diesel
The burning temperature of diesel is higher than that of petrol. Diesel ignites at a higher temperature compared to petrol.
In the United States diesel is not cheaper than petrol or gasoline, it is higher.
Diesel fuel produces more energy per liter compared to petrol (gasoline). This is primarily due to its higher energy density and the fact that diesel engines operate at a higher compression ratio, making them more efficient. On average, diesel contains about 10-15% more energy than petrol, which contributes to better fuel economy in diesel engines.
The density of petroleum diesel is about 0.85 kg/l whereas petrol (gasoline) has a density of about 0.72 kg/l, about 15% less
Fuel oil is thicker than petrol because it has a higher viscosity and density. Fuel oil is used in heating systems and diesel engines, while petrol is used as a fuel for gasoline engines in cars.
No, the density of petrol is lower than the density of water. Water has a density of 1 g/cm³, while the density of petrol is around 0.75-0.85 g/cm³.
Diesel fuel and petrol/gasoline are similar; both of them are mainly mixtures of hydrocarbons. However, Diesel is considerably less volatile because it the compounds in it are of higher molecular weight; they have a higher boiling point ... and also a higher freezing point.
No. I'm not sure of the exact numbers. Petrol will boil off of your hand, while Diesel will not. Try it if you get the chance.
Diesel engines operate at higher temperatures than petrol engines primarily due to their higher compression ratios. The diesel combustion process relies on compression ignition, which generates more heat as air is compressed before fuel is injected. Additionally, diesel fuel has a higher energy density and requires more heat to ignite compared to petrol, contributing to the overall higher combustion temperatures in diesel engines. These factors result in more efficient energy conversion but also mean that diesel engines typically run hotter.
Diesel has a much higher viscosity than petrol (gasoline). It is less refined and contains more oil to lubricate and cool the combustion chamber in a diesel engine.
The mechanical efficiency of diesel engines is generally greater than that of petrol engines due to several factors. Diesel engines operate at higher compression ratios, which leads to better thermal efficiency and more complete combustion of fuel. Additionally, diesel fuel has a higher energy density and lower volatility compared to petrol, allowing for more efficient energy conversion. Furthermore, the inherent design of diesel engines, which often features simpler components and less throttling during operation, contributes to their overall mechanical efficiency.
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.
