Causes

Effects

the catalyst systemleadingto higher exhaust emissions over the lifetime of the engine

The result is less than complete combustion of the gasoline fuelleadingto increase engine - out hydrocarbon emissions

an emissions related problemmight causethe engine to produce excessive emissions

as excess oil here would contaminate the mixtureleadingto excess oil being burned in the engine and so excessive hydrocarbon emissions

electric cars end upcausingas many emissions as petrol engines

fluctuating coolant temperaturescould leadto higher engine out emissions

orderto provokea desired increase in the emissions of hydrocarbons

oil changes ... the old , dirty oilcan leadto excessive engine emissions

This experiencehas resultedin engines with very low emissions of hydrocarbons

even a perfectly clean and undamaged plugcan causehigh hydrocarbon emissions at start - up

the old , dirty oilcan leadto excessive engine emissions

this technologyleadsto vastly reduced emissions from engines

Old and dirty oilcausesan excess of noxious engine emissions

Older cars and trucks sometimes burn old , dirty oilcausingan excess of noxious engine emissions

those gradesare ... designedfor low emissions engines

chances ... that happento be designedto cut down emissions from your engine

fuel ... which is believedto contributeto engine - out soot emissions

which is believedto contributeto engine - out soot emissions

of coursewill resultin high hydrocarbon emissions

Thus , the accuracy of the sensor may be degradedleadingto degraded engine emissions

airleadingto higher emission of hydrocarbons

engines run leanerleadingto lower hydrocarbon emissions

fuel system pressure and injection sensorsmay contributeto engine - out emissions

the use of storage tankswere causingemissions of hydrocarbons into the atmosphere

several factors(passive) can be influenced byThe emissions from an engine

Any lower excess oxygen levelwould leadto excessive unburned hydrocarbon emissions

evaporateresultingin excessive emissions of hydrocarbons

the increasing temperaturesleadingto increases in emissions of hydrocarbons
