What else can I help you with?
What causes high CO readings in auto emissions test results?
High CO is a rich air/fuel mixture. Nothing else.
What element are fossil fuels rich in?
Fossil fuels are rich in carbon, which is a key component that gets released when they are burned. This carbon-rich content is what contributes to the greenhouse gas emissions associated with fossil fuel combustion.
What filter should you use to reduce carbon monoxide emissions?
carbon monoxide is a rich indicator, if you are producing too much, you have a fuel system problem.
What is mean by air fuel ratio?
the ratio of the amount (mass) of air to fuel. Ideal is 14.7 lbs of air to 1 lb of fuel to completely burn air the fuel. A slightly rich raitio of about 12.5:1 car produce more power at the expense of emissions.
What is the difference between lean burn and rich burn with regards to gas turbines?
Lean burn refers to operating a gas turbine with excess air to optimize fuel efficiency and reduce emissions, while rich burn involves adding more fuel to the combustion process to increase power output. Lean burn technology is typically used for low emissions and increased efficiency, while rich burn is used for higher power output and faster response times.
Why does a 1991 Honda Civic LX exhaust smell like rotten eggs?
Malfunctioning emissions system. Get this repaired. Engine probably running rich from a leaking fuel pressure regulator. If there is fuel in the vacuum line the regulator is bad.
1993 vortec 4.3 runs rich?
Need to check fuel pressure regulator, and it could be the MAP sensor making it run rich. Is the check engine light on???? If it is have engine scaned with engine scanner so you can read the codes, and see what is going on with the emissions.
Why is your Ford Freestar burning rich?
If your Ford Freestar is burning rich, it could be due to several factors, including a malfunctioning mass air flow sensor, a faulty oxygen sensor, or a defective fuel pressure regulator. Additionally, issues with the fuel injectors or a clogged air filter can contribute to an improper air-fuel mixture. It's essential to diagnose the issue accurately, as running rich can lead to reduced fuel economy and increased emissions. Regular maintenance and timely repairs can help prevent these problems.
What cause unburned gas?
Unburned gas can be caused by factors like a fuel mixture that is too rich, a problem with the ignition system that prevents complete combustion, or a malfunctioning exhaust system that does not properly expel exhaust gases. This can lead to decreased fuel efficiency and increased emissions.
Why won't a 1992 Chevy Cavalier pass smog excessive fuel consumption running too rich 1300 instead of 100 what should be checked?
Oxygen sensor. Fuel-to-air ratio should be 14 to 1.
What happens to a vehicle if the OH2 censor happens to be cut and how long would the damage take if any?
If you mean the HO2 (Heated Oxygen Sensor), then that works to tell your car's ECM how rich or lean the engine is running. The ECM uses that information to adjust the fuel ratio to keep the engine's emissions to a minimum. If the Oxygen Senor is not functioning, the ECM cannot tell what the engine is doing and goes to a default, rich fuel mixture. An overly rich mixture will decrease you vehicle's fuel economy and cause damage to your catalytic converter.
How to fix code p1441 on Chevy tahoe?
general consensus that the PURGE VALVE SOLENOID is to blame. Of course it is an emission control nonsense....but nevertheless, needs to be resolved to pass emissions and to keep the SES light off. Some of my research states that fuel economy will suffer as it can pose a RICH running condition. I'm not certain if that is indeed correct, these vehicles are not known for great economy.
