What Causes Throttle Vibration in a Car?

Reasons for throttle vibration in a car: 1. The engine mount rubber is leaking oil or has aged and cracked, significantly reducing its shock absorption effect, thus causing the throttle pedal to vibrate; 2. Clutch slippage. In manual transmission and dual-clutch models, the power transfer and disconnection between the engine and the transmission are accomplished by friction plate clutches. If the clutch plates are severely worn or the damping springs are broken, it will cause the throttle pedal to vibrate. Modern cars use electronic throttle bodies instead of the old cable-type throttle bodies, which means there is no physical connection between the throttle pedal and the throttle body. If you feel the throttle pedal vibrating when pressing the accelerator, it is mostly due to engine resonance transmitted through the car body to the throttle pedal, making the driver feel the vibration when placing their foot on the pedal. This vibration sensation is particularly noticeable during acceleration, and prolonged exposure can cause numbness in the foot.

What is the normal temperature range for the transmission oil in a Haval H6?

Haval H6 transmission oil temperature generally should not exceed 120°C, with 80°C or 90°C being the optimal range. Prolonged exposure to temperatures above this range will accelerate the degradation of transmission oil components and reduce its usability. At the normal operating temperature of 80°C, every 10°C increase in temperature will halve the service life of the automatic transmission oil. The hazards of excessively high transmission oil temperature are as follows: 1. High temperatures can degrade the quality and frictional characteristics of automatic transmission oil, increasing friction and wear, leading to transmission noise. Additionally, sludge (impurities or contaminants) may form inside the transmission (e.g., in the valve body), causing jerking or impact during gear shifts. 2. If the temperature exceeds 120°C, rubber sealing materials will begin to harden and age, leading to leaks due to poor sealing and ultimately resulting in reduced hydraulic pressure. If the temperature rises even higher, the transmission may start to slip, and this slippage can, in turn, cause the temperature to rise further.

What are the benefits of engine oil?

The benefits of engine oil include: 1. A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear; 2. Engine oil can form a sealing ring between the piston ring and the piston, reducing gas leakage and preventing external contaminants from entering; 3. Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases; 4. When the pressure in the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load; 5. It can carry away carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and flush away dirt generated on the working surfaces of parts through the flow of the lubricating oil.

What Are the Differences Between the Envision and the Encore?

The differences between the Envision and the Encore can be summarized in the following 5 points: 1. Vehicle positioning is different: The Encore is a compact SUV, while the Envision is a midsize SUV. 2. Pricing varies: The Encore is priced between 140,000 to 190,000 RMB, while the Envision is expected to be priced between 250,000 to 350,000 RMB. 3. Powertrain differences: The 2019 Buick Envision National VI version comes in two models: The 20T model is equipped with a newly tuned 1.5T SIDI direct-injection turbocharged engine paired with an upgraded 7-speed DCG dual-clutch transmission, delivering a maximum horsepower of 169 PS, a maximum power of 124 kW, and a maximum torque of 250 N·m. The 28T model continues to use a 2.0T SIDI direct-injection turbocharged engine, matched with a 9-speed automatic transmission, producing a maximum horsepower of 260 PS, a maximum power of 191 kW, and a maximum torque of 400 N·m. In contrast, the Encore is equipped with a 1.4T turbocharged engine, delivering a maximum power of 105 kW (143 PS) and a maximum torque of 205 N·m, paired with either a 6-speed manual or a 6-speed automatic transmission. 4. Different configurations: The Encore comes standard with Buick's next-generation eConnect intelligent connectivity technology, featuring the Baidu CarLife in-car system and intelligent voice recognition, while the Envision does not. 5. Exterior design differences: The Envision's front fascia does not use the bold lines seen on its larger siblings but instead features more rounded contours, whereas the Encore adopts Buick's signature winged grille design.

Why is U-turn prohibited at railway crossings?

Reasons for prohibiting U-turns at railway crossings: Making a U-turn at a railway crossing can easily cause traffic accidents. According to relevant regulations, motor vehicles are not allowed to make U-turns at locations with no U-turn or no left-turn signs or markings, as well as at railway crossings, pedestrian crossings, bridges, sharp curves, steep slopes, tunnels, or other dangerous sections of the road. Motor vehicles can make U-turns at locations without no U-turn or no left-turn signs or markings, but they must not obstruct the passage of other normally moving vehicles and pedestrians; at locations where U-turns are permitted and special U-turn traffic lights are installed, U-turns should be made during the green light. If there are no U-turn traffic lights but there are corresponding signs indicating U-turns during red or green lights, the U-turn should be made following the instructions of the signs.

Should I Use Putty or Bondo for Cars?

It is recommended to use putty for cars. Putty consists of A epoxy resin and B polyamide hardener. A common hardening method is to add more hardener when kneading the putty. The chemical method involves using ethylene glycol and acetic acid, but this only theoretically accelerates the curing process of this type of AB epoxy resin. Both putty and bondo are used for repairing models, as well as for creating modifications and custom parts. Before drying, they are used to adhere to the model. Once dried, they become hard. However, bondo is toxic, so it is not recommended unless absolutely necessary. Even when used, it should only be operated in a well-ventilated area while wearing a gas mask.
