Why does the automatic transmission car jerk when shifting gears?

Automatic transmission cars may jerk when shifting gears mainly due to vibrations from gear engagement or thick transmission gear oil. The jerking can be divided into two scenarios: front body shaking and rear body shaking. Vibrations from gear engagement: If the front body shakes when shifting gears in an automatic transmission car, it is caused by vibrations from gear engagement, which is normal. In automatic transmissions, the onboard computer controls gear shifts. When the driver issues a shift command, the computer automatically shifts gears as long as the RPM is within a reasonable range, which can produce vibrations. In contrast, manual transmission drivers can control the clutch to reduce the sensation of vibration. Thick transmission gear oil: If the rear body shakes when shifting gears in an automatic transmission car, it is due to thick transmission gear oil with high density. The drivetrain receives engine power more noticeably, causing the rear body to shake visibly. When the car is in motion, the transmission gear oil temperature rises, thinning the oil and eliminating the shaking.

What should the engine RPM be at 80 mph?

The engine RPM should be maintained between 2000-2500 when driving at 80 mph. For a 1.4T displacement engine, an engine speed of around 2000 rpm is normal, while the idle speed typically ranges between 700 rpm and 1000 rpm. The effective power output of the engine varies with different RPM levels, meaning the engine's effective power is closely related to its rotational speed. The maximum power calibrated before the engine leaves the factory is not the absolute maximum power the engine can produce, as the maximum effective power of an engine has its limits. Even for the same engine model, the power output may differ based on the vehicle's intended use. When starting the car in first gear, the engine RPM generally stays around 1000-1500 rpm. In second gear, it maintains around 1500-2000 rpm. Similarly, in third and fourth gears, the RPM remains between 1500-2000 rpm. When driving at high speeds in fifth gear, the engine RPM typically ranges from 1500-3000 rpm.

Is it permissible not to affix the Chongqing Traffic Information Card electronic tag?

It is not permissible to omit affixing the Chongqing Traffic Information Card electronic tag; it must be affixed to the windshield. Below is relevant information regarding the Chongqing Traffic Information Card: 1. Introduction: Motor vehicles that have obtained a locally issued vehicle license should collect the motor vehicle traffic information card from the vehicle management office of the public security traffic management department and affix it to the upper middle part of the front windshield where it does not obstruct the driver's view. For vehicles without a windshield, it should be affixed to an appropriate location at the front of the vehicle. Drivers who have obtained a locally issued motor vehicle driving license should collect the driver traffic information card from the vehicle management office of the public security traffic management department and carry it with them while driving. 2. Notes: The Chongqing Traffic Information Card must not be lent or used by others. If the traffic information card has not been collected or is lost or damaged, it should be re-collected from the vehicle management office of the public security traffic management department by presenting the motor vehicle driving license or vehicle license.

What Causes the Steering Wheel of Volvo S60 to Make Abnormal Noises When Turning?

Volvo Asia Pacific S60 steering wheel abnormal noise when turning reasons are as follows: 1. Friction between plastic components inside the steering wheel: Especially in winter, since most parts inside the steering wheel are made of plastic, the plastic hardens as the temperature drops, making it prone to abnormal noises and static electricity during friction. 2. Damage or excessive clearance of the steering tie rod ball joint: This situation usually causes steering wheel vibration and abnormal noise when turning. It is recommended to replace the tie rod ball joint or the entire tie rod assembly, followed by a four-wheel alignment to adjust the parameters. 3. Internal damage to the power steering gear: If you noticeably feel that the steering effort is heavier or less smooth than before when turning, accompanied by abnormal noise, it may be due to internal damage to the power steering gear, often caused by excessive wear and clearance of the meshing gears inside the steering gear. This condition cannot be repaired; it is recommended to replace the entire steering gear assembly.

What is the cost per kilometer for a combined fuel consumption of 6.2L/100km?

With a combined fuel consumption of 6.2L/100km, the cost per kilometer is approximately 0.48 yuan. Here is some relevant information about fuel consumption: Fuel consumption per 100 kilometers: Fuel consumption per 100 kilometers refers to the amount of fuel consumed by a vehicle traveling 100 kilometers at a certain speed on the road. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is obtained by manufacturers under objective conditions using a dynamometer installed on the vehicle's chassis to measure values, which are then converted into speed parameters. The vehicle is then driven at specified speeds to calculate the theoretical experimental fuel consumption data per 100 kilometers for the model. Road condition fuel consumption: Road condition fuel consumption is a fuel indicator calculated based on repeated tests of a vehicle traveling at specified speeds and times on designated roads, also known as multi-condition road cycle fuel consumption.

What are the driving modes of the Elantra?

The Elantra offers three driving modes: Sport Mode, Eco Mode, and Standard Mode. Below are the relevant introductions: Standard Mode: This mode prioritizes driving comfort as the primary premise. Its characteristic is that once activated, it provides excellent stability. The engine and transmission operate under optimal conditions. Eco Mode: This mode is suitable for urban road driving and is also known as the fuel-saving mode. Automatic transmissions generally consume more fuel than manual transmissions. The working principle of this mode is to reduce the engine's output power to lower fuel consumption, thereby improving fuel economy. This mode limits power output, resulting in insufficient power during uphill driving, uneven road conditions, and acceleration. Prolonged use may lead to engine carbon buildup, which can increase fuel consumption in the future. It is not recommended to keep this mode on for extended periods. Sport Mode: The characteristic of this mode is its intelligence. It automatically switches to the appropriate mode based on road conditions, vehicle speed, and driving habits.
