What brand is the MQ200 manual transmission?

The manual transmission in the POLO is the MQ200 manual transmission. Below is a relevant introduction to the manual-automatic transmission: 1. Overview: A manual-automatic transmission is a transmission device that combines the functions of manual and automatic shifting. This technology was developed to improve the fuel efficiency and controllability of automatic transmissions, allowing the shift timing, which is usually determined by the computer, to be returned to the hands of the driver, thereby enhancing driving operability and enriching the driver's experience. 2. Working Principle: Structurally, a manual-automatic transmission mainly consists of a conventional gearbox (same as a manual transmission), an electronically controlled clutch, an automatic shift control mechanism, and an electronic control unit. The function of the electronically controlled clutch is to automatically engage, disengage, or 'slip' the clutch as needed. During operation, the transmission ECU controls a stepper motor to push the clutch fork, engaging or disengaging the clutch. The automatic shift control mechanism automatically engages the corresponding gear as needed, generally equipped with two stepper motors, both controlled by the transmission ECU. The gear lever setup is similar to that of a conventional automatic transmission, with no clutch pedal.

Should Car Windows Be Tinted?

Car windows do not need to be tinted. Here is some relevant knowledge about car window tinting: Functions of car window tinting: Heat insulation and sun protection. Tinting can effectively block a large amount of heat generated by infrared rays. UV protection. Medium and long waves of ultraviolet rays can penetrate thick glass, but applying tint film can block most UV rays, preventing skin damage and reducing the aging of car interiors. Safety and explosion-proof. The base layer of the film is made of polyester, which has excellent tear resistance and penetration prevention. Combined with the adhesive layer, the strength of the glass after tinting can prevent injuries to passengers caused by accidental glass breakage. Disadvantages of car window tinting: Tinting the side and rear windows with dark film can significantly impair the driver's vision and field of view, especially during nighttime and in low-visibility conditions such as rain or fog. This becomes even more severe when the driver needs to check the road conditions from the sides or rear while turning or reversing. The driver's line of sight is severely obstructed, directly affecting their judgment of the vehicle's surroundings during turns or reversing, which can easily lead to traffic accidents and endanger the lives of the driver and passengers.

Why should you maintain a safe distance in waterlogged sections?

Due to the slippery road surface, the braking distance of a car is longer, and the friction coefficient between the brake pads and brake discs is also smaller, affecting braking performance and increasing the risk of accidents. Therefore, it is necessary to increase the following distance. Additional information on safe driving through water: 1. Slow down: When driving through waterlogged sections, always reduce your speed. The vehicle should be in a low gear, maintaining a speed of 5 to 10 km/h or even lower. This prevents water splashes from entering the engine compartment or air intake, which could cause the engine to stall, and also considers the safety and movement of surrounding vehicles and pedestrians. 2. Pass in sequence and keep a safe distance: When driving through waterlogged sections, maintain a sufficient distance from the vehicle in front and pass through the waterlogged area one by one. The main purpose is to avoid water waves caused by the vehicle ahead flooding the engine compartment or air intake, leading to stalling. 3. Maintain a steady speed: When driving through waterlogged sections, pass through at a steady speed, avoiding sudden acceleration. The speed should be kept around 5 to 10 km/h, ideally reducing it to below 5 km/h. Additionally, keep the throttle steady to pass through the waterlogged section smoothly.

Does the Engine Start-Stop Technology Harm the Car?

Engine start-stop technology generally does not harm the car. The start-stop function only stops the engine from working, but the oil system does not stop. This means that although the engine is not rotating, the oil will still flow inside the engine, ensuring better lubrication and protection for the engine when the car starts again. Here is a detailed introduction to the engine automatic start-stop technology: 1. Definition: Engine automatic start-stop technology is a system that can automatically control the engine shutdown and ignition, known as STOP&START in English, abbreviated as STT. Vehicles equipped with engine automatic start-stop technology will automatically shut down the engine when temporarily stopping during driving. When it is necessary to continue moving forward, the system will automatically restart the engine. Generally, the automatic start-stop function is enabled by default in vehicles, and the owner can choose to turn it off if not needed. 2. Advantages: The advantage of engine start-stop technology is fuel savings. Whether waiting at a red light or in traffic jams, the engine automatic start-stop technology can automatically shut off the engine when the car stops, thereby saving fuel. However, the cost of using the car may increase. Additionally, due to the frequent repeated start-stop of the engine, there is a higher demand for oil quality, leading to further increases in maintenance costs.

Can Flood-Damaged Vehicles Be Registered?

Flood-damaged vehicles can be registered, but they must pass inspections and have complete documentation before being eligible for registration. Flood-damaged vehicles refer to those that have been submerged in water. The extent of water immersion determines the severity of vehicle damage, generally categorized into three levels: 1) water level reaching the tires, 2) water level reaching the hood, and 3) water level reaching the roof—listed from least to most severe. Typically, the first category is not a major concern, while the second and third are more serious. Purchasing flood-damaged vehicles requires caution. If the goal is to reduce costs, opting for such vehicles may be acceptable, but they offer no guarantees regarding vehicle lifespan or driving safety. Only Category 1 flood-damaged vehicles are advisable for purchase. Categories 2 and 3 are not recommended, even at lower prices, due to compromised safety. When buying a car, it's crucial to pay close attention and thoroughly check local policies to avoid purchasing unregisterable vehicles. Used Cars: Many used cars fail to meet emission standards. Annual inspections are mandatory, and if tailpipe emissions are non-compliant, the vehicle may face scrapping, rendering it unregisterable and unfit for road use. Non-Compliant with China 6 Standards: With the implementation of China 6 policies, some China 3 vehicles are now subject to mandatory scrapping.

What are the hazards of shifting directly from R to P gear?

Hazards include the P gear directly locking the gears. When the gears are rotating at high speed, they are suddenly caught by the hook of the P gear, causing the wheels to lock instantly or the gears to be damaged directly. Below is an introduction to car gears: 1. P gear: P is used for parking. It uses a mechanical device to lock the rotating parts of the car, preventing the car from moving. When the engine is running, as long as the gear lever is in the driving position, an automatic transmission car can move easily. When parking, the gear lever must be shifted into the P position, thereby locking the output shaft through the internal parking brake device of the transmission and tightening the hand brake to prevent the car from moving. When the car needs to stay in a fixed position for a long time or before leaving the vehicle after parking, the hand brake should be pulled and the lever pushed into the "P" position. 2. R reverse gear: R gear should be used when reversing. Automatic transmission cars do not have the semi-clutch function like manual transmission cars, so special attention should be paid to the control of the accelerator pedal when reversing. Usually, the safety button on the lever must be pressed to move the lever to the "R" gear. It is important to note that when the vehicle has not completely stopped, it is absolutely not allowed to forcibly shift to the "R" gear, otherwise the transmission will be severely damaged.
