What are the reasons why an automatic transmission car does not move when shifted to R gear?

There are two main reasons why an automatic transmission car does not move when shifted to R gear: mechanical faults and operational issues. Mechanical faults: If components such as the transmission, oil pump, torque converter, control wiring, solenoid valves, or switches malfunction, the reverse gear may fail. The solution is to first check if the transmission has insufficient oil, whether the main oil pressure and gear oil pressure are normal, and then verify if the gear switch signal is functioning correctly. Additionally, inspect the wiring from the transmission computer to the shift solenoid valves and ensure the gear solenoid valves are working properly. If all these components are in order, it indicates an issue with the internal control system of the transmission, requiring disassembly to examine the internal actuators. Operational issues: If the electronic parking brake is not released or the gear shift is not properly engaged, the reverse gear may also fail to function. The solution is to check if the electronic parking brake is released and release it promptly if necessary. If the issue is not related to the parking brake, it is advisable to visit a repair shop to inspect whether the gear synchronizer in the transmission is stuck or if there are other faults.

What is the normal width of a sedan?

The width of a sedan is generally between 1600mm and 1800mm. The length of sedans ranges from 3800mm to 4300mm, and the height ranges from 1400mm to 1600mm. Vehicles such as jeeps, micro cars, light passenger cars, light trucks, and small special-purpose vehicles are basically classified as small vehicles. The key role of sedan width is passenger space and flexibility. For passenger cars, if three seats arranged side by side are required to have a spacious seating feel (primarily sufficient shoulder width), the vehicle width should reach 1800mm. In recent years, due to increased safety requirements, the thickness of door panels has been increased, leading to a general increase in vehicle width. Japanese cars have quite strict restrictions on width, with most being under 1800mm, while European cars tend to increase vehicle width. However, if a car body is too wide, it will reduce the convenience of driving and parking in urban areas. Therefore, for cars, a width of 2000mm is a recognized upper limit. Cars approaching or exceeding 2000mm in width are generally very difficult to drive.

What are the reasons for the insufficient cooling of the Bisu T5 air conditioner?

The reasons for the insufficient cooling of the Bisu T5 air conditioner are as follows: 1. The car is not started: The compressor of the car air conditioner is driven by the car engine. If the car is not started, the air conditioning system can only blow air but cannot cool or heat. This situation is relatively simple to solve. You just need to start the vehicle and then turn on the air conditioner. 2. The air conditioner compressor is damaged: If the car air conditioner compressor is damaged, the air conditioner will definitely not cool. There are many reasons for the damage of the air conditioner compressor, and it is necessary to go to the repair shop for a detailed inspection by professionals. 3. The air filter is clogged: If the car's air filter is not cleaned or replaced for a long time, it will affect the air supply capacity of the air conditioner, so the air conditioner will not cool. In this case, the air filter should be cleaned or replaced in time. 4. The engine belt slips: The car air conditioner compressor is driven by the engine. If the engine belt slips, it cannot deliver power to the compressor, affecting its normal operation. In this case, the engine belt should be repaired or replaced in time.

In which year was the Volkswagen R36 discontinued?

This model was discontinued in 2010. Below is more information about the Volkswagen R36: 1. The Passat R36 was equipped with a 3.6-liter naturally aspirated VR6 engine, which produced 299 horsepower and a maximum torque of 350 Nm. This engine could deliver maximum power at 6,600 rpm and maximum torque between 2,400 and 5,300 rpm. 2. This engine featured direct fuel injection technology and used an aluminum alloy cylinder head and block. It was paired with a 6-speed dual-clutch transmission, specifically a wet dual-clutch transmission, which offers better reliability, stability, and smoother gear shifts. 3. The Passat R36 used a MacPherson independent suspension at the front and a multi-link independent suspension at the rear. The car also came with a full-time all-wheel-drive system.

What do the gear letters in a car represent?

Cars are divided into automatic and manual transmissions, with automatic transmission cars having gears marked with letters. The gear positions on a car are as follows: 1. P: Park. 2. R: Reverse. 3. N: Neutral. 4. D: Drive. 5. S: Sport mode. 6. L: Low gear. Here is more detailed information about the gears: 1. P stands for Park gear: When a car needs to be parked for a long time, shifting to P gear prevents the car from rolling because the car is in a mechanical lock state. P gear must only be used when the car is completely stopped; otherwise, it may damage the locking mechanism and the transmission. 2. R gear represents Reverse gear: Used when the car is reversing. Before reversing, the car must be completely stopped, and the safety button on the shift lever must be pressed to move the lever to R gear. 3. N gear stands for Neutral gear: This gear is not used for long periods. The working principle of Neutral gear is the same in both automatic and manual transmission cars. It is typically used when waiting at traffic lights. When the car is in Neutral, the connection between the transmission and the engine's power system is disconnected. 4. D gear represents Drive gear: Drive gear is the most frequently used gear. When in Drive, the transmission automatically shifts gears based on the car's speed, enabling automatic gear changes. The saying 'D gear for all situations' refers to this gear. 5. S gear stands for Sport mode: Sport mode is mainly used when going uphill or overtaking. The car can switch to Sport mode while driving. After switching to Sport mode, the engine's RPM increases rapidly, and the car's speed also improves. 6. L gear represents Low gear: This gear is equivalent to first gear in a manual transmission car. It is primarily used during long downhill descents, allowing the car to maintain the lowest gear and reducing the need for constant braking.

What does 16v engine mean?

16v engine refers to an engine with 16 valves. For engines of the same displacement, more valves generally mean better performance. To improve intake and exhaust efficiency, multi-valve technology is now widely used. It is common to have 4 valves per cylinder, so a 4-cylinder engine would have a total of 16 valves, hence the designation 16V. Below is some extended information about valves: 1. The function of valves is to specifically input air into the engine and expel the exhaust gases after combustion. Structurally, valves are divided into intake valves and exhaust valves. The intake valve's role is to draw air into the engine to mix with fuel for combustion, while the exhaust valve's role is to expel the burned gases and dissipate heat. 2. Valves are responsible for inputting fuel into the engine and expelling exhaust gases. Traditional engines have only one intake valve and one exhaust valve per cylinder. This design is relatively simple, cost-effective, easy to maintain, and performs well at low speeds. However, the drawback is that it is difficult to increase power, especially at high speeds where the air charging efficiency is low and performance is weaker.
