Petrol in the context of "Internal combustion engine"

North American English (NAmE) encompasses the English language as spoken in both the United States and Canada. Because of their related histories and cultures, plus the similarities between the pronunciations (accents), vocabulary, and grammar of U.S. English and Canadian English, linguists often group the two together. Canadians are generally tolerant of both British and American spellings, although certain words always take British spellings (e.g., cheque rather than check) and others American spellings (e.g., tire rather than tyre).

Dialects of English spoken by United Empire Loyalists who fled the American Revolution (1775–1783) have had a large influence on Canadian English from its early roots. Some terms in North American English are used almost exclusively in Canada and the United States (for example, the terms diaper and gasoline are widely used instead of nappy and petrol). Although many English speakers from outside North America regard those terms as distinct Americanisms, they are just as common in Canada, mainly due to the effects of heavy cross-border trade and cultural penetration by the American mass media. The list of divergent words becomes longer if considering regional Canadian dialects, especially as spoken in the Atlantic provinces and parts of Vancouver Island where significant pockets of British culture still remain.

A filling station (also known as a gas station [US] or petrol station [UK/AU]) is a facility that sells fuel and engine lubricants for motor vehicles. It serves as a local fuel depot and retailer who receive fuel products from refineries (via regular tank truck resupplies), keep the fuels in (typically underground) storage tanks, and distribute individual product to motorist consumers at a daily varied price.

The most common fuels sold are motor fuels such as gasoline (a.k.a. petrol, often as multiple products according to different octane ratings) and diesel fuel, as well as liquified petroleum gas (LPG, i.e. autogas), compressed natural gas, compressed hydrogen, hydrogen compressed natural gas, liquid hydrogen, kerosene, alcohol fuels (like methanol, ethanol, butanol, and propanol), biofuels (like straight vegetable oil and biodiesel), or other types of alternative fuels. Fuel dispensers are used to pump fuel into the fuel tanks within vehicles, gauge the volume of fuel transferred to the vehicle, and calculate the financial cost the consumer must pay. Besides fuel pumps, another significant device found in filling stations and capable of refueling certain (compressed-air) vehicles is an air compressor. However, these are generally used to inflate car tires.

Petroleum transport is the transportation of petroleum and derivatives such as gasoline (petrol). Petroleum products are transported via rail cars, trucks, tanker vessels, and pipeline networks. The method used to move the petroleum products depends on the volume that is being moved and its destination. Land-based transportation modes such as pipelines and rail each have strengths and weaknesses.  One of the key differences is the cost associated with transporting petroleum though pipeline or rail. The Very toxic with moving petroleum products are pollution related and the chance of spillage. Petroleum oil is very hard to clean up and is very toxic to living animals and their surroundings.

Petroleum naphtha is an intermediate hydrocarbon liquid stream derived from the refining of crude oil with CAS-no 64742-48-9. It is most usually desulfurized and then catalytically reformed, which rearranges or restructures the hydrocarbon molecules in the naphtha as well as breaking some of the molecules into smaller molecules to produce a high-octane component of gasoline (or petrol).

There are hundreds of different petroleum crude oil sources worldwide and each crude oil has its own unique composition or assay. There are also hundreds of petroleum refineries worldwide and each of them is designed to process either a specific crude oil or specific types of crude oils. Naphtha is a general term as each refinery produces its own naphthas with their own unique initial and final boiling points and other physical and compositional characteristics.

There are a wide variety of propulsion systems available or potentially available for automobiles and other vehicles. Options included internal combustion engines fueled by petrol, diesel, propane, or natural gas; hybrid vehicles, plug-in hybrids, fuel cell vehicles fueled by hydrogen and all electric cars. Fueled vehicles seem to have the advantage due to the limited range and high cost of batteries. Some options required construction of a network of fueling or charging stations. With no compelling advantage for any particular option, car makers pursued parallel development tracks using a variety of options. Reducing the weight of vehicles was one strategy being employed.

A petrol engine (gasoline engine in American and Canadian English) is an internal combustion engine designed to run on petrol (gasoline). Petrol engines can often be adapted to also run on fuels such as liquefied petroleum gas and ethanol blends (such as E10 and E85). They may be designed to run on petrol with a higher octane rating, as sold at petrol stations.

Most petrol engines use spark ignition, unlike diesel engines which run on diesel fuel and typically use compression ignition. Another key difference to diesel engines is that petrol engines typically have a lower compression ratio.

Sour crude oil is crude oil containing more than 0.5% sulfur impurities (by weight). The impurities need to be removed before this lower-quality crude can be refined into petrol, thereby increasing the cost of processing. This results in a higher-priced gasoline than that made from sweet crude oil.

Current environmental regulations in the United States strictly limit the sulfur content in refined fuels such as diesel and gasoline.
