You will find three types of NGVs:
· Dedicated: These vehicles are designed to operate only on natural gas
· Bi-fuel: These types of vehicles have two individual fueling systems that allow them to run on either gas or gasoline.
· Dual-fuel: These kinds of vehicles are traditionally restricted to heavy-duty applications, have energy systems that run on propane, and use diesel gas for ignition assistance.
Light-duty vehicles typically operate within dedicated or bi-fuel settings, while heavy-duty vehicles run in dedicated or dual-fuel modes. On the vehicle, petroleum is stored in tanks because CNG. LNG, a more costly option, is used in some heavy-duty vehicles. The form of natural gas utilized is typically chosen based on the variety an application needs. Because it is the liquid, the energy density associated with LNG is greater than CNG, so more fuel could be stored onboard the vehicle. Can make LNG well-suited for Course 7 and 8 vehicles requiring a greater range.
Generally, dedicated NGVs demonstrate improved productivity and have lower emissions compared to bi-fuel vehicles. Additionally , devoted NGVs only have one gasoline tank, so they aren't since heavy as bi-fuel NGVs and offer more cargo capability. The driving range of NGVs is generally less than that of similar conventional vehicles because of the reduced energy density of oil. Extra storage tanks may increase range, but the excess weight may displace payload potential.
