forceful or intense; dynamic; high-powered: high-octane efforts to obliterate the competition.
What octane means?
Octane rating is the measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. In the U.S., unleaded gasoline typically has octane ratings of 87 (regular), 88–90 (midgrade), and 91–94 (premium).
Which is better high octane or low octane?
Low-octane fuels are formulated to burn or combust faster and more easily. High-octane fuels, on the other hand, are designed to burn more slowly and more evenly. The difference is that the low-octane fuels have a greater tendency for pre-ignition (knock or ping) since they burn quickly.
What is meant by high octane petrol?
An octane rating, or octane number, is a standard measure of a fuel’s ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating.
What is another name for octane?
What is another word for octane?
| n-octane | 2,2,3,3-tetramethylbutane |
|---|---|
| 2-methylheptane | 3,3-dimethylhexane |
| 3,4-dimethylhexane | 3-ethyl-2-methylpentane |
| 3-ethyl-3-methylpentane | 3-ethylhexane |
| 3-methylheptane | 4-methylheptane |
What does low octane mean?
Lower-octane gas (like “regular” 87-octane gasoline) can handle the least amount of compression before igniting. The compression ratio of your engine determines the octane rating of the gas you must use in the car.
Why is it called octane?
The name “octane” comes from the following fact: When you take crude oil and “crack” it in a refinery, you end up getting hydrocarbon chains of different lengths. These different chain lengths can then be separated from each other and blended to form different fuels.
Is high octane good?
Higher octane allows engines to have higher compression ratios (for a more energetic explosion), more advanced ignition timing or forced-air induction like turbochargers or superchargers. They perform best when fed premium fuel.
How is octane made?
Herman Kolbe (1818-1884) found that alkanes can be made by electrolysis of salts of carboxylic acids. So using sodium pentanoate results in octane (and carbon dioxide) at the anode – and sodium hydroxide and hydrogen at the cathode. Two butyl groups get coupled together to make the octane molecule in this reaction.
What is the synonym of often?
oft, oftentimes. (or ofttimes), over and over, repeatedly.
