What is the purpose of an LSD?

LSD stands for Limited Slip Differential. This device ensures that power is still transmitted to the other wheel on the same axle when one wheel experiences slippage, thereby improving the vehicle's driving stability and safety. All cars are equipped with a differential, which allows the two wheels on the same axle to rotate at different speeds, aiding the vehicle in cornering. When a car is cornering, the outer wheel travels a longer distance than the inner wheel. To facilitate smooth cornering, the rotational speeds of the inner and outer wheels must differ. If both wheels rotate at the same speed during a turn, it can increase tire wear and even lead to accidents during high-speed cornering.

What does it mean when the DEF light is on in the car?

When the DEF light is on in the car, it indicates that the auxiliary water tank is low on water. If the small odometer on the car dashboard displays "DEF," it means there is an internal processor fault in the dashboard. If the auxiliary water tank is low, it needs to be refilled immediately. If the issue is with the internal dashboard processor, it should be addressed promptly at a local 4S shop. The car dashboard is a device that reflects the working conditions of various vehicle systems. It displays the operational status of different car systems and immediately alerts if there is a problem, using indicator lights to ensure the safety of the occupants. Common indicators include the fuel indicator, washer fluid indicator, electronic throttle indicator, front and rear fog light indicators, and warning lights.

What are the differences between China 6 and China 5 emission standards?

The differences between China 5 and China 6 emission standards are as follows: Different emission standards: China 6 emission standards are more than 30% stricter than China 5. Excluding the influence of working conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: China 5 standards were implemented nationwide on January 1, 2017, as the fifth phase of national motor vehicle emission standards. China 6 was implemented on July 1, 2019. Different principles: During the China 5 phase, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing departments: China 5 standards were issued by the Ministry of Environmental Protection. China 6 standards were 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 energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulatory aspects. 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. They are 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 (particulate matter) 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 (particulate matter) per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted from normal use, such as driving bans or license plate restrictions, their resale value will be significantly impacted. For car owners, if they purchase a truck for freight transport via a loan, the vehicle's depreciation after repaying 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 greater advantages.

What Causes Insufficient Power When Going Uphill?

Reasons for insufficient power when going uphill: 1. If the fuel quality is poor, excessive impurities or water in the fuel can lead to power loss; 2. When climbing a slope, if the gear is set too high, the RPM will naturally struggle to increase. For manual transmission vehicles, it's advisable to shift into gears 1 to 3 depending on the situation; 3. Excessive carbon buildup in the throttle and intake ducts can reduce air intake, preventing complete fuel combustion and directly affecting power output; 4. If the fuel injector is clogged, it can result in poor fuel atomization or even failure to spray fuel, leading to cylinder misfire, reduced engine power output, and insufficient power.

Can a touch-up pen be used to repair exposed primer?

Exposed primer cannot be repaired with a touch-up pen. Touch-up pens are mainly suitable for small scratches, scuffs, and protection of areas where the base color is exposed. If the scratch on the car body has exposed the primer, local touch-up painting is required. For such scratches, it is recommended to go to a paint repair center that offers quick scratch repair services. Before performing touch-up painting yourself, first clean the damaged area. You can use very fine sandpaper dipped in water to gently remove rust spots and wipe it completely clean, then apply a layer of primer to prevent the rust from spreading or worsening. For new scratches, you can wipe them clean and directly apply primer. After the applied primer has dried, use water sandpaper to smooth it out, and then use a touch-up pen for coloring.

What does the flashing 'securlty' light mean?

securlty flashing indicates that the vehicle's anti-theft system is in the locked state. It starts flashing after the car is locked, signaling that the anti-theft function has been activated. The 'securlty' light is a vehicle alarm security indicator. The electronic anti-theft system for automobiles is an electronic security system with functions such as alarm, cutting off the engine ignition circuit, fuel supply, and controlling braking and transmission. The electronic anti-theft system consists of an electronically controlled remote or key, electronic control circuit, alarm device, and actuators. The automotive electronic anti-theft system adds an anti-theft control circuit to the original central locking system to control vehicle movement while sounding an alarm. Electronic anti-theft is currently the most ideal anti-theft device.
