How can I reduce the emissions on my diesel car?
An excellent way to reduce diesel emissions is to install a selective catalytic reduction (SCR) onto your car. The job of the SCR is to convert gases from NoX to either nitrogen or water vapour. This advanced emissions control technology system adds ammonia to the exhaust gases.
What does HC ppm mean?
Find “HC PPM” within the tailpipe section. You read this as hydrocarbon parts per million, and it means the number of hydrocarbon molecules for every million molecules emitted through the exhaust.
How do you cheat emissions?
6 Proven Methods for Passing an Emissions (Smog) Test:
- Test a very warm car on a cool day.
- Use a specialized fuel additive.
- Inflate tires to the proper (high) level.
- Perform an oil change.
- Turn off your “Check Engine” light (if needed).
- Find a shop that offers a free retest.
How do I check my exhaust emissions?
A probe is placed in the tailpipe of the car and the exhaust gases are measured following a strict procedure. The exhaust gas analyser is used for measuring 4 gases, oxygen (O2), carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbons (HC) as well as calculating lambda (λ) a measure of air/fuel ratio.
What does emissions test check for?
Depending on the testing apparatus, emissions testing can detect levels of hydrocarbons, nitrogen oxide, carbon monoxide, carbon dioxide, and emissions from evaporation. Is Emissions Testing The Same As Vehicle Safety Inspection? Emissions testing is separate from vehicle safety inspection in most states.
What causes a high hydrocarbon reading during a smog test?
In the state of Connecticut, 150 parts per million is the maximum reading required to pass a smog test. The danger in hydrocarbon emission is in its combination with sunlight and nitrogen, which forms ozone. Ignition timing issues may cause a failed smog test, either through a functional failure or through increased release of hydrocarbons.
What causes a high HC reading on an emissions test?
Let’s start by understanding what things cause a high HC reading. A high HC reading means the test found high HC (hydrocarbons) in your emissions. In other words, too much gas is left in the exhaust after combustion.
What causes a failed smog test in California?
Hydrocarbon Emissions. Emissions are measured in parts per million, or ppm, and a higher release of hydrocarbons from a vehicle can cause a failed smog test. For example, in the state of California, the maximum hydrocarbon parts per million is 64 when the test is run at a simulated 15 miles per hour.
What can be done about high NOx in smog?
The solution to this problem is called De-Carbonizing. It usually costs around two labor hours at a smog check repair station. It will remove a good amount of carbon out of an engine. This will increase combustion space, lower compression and lower NOx. 5. Engine Overheating – Inadequate engine cooling can will high NOx.
