Auto start-stop does not harm the engine. The auto start-stop is a hot start, and the engine mainly relies on oil film lubrication inside. Since the auto start-stop duration is very short, the oil pumped up by the oil pump will not completely flow back, and a significant amount of oil remains on the components. Therefore, frequent starts do not cause much wear to the engine. An engine is a machine that converts other forms of energy into mechanical energy, which can refer to either the power generation device or the entire machine including the power unit. Engine lubrication is achieved by the lubrication system, whose basic function is to continuously supply lubricating oil to the friction surfaces of various components, reducing friction and wear.

Can Hybrid Cars Get Green License Plates in Beijing?

Whether hybrid cars purchased in Beijing can obtain green license plates depends on the vehicle's technical specifications. In Beijing, only pure electric vehicles are eligible for green new energy license plates, while other regions may allow certain hybrid models to obtain green plates based on technical requirements. How hybrid vehicles work: Hybrid systems operate either in parallel configuration where the internal combustion engine serves as the primary power source with an electric motor providing auxiliary power. This system primarily relies on the engine for propulsion, utilizing the electric motor's high-torque advantage during vehicle startup and acceleration when engine fuel consumption is high, thereby reducing overall fuel consumption. Advantages of hybrid cars in Beijing: Hybrid vehicles demonstrate superior fuel efficiency and driving performance. Since the electric motor assists the gasoline engine during acceleration and startup, fuel consumption can be significantly reduced. Hybrid vehicles combine fuel and electric power, featuring an electric motor that assists the internal combustion engine. This technology merges the advantages of gasoline-powered cars and pure electric vehicles, creating complementary benefits that appeal to mainstream markets and environmentally conscious consumers. These vehicles offer reduced fuel consumption, improved fuel economy, and greater environmental friendliness.

Does Flashing ECU Affect Engine Lifespan?

Flashing the ECU will affect the engine's lifespan. After the ECU is flashed, the engine's power will increase, but its service life will inevitably shorten. Disadvantages of ECU flashing: Higher fuel quality requirements: Originally, 92-octane gasoline was sufficient, but after ECU flashing, 95-octane gasoline is required, and fuel consumption will also become abnormally high. Higher engine temperature requirements: Since the engine operates in an overclocked state after ECU flashing, the original cooling system can no longer meet the engine's heat dissipation needs. Excessive engine temperature can cause fatal damage. Issues with maintenance and insurance: Situations such as 4S shops refusing warranty coverage and insurance companies denying claims may arise. Additionally, suitable replacement parts may not be available, leading to higher maintenance costs. Disrupts vehicle balance: Automakers retain 5%-30% of the engine's performance to ensure vehicle balance. The factory tuning is based on a comprehensive consideration of engine lifespan and road conditions. If power parameters are pursued excessively, the vehicle will become less durable and may quickly wear out.

Will the installation of an anti-lock braking system significantly reduce braking distance?

Installing an anti-lock braking system (ABS) can reduce braking distance. During vehicle braking, the system automatically controls the braking force to prevent wheel lock-up, maintaining a state of rolling and sliding (with a slip ratio around 20%), ensuring maximum adhesion between the wheels and the road surface. However, ABS systems have their limitations. In two scenarios, ABS may not provide the shortest braking distance: one is on smooth, dry roads when braking is performed by an experienced driver, and the other is on loose gravel, soft soil, or deep snow-covered surfaces. The anti-lock braking system enhances safety during emergency braking. Without ABS, emergency braking can easily lead to wheel lock-up, rendering the steering wheel unresponsive, thereby increasing the risk of severe consequences. Single-channel ABS typically controls both rear wheels based on the low-select principle. This type of ABS may not fully utilize the adhesion of both rear wheels, so the braking distance might not be noticeably reduced. Additionally, since the front wheels' braking is not controlled, they may still lock up during braking, leaving steering capability unimproved. However, single-channel ABS significantly enhances directional stability during braking by preventing lock-up of the rear wheels.

Will changing the color of car width lights result in a fine?

Changing the color of width lights will result in a fine. Driving a vehicle with unauthorized modifications to lighting settings, appearance, or other technical parameters is considered a traffic violation. According to relevant regulations, this will lead to the confiscation of illegal modifications and a fine. Below are specific details about width lights: 1. Introduction: Car width lights refer to the front and rear position lights. Essentially, clearance lights and width lights are similar. The location of width lights varies depending on the vehicle model. On smaller cars, width lights are commonly referred to as small lights. For larger vehicles, due to their size, the lights on the front and rear sides are called width lights. On trucks, width lights are commonly known as side lights. 2. Function: Primarily used during nighttime driving to indicate the presence of the vehicle and its approximate width, aiding other vehicles in judging during overtaking or meeting. 3. Usage: Must be turned on during nighttime driving (traffic regulations require the simultaneous use of clearance lights and rear position lights at night); Highly recommended to turn on width lights during foggy or rainy weather when visibility is poor, serving as a warning reference for vehicles ahead, behind, and oncoming; Turning on clearance lights during dusk driving helps other drivers see the vehicle more clearly.

Will the air conditioner consume power if it's left on after the engine is turned off?

Leaving the air conditioner on after turning off the engine will consume power. Here are the relevant details: 1. High power consumption: The air conditioning system involves the compressor and blower, and the audio system is also a high-power electrical device. If not turned off before shutting down the engine, these systems will automatically start the next time the car is turned on, placing a heavy burden on the battery and causing wear. This is especially true for car audio enthusiasts who have modified their sound systems, as this increases daily power consumption and puts greater strain on the battery during startup. Therefore, whether it's a temporary stop or a long-term parking, the air conditioner and audio system should be turned off before shutting down the engine. 2. Precautions: Car owners should pay attention to the condition of their car battery, regularly inspecting and maintaining it. With changing driving habits, the number of electrical devices in cars has increased, putting more pressure on the car battery. Without careful inspection and maintenance, the car battery can easily malfunction.
