What is the main reason to adjust the fuel intake system for CNG use?

The primary reason for adjusting the fuel intake system for CNG (Compressed Natural Gas) use is to accommodate gaseous fuel. CNG has different physical properties compared to liquid fuels that are typically used, such as gasoline or diesel. The fuel intake system must be designed to handle gas rather than liquid, requiring modifications to components such as injectors, mixing systems, and fuel lines to ensure proper gas flow and optimal combustion.

This adjustment is crucial for ensuring that the engine receives the correct air-fuel mixture needed for efficient combustion. Since CNG is a gas, the system must efficiently convert this gaseous fuel into a form that can be effectively mixed with air and ignited in the combustion chamber. By ensuring that the fuel intake system is tailored for gaseous fuel, the engine can operate safely and efficiently on CNG.
