Diesel and petrol engines work differently. Diesel engines use compression to ignite the air/fuel mixture, and have a much higher compression ratio than petrol engines, which use spark ignition. The conditions for ignition are not met when petrol is put into a diesel engine, and will stall.
Diesel is not considered environmentally friendly because it emits more pollutants like nitrogen oxides and particulate matter compared to gasoline. These emissions can contribute to air pollution and have negative impacts on human health and the environment.
Petrol is more efficient as a fuel than ethanol, because the energy generated by burning a fuel is primarily released by formation of bonds between oxygen and carbon or hydrogen. One such bond already exists in an ethanol molecule, whereas in petrol few or no such bonds exist.
There is not a clear cutoff point between "high and Low sulfur diesel". Ultra low sulfur diesel ULSD is what is currently required for on road use. ULSD can contain no more than 15 ppm sulfur (15 micrograms sulfur per gram of fuel or 0.0015 wt.%). Low sulfur diesel would contain more sulfur than ULSD and high sulfur diesel more than low sulfur diesel.
Petrol, also known as gasoline, does not have a single freezing point as it is a mixture of hydrocarbons. However, the components of petrol typically begin to solidify at temperatures below -40°C (-40°F).
CO2 is inevitably created by burning fuels like e.g. oil, natural gas, diesel, organic-diesel, petrol, organic-petrol, ethanol. The emissions of CO2 have been dramatically increased within the last 50 years and are still increasing by almost 3% each year, see graph below:
Overall each piece is bigger and heavier.
Due to the increase in the compression ratio of a diesel which fires on compression rather than spark, the engine is built much stronger than a petrol engine. It therefore just costs more to manufacture.
The primary difference between a petrol car and diesel car is the consumption rate - diesel and petrol are refined from mineral oil using differing methods. The result is diesel engines having a lower fuel consumption rate than their petrol counterparts when installed in a vehicle of similar mass. CO2 emissions are also lower in a diesel engine than they are in a petrol engine.
In the United States diesel is not cheaper than petrol or gasoline, it is higher.
No, diesel is heavier.
The burning temperature of diesel is higher than that of petrol. Diesel ignites at a higher temperature compared to petrol.
Petrol is and bit more vicous and that diesel is a lot darker than petrol. Petrol burns quicker when set alight, however diesel burns more brightly!
because petrol is easer to burn than diesel
The difference is that diesel is more oily than petrol, and is cheaper to produce.
Depends on the car, if a car has petrol and diesel version than yes
first of all its engine. ADVANTAGES - petrol is cheaper than diesel so cheaper to run. petrol cars generally cost less than diesel (a few 1000). petrol engines are usually faster than diesel off the line and have a higher top speed than a diesel car with the same sized engine. DISADVANTAGES - petrol is less economical than diesel and also diesel cars are much better for over taking than petrol as it has more torque (pulling power)
diesel is usually more expensive but diesel cars usually have more mpg than petrol cars
