What causes jerking in a CVT transmission?

1 Answers

CVT transmission jerking is mainly caused by gear shift hesitation during cold starts. Here are the detailed explanations: 1. Insufficient lubrication: Since most mainstream CVT transmissions require fluid, inadequate lubrication during cold starts may lead to poor chain connection. This makes it easy for clutch engagement to cause impact during cold starts, resulting in gear shift hesitation. This situation can be avoided by properly warming up the vehicle and firmly pressing the brake during gear shifts to ensure smooth clutch engagement. 2. Design and quality issues: Many cases of CVT transmission vibration are caused by design and quality problems, with a certain Japanese brand being a typical example. This brand's CVT failures primarily occur due to poor torque converter design (connecting the transmission body to the engine), causing gear shift impacts that may happen at any speed.

Where is the Low Beam Light Switch Located?

The high/low beam light switch is typically located on the control lever on the lower left side of the steering wheel. Here are the relevant details: 1. Function: When driving on urban roads, highways while following other vehicles, or on well-lit road sections, the low beam lights can be turned on. This serves two purposes: first, it allows other drivers to see your vehicle, preventing rear-end collisions, and second, it enhances your own visibility. 2. Illumination Range: The high/low beam icons are represented by a lamp head with ray graphics—horizontal rays indicate high beams, while diagonal rays indicate low beams. Low beam lights project light downward, covering a distance of 12-18 meters in front of the vehicle with a distinct cutoff line between light and dark. Beyond this line, in an area of 30-40 meters, the illumination relies on ground-reflected light, allowing the identification of brightly colored objects within this range.

What is the difference between a flooded car and a water-damaged car?

Here is the relevant introduction to the difference between a flooded car and a water-damaged car: Water-damaged car: A water-damaged car refers to a vehicle that has been submerged in water. Based on the extent of damage, it can be divided into three categories. The first type is when the vehicle's tires are submerged, and water enters the interior. The second type is when the water level exceeds the dashboard. The third type is when the vehicle is completely submerged, exceeding the roof. Flooded car: A flooded car refers to a vehicle that has been driven on low-lying, waterlogged roads, typically occurring during heavy rain when drainage systems are poor, leading to water accumulation on the road. Water-damaged cars, especially those submerged for extended periods, can suffer significant damage to electrical circuits and equipment.

What Are the Reasons for Excessive Consumption of Car Antifreeze?

Car antifreeze can be consumed too quickly due to leaks, damaged cylinder gaskets, aging seals, etc. Here are the specific details: Leaks: Loose or poorly sealed pipe fittings in the cooling system can cause antifreeze leakage, leading to excessive consumption. Damaged Cylinder Gasket: A damaged cylinder gasket allows antifreeze to flow into the cylinders, where it burns off, or into the oil pan, resulting in rapid antifreeze loss. Aging Seals: An aging radiator cap seal can cause antifreeze to deplete too quickly. Here’s some additional knowledge about antifreeze: If antifreeze is insufficient, the engine is prone to "boiling over" during high-speed operation, and the viscosity of the engine oil will decrease. Over time, this can wear down the engine and shorten its lifespan.

Will Water Enter the Car if It Submerges Above the Door?

Water will enter the car if it submerges above the door, but the process is relatively slow. Here are the details: Water ingress speed: When a vehicle is submerged, water will gradually seep in. The interior is temporarily a sealed space, so as long as the doors remain closed, the water ingress will be slow—unless the water level exceeds 50% of the door's steel panel height. The higher the pressure, the faster the water will enter. Of course, the actual speed also depends on the depth of submersion and the duration. Precautions: During heavy rainstorms, turn on all vehicle lights to ensure other drivers can see your car, reducing the risk of collisions. Try not to exceed 40 km/h. Wet roads in heavy rain are usually slippery, making it easier for the vehicle to lose control. Always hold the steering wheel with both hands, maintaining a straight and slow driving speed.

Is CVVT Technology Outdated?

CVVT is considered outdated compared to DVVT, but it is still used in many vehicle models today, proving that its technical characteristics still have a market. Below are specific details about CVVT: 1. Introduction: CVVT, translated into English as Continuous Variable Valve Timing, is one of the many variable valve timing technologies gradually applied to modern cars in recent years. The goal is to match the optimal valve overlap angle (valve timing) under different engine operating conditions, although the methods of achieving this vary. 2. Technology: The CVVT developed by Hyundai Motor is a technology that uses an electro-hydraulic control system to adjust the timing of the camshaft opening the intake valve, thereby controlling the desired valve overlap angle. This technology focuses on the first letter 'C' (Continue), emphasizing continuous adjustment of the valve overlap angle based on the engine's operating conditions, thereby altering the cylinder's air intake volume.

Where is the fourth-level water submersion height for flooded vehicles?

Level four height reaches the middle of the instrument cluster. Below are the precautions for water submersion insurance: Relevant regulations: If engine damage is caused by a secondary ignition attempt in water, even with water submersion insurance, the insurance company will not compensate. Therefore, never attempt to start the car if it has been submerged. Three levels: Flood-damaged vehicles are generally categorized into three levels based on submersion depth. The first is when water reaches the wheel level—such vehicles can still have practical value after repairs. The other two levels are when water reaches the dashboard and when it submerges the roof. These two scenarios are considered severe flood damage, requiring costly repairs with significant potential risks even after fixing, so insurance will typically pay out as a total loss.
