What Causes Fuel Injector Leakage?

Why does the car steering wheel suddenly become heavy?

Reasons for a heavy steering wheel: 1. Dirty power steering fluid. This situation is similar to how dirty engine oil affects engine power and performance. Dirty power steering fluid can cause the steering wheel to become increasingly heavy, and a lack of power steering fluid can also make the steering wheel feel heavier. 2. If it is an electric power steering system, check whether the fuse is blown, and whether there is an open circuit or a short to ground in the wiring. Repeatedly turning the steering wheel while stationary or at low speeds places a heavy load on the power steering system, which can easily cause the steering gear to overheat and enter a protective mode, resulting in heavy steering. It will return to normal after cooling down, which is a normal phenomenon.

How to Check the Production Date of Car Glass When Buying a Car?

Methods to check the production date of car glass: 1. The production date of car glass is usually marked in the lower right corner of the window or below the trademark. It is presented in the form of a single number. The markings on the glass can provide information about the brand, structure, specifications, and production date of the glass. 2. In the production date of the glass, the number represents the year. The black dots on the left side of the number represent the production month. Black dots on the left indicate the first half of the year, while those on the right indicate the second half. 3. If the black dots are on the left, subtract the number of dots from 7 to determine the production month. If the black dots are on the right, subtract the number of dots from 13.

How to Distinguish Between China IV and China V Standards?

Methods to distinguish between China IV and China V standards are as follows: 1. For vehicles that have already obtained the environmental protection inspection compliance label, the emission standard can be checked on the original or duplicate copy of the label. Alternatively, you can log in to the Motor Vehicle Environmental Protection Website and enter the vehicle model number and engine model in the New Vehicle Compliance Query System. 2. According to the national plan, the China VI emission standard is scheduled to be implemented on July 1, 2020, just three years after the full implementation of the China V standard. In key regions such as the Beijing-Tianjin-Hebei area and its surrounding regions, the Yangtze River Delta, the Fenwei Plain, the Pearl River Delta, and the Chengdu-Chongqing region, the China VI standard will be implemented ahead of schedule. 3. The China VI standard raises the threshold by nearly 50% compared to the current China V standard and is slightly stricter than the current international strictest emission limit—the Euro VI standard. Once officially implemented, the China VI standard will become the world's most stringent motor vehicle emission standard.

What Are the Hazards of Oil Emulsification to the Engine?

The Hazards of Oil Emulsification: Oil emulsification can lead to a reduction in various performance aspects of the oil, not only affecting the vehicle's power performance and fuel economy but also increasing the engine's wear. Over time, this can easily lead to bearing seizure and even complete engine failure. Causes of Oil Emulsification: 1. Cylinder Liner Damage: This is likely due to cracks in the cylinder liner, allowing coolant to seep through the cylinder wall directly into the oil pan. Alternatively, it could be due to aging of the cylinder liner sealing ring, in which case the seal should be checked. 2. Engine Water Plug Leakage: If the engine water plug is severely aged, it will definitely leak. In this case, coolant will mix directly into the oil pan, making regular inspection of the water plug crucial. 3. Radiator Damage: Additionally, damage to the oil cooler pipes can also cause water to enter the oil. 4. Cylinder Head Gasket Damage: Due to prolonged high-pressure conditions inside the cylinder, the cylinder liner may become damaged, causing the oil and coolant passages to interconnect, leading to oil emulsification.
