How is the Performance of E-CVT Transmission?

What is the difference between learning C1 and C2 driving licenses?

Differences between learning C1 and C2: 1. Permitted vehicle types: C2 permits driving small and mini automatic passenger cars, as well as light and mini automatic trucks; C1, in addition to the vehicles permitted by C2, also allows driving specialized mini, small, and light-duty vehicles. Simply put, C2 only allows driving automatic transmission vehicles, while C1 permits both automatic and manual transmission vehicles, offering a wider range of permitted vehicle types. 2. Learning cost: Many people think that the C1 license is harder to obtain, so it should be more expensive than C2. The opposite is true because automatic transmission vehicles are more expensive than manual ones, and their maintenance costs are higher, so the registration fee for learning C2 is generally higher than that for C1. 3. Operation difficulty: C1 corresponds to manual transmission, involving complex operations like gear shifting and clutch control, especially during hill starts and traffic light starts, where stalling is common; C2 corresponds to automatic transmission, without a clutch pedal, only brake and accelerator pedals, eliminating concerns about stalling.

What Are Some Tips About New Energy Vehicles?

New energy vehicles refer to automobiles that utilize new power systems and rely entirely or primarily on new energy sources for propulsion, mainly including pure electric vehicles, plug-in hybrid electric vehicles, and fuel cell vehicles. Types of New Energy Vehicles: New energy vehicles mainly include hybrid electric vehicles, compressed natural gas and liquefied natural gas vehicles, coal-driven vehicles, and biomass energy-driven vehicles. Currently, the main models in mass production are pure electric vehicles, plug-in hybrid electric vehicles, and non-plug-in hybrid electric vehicles. Principles of New Energy Vehicles: Generally, traditional vehicles rely on internal combustion engines to convert the chemical energy of gasoline or diesel into kinetic energy. However, the thermal efficiency of internal combustion engines, i.e., automobile engines, is only 0.2-0.4. When combined with processes such as crude oil extraction, refining, and processing, the average energy utilization rate of crude oil is only about 0.14. If the electrical energy converted from new energy sources is utilized, pure electric vehicles can save up to 70% more energy than fuel vehicles, and costs can also be reduced by about 0.5.

How Many Years Does a Car Water Pump Generally Last?

Under normal usage conditions, the lifespan of a car water pump can reach up to 10 years, and generally, it is normal to use it for more than 8 years. More relevant information is as follows: 1. How a car water pump works: The engine drives the water pump bearing and impeller to rotate through the pulley. The coolant in the water pump is driven by the impeller to rotate together, and under the action of centrifugal force, it is thrown to the edge of the water pump housing, generating a certain pressure, and then flows out from the water outlet or pipe. Due to the coolant being thrown out, the pressure at the center of the impeller decreases, and the coolant in the radiator is sucked into the impeller through the pipe under the pressure difference between the water pump inlet and the center of the impeller, achieving the reciprocating circulation of the coolant. 2. Note: The direct consequence of most water pump failures is coolant leakage, mostly due to the aging of the water pump seal. In addition, an overly tight engine combination belt can also cause premature wear of the water pump. Not replacing the antifreeze for a long time can lead to internal corrosion, eventually causing damage to the water pump.

Why is the oil gauge of a multi-cylinder diesel engine not moving?

The reason why the oil gauge of a multi-cylinder diesel engine does not move is due to a malfunction in the oil pressure gauge. Specific causes for the oil gauge of a multi-cylinder diesel engine not moving: Faulty oil pressure sensor, broken connecting wires, or issues with the engine lubrication system. Once these problems are encountered, it is necessary to diagnose the specific issue and promptly resolve the fault. Methods to troubleshoot the issue: Close the ignition switch, start the engine, and maintain medium-speed operation. If the fuel gauge pointer also points below 0, it indicates a disconnection in the wire from the ignition switch to the fuel gauge's upper terminal. If the oil gauge pointer quickly moves from 0 to 5, it suggests a circuit fault between the oil gauge and the pressure sensor. Ground the oil pressure sensor terminal; if the fuel gauge pointer indicates the corresponding fuel level in the tank, use a screwdriver to ground the oil pressure sensor terminal. If the oil gauge pointer remains below 0, it may indicate a disconnection between the fuel gauge's upper terminal and the oil gauge, a damaged oil gauge, or a broken wire between the oil gauge and the oil pressure sensor. Once the problem is detected, proceed with repairs promptly to restore the oil gauge's display.

Do car brakes only stop the front wheels?

Braking involves both the front and rear wheels, with the braking force generally being greater on the drive wheels than on the non-drive wheels. Therefore, in most front-wheel-drive cars, the front wheels provide the primary braking while the rear wheels assist, and the handbrake operates on the rear wheels. If braking is applied only to the front wheels, it may cause the vehicle to lose directional control, making it difficult to maintain the intended path during braking. If braking is applied only to the rear wheels, it may cause the rear wheels to lose traction, potentially leading to skidding or fishtailing. More related information is as follows: 1. The functions of the braking system are as follows: The braking system forces a moving car to decelerate or even stop as required by the driver; it keeps a parked car stable under various road conditions (including on slopes); and it maintains a stable speed for a car moving downhill. 2. Note: Many domestic car manufacturers use front disc and rear drum braking systems for small and medium-sized production vehicles, while some models feature four-wheel disc brakes. Compared to drum brakes, disc brakes are more advanced in technology, lighter in weight, and superior in heat dissipation, braking performance, and adaptability to complex weather and road conditions.

How to Maintain a Car That Hasn't Been Driven for a Year?

Maintenance methods for a car that hasn't been driven for a year: 1. Loosen the ground wire of the battery and reconnect it when in use to ensure no power loss. Additionally, change the engine oil and oil filter every 5,000 kilometers. If the car has been parked for half a year, these should also be replaced. Brake fluid and gear oil should be completely replaced every three years. 2. If possible, it's best to store the car in a garage. If parked in an open area, at least cover the car with a car cover. When choosing a car cover, opt for a thick, multi-layered one to effectively reduce the impact of sunlight on the paint. Ensure the car cover fits properly to avoid unnecessary friction on the paint caused by wind. 3. Tighten all connections on the car. Due to vibrations, bumps, and swaying during driving, connections may become loose or worn. Therefore, regular tightening during maintenance is essential. The routine tightening of connections is directly related to driving safety, especially for critical components like steering, braking, and transmission systems, which should never be overlooked.
