How to maintain your CNG car?

CNG cars have successfully entered the Indian way of life and have gained popularity over the past decade because of their cheaper operating costs and environmentally friendly nature.

What is a CNG car?

Suitable for automobiles that use natural gas as fuel, compressed natural gas is a good vehicle fuel, and many vehicles can burn natural gas or gasoline. Existing gasoline-powered vehicles can be converted to use CNG or LNG, and can be dedicated (only use natural gas) or dual fuel (use gasoline or natural gas).

The diesel engines of heavy-duty trucks and buses can also be modified and dedicated by adding new headers containing a positive ignition system, or they can run on a mixture of diesel and natural gas, the primary fuel being natural gas and a small amount. Diesel is used as an ignition source. More and more vehicles in the world are manufactured to use compressed natural gas.

In terms of maintenance, CNG cars need more care than gasoline cars. However, the CNG car maintenance tips list here will be of help to you.

Set the car to automatic refueling mode. When the automatic refueling mode is activated, the engine first starts in gasoline mode. When the temperature rises to a certain level, it will automatically switch to CNG mode. The automatic fuel mode is very beneficial to the general condition of the engine because the fuel helps to lubricate the engine in the best way.

Always park the car in the shade. In CNG cars, the cylinders are composed of gases that evaporate faster than gasoline and diesel. Therefore it is always recommended to park compressed natural gas vehicles in the shade. It can also help you avoid entering the heating compartment of the car because of the scorching sun rays. This is probably the simplest maintenance technique you should follow often.

Spark plug inspection. The spark plugs of CNG cars differ greatly from the spark plugs of gasoline cars because the gap between the spark source and the metal tip of CNG spark plugs is shorter. Make sure that your car’s spark plug is suitable for compressed natural gas vehicles. It is recommended to replace the spark plug every 10,000 kilometers.

Air filter. When cleaning or replacing the air filter, a dirty air filter basically hinders the fuel efficiency of a CNG car. Check your car’s air filter regularly. It is recommended to clean and replace the air filter every 5000 kilometers in time.

Keep the throttle body clean. The throttle body controls the car’s throttle response and is connected to the air filter. When checking the air filter, check the throttle body and clean it if it is dirty. The replacement filter cartridge filter box is usually called a CNG filter. The reducing filter cartridge and the low-pressure filter must be changed to every 40,000 km and 20,000 km respectively. The correct replacement of the ink cartridge can extend the life of the engine.

CNG cylinder inspection: First of all, don’t drive the car for too long with low CNG content, because it will reduce the cylinder pressure and increase the risk of valve explosion. Also, maintain a regular flow of gasoline in the engine and fuel tank.

Also, don’t forget to replace the valves regularly, as they will wear out after a certain age. Check for CNG leaks If you feel CNG leaks, don’t panic. Instead, turn off the engine and close the cylinder outlet to prevent gas from flowing out of the car. Call any reliable service center immediately for further processing.

Frequently Asked Questions

What is the CNG Venturi Kit?

The design of the CNG Venturi kit is like the design of the carburetor, and the working method is also similar. During the intake stroke, the Venturi kit adds a specific amount of gas to the fuel and injects it into the cylinder. You must manually switch to CNG mode and gasoline mode. The Venturi kit can be installed on any type of car. Besides the advantages of low cost and simple structure, the Venturi kit has more disadvantages, it requires frequent maintenance, less picking, and occasional clogging.

What is a continuous GNC kit?

In the sequential CNG kit, the gas injection is electronically controlled by a separate ECU (Electronic Control Unit). The sequential injection kit can be installed in a car with an electronic fuel injection system. CNG sequence kits are useful as they are helpful in providing better mileage, relatively infrequent maintenance.

Are CNG cars suitable for long-distance highway driving?

Choose. It will save a lot of fuel and maintenance costs. Is CNG fuel economy better? CNG is very light and clean. When used as fuel, it can reduce engine pressure and make it produce better fuel efficiency. However, the cost of CNG is much lower than other fuels, making it the most economical operating cost for driving CNG vehicles.

Common Misconceptions about CNG cars.

Many people have been worried about fuel price increases in recent years. We expect gasoline prices to fall sometime in the future, but we are not sure yet. Therefore, there is nothing wrong with switching to GNC. We know some factors may worry you, but are they really true? Well, let’s find out the myth that we talk about CNG cars in today’s topic!

Poor acceleration: A majority of petrol and diesel car owners impose on CNG-based cars, is poor acceleration. While the argument can not be refuted largely, however, unless you are someone who gets his kicks from the power of acceleration, CNG vehicles are not much different in terms of realistic performance while driving. Speaking of after-sales kits, if you have the right accessories, you don’t have to worry about acceleration. Don’t you believe us? Have an endurance race between the same gasoline and CNG vehicles and see for yourself.

Not suitable for off-road: But assured, if you have the right CNG car and equipment, you can definitely have fun on any terrain. For example, if you have a Honda CRV with a locally manufactured or assembled kit, you want it to behave like a real SUV, and it certainly won’t. CNG cars are not suitable for all terrains. This is definitely one of the myths of CNG cars. You can easily take your CNG car wherever you want, if you find the terrain is very steep, you can switch to gasoline!

Reduce engine life: Another common misconception in CNG car myths is that these machines have a short lifespan. Now, if you have a WagonR, for example, you can consider producing nearly 200,000 kilometers, right? If properly maintained, an engine powered by CNG will provide you with the same performance. Regular service and timely replacement of parts can help you get the best results!

Shorter suspension life: if you are equipped with the right things, you no longer have to worry about the suspension. Obviously, your car is always cylinder-loaded, so the rear suspension will wear out quickly. The factory-installed CNG cars have suspension pads.

CNG cars are not safe: Did you know that the ignition temperature of CNG is 700 degrees Celsius, while gasoline is only 455 degrees Celsius? Yes, if the temperature inside the system rises anyway, gasoline vehicles will catch fire earlier than CNG vehicles! All you need to deal with is leakage. To do this, simply perform a hydraulic test on your cylinder within the specified time limit.

The cruising range of CNG cars is shorter: Who said that the cruising range of CNG cars is shorter than that of gasoline cars? We agree that gas cylinders are smaller than gas tanks, but when you are traveling on the road, as long as you run out of CNG, you can easily switch from CNG to gasoline. This is just your perception! CNG cars always have more range than gasoline cars because it has 2 fuel tanks!

Compressed Natural Gas is difficult to get: People think that another big misunderstanding in compressed natural gas vehicles is that fuel is difficult to obtain. Well, it may not be easily available in mountainous areas or small towns, but in large cities where people use CNG for daily commuting, it is easy to get, and the government is snowballing CNG filling stations in more areas of the country.

CNG cars UnreliableL Look at Maruti’s CNG car sales figures. Do they look unreliable? CNG cars are very reliable and you can rely on them every time you travel. Just make sure that your vehicle is properly and promptly serviced. You never have to worry about reliability anymore!

Low resale value: When it comes to resale value, dealers always use one trick or another to give you a price lower than you deserve. Claiming that your car is a CNG car and paying less is the most common trick today. Instead, look for real customers who really need CNG cars for daily commuting. Anyone who has a proper understanding of the reputation of CNG cars will pay a fair price for buying one!

Lack of qualified CNG mechanics. Another most common misconception about CNG cars is that you cannot find a qualified mechanic nearby to repair or fix your car. Attended. Now that companies like GoMechanic are here, you don’t have to worry about anything else.

India’s car sales share in the fiscal year 2020–2021 (by fuel type):

In the fiscal year 2021, most of the cars sold in India are gasoline models, with a market share of 76%, despite the increase in gasoline costs that year. This is an enormous increase from 67% in the previous year. Diesel vehicle sales dropped from 29% to 17%. This was a significant reduction of 54% in the 2013 fiscal year.

While Petrol-powered vehicles are certainly the rage, CNG will catch up in due time. Considering its many advantages that outweigh its limitations, those who drive often, should definitely consider CNG vehicles over the other variants.

Would you choose to drive a CNG fueled car too?
