Natural gas vehicle - Wikipedia
A natural gas vehicle (NGV) utilizes compressed natural gas (CNG) or liquefied natural gas (LNG) as an alternative fuel source.
How Do Natural Gas Vehicles Work? - Alternative Fuels Data Center
Compressed natural gas (CNG) vehicles operate much like gasoline-powered vehicles with spark-ignited internal combustion engines. The engine functions the same way as a gasoline engine. Natural gas is stored in a fuel tank, or cylinder, typically at the back of the vehicle.
Natural Gas Vehicle - an overview | ScienceDirect Topics
Natural gas vehicle (NGV). NGV vehicles use combustion engines and pressurized natural gas fuel instead of gasoline. The main constituent of natural gas is methane with an octane value of 130; NGV engine compression ratios can reach as high as 15:1. Higher compression ratios increase engine efficiency.
The pros and cons of natural gas engines - Greg's Petroleum
Natural gas engines operate very similarly to diesel and gasoline engines using a spark-ignited internal combustion engine. Fuel is stored in a tank, then injected into the engine where it is ignited by a spark plug system which causes the engine to run. There are also three different types of NGV engines:
NGVs and hydrogen vehicles include engine R&D, onboard fuel storage and delivery, vehicle integration, fueling infra-structure, codes and standards, vehicle evaluation, and consumer awareness and perceptions.

A natural gas vehicle or NGV is an alternative fuel vehicle that uses (compressed or liquefied) natural gas instead of other fossil fuels.
Natural Gas Vehicles - Nicor
Natural Gas Vehicles (NGVs) are powered by compressed natural gas (CNG) or liquefied natural gas (LNG). Both are cleaner, safer and less expensive than traditional fuels. New developments in engine and vehicle technology, more stringent air quality regulations, and government incentives make this choice increasingly attractive.

HOW A NATURAL GAS VEHICLE (NGV) WORKS - KERETA DOT …
2008年7月12日 · HOW A NATURAL GAS VEHICLE (NGV) WORKS 1. Natural gas is compressed and enters the vehicle through the natural gas fill valve (receptacle). 2. It flows into high-pressure cylinders located in or under the vehicle. 3. In a bi-fuel NGV, a fuel selector on the dash permits selection of natural gas or gasoline. A dedicated NGV operates solely on ...
Why NGV? – The Transport Project
The newest natural gas engines with Near-Zero – or Zero Emissions Equivalent – technology exceed stringent new federal NOx emissions standards. Natural gas engines are certified to the CARB Model Year 2024 standard without using credits.
