You can wash a car engine with water. In fact, the electrical component connectors in the engine compartment are waterproofed and not afraid of water. However, car owners should pay attention to the following points during daily use: 1. Do not wash with water when the engine is hot. If cold water is used to wash the engine when it is at a high temperature, the sudden temperature change may cause the machine to crack or even damage internal circuits; 2. Try to avoid the external fuse box, as using a high-pressure water gun may pose risks; 3. Use an air gun for cleaning. An air gun, commonly available at repair shops, can be used by maintenance personnel to clean the engine. Sometimes, cleaning with an air gun can be even more effective than using water, and more importantly, it protects the vehicle from water damage to components.

What are China 5 and China 6?

The distinction between China 5 and China 6 in vehicles can be seen from the emission standard letters on the rear of the car. China 5 is denoted by 'V', while China 6 is denoted by 'VI'. The differences between the two are as follows: Different emission standards: The emission standards for China 6 are more than 30% stricter than those for China 5. Excluding the influence of driving conditions and testing, gasoline vehicles under China 6 have a 50% reduction in carbon monoxide emissions, a 50% reduction in total hydrocarbons and non-methane hydrocarbons, and a 42% reduction in nitrogen oxide emissions. Different implementation times: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth phase of the national motor vehicle emission standards. China 6 was implemented starting July 1, 2019. Different principles: Under China 5, the emission standards for diesel and gasoline vehicles were different, but China 6 adopts a fuel-neutral principle, meaning that regardless of the fuel type, the emission limits are the same. Different issuing authorities: The China 5 standard was issued by the Ministry of Environmental Protection, while the China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different letter representations: China 5 is represented by 'V', while China 6 is represented by 'VI'. Different monitoring requirements for plug-in hybrid electric vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including regulations on energy storage systems, thermal management systems, brake regeneration, drive motors, generators, etc. The China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted in normal use, with no driving or license plate restrictions, their resale value will be significantly impacted. For car owners, if they purchase a truck for hauling goods on loan, the depreciation of the vehicle after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, with longer service life and more road rights, have more advantages.

What is the reason why the Audi A4 electric fan keeps running?

Audi A4 electric fan keeps running due to air conditioning compressor failure. Electric fan control method: Unlike engine-driven fans, automotive electric fans need to adjust their working status based on coolant temperature. Some are controlled by the vehicle ECU to operate the electric fan, while others use a thermistor switch. Different cars have different electric fan control methods. Composition structure: Generally, the electric fan assembly includes the electric fan, bracket, temperature sensor, temperature control switch, relay, wiring harness, etc. If the car electric fan does not rotate, the above factors can be checked for troubleshooting.
