BTU is an abbreviation for British Thermal Unit. This represents how much heat or energy is required to increase the temperature of 1 lb of water by 1 degree Fahrenheit. Gasoline, on average, creates between 115,000 and 125,000 BTUs. In contrast, ethanol creates about 75,000 BTUs.

yes, to English people it's known as petrol and to countries such as America it's known as gasoline, so to answer your question yes they are the same :)
The gasoline engine was needed because the steam engine was too large and heavy for anything smaller than a train or a large boat. Everyone was trying to invent a smaller, lighter power source.

Complexity and expense
For regular gasoline, 125,000 BTU per US gallon
In a gallon of gasoline, there is approximately 124,884 btu. BTU refers to British thermal unit. It is actually a traditional unit.
No, the BTU (British Thermal Unit) value of gasoline does not increase if the temperature decreases. The BTU value of gasoline is a measure of its energy content and is not affected by temperature changes.
Yes. Kerosene has 140,000 btu's per gallon and gasoline has less.
Gasoline has a btu rating of around 110,000. Ethanol has a btu rating of around 76,000.
In a word, No... The energy content stays the same.
The internal combustion engine converts heat to motion or kinetic energy. Since ethanol has less "heat" than gasoline per gallon the fuel mileage will be less. Heat content of conventional gasoline = 115,500 Btu/gallon Heat content of ethanol = 76,000 Btu/gallon E85 is a blend of 15% gasoline and 85% ethanol so you can expect a drop in MPG of 20% or more.
Check this website out. It has a list of all fuels and the BTU outputs. http://www.cogeneration.net/FuelAndEnergyConversionandEquivalence.htm
In general, yes. The diesel engine cycle utilizes much higher compression than a gas engine. And the higher the compression, the more "efficient" the engine- everything else being equal. Also, diesel has more energy (btu) per gallon that gasoline, so you win on two fronts.
a gasoline engine is an Internal combustion engine
Gasoline can generate roughly 20K BTU/lbm. There are 6 lbm per US gallon.
The BTU (British Thermal Unit) content of gasoline can vary slightly based on formulation and additives, but generally, 87 octane unleaded gasoline contains about 114,000 BTUs per gallon. E10 blends (like 87E10 and 89E10, which contain 10% ethanol) typically have a slightly lower BTU content, around 111,000 BTUs per gallon due to the ethanol. Premium gasoline (91 octane) generally has a similar BTU content to regular unleaded, around 113,000 to 114,000 BTUs per gallon.
