Reasons for Car Shaking When Cold but Normal When Warm

Severe shaking when the car is cold but normal when warm could be due to inaccurate air-fuel mixture ratio. ECU Judgment: If the car's ECU makes an incorrect judgment, it may cause errors in controlling the air-fuel mixture and ignition timing through the actuators, thereby reducing the vehicle's power output and resulting in shaking. Low Temperature: At low temperatures, the engine's internal temperature is insufficient, so more fuel should be injected during cold starts to meet power requirements. The larger the spark plug gap, the smaller the ignition energy. Poor fuel atomization at low temperatures can cause the car to shake. Coil Aging: Aging ignition coils, aging spark plug high-voltage wires, or electrical leakage can also lead to reduced ignition energy.

What is the wear resistance index of Dunlop LM705?

Dunlop LM705 has a wear resistance index of 0.35. Advantages: Good stability and handling, quiet, comfortable. The tread incorporates various high-tech features, with rigidity improved from inside to outside, effectively enhancing stability and handling. Additionally, it adopts a five-pitch irregular tread pattern design for noise reduction. Dunlop: Dunlop LM705, as an upgraded replacement for Dunlop LM703, not only optimizes the tread's rim but also features a refined tread pattern design. This ensures the tread maintains a circular shape upon initial contact, providing certain noise reduction effects and suppressing vibration sensations (when the tire contacts the ground).

What Happens When a Car's Solenoid Valve Fails?

Failure of a car's solenoid valve can affect normal driving operation. Specific symptoms: Engine idle speed fluctuates unstably between high and low, with poor acceleration; gear shifting causes jerking; engine is prone to stalling or difficult to start; air conditioning usage leads to stalling and other fault conditions. Check for poor power connection; verify power voltage is outside operational range; coil desoldering; coil short circuit; improper working pressure difference; excessive fluid viscosity; excessively high frequency; or reached service life. Solenoid Valve: Automotive solenoid valves are actuators in electronic control systems. By function, they can be categorized as shift solenoid valves, lock-up solenoid needle valves, and pressure regulating solenoid needle valves. By operation mode, they are classified as on-off solenoid valves and pulse-width modulated solenoid valves.

Does Clay Bar and Waxing Damage Car Paint?

Clay bar and waxing do not damage car paint. Functions: Waxing serves to waterproof, protect against acid rain, high temperatures, and UV rays. The thin film formed by wax can reflect some light, effectively preventing paint aging. Additionally, car wax can reduce static electricity, which means less dust adhesion, and it also provides a glossy finish, making the car look newer and more attractive. Reasons: Waxing and glazing themselves do not harm the car paint; instead, they offer better protection. However, many irresponsible car detailing shops frequently polish the paint during waxing and glazing processes to achieve an immediate glossy effect, which naturally thins the paint layer over time.

Can only the owner drive an operating vehicle?

Any driver with a road transport professional qualification certificate can drive it. Regulations: Generally, any driver with a road transport professional qualification certificate can drive an operating vehicle. Operating vehicles and operators are separate. The vehicle's operating permit and the road transport professional qualification certificate are not bound in any way and can be used freely. Operating vehicle: A vehicle approved by the relevant authorities to participate in operations. If not approved by the relevant authorities, the vehicle is not allowed to operate, which constitutes illegal operation, an unlawful act.

Does Car Air Conditioning Drip Water?

It is normal for a car to drip water when the air conditioning is on. Reasons: The car's air conditioning system has a component called an evaporator installed inside the dashboard. When the air conditioning is turned on, the surface temperature of the evaporator becomes very low. The moisture in the hot air inside the car condenses on the heat-absorbing fins of the evaporator. The water droplets are collected by the plastic housing of the evaporator and discharged outside the car through a pipe, which is why water drips. Precautions: If the air conditioning is too cold, moisture in the air may condense on the outside of the vents, creating a phenomenon where white mist appears. Moisture in the air may also condense on the plastic housing of the evaporator or the surface of the plastic pipes that deliver cold air, resulting in dripping water. Additionally, this can happen if the air humidity inside the car is too high.
