The function of a rear axle limited-slip differential is to limit the speed difference between the two tires. When the vehicle turns, the left and right tires can automatically adjust their rotation speeds to accommodate the different lengths of the turning paths, allowing the vehicle to turn smoothly. The rear axle limited-slip differential indeed makes the car turn more smoothly, but due to its inherent structural limitations, it also has drawbacks. When a car is driving on a curve, there is a certain difference in the rotation speeds of the inner and outer wheels. The outer wheel travels a longer distance and thus rotates faster than the inner wheel. The differential is used to create this speed difference between the wheels, allowing for reasonable torque distribution between the left and right wheels during a turn to achieve an appropriate turning effect. At this point, a differential is needed to regulate the speeds, and most vehicles are equipped with a differential.

How to Read a Car Tire Pressure Gauge?

Tire pressure gauges are generally divided into three types: analog (dial) tire pressure gauges, digital tire pressure gauges, and alarm-type tire pressure gauges. The latter two can display tire pressure through numerical values or alarms, and their principles are relatively simple. However, analog tire pressure gauges need to be connected to the tire valve stem to check the car's tire pressure, and then the tire pressure can be read by observing the pointer on the gauge head. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data for each tire is displayed. When the tire pressure is too low or there is a leak, the system will automatically issue an alarm. Indirect Tire Pressure Monitoring: When the air pressure in a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to the other wheels. By comparing the differences in rotation speeds between the tires, the purpose of monitoring tire pressure is achieved. Indirect tire alarm systems actually rely on calculating the rolling radius of the tires to monitor air pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, and a 4-wheel indirect system is also equipped. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low air pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as a direct system does.

Which gear should the Tayron be in when waiting at a red light?

The Tayron should be in D gear with the brake pedal pressed when the red light duration is less than 30 seconds. If it exceeds 30 seconds, shift to N gear and engage the handbrake. Car gears include: P gear, R gear, N gear, D gear. Related introduction to car gears: P gear is the parking gear: When the gear lever is in the P gear position, the transmission is in neutral internally, but the output shaft is mechanically locked. At this time, the car will remain stationary even without pressing the brake, and it is generally used for long-term parking. When engaging P gear, the car must be completely stationary. Do not engage P gear when the car is not fully stopped, and always engage the handbrake. When parking on a slope, engage the handbrake first before shifting to P gear. R gear is the reverse gear: When the gear lever is in the R gear position, the rotation direction of the transmission's output shaft is opposite to that of the engine, allowing the car to move backward. When engaging R gear, the car must be completely stationary. Do not engage R gear when the car is not fully stopped. N gear is the neutral gear: When the gear lever is in the N gear position, the gears inside the transmission are in a freewheeling state, and the clutch is not engaged, resulting in minimal load on the transmission. N gear is generally used for short-term parking, such as waiting at a red light, and the transmission should also be in N gear when the car is being towed. D gear is the driving gear: When the gear lever is in the D gear position, the gears inside the transmission automatically shift between the lowest and highest gears based on factors such as vehicle speed and throttle opening, according to the preset shifting pattern. In most cases, D gear can be used for driving.

What engine does the SAIC Maxus G20 use?

The Maxus G20 is equipped with a 2.0T turbocharged engine from SAIC's Blue Core series, which is produced by SAIC Motor Corporation. The SAIC Maxus G20 has a maximum horsepower of 224ps, a maximum power output of 165kw, and a maximum torque of 350nm. For the daily maintenance of the SAIC Maxus G20'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 deteriorate over time during use. After a certain mileage, its performance will degrade, leading to various engine problems. 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 becomes 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 particles from component wear to form sludge. When the amount is small, it remains suspended in the oil; when large, it 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 deposits not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What are the differences between a differential lock and a differential?

The differences between a differential lock and a differential are as follows: 1. Different functions: The differential lock locks the machine 100%, while the differential allows a certain differential response. The main function of the differential is to create a speed difference between the two wheels to ensure stability during cornering. The role of the differential lock is to lock the differential, eliminating the speed difference between the two wheels and preventing the vehicle from slipping. 2. Different uses: The differential lock is mostly used for climbing and off-roading, while the differential is mostly used for track racing (such as touring car racing). However, some off-road vehicles use differentials for Dakar rallies, and racing cars use them for extreme drifting.

What is the best position to install ETC?

For small cars, the ETC device is generally installed on the upper middle part of the front windshield, while for large vehicles such as trucks and buses, it is installed on the lower middle part. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, which may affect the signal transmission of the microwave communication link, the ETC should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply for ETC, the vehicle owner needs to provide original and photocopied versions of their valid ID card and vehicle license. If the application is not made by the owner, the agent must also bring their valid ID card. The photocopy of the vehicle license should include the page with the most recent annual inspection stamp. Additionally, a bank card under the owner's name for deducting highway tolls is required, and the owner must be between 18 and 60 years old. Here are some precautions for installing ETC: Do not block the driver's view; it is best to install it behind the rearview mirror: Many car models have windshields with a large backward tilt angle, which can reduce the driver's field of vision. If this is not considered during ETC installation, it may increase blind spots for the driver. Installing it behind the rearview mirror on the right side can help avoid blocking the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper rod connected to a switch. After the electronic tag is installed, the windshield will press the anti-tamper rod in. If the tag is removed arbitrarily, the rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. In such cases, you will need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of more than 10 meters from the vehicle ahead to prevent automatic toll payment for the wrong vehicle. The ETC lane recognizes vehicles at a speed of 20 kilometers per hour; driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. When using a debit card linked to ETC, insufficient balance may also cause toll deduction failure.
