Efficiency of Diesel Engines vs Petrol Engines
Diesel engines are known for their higher efficiency compared to petrol engines in practical applications. The efficiency of an engine is determined by the amount of energy from the fuel that is converted into useful work.
Diesel Cycle vs Otto Cycle
In the case of diesel engines, they operate on the diesel cycle, which is a type of thermodynamic cycle that is more efficient than the Otto cycle typically used in petrol engines. The key difference between the two cycles is the compression ratio, with the diesel cycle having a higher compression ratio.
Explanation of Assertion and Reason
The assertion that diesel engines are more efficient than petrol engines is true, and the reason provided is also true. The higher efficiency of diesel engines can be attributed to the higher compression ratio of the diesel cycle, which leads to better thermal efficiency.
Correct Answer Justification
Option C is the correct answer because while the assertion is true, the reason provided is false. The efficiency difference between diesel and petrol engines is not solely based on the compression ratio but also on other factors such as combustion process, fuel properties, and engine design.
