Can the car engine compartment be washed?

The car engine compartment can be cleaned. Here are the precautions for cleaning the engine compartment: 1. The car's engine compartment undergoes very strict waterproof treatment before leaving the factory. Therefore, many 4S shops or repair shops will directly rinse it with water. It should be noted that you must wait until the car engine cools down before washing, because after prolonged operation, the engine temperature is very high. If cold water is used for rinsing, it may cause the car engine to crack. 2. Do not use a high-pressure water gun to rinse the fuse box. Although the car undergoes waterproof treatment when leaving the factory, facing the high-pressure water gun rinse, the fuse box may leak electricity or short-circuit. 3. After several years of car use, due to aging wiring issues, it is necessary to go to a specialized engine cleaning repair shop for maintenance.

According to Article 16 of the "Regulations for the Implementation of the Road Traffic Safety Law": The vehicle inspection requires the following documents: the vehicle's driving license, valid compulsory insurance policy, the owner's ID card, and all traffic violation records must be cleared in advance. Safety technical inspections should be conducted within the following periods: Commercial passenger vehicles: once a year within 5 years; once every 6 months after exceeding 5 years. Trucks and large/medium non-commercial passenger vehicles: once a year within 10 years; once every 6 months after exceeding 10 years. Small/mini non-commercial passenger vehicles: once every 2 years within 6 years; once a year after exceeding 6 years; once every 6 months after exceeding 15 years. Motorcycles: once every 2 years within 4 years; once a year after exceeding 4 years. Tractors and other vehicles: once a year. Commercial vehicles must undergo annual inspection within the specified period. Vehicle inspection mainly includes the following items: Appearance inspection: mainly checking vehicle lights, body appearance, suspension, sunroof, and tires. It verifies if lights are functioning properly, if the body color has been changed, and if the suspension has been modified. Emission test: checks whether the vehicle's tailpipe emissions meet national standards during high-speed operation. On-line inspection: mainly examines the vehicle's braking system, headlights, horn, and chassis. Violation check: all traffic violation records must be cleared before the inspection to pass.

What is the working principle of hybrid vehicles?

Hybrid electric vehicles operate by using an electric motor as an auxiliary power source to assist the engine in driving the car. Here are the specific details about how hybrid vehicles work: 1. When the battery charge drops below sixty percent, the auxiliary power system activates. When the vehicle's energy demand is high, both the auxiliary power system and the battery pack supply energy to the drive system. When the energy demand is low, the auxiliary power system not only provides energy to the drive system but also charges the battery pack. 2. Examples of hybrid vehicles include the Lynk & Co 01, BYD Song, BYD Qin, BYD Qin Pro, and BMW 7 Series. Taking the BMW 7 Series as an example, it is classified as a full-size car with the following dimensions: length 5250mm, width 1902mm, height 1498mm, wheelbase 3210mm, fuel tank capacity 46 liters, trunk capacity 420 liters, and curb weight 2190kg.

What is the fuel consumption of the Geely Boyue Pro 2021 model?

Geely Boyue's combined fuel consumption is 7.1-7.7L/100km. Currently, there are 8 models of Geely Boyue available for sale. The manual two-wheel-drive Asian Games Edition has a combined fuel consumption of 7.1L/100km. The two-wheel-drive Comfort Edition, two-wheel-drive Asian Games Comfort Edition, Supreme Edition, Smart Connection Edition, Smart Edition, two-wheel-drive Asian Games Edition, and Smart Leader Edition have a combined fuel consumption of 7.7L/100km. The above figures are NEDC combined fuel consumption, which is the fuel consumption data measured under the NEDC test procedure. The actual fuel consumption is higher than this value, ranging from 8.3-10.0L/100km. When driving, the following five tips can help reduce fuel consumption: During vehicle start-up, use a low gear to start, gently press the accelerator, and gradually increase speed. Avoid suddenly pressing the accelerator hard, as this can multiply fuel consumption. Gentle acceleration and braking, early braking: When driving, gently press the accelerator to avoid sudden increases in engine speed and prevent the car from shaking during operation, thereby making the car more fuel-efficient. By anticipating road conditions and applying slow and uniform acceleration or braking, fuel economy can be improved by up to 20%. Maintain proper tire pressure: Keep tire pressure at the level recommended by the manufacturer. For every 2 PSI below the recommended value (equivalent to about 0.2 in metric units relative to the standard pressure of 2.4), fuel consumption increases by 1%. Regular maintenance or vehicle inspection: Timely oil changes can reduce carbon deposits (carbon deposits can cause ignition issues, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). Regularly check and replace the air filter when dirty, and clean or replace the fuel injectors, spark plugs, and throttle body as per mileage. Close windows while driving. Driving with windows open increases wind resistance. The greater the wind resistance, the more resistance the car faces, requiring more power and thus increasing fuel consumption.
