High Hydrocarbon (HC) emissions are almost always a sign of poor fuel ignition. Hydrocarbons are basically raw fuel. PPM (parts-per-million) is a way of quantifying small concentrations.

What does ppm mean relating to an emissions test?
Parts Per Million.
How ppm is used in cars?
In measuring exhaust emissions.
Can new spark plug increase hc emissions?
not really.new spark plugs should help to decrease hc emissions hc emisions are caused by unburnt fuel which is usually caused by faulty spark plugs or faults in the ignition system which would cause the engine to misfire creating a rich mixture ie high hc (hydrocarbons)
What is Indolene?
Indolene is a form of gasoline used in testing because it is standardized and has no additives. Indolene gasoline is used for the US Federal Test Procedure (FTP) to certify vehicles for emissions rather than commercial gasoline. Indolene fuel used in certification typically has a sulfur content below 50 parts per million (ppm). On the other hand, commercial gasoline sulfur content ranges between 30 and 1000 ppm throughout the US with an average of about 300+/-50 ppm. Indolene gasoline results in reproducible tailpipe emissions from a test vehicle. Commercial gasoline results in a wide range of emissions. The emissions differences are attributable largely to the disparity in gasoline sulfur content. source: http://www.meca.org/galleries/default-file/sulfur.pdf http://www.futurefueltechnologies.com/?page_id=42
What emissions gases is converter with in the catalytic converter?
HC hydrocarbons CO carbon monoxide NOx oxides of nitrogen
What exhaust emissions do catalytic converters reduce?
Hydro carbons, oxides of nitrogen and carbon monoxide. HC, NOx, and CO
How much have the world's CO2 level risen in a decade?
In 2003 carbon dioxide emissions were 370 ppm (parts per million). This year (2013) they reached 400 ppm. At the beginning of the Industrial Revolution they had been 280 ppm for thousands of years.
What is the purpose of a catalytic converter?
To lower the amount of harmful emissions in the exhaust. It converts HC, CO and NOx into H20, CO2, and N2.
On the California smog emission test what does HC stand for?
It stands for hydrocarbons
You did smog and if fail the HC PPM what should you do?
The check engine light must be on. Start with having the codes read. Your local auto parts store will help you with that at no cost.
What is HC ppm?
it's hydro carbons parts per million.. its a way of measuring you engine emmissions and if the car is running "clean" enough to be given an inspection sticker...
Was there a recall on the 1988 dodge dynasty?
The only recall I found was: 181 3.0 SOHC engine: 12/93 Excessive HC emissions
