If it’s really cold, using adiesel block heaterovernight (when available) is a far better option than trying to warm the engine by idling it. And while we’re on the topic, can wepuh-LEASE,for once and for all, bring an end to the practice of leaving engines (dieselorgasoline) id...
aThe demand for lighter products, such as Gasoline, Kerosene and Diesel is much higher than the demand for heavier products 对更轻的产品的需求,例如汽油、煤油和柴油对更重的产品的需求高于[translate]
Fuel with an octane rating of 87 is less resistant to detonation than fuel with a rating of 89 or 91.A gasoline's octane rating can be improved by additional refining to increase the proportion of heavier hydrocarbons in the fuel, by using a higher grade crude stock or by adding ethanol ...
What component of gasoline gives it such a high enthalpy of combustion? a. hydrocarbons b. hydrogen c. carbon d. magnesium e. none of the above What mass of carbon dioxide is formed by the complete combustion of 760 g of ethanol? The harmful exhaust emission ...
Ethanol is commonly used as a gasoline supplement, but it is currently about twice as expensive as methanol, the low price of which is one of its attractive features. Methanol"s most attractive feature, however, is that it can reduce by about 90 percent the vehicle emissions that form ozone...
If the solid form of most molecules is heavier than the liquid form, why does ice float? a. Water molecules are arranged farther apart when frozen than in liquid form. b. A water molecule is larger in the liquid state than in the solid state. c. The cryst Why sodium oxide is ...
gasoline with cleaner-burning fuelssuch as compressed natural gas, liquefied petroleum gas, ethanol, or methanol.All of these altematives are carbon-based fuels whose molecules are smaller and simpler than those of gasoline.These molecules burn more cleanly than gasoline, in part because they have ...
Gasoline Engines: With the invention of the internal combustion engine, and the advent of gasoline automobiles in 1885 by Karl Benz, petroleum soon became a sought after energy source. Electricity: With the perfection of the electric light in 1879, Thomas Edison had enlightened the world. However...

heavier oligomers (typically the C10 or C11+ molecules, except for the tetramer (mainly C12) that is made from propylene), and the molecules that are not directly made by oligomerisation of fresh feed olefins, but made via a mechanism involving cracking to other than those fresh feed olefins...
