A CNG (Compressed Natural Gas) tractor truck is a type of heavy-duty truck that is powered by natural gas instead of traditional diesel fuel. Here are some key features and advantages of CNG tractor trucks:
Environmental friendliness: CNG tractor trucks produce significantly lower emissions compared to diesel-powered trucks. Natural gas is a cleaner-burning fuel, resulting in reduced greenhouse gas emissions, particulate matter, and nitrogen oxide emissions. This makes CNG tractor trucks a more environmentally friendly option.
Cost savings: Natural gas is generally cheaper than diesel fuel, resulting in potential cost savings for operators. Additionally, some regions offer tax incentives or subsidies for using natural gas as a fuel, further reducing operating costs.
