If it's injected, run a diag test. A basic tune-up should help with more complete combustion. Plugs, wires, rotor and cap along with setting the timing. Also, make sure the air filter is clean. Replace it if there is any question. If you're getting too much fuel it could be ther air filter, if it's just not all burning it could be the ignition.

What is a cat converter?

Catalytic converter. A device that use platinum as a catalyst to reduce unburned hydrocarbon emissions from your vehicles exhaust.

What a catalytic converter?

Mounted in exhaust system down stream from engine it reburns unburned gases. Object, cleaner emissions.

What emission comes from a car's exhaust?

The emissions are mainly nitrogen, carbon dioxide, NOx, water vapour and unburned hydrocarbons

Purpose of catalytic converter?

It superheats exhaust gases and burns any unburned gases to clean up the emissions escaping from the tailpipe.

What is an EGR valve what does it do?

EGR (exhaust gas reclaimer), it is designed to reburn unburned exhaust gases. It helps clean up emissions.

What happens if you take the catalytic converter off?

Your car's unburned hydrocarbon emissions will rise. In many states this is illegal and you can be severely fined.

How do you spell cataliticenverter?

A catalytic converter is an automotive emissions device that uses heated metal compounds (notably platinum) to remove unburned fuel from exhaust gases.

What are some ways you can cut back on household causes for carbon emissions?

You can always use green energy resources. You can check your smoke before emitting it.

How does a converter overcome unburned hydrocarbons?

This question refers to the emissions control equipment used on modern vehicles. A vehicles catalytic converter may used platinum and palladium substrates to bind with CO and NOx to change them into ideally water, carbon dioxide, nitrogen and oxygen only emissions.

Can you get a dirty urine by smelling unburned weed?

No, unburned weed does not smell like that.

Why is led called led?

because it is a Light Emitting Diode

How does the secondary air injection system work?

An air pump pumps in fresh air into the exhaust system before the catalytic converter to help the cat converter burn unburned fuel = cleaner emissions.

What damage does the erg valve do?

Perhaps you mean EGR valve. It stands for exhaust gas reclaimer. It sends some of the exhaust back through the engine to re-burn unburned fumes for cleaner emissions.

Can one get sick from exhaust fumes from a propane powered fork lift?

Possibly. If your LPG motor is emitting those kind of fumes it is needing repair. They are noted for low emissions.

2 ways to minimize air pollution?

2 general ways are to avoid emitting things that will be pollutants and promoting things, like trees, that will help remove pollutants. To avoid emitting pollutants you can optimize processes to have lower emissions of everything including pollutants, remove the pollutants before releasing (like filters and scrubbing towers), process the emissions to change them (like catalytic converters), change to processes that do not emit pollutants.

LED stands for Light-Emitting?

LED stands for Light-Emitting Diode.

Why are elements that break apart called unstable?

because in the process of emitting alpha rays they become stable or change into other elements by emitting gamma particles.

Why is your emissions control light on in your 2005 Tahoe?

because your emissions need controlling, pretty basic stuff here

Why is Hephaestus still relevant?

Is it because Mt Etna is still emitting smoke?

What can Light Emitting Diodes be used for?

Emitting light!

Information about types of fuels used for cooking?

Fuels burned for cooking are usually burned in conditions of plentiful air and low temperatures so the production of CO and NOx is low. Burning of biomass can create organic emissions as volatiles are boiled out of the unburned material. Carbon dioxide emissions are lowest with methane and highest with coal, peat and charcoal.

Why is it necessary to use sustainable energy options?

Because fossil fuels are not infinite, they will eventually be used up and we shall have to use alternatives. Also we want to reduce emissions of CO2, so it's best to try to use sustainable non CO2 emitting fuels to a greater extent.

What if there is unburned gasoline in your engine?

The unburned gasoline accumulated in the crankcase is recirculated by the PCV valve to the intake air and burned again. The unburned gasoline in the exhaust reacts inside the catalytic converter, making carbon dioxide and water.

How can you generate energy without emitting greenhouse gases?

Using renewable energy sources like solar, wind, hydro, tide and wave power, geothermal and biofuel releases no carbon dioxide emissions.

What does emissions mean?

Things like cars. Look at 'what is the government doing about global warming?' It's me answering To make it more clear, it's the act of throwing something out. Emitting can refer to Science a lot of the time, such as the emission of an alpha particle from a nucleus or the sun emitting heat and light. For global warming, pollution is being emitted in the air.
