How to Judge the Distance of the Rear Car Using Rearview Mirrors?

Methods to judge the distance of the rear car using rearview mirrors include: 1. The position of the rear car on the outer side of the rearview mirror indicates a closer distance, while the inner side indicates a farther distance; 2. The larger the size of the rear car in the rearview mirror, the closer the distance, and the smaller the size, the farther the distance; 3. When the internal rearview mirror can see the hood of the rear car but not the grille, the distance is approximately 3 meters, and when the grille of the rear car is visible, the distance is about 8 meters. Car rearview mirrors are important safety components, and their function is to allow the driver to indirectly see the conditions behind, beside, and below the car, thereby expanding the driver's field of vision.

What is the 0-100 km/h acceleration time for the 10th generation Accord 1.5T?

According to official data, the 10th generation Accord only has one 1.5T displacement option, with a 0-100 km/h acceleration time of 8.2 seconds for the 1.5T model. The factors affecting a vehicle's 0-100 km/h acceleration time are as follows: Torque: Torque, in simple terms, represents how much force is available. The greater the torque, the more force is available to propel the vehicle, resulting in faster acceleration. The Altima has a maximum torque of 371 Nm and a 0-100 km/h acceleration time of 6.9 seconds. The 10th generation Accord's 1.5T turbocharged engine delivers 194 horsepower and a maximum torque of 260 Nm, with a 0-100 km/h acceleration time of 8.2 seconds. Transmission efficiency: The transmission is the medium for power delivery, and inevitably involves power loss. The higher the transmission efficiency, the better the acceleration performance. Generally, the ranking of transmission efficiency is as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The Altima 2.0T uses a continuously variable transmission (CVT). Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit is Hp/T). The higher the power-to-weight ratio, the faster the acceleration. The Alt

Where is the cabin air filter located in the Mazda3?

The cabin air filter in the Mazda3 is located inside the glove compartment in front of the front passenger seat. The function of the cabin air filter is to absorb various harmful substances in the air, minimizing the risk of passengers being irritated due to allergies. The Mazda3 has the following body dimensions: length 4515mm, width 1745mm, height 1465mm, with a wheelbase of 2640mm. The Mazda3 is equipped with a 1.6L naturally aspirated engine, delivering a maximum power of 79kW at 6000rpm, paired with a 6-speed manual transmission. It features a MacPherson strut front suspension and a multi-link independent rear suspension.

What engine is used in the BYD Surui?

The engine of the BYD Surui is independently developed and produced by BYD Auto Company, belonging to a domestically manufactured engine. The engine model of the BYD Surui is BYD476ZQA, with a maximum power of 80kW, maximum horsepower of 109, and maximum torque of 145 N·m. For daily maintenance of the BYD Surui engine, the following methods can be used: Use lubricating oil of 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 requirements specified by the manufacturer. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, causing various problems for the engine. To avoid malfunctions, 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 clogged 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 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 powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, 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 normally but also extends the overall lifespan of the radiator and engine.

Do Short Springs Damage the Original Car Shock Absorbers?

Short springs will not damage the original shock absorbers. If the replaced springs lower the car body by less than 25mm and the stiffness increases within 15%, the original shock absorbers can be retained. This combination is not only economical but also maintains most of the original ride comfort while improving handling and appearance. However, if the stiffness and length of the new springs exceed these ranges, matching shock absorbers must be used to ensure the system's performance can be fully utilized. Car shock absorbers are an important part of the vehicle's suspension system. Their function is to suppress the rebound impact of the springs, absorb vibrations and deformations, and mitigate road shocks. They directly affect the vehicle's ride comfort and handling, which in turn impacts driving safety. To quickly dampen the vibrations of the frame and body and improve the smoothness and comfort of the car's ride, shock absorbers are generally installed in the vehicle's suspension system. The most widely used type in cars is the double-acting telescopic shock absorber. Shock absorbers are wear-prone components during car use, and their performance directly affects the vehicle's driving stability and the lifespan of other parts. Therefore, it is essential to keep the shock absorbers in good working condition.

Why Does a Diesel Car Fail to Start Despite Having Fuel?

Here are the reasons why a diesel car may have fuel but fail to start: 1. Engine fuel line blockage: Check if the engine fuel line is unobstructed. If you hear a hissing sound from the fuel injector, it indicates the fuel line is functioning properly. 2. Cylinder compression: Inspect the cylinder compression. If the flywheel can rotate after releasing the decompression device but the cylinder compression is problematic, the cylinder piston and piston rings need replacement. 3. Lubricating oil: Replace the lubricating oil promptly. Overly viscous lubricating oil can hinder smooth engine startup. 4. Fuel pump: Check for air presence in the fuel pump. If air is trapped inside, the diesel engine will fail to start.
