1.Energy Density: Petrol has a much higher energy density than coal. This means that it can provide more energy per unit volume. This makes it more efficient to transport and store.
2.Ease of Use: Petrol is much easier to use than coal. It is a liquid, so it can be easily pumped and injected into an engine. Coal, on the other hand, is a solid that must be crushed, transported, and burned. This makes it more difficult to handle and use.
3.Emissions: Petrol produces fewer emissions than coal when burned. This is because petrol is a hydrocarbon, while coal is a fossil fuel. When coal is burned, it releases harmful pollutants such as sulfur dioxide and nitrogen oxides into the air. Petrol, on the other hand, releases relatively fewer pollutants.
4.Engine Efficiency: Petrol engines are more efficient than coal engines. This is because petrol engines operate at higher temperatures and pressures than coal engines. This allows them to convert more of the fuel's energy into motion.
5.Availability: Petrol is more readily available than coal. It is produced in large quantities and is available at gas stations around the world. Coal, on the other hand, is a limited resource that is found in certain parts of the world.
6.Reliability: Petrol engines are more reliable than coal engines. This is because petrol engines do not require the same level of maintenance as coal engines. Coal engines are prone to problems such as clogging, fouling, and corrosion.
