My theory about this is that you can get waaaaaaay more miles per gallon on one tank of diesel compared to a petrol engine so that means you fill up less so petroleum distrabutors put the prices up because you will be using their services less.
Diesel engine runs at a higher compression ratio than a gasoline engine. A typical diesel engine may also use a longer stroke and smaller bore than a gasoline engine. Diesel fuel has a higher energy density than gasoline.
In the United States diesel is not cheaper than petrol or gasoline, it is higher.
Diesel fuel is usually expensive than gasoline because, diesel undergoes many expensive processes in the refinery than gasoline.
Higher than a gasoline engine.
Normally Diesel engines produce more torque than gasoline engines but less horsepower. Gasoline engines rev up quicker and produce higher horsepower at higher rpms. Diesel engines develop their higher torque at lower rpms which allows a diesel to carry a heavier load.
Because of a diesel engines high compression ratio, it will always be more efficient than an equivalent gasoline engine. However, this higher compression ratio requires a heavier, more expensive engine which isn't able to reach as high an RPM as a gasoline engine. It is for these reasons that despite their higher efficiencies, diesel engines are less popular than their lighter, less expensive gasoline equivalents. Diesel cars will provide you with a higher MPG rating compared to a similar gasoline powered engine. The price for diesel fuel is generally higher than the cost of unleaded gasoline.
Diesel fuel is the kind of fuel used by diesel engines. Its a combustible fuel refined from crude oil - just as is gasoline - but diesel has a much higher flash point than gasoline. Its grade is measured in cetane rather than octane
The flash point difference between diesel and gasoline is that diesel has a higher flash point than gasoline. Diesel typically has a flash point of around 125-180 degrees Celsius, while gasoline has a flash point of around -40 to -60 degrees Celsius.
Diesel gas is a type of fuel commonly used in diesel engines. It is different from regular gasoline in terms of how it is ignited and its chemical composition. Diesel fuel is ignited by compression rather than a spark, and it contains higher energy density and lower volatility compared to gasoline.
Both are petroleum products but gasoline is refined further than diesel is.
The advantage of a diesel truck is that diesel burns more efficiently than regular gasoline. However, parts and service for a diesel truck are sometimes higher.
Diesel engines have a much higher compression ratio than gasoline engines. Therefore, you need to drain all the fuel you can out of your tank and fill it with diesel. Gas in a diesel engine will go boom, and destroy your engine.
