helping clients avoid costly issues down the road.
As a workshop owner, these signs shouldn’t be ignored. Regular emissions testing and maintenance are essential to catch these issues early, ensuring the vehicle runs efficiently, meets emissions standards, and saves your clients money. Informing clients about these potential problems and addressing them can improve vehicle performance while reducing environmental impact.
So, What’s Emission Testing and How Does It Work?
Emission testing measures pollutants like CO2, hydrocarbons, and nitrous oxides emitted by your vehicle. The purpose is to ensure vehicles aren’t releasing harmful pollutants that contribute to air pollution and health issues. The test also helps identify vehicles that aren’t operating efficiently, which can result in increased fuel consumption and emissions.
Once connected to the vehicle, the diagnostic device measures emissions while the engine runs, comparing the data to state or national standards to determine if the vehicle passes.
How to Prepare for an Emissions Test
- Maintain Regularly: Keep the engine, fuel system, and emissions control system in good condition. Change oil and air filters, replace worn spark plugs, and keep the fuel system clean.
- Warm Up the Vehicle: Drive for at least 20 minutes before the test to warm up the engine and catalytic converter.
- Check Engine Light: Ensure the check engine light is off by fixing any detected issues.
- Check Fuel Level and Battery: Ensure the fuel tank is at least a quarter full, and the battery is fully charged for accurate readings.
If the vehicle fails the test, repairs may be needed. Using quality fuel, driving efficiently, and replacing faulty components like the oxygen sensor or catalytic converter are crucial for a successful retest. Following these guidelines helps reduce pollution and maintain vehicle efficiency.
