Why CNG Is Better Than Diesel?

For a long time, diesel has been the most cost-effective fuel for fleets. Until the reality about particulate matter and NOx emissions became known, it was likewise thought to be the most environmentally friendly liquid to burn. OEMs have been cleaning up their act and investing extensively to ensure that their diesels meet the tough Euro 6d-temp emission standard, but the market will not have full faith in “black fuel” again tomorrow.

But what if diesel isn’t an option? The answer could very well be compressed natural gas (CNG), especially for long-distance drivers who, if their car has a g-tron, TGI, or G-Tec badge, will not be frowned upon entering a low-emission zone in Hamburg or any other major city. Here are ten reasons to go to the gas station.

  • Low fuel price. CNG is 30 to 50 percent less expensive per kg than diesel. The fuel usage is nearly the same for both: between 4 and 6 units per 100 kilometers, resulting in a 30 to 50% reduction in the fuel expense.
  • Hybrids are better for long distances. Because of the added weight, once a hybrid’s battery is drained – which happens after only 50 kilometers unless you have a new BMW X5 45e or Mercedes GLE 350de – the combustion engine has to work extra hard, resulting in less-than-ideal fuel economy. CNG, on the other hand, has a range of 300 to 400 kilometers on natural gas and 70 to 150 kilometers on gasoline.
  • NOx and PM emissions are extremely low. Natural gas produces far fewer nitrogen oxides (NOx) and particulate matter (PM) when combusted than diesel or even gasoline. In addition, the combustion process is quieter. As a result, CNG is a superior ‘urban’ fuel to diesel.
  • Lower CO2 emissions, both at the source and at the point of use. Natural gas-powered vehicles release about 30% less CO2 than gasoline-powered vehicles and are roughly equivalent to diesel. When comparing well-to-wheel performance, CNG easily outperforms conventional fossil fuels.
  • CNG is abundant. Natural gas reserves on the planet are vast, ensuring a steady supply for decades to come. Natural gas prices are also independent of oil prices. They are less prone to change and have stayed quite constant in recent years.
  • CNG has the potential to be a long-term solution. Methane, the major component of CNG, can be produced from biological waste and sludge. Audi manufactures it by splitting water into oxygen and hydrogen, which are then blended with CO2 to form a carbon-neutral product.
  • Hybrids are more expensive. A CNG car is approximately €1,500 more expensive than the petrol model from which it is developed. And the model lineup is growing: Audi, Fiat, Iveco, Mercedes-Benz, Opel, SEAT, Skoda, and Volkswagen all offer at least one CNG variant.
  • Infrastructure development. As more petrol stations offer CNG, a fundamental barrier to CNG automobiles’ popularity is beginning to erode. In 2025, Germany will have 2,000 natural gas stations, up from 860 currently. Belgium, despite its small size, already has 100 stations.
  • Cars that run on compressed natural gas may park underneath. CNG automobiles, unlike LPG vehicles, are not prohibited from parking in underground garages. LPG is heavier than air and can spread over the car park’s floor, causing a concern. CNG, on the other hand, is a flammable gas.
  • CNG is a completely safe fuel. The gas tanks are composed of extremely durable materials such as carbon fiber reinforced plastic and are subject to stringent safety measures (CRFP). They can withstand pressures of up to 750 bar, high heat, and collisions. There are also safety valves on the tanks.

Why CNG is a better option than diesel?

In comparison to gasoline or diesel, CNG is a clean-burning fuel that leaves little or no residue when used. As a result, the risk of damage to the vehicle’s engine’s pipes and tubes is considerably minimized. There is also less particulate debris in the engine oil to pollute it.

Is CNG cleaner than diesel?

Compressed natural gas (CNG) as a transportation fuel is a well-established technology that is widely employed in many regions of the world. Despite being a fossil fuel, compressed natural gas is currently the cleanest burning fuel in terms of NOx and soot (PM) emissions.

CNG may be used to power passenger vehicles as well as city buses. CNG passenger vehicles release 5-10% less CO2 than gasoline-powered counterparts. In general, there is little gain in terms of CO2 emission reduction when compared to diesel-powered vehicles. CNG-powered vehicles, on the other hand, emit far less NOx and soot than diesel-powered vehicles. For city buses, which are frequently diesel-powered, the benefits of CNG lie in improving local air quality rather than lowering CO2 emissions. The advent of compressed natural gas (CNG) in the transportation industry is a good impetus for biogas. Biogas has the potential to reduce CO2 emissions by over 80%.

Why CNG is not good for car?

You might be concerned about your fuel costs as gasoline prices rise. If you have a petrol vehicle, the obvious solution is to install a CNG conversion kit aftermarket. But did you realize that there are a number of drawbacks to installing CNG? In today’s topic, we’ll go through the key drawbacks of using CNG in your vehicle.

Decreased Boot Space

The first and most significant disadvantage for CNG car owners is the lack of cargo capacity. There are occasions when you are left with almost no boot room, particularly in hatchbacks and sedans under 4 meters. If you wish to install CNG, we recommend purchasing a sedan if you frequently take lengthy trips. This is one of the most significant downsides of installing CNG in your vehicle.

Decreased Power Output

Another significant disadvantage of CNG is its lower power output. If you’re used to driving a petrol automobile, you’ll notice a big difference in power output. You will notice a big loss in power the day you switch to CNG, especially on long summer journeys when the air conditioning is at its maximum.

Frequent Service Intervals

If you’re moving to CNG, you’ll need to pay closer attention to your car’s servicing schedule. The reason is straightforward. When you run your car on CNG, the spark plugs and engine oil wear out faster than they should. If your automobile runs on CNG, you’ll need to visit the service center more frequently and keep an eye on how the engine is doing. If you’re driving on CNG, you’ll have to pay greater attention to your vehicle.

Decreased Resale Value

You can avoid this issue if you identify a suitable buyer. If you have an aftermarket CNG installed in your vehicle and plan to sell it to a dealer, expect a price drop. This can also be advantageous. If you’re shopping for a secondhand car, a CNG vehicle is less expensive than a gasoline vehicle!

Long Wait For Refuelling

Another downside of using CNG in your automobile is that you will have to wait longer than you would if you were using gasoline. Given that it is now 2021, many new CNG stations have opened, but the number of CNG vehicles has also increased. Overall, you will undoubtedly have to wait longer than at a gas station. Is the time spent waiting worth the money saved on gas? It’s entirely up to you.


Another significant disadvantage of CNG is that your cylinder must be hydro checked every three years. This is a mandatory test that you must do in order to guarantee that your CNG cylinder is safe to use. Do you have a day off only for this test in today’s fast-paced world? You make the call!

Lack of Knowledge

The term “company fitted CNG” refers to a situation in which the manufacturer takes care of everything. If you opt for a retro-fitted CNG kit, you must ensure that the installation is done correctly, as well as the engine oil, HP and LP filters, and so on. The knowledge transfer will not be done by every dealer or service technician. When it comes to your car, be cautious about who you trust.

Last but not least, if your vehicle is BS6 compliant, retro-fitted CNG cannot be registered on your vehicle’s RC at this time. Either buy a car with a factory-installed CNG system or keep driving it on gasoline.

Why CNG is a good fuel?

CNG is good for the environment because it emits less pollutants. CNG is one of the most environmentally friendly fuels available. Carbon monoxide emissions are reduced by 90 to 97 percent when CNG is used. In fact, changing one truck from diesel to natural gas reduces pollution by the same amount as removing 325 automobiles from the road. Natural gas, rather than diesel or gasoline, helps to minimize small soot particles that can aggravate asthma and other respiratory problems.

Is CNG good option?

CNG cars are gaining favor over other fuel sources due to a plethora of advantages. CNG is a terrific fuel from a safety standpoint, as well as for the environment and your car. Always protect your cash with a car insurance coverage, regardless of the fuel type. In this post, we’ll look at the benefits of owning a CNG-equipped vehicle versus one that runs on conventional fuel.

Which fuel type car is best?

While petrol automobiles have a lot of power at first, diesel cars have more power in higher ratios. Diesel cars, on the other hand, have a higher fuel economy than gasoline ones. This means that if you only need to travel small distances within the city, a petrol car is far more practical.

Is CNG harmful for health?

According to a study undertaken by the Council of Scientific and Industrial Research, compressed natural gas (CNG) buses are detrimental to humans because they release “nanocarbon” particles that might cause cancer (CSIR). These particles are travelling through the atmosphere and are inhaled directly through your nose.

Is CNG cheaper than diesel?

CNG engines have a lifespan of 10-12 years, compared to 6-8 years for diesel engines.

CNG is 30 to 50 percent less expensive per litre than diesel. CNG is also more cost-effective due to its improved fuel usage.

Lower CO2 emissions: CNG-powered vehicles emit 30% less CO2 than diesel or gasoline-powered vehicles.

CNG is plentiful: In comparison to dwindling fuels like gasoline and diesel, the Earth’s natural gas supplies are plentiful.

CNG is environmentally friendly: Methane, the primary component of CNG, can be produced from biological waste and sludge, making it more environmentally friendly.

CNG cylinders are built of tough materials like carbon fiber reinforced plastic and are subject to stringent safety measures (CRFP).
