Question

Name the product of petroleum that is used to drive heavy vehicles.

Answer 1

Hint: The different products of petroleum have different applications. The light vehicles are run by petrol. The petrol burns at a faster rate compared to that of the diesel. Thus, petrol is efficient for light vehicles, whereas diesel is efficient for the heavy vehicles.

Complete step by step answer:
The highest torque is required by the heavy vehicles to even run at the lowest speed. As the petrol runs at a faster rate compared to that of the diesel, thus, petrol cannot provide the required torque to the heavy vehicles as per requirement. The diesel fulfils this requirement. The efficiency of the engine of the vehicles is expected to be greatest when run by the diesel, than petrol. The power and durability of the heavy automobiles are increased/maintained by the diesel.
The disadvantages of the diesel are: This fuel is one of the most expensive when compared to its manufacturing process and its maintenance. The requirements for the emission should be taken care of while importing the diesel.
Therefore, one of the products of petroleum, diesel is used to drive heavy vehicles.

Note: An important list involving the products of petroleum and their applications/usage should be known to solve this type of theoretical problems. Even the noise and the vibrations in the automobiles are reduced by usage of the diesel as fuel. A petroleum-based fuel named gasoline used in most of the lightweight automobiles. The advantages of using this fuel are: provides fast acceleration, quick start application, noiseless operation and it is a powerful energy source.
