Question

Write a report outlining the advantages and disadvantages of using Compressed Natural Gas (CNG) as an automobile fuel compared to diesel, discussing why CNG might be preferred as a fuel option for vehicles.

Answer 1

CNG offers advantages such as cleaner emissions, better engine performance, and domestic availability, but it has drawbacks including lower energy density and limited refueling infrastructure.

Step-by-step explanation:

Advantages of using Compressed Natural Gas (CNG) as an automobile fuel:

• CNG is a cleaner-burning fuel compared to diesel, emitting lower levels of pollutants like carbon dioxide, nitrogen oxides, and particulate matter.
• CNG has a higher octane rating than diesel, resulting in better engine performance and lower maintenance costs.
• CNG is more abundant and domestically available, reducing dependence on imported oil.

Disadvantages of using CNG as an automobile fuel:

• CNG has a lower energy density than diesel, resulting in a shorter driving range and the need for larger fuel tanks.
• The infrastructure for CNG refueling stations is limited, making it less convenient for drivers to find refueling options.
• The initial cost of converting vehicles to run on CNG can be expensive.

Despite these disadvantages, CNG might be preferred as a fuel option for vehicles due to its environmental benefits, potential cost savings, and reduced reliance on fossil fuels.
