Because of their larger piston travel, hence they have higher load carrying capacity making them useful for trucks.
Why petrol is not used in heavy vehicle and diesel not in lighter vehicle?
Petrol is highly combustible than Diesel. Petrol gives quick energy compared to Diesel. It is not suitable for heavy vehicles because by burning of petrol it gives lot of energy in a short time. At this circumstances, the vehicles has to move quick but due to heavy load it cannot as a result the cylinder may burst.
Which fuel is used in heavy vehicles?
Diesel acts as fuel for heavy motor vehicles.
Why are there no petrol trucks?
This is simply an essential requirement in any heavy automobile. Since petrol engines generate lower RPM, they result in quick fuel burning. Needless to say, petrol engines for heavy vehicles are simply not a practical option. On the other hand, diesel engines for trucks provide better fuel economy.
Why is diesel cheaper than petrol?
Diesel fuel is heavier and less volatile than gasoline, which makes it simpler to refine from crude oil. As a result, diesel tends to be cheaper than gasoline in most countries around the world. … If the demand for diesel fuel is higher, the price spread will widen.
Is petrol heavier or lighter than water?
Gasoline floats on water which means that water has a higher density than gasoline. … The weight of one gallon of commonly used fuel, like that of gasoline, is six pounds. To put this into context with water, a gallon of water weighs about 8.4 pounds.
How fuel is used in vehicles?
A gasoline car typically uses a spark-ignited internal combustion engine, rather than the compression-ignited systems used in diesel vehicles. In a spark-ignited system, the fuel is injected into the combustion chamber and combined with air. The air/fuel mixture is ignited by a spark from the spark plug.
Why is gas used in cars?
Gasoline provides many advantages in running a car or other vehicle. Quick Starting – Because it is highly-combustible, vehicles powered by gasoline usually start up more quickly than other vehicles. Fast Acceleration – Gasoline accelerates much better than other fuels.
Why does UK have no petrol?

Are we running out of petrol?
Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years, natural gas up to 53 years, and coal up to 114 years.
Why do diesel cars disappear?
The usage of expensive filters in BS-VI-compliant diesel engines and the huge money-input by the companies will result into Diesel cars getting a lot pricier, which will, eventually, lead to a steep drop in their demand. In order to curb the tailpipe emissions, India will adopt BS-VI emission norms in April 2020.
Is gas better than diesel?
Diesel fuel simply packs more energy in every gallon than gas fuel, which makes it more economical overall. … Diesel cars also have more torque, which results in better fuel economy along with more impressive acceleration.
What is the difference between petrol and diesel?
How do petrol and diesel engines differ? … The difference between petrol and diesel is found in the way that the combustion occurs. Whilst a petrol engine combines fuel with air before being ignited by spark plugs, in a diesel engine the air is compressed beforehand and then the fuel is injected.
