Winter car starting shake reasons are: 1. Low temperature: The exhaust pipe and oxygen sensor temperature is low, the vehicle ECU cannot obtain accurate data in time, causing errors in ignition and fuel-air mixture control, leading to weakened vehicle power output; 2. Car carbon deposits: Throttle carbon deposits have adhesion, preventing the fuel injection from reaching the required gasoline amount for combustion; 3. Spark plug aging: Different ignition gaps cause power deviations in each cylinder. Solutions for winter car starting shake are: 1. Let the car idle after cold start to allow the temperature to rise; 2. Clean the throttle and fuel injector; 3. Replace the spark plugs.

What brand of tire has a gecko on it?

Tires with a gecko logo belong to the TANSON "Gecko" series tires. 1. Introduction: The "Gecko" series tires utilize a new formula and structural design, effectively combining high grip with wear resistance. This challenges the conventional belief that good grip means poor wear resistance, and vice versa, achieving a perfect balance between traction and mileage. 2. Materials: The "Gecko" series tires are made with solution-polymerized styrene-butadiene copolymer, enhancing dry grip while ensuring sufficient strength and wear resistance. They also incorporate high-surface-area silica fillers and silane coupling agents for reinforcement. Combined with the new copolymer, these materials reduce heat generation and rolling resistance while delivering excellent wet traction performance.

How much fuel can a 48V mild hybrid system save?

48V mild hybrid system can save approximately 20% of fuel consumption. The functions of the 48V mild hybrid system are as follows: Energy recovery: The 48V voltage can meet the requirements for lithium batteries to quickly achieve energy recovery, and the recovered energy can be used for auxiliary driving, etc., reducing the engine load, thereby achieving the effect of reducing fuel consumption and emissions. Collaborative engine operation: During starting and acceleration, the motor can intervene to work collaboratively with the engine, improving power while also reducing fuel consumption, thus allowing for a reduction in engine displacement. Although the motor can drive the vehicle alone, when the battery is sufficiently charged, the motor can maintain cruising speed, and the engine will shut down, saving fuel.

How often should engine oil be changed for sedans?

Sedan engine oil change intervals should be calculated based on the mileage of the oil usage. For vehicles using mineral oil, it is recommended to change every 4,000 to 5,000 kilometers; for semi-synthetic oil, every 5,000 to 7,500 kilometers; and for full synthetic oil, every 7,500 to 10,000 kilometers. If frequently driving under harsh road conditions, the oil change interval should be appropriately advanced. Engine oil, also known as engine lubricant, serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption, earning it the reputation as the 'blood' of automobiles. Engine oil consists of two main components: base oil and additives.
