Compressed Natural Gas (CNG) Certification Practice Exam 2025 - Free CNG Certification Practice Questions and Study Guide

Question: 1 / 400

How does CNG configure within a dual-fuel system?

It operates only with gasoline

It operates alongside diesel, allowing for flexibility in fuel choice

In a dual-fuel system, CNG can be configured to operate alongside diesel, which provides operators with the flexibility to choose between the two fuel types based on factors like availability, cost, and emissions. This configuration allows for a more adaptable approach to fuel management, as vehicles can switch between CNG and diesel as needed, optimizing performance and potentially reducing fuel costs.

By using CNG in a dual-fuel system, operators can take advantage of the cleaner-burning properties of natural gas while still having the reliability of diesel fuel when required, especially in regions where diesel infrastructure is more developed. This versatility can lead to significant operational benefits, especially in fleet management, where fuel choice may impact economic and environmental strategies.
