Those who are looking for an alternative to petrol or diesel and who are not attracted to electric power may well be interested in CNG. A modern fuel that must be distinguished from the LPG.
If natural gas for vehicles – CNG – is still only at its beginning, it deserves to be known for its multiple advantages and qualities. A true alternative solution for sustainable mobility, it is used by cars as well as buses, coaches, and heavy goods vehicles. Why is it interesting to use CNG on a daily basis?
CNG: an environmental and economical solution
Made up of more than 94% methane, Natural Gas for Vehicles is simply natural gas, like the one we use daily at home for heating or cooking. Distributed by network, it is the primary energy available in large quantities, which does not require any transformation.
And if CNG is so exciting, it is mainly because it provides a real alternative to petroleum products and represents the future of sustainable mobility. of sustainable
- Clean fuel that emits no black smoke or bad odors and almost no fine particles
- Up to 70% reduction in Nox emissions compared to diesel
- No indirect pollution as for other fuels: its transport and distribution are ensured by a network of pipes
- 50% reduction in noise pollution
- An economical solution: 20 to 30% savings compared to a conventional fuel
Its use thus reduces CO 2 emissions by up to 23% compared to petrol.
As air pollution in urban areas is mainly due to vehicle traffic, many cities are now implementing measures to improve air quality and respond to this health and climate emergency.
Thus, the Low Emission Zones system, associated with the car fleet trend, reserves cities’ access to the least polluting vehicles.
The technical advantages of CNG
More peaceful, more efficient, and more flexible vehicle … CNG also offers many technical advantages.
Light vehicles first benefit from greater autonomy thanks to bi-fuel, petrol taking over in the event of an empty CNG tank.
More technically, the CNG is very slow combustion, which makes the vehicle engine much less noisy. No more vibrations inside the passenger compartment, natural gas, offer comfort and drive flexibility superior to conventional fuels.
The life of the car is also multiplied by 3 and the longevity of the engine multiplied by 2. Indeed, the natural gaseous state of the CNG saves the engine and avoids dirt and any problem linked to liquid fuels, such as mixing with engine oil.
Some disadvantages of CNG vehicle
This is precisely one of CNG’s biggest disadvantages to date: the number of CNG service stations, although booming, but it is still limited.
Besides the problem of recharging the gas, the fact remains that the CNG tank takes up more space than a conventional fuel tank and remains expensive in terms of installation. Whether buying an equipped vehicle or transforming a standard vehicle, CNG costs around twice as much as LNG. Consequently, the use of this 0067as still struggles to convince a large number of individuals, while captive fleets of vehicles (taxis, buses) are more seduced.
