When the SVS light in a car is on, it indicates that the electric vehicle's ECU computer or TCU computer has detected a fault in the engine or automatic transmission. The SVS warning light signals that the engine control unit has identified an issue with one of the vehicle's sensors, requiring immediate inspection. If the SVS light is illuminated, you can attempt to start the engine. If the engine fails to start, it might be due to a malfunctioning fuel pump that cannot supply fuel properly to the engine. If the engine starts, the problem could be with other sensors. In this case, the vehicle may still be drivable, but the fault could potentially affect normal operation, leading to issues such as increased fuel consumption or engine vibration.

Does Snowmelt Agent Harm Cars?

Snowmelt agent can harm cars as it corrodes the car paint. Car paint is a protective film sprayed onto vehicles, serving as a type of coating that makes the car body less susceptible to corrosion while also providing an aesthetic appeal. Different types of car paint produce different effects, and the quality of the paint itself, along with the technology and a good painting environment, is crucial. Car paint is mainly divided into: standard paint, whose main components are resin, pigment, and additives; metallic paint, which contains aluminum powder, giving it a shiny appearance when applied; and pearl paint, which incorporates mica particles for a sparkling effect. If metallic paint is combined with a clear coat layer, the paint appears particularly dazzling.

What is the working principle of a motorcycle ignition system?

Motorcycle ignition system works by coordinating with sensors to determine the spark timing (also known as ignition timing) for the spark plug. When the high-voltage coil amplifies the voltage and supplies it to the spark plug for ignition, the spark ignites the air-fuel mixture, causing combustion. This combustion drives the piston to move up and down within the cylinder, thereby starting the motorcycle engine. Motorcycles are gasoline-powered vehicles with two or three wheels, steered by handlebars for front-wheel turning. They are lightweight, agile, and fast, widely used for patrol, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles can be categorized into street bikes, sport bikes, off-road motorcycles, cruisers, and tourers.

What are the three major types of new energy vehicle batteries?

Below are the three major types of new energy vehicle batteries: 1. The first type: NCM ternary lithium batteries (represented by manufacturer "CATL"). 2. The second type: NCA ternary lithium batteries (represented by manufacturer "Panasonic"). 3. The third type: The last type is lithium iron phosphate batteries (represented by manufacturer "BYD"). Below is extended information on the characteristics of new energy vehicles: 1. Hybrid vehicles: Equipped with batteries that can conveniently recover kinetic energy during downhill driving. In urban areas, the internal combustion engine can be shut off, allowing the battery to drive alone, achieving "zero" emissions. 2. Pure electric vehicles: Relatively simple and mature technology, they can be charged wherever there is a power supply. 3. Fuel cell vehicles: Zero or near-zero emissions, reducing water pollution caused by oil leaks, lowering greenhouse gas emissions, and operating smoothly with no noise.

Why Does the Steering Wheel Shake When Braking in a Truck?

Here are the specific reasons for steering wheel shaking when braking in a truck: 1. Wheel Balancing Issue: The wheel consists of a tire and a rim. When there's a problem with wheel balancing, it means the wheel isn't in a balanced state during high-speed driving. If the balancing data is incorrect, the wheel's rotation center will shift, causing the wheel to vibrate, which in turn affects the steering wheel. 2. Rim Problem: If the rim has suffered impacts during previous driving, it may become deformed. Due to the deformation of the rim, the wheel may vibrate during driving, leading to steering wheel shaking. 3. Chassis Component Issue: This generally occurs in vehicles with poor post-accident repairs. The impact during an accident can affect chassis components, also resulting in steering wheel shaking.

Why was the Toyota Land Cruiser discontinued in China?

Sales were relatively low. The main reason for an automaker to continue producing a vehicle over the long term is sustained sales support. Additionally, it's worth noting that the Land Cruiser is currently only discontinued in the Chinese market and remains available overseas. Below is more information about the Land Cruiser: 1. Overview: The Land Cruiser, known as the LAND-CRUISER 200 by Toyota, is an imported ORV off-road vehicle produced by Toyota. 2. Specifications: Overall dimensions are 5170*1980*1890, featuring a 5-door, 8-seat SUV configuration with a wheelbase of 2850mm, minimum ground clearance of 230mm, and a total fuel tank capacity of 93L + 45L.

Is the Superb equipped with a dry or wet clutch?

280 models use the DQ200 dry clutch, while 330 and 380 models use the DQ380 wet clutch. Here is relevant information: 1. Dual-clutch transmission: Dual-clutch transmissions are divided into dry and wet types. Wet dual-clutch transmissions have higher costs and larger volumes, but they can effectively prevent transmission overheating, handle greater horsepower output, and are more suitable for urban congested road conditions. Dual-clutch transmissions have minimal power loss during transmission, are more fuel-efficient than manual transmissions, and ensure no power interruption during gear shifts, maintaining both power performance and handling. 2. Dry dual-clutch transmission: During gear shifts, the two sets of clutch systems work together to make shifts smoother, ensuring driving control and power performance. Despite the obvious advantages of dual-clutch systems, dry dual-clutch transmissions have a slightly higher failure rate compared to other automatic transmissions.
