Record 1 2017-03-29

English

Subject field(s)
  • Chemical Elements and Compounds
  • Pollutants
DEF

An organic compound of hydrogen and carbon, whose density, boiling point, and freezing point increase as their molecular weight increases.

OBS

Four hydrocarbons are contributing to the global warming: methane (CH4) is a key greenhouse gas; ethane (C2H6), propane (C3H8) and acetylene (C2H2 are lesser greenhouse gases.

OBS

hydrocarbon; HC : term and abbreviation standardized by Environment Canada and the Translation Bureau for use in the Black Carbon Inventory and the Air Pollutant Emission Inventory Report.

OBS

hydrocarbon; HC: term and abbreviation officially approved by the Lexicon Project Committee (New Brunswick).

French

Domaine(s)
  • Éléments et composés chimiques
  • Agents de pollution
DEF

Composé organique ne contenant que du carbone et de l'hydrogène.

OBS

Les hydrocarbures contribuent largement au réchauffement climatique. Le méthane, après le dioxyde de carbone, est le principal gaz à effet de serre. Mentionnons également le propane, l'éthane et l'acétylène.

OBS

hydrocarbure; HC : terme et abréviation normalisés par Environnement Canada et le Bureau de la traduction dans le cadre de l'inventaire de carbone noir et de l'Inventaire des émissions de polluants atmosphériques.

OBS

hydrocarbure : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

Spanish

Campo(s) temático(s)
  • Elementos y compuestos químicos
  • Agentes contaminantes
DEF

Compuesto orgánico consistente exclusivamente en elementos de carbono e hidrógeno.

CONT

Las combinaciones del carbono con el hidrógeno son muy numerosas, variadas e importantes. Ciertos hidrocarburos son gaseosos, como el metano; otros son líquidos, como el benceno, y otros sólidos, cual el naftaleno.

CONT

Los CFC [clorofluorocarburos] y HCFC [hidroclorofluorocarburos] son compuestos derivados de los hidrocarburos [...] por sustitución de todos o algunos de sus átomos de hidrógeno con átomos de cloro y de flúor.

OBS

Se obtiene principalmente del petróleo, del alquitrán de hulla y de fuentes vegetales.

Record 2 2014-07-04

English

Subject field(s)
  • Biochemistry
  • Biomass Energy
CONT

As a result of studies made with rapeseed oil, researchers reported that rapeseed oil methyl esters can be used on diesel engines. It was determined that rapeseed oil methyl ester showed better results than soybean oil methyl ester in terms of emission. In addition, with pre-heating application, the engine torque increased at low engine speeds, CO, HC and smoke density decreased significantly. It was determined that using of rapeseed oil methyl ester shortened the ignition delay period.

French

Domaine(s)
  • Biochimie
  • Énergie de la biomasse
CONT

L’ester méthylique de colza, qui dans un premier temps a été développé pour des raisons d’indépendance de carburant en cas de choc pétrolier, s’est peu à peu affirmé comme un carburant alternatif au gazole, notamment pour une utilisation sur les flottes captives (les bus par exemples). Après une baisse de l’utilisation due au développement de nouveaux moteurs fonctionnant avec du gazole désulfuré, l’ester a retrouvé un nouveau souffle de vie en tant qu’«additif de luxe».

Record 3 1986-01-06

English

Subject field(s)
  • Environmental Studies and Analyses
CONT

The projected emissions of CO [carbon monoxides], NOx [nitrogen oxides], and HC [hydrocarbons], from the transportation sector until the end of the century are based on two scenarios :.... In calculating the status quo projections for the transportation sector, the following assumptions were made :... emissions from other transportation sources are based on a fuel usage forecast prepared by the Department of Energy, Mines and Resources, and trend analysis of historical emission data developed by Environment Canada.

Record 4 1985-12-09

English

Subject field(s)
  • Types of Motor Vehicles and Bicycles
OBS

LDT= light duty truck (cf. EN-49-1-2-5, 1984, p. 14E).

OBS

... [plur.] gasoline-engined LDTs ....

CONT

Of the proposed changes considered in this study, adoption of 1. 05 HC, 11. 16 CO, and 1. 43 NOx g/km standards for light-duty trucks would have the least impact. Most manufacturers already use the same or a recalibrated version of the U. S. federal truck emission control systems for gasoline-engine LDTs and would use these systems to comply.
