Why Do CNG Vehicles Consume Too Much Gas?

When using natural gas, excessive fuel consumption is related to improper installation and adjustment of the compressed natural gas pressure reducer. The advantages of natural gas vehicles include the following: 1. Higher economic benefits: For the same equivalent heat value, countries around the world generally control the price of 1 cubic meter of natural gas to be half that of 1 liter of gasoline or diesel. If the thermal efficiency of various engines is relatively similar, the fuel cost of natural gas vehicles is approximately half that of gasoline or diesel vehicles. This compensates for the shortage of liquid fuel supply caused by the increasing number of vehicles and significantly reduces operating costs. 2. Better social benefits: Compared to petroleum fuels, gaseous fuels have smaller energy losses during preparation and emit fewer harmful pollutants into the atmosphere. From the perspective of fuel sources, they are more environmentally friendly. 3. Relatively safer: The gas cylinders or tanks of CNG, LNG, and LPG vehicles are sturdy and reliable. Natural gas itself is lighter than air (except for LPG), so any slight leakage quickly disperses into the atmosphere. All components of the gaseous fuel system, especially the sealing parts, undergo rigorous inspection. Therefore, natural gas is relatively safer as an automotive fuel.

What is the situation when there is abnormal noise in the rear axle of the car?

The situations when there is abnormal noise in the rear axle of the car are: 1. Insufficient gear oil or decreased viscosity: If caused by such reasons, it can be improved by changing the oil, adding sufficient oil quantity, or switching from multi-grade oil to single-grade oil, or using oil with a higher viscosity grade; 2. Abnormal noise caused by improper bearing clearance: If the bearing clearance is too small, there will be a relatively uniform continuous sound, while if the clearance is too large, there will be chaotic abnormal noise, which increases with the speed of the car; 3. Abnormal noise caused by gear tooth surface damage: If the tooth surface of the bevel gear is severely damaged, the wear exceeds the limit, or the clearance is too large, there will be abnormal noise during driving, along with metal friction sounds. The noise increases with the speed of the car, and when coasting in neutral, the noise significantly weakens or disappears, indicating severe tooth surface damage or broken teeth.

What Does Tire Cupping Mean?

Tire cupping refers to the abnormal and severe wear on the inner or outer edges of one or more tires. The primary cause of tire cupping is incorrect wheel alignment data, which requires a four-wheel alignment adjustment. Otherwise, it will affect the tire's lifespan and compromise safe driving. The reasons for tire cupping include: 1. Inaccurate four-wheel alignment, leading to cupping when wheels on the same side operate or front and rear wheels are misaligned, causing abnormal friction and accelerated wear on specific tire areas due to vehicle self-correction; 2. Incorrect toe adjustment can also cause cupping—front wheels are slightly tilted inward at a toe-in angle, which is optimal for high-speed stability. All vehicles have their own toe angle, and improper adjustment can result in cupping; 3. Steering gear failure may also lead to cupping or pulling; 4. Uneven or deformed chassis can cause abnormal tire wear; 5. Mixing tires of different specifications or having significantly uneven tire pressure can result in cupping.
