What are the symptoms of a faulty steering gear?

Symptoms of a faulty car steering gear are as follows: 1. Difficulty in steering wheel return: Vehicle steering wheels have an automatic return function. Cars equipped with hydraulic power steering gears may experience a weakened automatic return function due to hydraulic damping. However, if the return speed is too slow, it indicates a malfunction in the return function. 2. Steering wobble or deviation: If the car noticeably drifts to one side after ruling out tire pressure issues, it is likely caused by a loose or broken mechanical component in the steering gear. 3. Uneven steering effort: When the driver feels that one side of the steering is lighter while the other side is heavier, this symptom is usually caused by a leak in the seal responsible for sealing one side of the high-pressure chamber. Another possible cause is improper adjustment of the directional limit valve. 4. Steering gear oil leakage: Oil leakage from the steering gear is a more obvious symptom. If abnormal steering is noticed, check for oil leaks or seepage on the steering gear, which may be related to aging seals or oil pipes in the steering gear.

What is the width of an 8-lane road?

Standard lane width: 3.75 meters; Emergency stopping lane: 2.5 meters; Central divider: 1 meter; For an 8-lane road including emergency stopping lanes: 3.75X8+2.5X2+1=36 meters; Including other ancillary facilities (guardrails, etc.), it can be calculated as 40 meters. U-turn rules at traffic lights: 1. No U-turn allowed when there is no left-turn lane before the traffic light; 2. No U-turn allowed on the crosswalk at the traffic light, must pass the crosswalk before making a U-turn; 3. If there are clear signs prohibiting U-turns or left turns at the traffic light intersection, no U-turn is allowed at any time; 4. No U-turn allowed when the road centerline at the traffic light intersection is a double solid yellow line. If it's a double yellow line with one solid and one dashed, vehicles on the dashed side can make a U-turn, while vehicles on the solid side cannot; 5. If there are yellow grid lines at the traffic light intersection, U-turns are allowed, but vehicles must not stop on the yellow grid lines; 6. If there is a U-turn sign or a dedicated U-turn signal light, follow the green light instruction to make a U-turn; 7. If there is no U-turn light but there is a left-turn light, wait for the green light in the left-turn lane before making a U-turn.

Is a Major Overhaul Necessary for Insufficient Cylinder Pressure?

Whether a major overhaul is necessary for insufficient cylinder pressure can be divided into the following two scenarios: 1. Fault in the valve train: This leads to insufficient cylinder pressure, and in this case, a major overhaul is not required. 2. Piston ring wear: When piston rings are worn, valve seals are not tight, cylinder gasket seals are not tight, or the cylinder itself is worn, a major overhaul is necessary. Below are the reasons for insufficient cylinder pressure: 1. Severe piston ring wear leading to reduced sealing effectiveness: There are three piston rings—two compression rings and one oil ring. The compression rings prevent the fuel-air mixture from entering the crankcase, while the oil ring primarily serves a lubrication function, reducing wear on the cylinder walls and piston rings. 2. Abnormal wear such as scoring or unevenness on the cylinder walls: Carbon deposits or other foreign particles enter the cylinder and scrape the cylinder walls during piston movement, causing scoring. 3. Poor sealing of the valve seats or spark plug seats: Excessive torque during spark plug installation can damage the threads. Carbon buildup can cause poor sealing of the valve seats, as carbon deposits adhere to the valves, preventing them from closing properly against the valve seats, resulting in insufficient cylinder pressure and gas leakage.

What are the advantages and disadvantages of dry and wet dual-clutch transmissions?

Dry dual-clutch and wet dual-clutch transmissions share similarities but also have differences. Neither is inherently superior to the other, as each has its own strengths and weaknesses. Below is a comparison of their advantages and disadvantages: 1. Dry-type has inferior heat dissipation compared to wet-type: Due to poorer heat dissipation, dry dual-clutch transmissions face higher risks of clutch plate overheating or even burning in congested urban areas. In this aspect, wet dual-clutch transmissions demonstrate higher technological maturity. 2. Dry-type offers higher power transmission efficiency: Wet dual-clutch transmissions rely on hydraulic fluid. The wet-type clutch plates are immersed in transmission fluid, which provides better heat dissipation. From the perspective of technological maturity and reliability, wet dual-clutch transmissions are more stable in operation since the clutch plates work in hydraulic oil that aids in cooling. However, wet dual-clutch transmissions have more complex structures, higher manufacturing costs, and slightly lower power transmission efficiency compared to dry-type. Additional information: Dual-clutch transmissions are categorized into dry and wet types. Both types operate on fundamentally similar principles, featuring two clutches that alternate in operation.

What is the fuel tank capacity of the 2017 Corolla in liters?

The Corolla has a total of 12 models currently on sale. Among them, the 1.8L displacement models have a fuel tank capacity of 43 liters, while the remaining models have a fuel tank capacity of 50 liters. This data is officially released, and Corolla owners can also check it on their vehicle's configuration sheet. The Corolla uses 92-octane fuel. The 1.8L displacement models have a fuel consumption of 4 to 4.1L per 100 kilometers, allowing a full tank to cover a distance of 1049 to 1075km. The other models consume 5.1 to 5.6L per 100 kilometers, enabling a full tank to travel between 8929 to 9804km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safe fill level. There is additional space from the safe fill level to the tank opening, designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual fuel volume may exceed the calibrated tank capacity.

Where is the fuel tank cap switch of Borgward BX5 located?

Borgward BX5's fuel tank cap switch is located on the right side of the vehicle body, and the fuel tank cap can be opened by pressing it. Common methods to open the fuel tank cap: 1. Mechanical key method: This type of fuel tank cap switch is relatively rare, usually found on some hardcore off-road vehicles. Nowadays, family cars do not use mechanical keys to open the fuel tank cap because it is relatively complicated to use. 2. In-car switch method: The in-car switch is currently the most common way to open the fuel tank door, which is certainly more convenient compared to using a key. The in-car switch is located in different positions in different car models, some are on the floor to the left of the driver's seat, some are on the left front door panel or the center console, all marked with a fuel pump icon. However, it should be noted that the in-car switch can easily make the owner forget to turn off the engine before refueling, so the owner should remember to turn off the engine before refueling. 3. Press-to-open method: The press-to-open fuel tank door is currently the most convenient method. The owner only needs to park the car, and the gas station attendant can directly refuel. However, when the owner is not parking to refuel, remember to lock the central control, otherwise the fuel tank cap can be opened.
