Why CNG Isn't Used in Diesel Engines: Understanding the Technical Differences

Explore the reasons why CNG is not suitable for diesel engines and the complexities involved in conversions.

32 views

CNG (Compressed Natural Gas) is not commonly used in diesel engines due to the high compression ratios required for diesel combustion, which differ significantly from those needed for CNG. Converting a diesel engine to run on CNG involves complex modifications and can affect engine performance and efficiency.

FAQs & Answers

  1. What are the main differences between CNG and diesel engines? CNG engines operate on lower compression ratios compared to diesel engines, which requires different design and functionality.
  2. Can diesel engines be converted to run on CNG? Yes, but it involves complex modifications that can impact performance and efficiency.
  3. What are the benefits of using CNG over diesel? CNG is often cheaper and cleaner than diesel, producing fewer emissions, but may not be suitable for all engine types.
  4. Is it more efficient to run a vehicle on CNG or diesel? Efficiency depends on the engine design; diesel engines typically offer greater efficiency, but CNG can provide benefits in specific applications.
