Video transcript

CNG in diesel engines works through a dual-fuel system where compressed natural gas (CNG) is introduced into the intake manifold. The engine starts on diesel fuel, and once running, CNG is injected while the diesel acts as a pilot to ignite the gas. This process results in reduced emissions and improved fuel efficiency. Retrofitting a diesel engine for CNG might require specialized conversion kits and tuning, providing an eco-friendly and cost-effective solution for heavy vehicles.

Questions and answers
