Why is there a lack of acceleration after replacing spark plugs?

The reason for a lack of acceleration after replacing spark plugs is that the spark plug model does not match the vehicle. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the firing order, then secure the cover. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it's recommended to follow the user manual. You can refer to the following standards for maintenance replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.

What is the fuel tank capacity of the Kia K2 in liters?

The fuel tank capacity of the Kia K2 is 43 liters, as officially announced. Owners who have purchased the Kia K2 can also check this information on the vehicle's configuration sheet. The Kia K2 requires 92-octane fuel, with a fuel consumption of 5.0 to 6.5L per 100 kilometers. A full tank can cover a distance of 662 to 860 kilometers. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level, with additional space left between the safe fill level and the tank opening. This extra space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity.

Can You Drive with Low Rear Tire Pressure?

Tire pressure that is too low makes driving unsafe. Continuing to drive with low tire pressure will cause excessive internal wear, and even a brand-new tire can quickly become worn out and unusable. It is best to replace it with the spare tire before driving and then go to a repair shop to fix the punctured tire. Therefore, when tire pressure is low, switch to the spare tire before driving. Alternatively, keep a portable car air pump on hand, which can be used to inflate the tire when pressure is low. Once properly inflated, you can drive normally. A portable car air pump typically costs around 200 yuan and draws power from the cigarette lighter or battery, making it a very practical tool. Checking Tires: To avoid insufficient tire pressure while driving, pay close attention to your tires during regular use. If tire pressure drops unexpectedly, inspect the tire for punctures or embedded nails. If a puncture is found, repair it promptly or replace the tire entirely. Additionally, if the tire sidewall is damaged, it is generally not recommended to repair it; instead, replace it with a new tire. Regular Cleaning: If you frequently drive on roads with many small stones, they often get lodged in the tire treads. It is best to develop a habit of regularly cleaning your tires in daily life. If the vehicle has been parked for an extended period without use, check the tire pressure before driving again to ensure it is adequate. Avoid developing poor driving habits, such as parking on roadside stones, as this can damage the tire sidewalls.

What are the common faults in engine cooling systems?

Common faults in engine cooling systems are as follows: Low exhaust temperature in the refrigeration system: Low exhaust pressure, although the phenomenon appears on the high-pressure side, the cause mostly originates from the low-pressure side. Refrigeration system experiencing liquid return: For small refrigeration systems using capillary tubes, excessive refrigerant charging can cause liquid return. High suction temperature in the refrigeration system: Insufficient refrigerant charge in the system or too small an expansion valve opening can lead to inadequate refrigerant circulation, resulting in less refrigerant entering the evaporator, high superheat, and consequently high suction temperature. Refrigeration system with liquid start-up: The phenomenon of violent foaming of lubricating oil in the compressor is called liquid start-up. Refrigeration system experiencing oil return: Oil shortage can cause severe lubrication deficiency. The root cause of oil shortage is not the amount or speed of oil running in the compressor, but poor oil return in the system. Evaporation temperature in the refrigeration system: Temperature greatly affects refrigeration efficiency. For every 1-degree decrease, 4% more power is required to produce the same cooling capacity. Therefore, appropriately increasing the evaporation temperature, when conditions permit, is beneficial for improving the efficiency of air conditioner refrigeration. Excessive exhaust temperature in the refrigeration system: The main reasons for excessively high exhaust temperature include high return gas temperature, large motor heating, high compression ratio, high condensing pressure, adiabatic index of the refrigerant, and improper refrigerant selection. Adding fluorine to the refrigeration system: When the amount of fluorine is small or its regulating pressure is low (or partially blocked), the valve cover (bellows) of the expansion valve, and even the liquid inlet, may frost; when the amount of fluorine is very small or almost none, there is no visible reaction on the expansion valve, only a slight hissing sound of airflow can be heard. Low suction temperature in the refrigeration system: The expansion valve opening is too large.

What engine is used in the Geely Boyue?

Geely Boyue's engine is produced by Geely Automobile itself, utilizing Volvo's technology, making it a domestically manufactured engine. The engine model of the Geely Boyue is JLE-4G18TDC, a 1.8T version with a maximum power of 135kw/5500rpm and a maximum torque of 285Nm/1500-4000rpm. The 2.0L version has a maximum power of 104kw/6000rpm and a maximum torque of 178Nm/4000-4500rpm. For daily maintenance of the Geely Boyue's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly according to usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

After a certain mileage, its performance deteriorates, leading to various engine problems. To avoid faults, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from part wear to form sludge. Small amounts remain suspended in the oil, while large amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
