Use of CNG instead of diesel reduces air pollution because

Options

A. it is cheaper
B. it burns efficiently
C. catalytic converters work efficiently
D. it cannot be adulterated

Answer

To answer the question "Use of CNG instead of diesel reduces air pollution because," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding CNG**: CNG stands for Compressed Natural Gas. It is primarily composed of methane, which is a cleaner-burning fuel compared to diesel.

2. **Comparison of Carbon Content**: The carbon content in CNG is significantly lower than that in diesel. This means that when CNG is burned, it produces fewer carbon emissions.

3. **Efficiency of Combustion**: CNG burns more efficiently than diesel. This means that it produces more energy per unit of fuel consumed and generates fewer pollutants during combustion.

4. **Emission of Harmful Substances**: The combustion of CNG results in lower emissions of harmful substances such as nitrogen oxides (NOx), particulate matter, and unburned hydrocarbons, which are prevalent in diesel emissions.

5. **Conclusion**: Therefore, the use of CNG instead of diesel reduces air pollution primarily because it burns efficiently and produces fewer harmful emissions due to its lower carbon content.

### Final Answer:
The use of CNG instead of diesel reduces air pollution because it burns efficiently and has lower carbon content, resulting in less harmful emissions.
