Knowledge Of CNG Vehicle Application

 Five key points to save

1. Don't step too hard, accelerate in sequence to start the most fuel-efficient way

Driving aggressively and pursuing a sense of speed can sometimes be contradictory. To save gas, you need to avoid stepping on the gas pedal too hard when starting. Stepping on the gas pedal too hard can increase gas consumption by 2 to 3 times compared to normal speeds. In fact, to reach a speed of 60 kilometers per hour, pressing the accelerator again and gradually accelerating, the difference in time between the two driving methods is less than 10 to 20 seconds. To save gas, don't compete for the pleasure of more than ten seconds.

2. Maintaining a distance without frequently applying the brakes saves more energy

If you don't maintain the distance between the cars, it's easy for you to need to brake on the road. When you press the brake, the automatic transmission gear will decrease, and the car will have to be pulled up from low gear again. When starting from a standstill or low gear, the engine will have to consume a higher amount of air. Next, the method of driving is very important. We all know that the distance between two points is the shortest in a straight line. If you frequently change lanes, the driving distance is also relatively long, which will consume a little more gas. However, if you frequently change lanes, in order to overtake, you must press the accelerator hard, which will naturally increase gas consumption.

3. Don't be too fast, it's too expensive and gas intensive

Running on highways, besides safety, most roads in China now have a speed limit of 120. The higher the speed, the greater the consumption of gas. The resistance of a car during driving is proportional to its speed, not directly proportional. The higher the speed, the greater the wind resistance, and the greater the driving resistance. If you often drive long distances, there is an experience that if you are within 100 and 120 kilometers, it is more fuel-efficient, but if you run really fast, it will be more gas intensive. It feels like you need power, so the engine keeps supplying gas, and high-speed driving is also detrimental to fuel consumption. If the speed of the vehicle is taken as the horizontal axis and the gas consumption is taken as the vertical axis, it is a fishhook curve. Too low a speed is also quite gas consuming, and too high a speed is also very gas consuming.

4. The deviation of the vehicle is also quite exhausting

Vehicle deviation is also one of the main reasons for gas consumption, as unbalanced four wheels can cause the engine to consume more power.

5. Sudden increase in displacement, must be checked

If the gas consumption suddenly increases, it is mostly due to a loose or poorly sealed joint leaking air. It is necessary to go to a professional repair site for inspection in a timely manner to avoid air leakage causing greater accidents.

 6 questions to understand CNG modification

1. Q: Are there many changes to CNG now?

Answer: Environmental pollution is severe, and natural gas is the best medicine for environmental protection. Now, the country is also vigorously promoting natural gas, and natural gas vehicles are more environmentally friendly, cost-effective, and safe, so there are many vehicles equipped with "oil to gas" conversion.

2. Q: Is it safe to change CNG?

Answer: Regular modifications are very safe. The main thing is to ensure the airtightness of the gas transmission channel and no leakage. Also, it is necessary to use gas cylinders that meet national safety standards. When leaving the factory, each gas cylinder undergoes fire test, water pressure test, high-altitude fall test, explosion test, gunshot test, etc. to ensure that each gas cylinder is a qualified product that meets relevant national standards when leaving the factory

3. Q: Does using compressed natural gas after switching to CNG have an impact on engine lifespan?

Answer: This doubt is unnecessary. Firstly, clean natural gas is a clean energy source that produces only carbon dioxide and water after combustion, making it more environmentally friendly than burning gasoline. Moreover, the relevant departments now have very strict requirements for the dehydration and desulfurization process of gas stations in the urban area of Chengdu, which eliminates the corrosion of engines caused by harmful chemicals produced by the combustion of natural gas containing sulfur and water. Another benefit of using CNG is that it effectively avoids the problem of engine carbon buildup caused by using gasoline. 2. The correct usage method will not have any impact on the engine: natural gas has a very low temperature, with a minimum temperature of -40 ° C and a ignition point of around 680 ° C. Before use, start the car with oil and wait for the water temperature to rise to a certain temperature before changing the air, which can avoid premature aging of the engine. On the other hand, natural gas can play a role in supporting combustion.

4. Q: What is the cost of modifying CNG?

Answer: The complete set of CNG modification components generally includes gas pressure reducing valve, fuel injection simulation device, ignition advance device, conversion switch, etc. in addition to the gas storage cylinder. The total price of these complete sets of accessories varies depending on the origin, and the volume is also divided into many types, such as 50 liters, 55 liters, 60 liters, 65 liters, 70 liters, 75 liters, 80 liters, 100 liters, etc. The price depends on the weight and space of the car.

There is also an important safety reminder: When modifying CNG devices for vehicles, it is necessary to go to a professional organization with modification qualifications recognized by the Provincial Quality Supervision Bureau. During the modification process, you must also check whether all the components used are brand new. Do not only try to use old gas cylinders that have been replaced by others at a low cost, as this will not only bring significant safety hazards, but also may encounter the embarrassment of gas stations refusing to add gas.

5. Q: After modifying the CNG, are there any requirements for driving?

Answer: There are no special requirements and there is no difference between driving and regular maintenance. Maintenance should be done as usual, and there are no special requirements

6. Q: Do I need to go to the traffic management department to complete the procedures after modifying the CNG?

Answer: Yes. Generally, the application should be submitted to the vehicle management office first and can only be modified after being registered.
