What is the normal tire pressure for Wuling Zhiguang?

The tire pressure for Wuling Zhiguang is between 2.4 and 2.5 bar. This vehicle is a microvan-level car launched by SAIC-GM-Wuling in May 2020. In terms of body dimensions, the Wuling Zhiguang has a length of 3797mm, a width of 1510mm, a height of 1835mm, and a wheelbase of 2500mm. In terms of power, it is equipped with an LSI naturally aspirated engine, paired with a 5-speed manual transmission (MT), delivering a maximum horsepower of 76PS, a maximum power of 56KW, and a maximum torque of 108N.M. Measuring tire pressure: The tire pressure of a cold tire is different from that of a hot tire, so attention should be paid during measurement. The difference between the two is approximately 0.3 bar. A cold tire is one that has been parked for at least three hours and has not been driven more than 2 kilometers. If you can only measure the tire pressure when the tire is hot, subtract approximately 0.2 bar from the measured value to obtain the tire's cooling inflation pressure. On roads with significant bumps, it is advisable to reduce the tire pressure by 0.1 to 0.2 bar from the standard tire pressure.

Why doesn't the steering wheel return to center?

The reasons why the steering wheel cannot return to center are as follows: 1. Uneven tire inflation on both sides. Inconsistent tire pressure is one of the main causes of weak return force. To diagnose this issue, a tire pressure gauge must be used. The side with lower tire pressure will have a wider contact patch with the ground, naturally encountering greater road resistance, causing the car to pull toward the side with lower pressure. 2. Uneven tire inflation on both sides. If there is a significant difference in tire wear between the left and right wheels, it can pull the steering wheel to one side. This can usually be addressed by rotating the tires. After driving 10,000 kilometers, the tires should be rotated.

What is the body length of the Refine M4?

The length, width, and height dimensions of the Refine M4 are 5200mm/1890mm/1980mm, which are official data. The length of the Refine M4 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and respectively touching the outermost protruding parts at the front and rear of the vehicle. The width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and respectively touching the outermost rigid fixed protruding parts on both sides of the vehicle. The height refers to the distance between the highest point of the vehicle and the vehicle's supporting plane. The turbocharged engine of the Refine M4 has a maximum power of 163kW and a maximum torque of 385 Nm. This engine has a maximum horsepower of 222 and a maximum torque speed range of 1500 to 3500 rpm. It is equipped with direct injection technology and uses an aluminum alloy cylinder head. This engine is paired with a 6-speed automatic transmission. The state has relevant regulations regarding vehicle dimensions. According to the national standard 'GB1589-89,' the total width of a vehicle does not include the rearview mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. In other words, the significance of vehicle width data in the national standard is to ensure enough space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, the state stipulates that the total width of a vehicle must not exceed 2.5m to meet the usage requirements of public roads.

Is the Weight Limit for Five-Axle Vehicles 46 Tons or 43 Tons?

Five-axle vehicles have a nationally unified total weight limit of 43 tons. According to the 2004 national standard GB1589-2004 'Limits of Dimensions, Axle Load and Masses for Road Vehicles' and the 2000 Ministry of Transport Order No. 2 'Regulations on the Administration of Over-Limit Transport Vehicles Operating on Highways', the vehicle's total axle load limit and the total weight limit of the vehicle and cargo are compared, and the smaller of the two is taken as the judgment standard. A five-axle vehicle refers to a vehicle with one axle per row, totaling five rows of wheels, meaning it has five sets of tires. An axle refers to the cylindrical component that passes through the wheel hub to bear the weight of the vehicle body. The axle mainly consists of the axle neck, wheel seat, dustproof plate seat, axle body, and center hole. The number of axles in a vehicle is mainly applied to cargo trucks, military vehicles, special vehicles, or a small number of large buses. The vehicle axle (also called the axle) is connected to the frame (or load-bearing body) through the suspension, with wheels installed at both ends. Function: The suspension, not the axle, transmits forces and moments between the frame and the axle (wheels). The role of the axle is to bear the vehicle's load and maintain normal driving on the road. Ordinary family cars generally use a single axle. Road transport vehicles with a total mass of less than 19 tons and axle loads not restricted by roads or bridges, as well as vehicles not operating on highways, such as mining dump trucks, use a two-axle solution with a simple structure and low manufacturing cost.

What is the 0-100 km/h acceleration time for the Binrui 1.4T?

According to official data, the 2021 Binrui 1.4T achieves 0-100 km/h acceleration in 8.9 seconds. Factors affecting a vehicle's 0-100 km/h acceleration time include: Torque: Torque, in simple terms, represents the strength of the force. The greater the torque, the stronger the force pushing the vehicle, resulting in faster acceleration. For example, the 2021 Santana has a maximum torque of 145 Nm and a 0-100 km/h acceleration time of 12.6 seconds, while the 2021 Binrui 1.4T model has a maximum torque of 235 Nm and accelerates from 0-100 km/h in 8.9 seconds. Transmission efficiency: The transmission acts as a medium for power delivery and inevitably involves power loss. Higher transmission efficiency leads to better acceleration performance. Generally, transmission efficiency ranks as follows: manual transmission > dry dual-clutch transmission > wet dual-clutch transmission > AT transmission > CVT transmission. The 2021 Binrui 1.4T is equipped with a manual transmission (MT). Power-to-weight ratio: The relationship between horsepower and vehicle weight is called the power-to-weight ratio (unit: Hp/T). A higher power-to-weight ratio results in faster acceleration. For instance, the 2021 Santana has a power-to-weight ratio of 100 Hp/T and a 0-100 km/h acceleration time of 12.6 seconds, while the 2021 Binrui 1.4T model has a power-to-weight ratio of 111 Hp/T and accelerates from 0-100 km/h in 8.9 seconds.

What Causes Low Idle Speed in Vehicles?

Idle speed in a car does not refer to a specific speed, but rather to an operational condition. When the engine is running without load, it is referred to as idling. The reasons for low idle speed in vehicles include: 1. Malfunction of the idle speed control valve. 2. Poor atomization or clogging of the fuel injectors. 3. Changes in oil viscosity. The hazards of excessively low idle speed are as follows: 1. Low idle speed makes it easier for the engine to stall when starting, and frequent use of the starter is detrimental to both the engine and the starter. 2. Low idle speed can lead to stalling during gear shifts while driving, which is very dangerous. This is particularly risky when following other vehicles closely, as it increases the likelihood of rear-end collisions. 3. Engine shaking at idle causes significant wear and tear on the engine.
