What is the tire size of the Wuling Zhiguang?

The tire size of the Wuling Zhiguang is 165/70R13, and all models feature rear-wheel drive. Below is an introduction to the Wuling Zhiguang: 1. In terms of appearance, the extended version of the new Wuling Zhiguang is basically consistent with the standard version in design, with a body length of 4100mm and a wheelbase of 2750mm. Additionally, the vehicle offers a maximum cargo space of approximately 4100 liters, and even when fully loaded with passengers, it still provides 1100 liters of cargo space. 2. In terms of configuration, the new model adds features such as headlight height adjustment and a child seat anchor on the left side of the middle row compared to the older version. 3. For power, the extended version of the new Wuling Zhiguang is equipped with a 1.2L engine featuring VVT variable valve timing and ETC electronic throttle technology, delivering a maximum power of 84 horsepower and a peak torque of 116 N·m. 4. In terms of transmission, the engine is paired with a 5-speed manual gearbox. Moreover, the official fuel consumption of the new vehicle is announced as 6.5L/100km.

What Causes the Car AC Compressor to Make Noise When Turned On?

It may be caused by excessive engagement gap of the electromagnetic clutch. Below is relevant information about automotive air conditioning: 1. Introduction to Automotive Air Conditioning: The automotive air conditioning system consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components, designed to regulate the temperature and humidity inside the vehicle, providing a comfortable environment for the driver. 2. Working Principle: When the compressor operates, it draws in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser, causing it to liquefy into a liquid. The liquid refrigerant then flows through the throttle device, where its temperature and pressure decrease, and it enters the evaporator. Inside the evaporator, the low-temperature, low-pressure liquid refrigerant absorbs heat from the cabin air passing through the evaporator, causing it to evaporate into a gas. The gas is then drawn into the compressor again for the next cycle.

The Function of Car Electronic Anti-Theft Devices

Car electronic anti-theft devices function by locking the ignition and preventing vehicle startup to achieve anti-theft purposes. Once in anti-theft mode, triggered events will activate an alarm notification. The main types of electronic anti-theft systems are as follows: 1. Key-controlled type. Uses the key to lock/unlock doors while simultaneously arming/disarming the anti-theft system. 2. Remote-controlled type. The anti-theft system can remotely control door lock/unlock operations. 3. Alarm-only type. The system only sounds an alarm when theft is detected, without vehicle immobilization capability. 4. Comprehensive anti-theft system with alarm and immobilization. When theft occurs, besides audible alarms, it can cut off the starter circuit, ignition circuit or fuel system to prevent vehicle movement. 5. Electronic tracking anti-theft system. This includes satellite positioning tracking systems and two-way radio centralized monitoring systems.

What Are the Reasons Why the Car Remote Key Cannot Unlock the Door?

Possible reasons why the car remote key cannot unlock the door are as follows: 1. The car key battery is dead, causing the door to not open. If the remote control flashes when pressed, it indicates that the issue is not with the key, and the mechanical key can be used to open the door first. 2. There is strong interference around, preventing the car remote from unlocking the door. Keyless start cars have sensors inside that can start the engine as long as the key is detected. 3. It could also be due to poor circuit contact, making the door unable to open. This is a rare occurrence, and in such cases, placing the key close to the sensor should allow the car to start. 4. The car battery is dead, so the door cannot be opened. You can find another car with a working battery, connect both batteries with jumper cables, and let the car charge for a few minutes before trying again.

Why does the EA888 engine oil pressure switch function fail?

Reasons for the failure of the EA888 engine oil pressure switch function: It may be due to poor contact switch operation or grounding of the wiring harness. Symptoms of the fault: After the engine starts and the oil pressure reaches the specified value, the indicator light remains on. Solution: Promptly visit a repair shop for servicing to avoid affecting driving safety. The following is relevant information: 1. The engine oil pressure switch is used to detect whether there is oil pressure in the engine. It consists of a diaphragm, spring, and contacts. The oil pressure indicator light is installed in the combination instrument panel, and the pressure switch is installed on the engine's lubrication circuit. 2. Inside the pressure switch, there is a diaphragm that moves under oil pressure and contacts that operate under oil pressure. When the oil pressure is below the specified value, the diaphragm does not have the force to push the spring, the contacts close, and the indicator light turns on. When the oil pressure is above the specified value, the diaphragm pushes the spring, the contacts separate, and the indicator light turns off, indicating to the driver that the oil pressure has reached the specified value. Under normal conditions, the contact operating pressure ranges between 30~50 kPa.

Which is better, combined injection or direct injection?

The differences between combined injection and direct injection are as follows: 1. Different engine systems. The most critical system of a direct injection engine is the high-pressure fuel injection system, which mainly consists of four parts: the engine control module (ECM), high-pressure fuel rail, high-pressure fuel pump, and fuel injector. A combined injection engine has both direct injection and manifold injection systems. 2. Different fuel injection methods. Direct injection is a technology that directly injects fuel into the cylinder to mix with the intake air, while combined injection combines the advantages of manifold injection and direct injection. Under low-load conditions, the manifold injector sprays fuel during the cylinder's intake stroke, allowing the mixture to enter the cylinder, and then the cylinder injector sprays fuel during the compression stroke to achieve stratified combustion. Under high-load conditions, only direct injection is performed during the compression stroke, thereby improving the engine's efficiency and avoiding the emission issues caused by excessive oxygen under low-load conditions in direct injection engines. 3. Different costs. Since a combined injection engine integrates both direct injection and manifold injection systems, with two sets of fuel pumps and fuel supply pipelines, its cost is significantly higher than that of a direct injection engine.
