The reasons for severe shaking of the Changan CS35 when the air conditioning is turned on are throttle valve blockage, excessive carbon buildup, and aging of the shock absorption system. Details are as follows: Throttle valve blockage: Throttle valve blockage affects the engine. If the air conditioning is turned on at this time, it will increase the engine idle load, resulting in vehicle shaking. The solution is to clean the throttle valve. Excessive carbon buildup: Severe carbon buildup in the engine cylinders can cause spark plug blockage or throttle valve blockage. Once the air conditioning is turned on, it will directly lead to shaking during idle. The solution is to clean the engine. Aging shock absorption system: The shock absorption system is mainly responsible for filtering the vibrations generated during engine operation. If there is an issue with the shock absorption system, these vibrations will be directly transmitted to the steering wheel and the interior of the vehicle, affecting driving. When the engine is idling, turning on the vehicle's electrical systems can also easily cause shaking. The engine increases its load due to the activation of electrical systems, causing the idle speed to drop. To compensate for the shaking caused by the drop in idle speed, the engine will automatically increase the RPM. Therefore, when electrical systems, especially the air conditioning, are turned on, the engine often shakes. This shaking is likely caused by aging shock absorbers and requires timely replacement.

What is the highest fuel consumption for a CVT motorcycle?

The highest fuel consumption for a CVT motorcycle is three liters. The principle of CVT: The continuously variable transmission on scooters is generally a belt-type clutch (also called a clutch because it serves the dual function of connecting and disengaging the engine's power to the drive wheel, though it differs from the multi-plate wet-type constant-mesh clutch found in conventional motorcycles). It consists of a front driving pulley, a rear driven pulley, and a belt. This system also functions as a clutch. In this setup, the driving pulley rotates at the same speed as the engine output shaft. At idle, the friction plates of the rear driven pulley do not engage with the friction bowl, preventing the bike from moving forward. When the engine speed increases, the two components engage, transmitting the engine's driving force to the rear driven pulley, which propels the bike forward. Fuel-saving tips for CVT motorcycles: Speed: Generally, maintaining a speed of 40-50 km/h with an engine speed of 3,500-4,200 RPM is the most fuel-efficient. Fuel consumption increases significantly at speeds below 25 km/h or above 75 km/h. Riding habits: Aggressive acceleration or competing for quick starts greatly increases fuel consumption. Steady-speed riding saves fuel, while frequent speed changes consume more. When accelerating, do so gradually—avoid forcefully opening the throttle and then releasing it, as this wastes fuel. Road conditions: Hilly or winding roads, frequent traffic lights, and poor road surfaces increase fuel consumption, while straight, smooth asphalt roads are the most fuel-efficient.

What Causes the Engine Warning Light to Illuminate on the Lynk & Co 06?

There are primarily 7 reasons why the engine warning light may illuminate on the Lynk & Co 06: Sensor Malfunction: The sensors in question include those for coolant temperature, crankshaft position, air flow, intake temperature, and oxygen sensors. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which triggers the engine warning light. Fuel or Oil Quality Issues: Failure to use the fuel or engine oil as specified by the manufacturer may cause engine wear, leading to the illumination of the warning light. Poor Combustion of Air-Fuel Mixture: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as an alert. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all lead to poor combustion of the air-fuel mixture. Turbocharger Problems: The intake boost piping or turbocharger can also cause the engine warning light to come on. The most common issue is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If the vehicle's air intake is compromised, it may lead to clogged engine piping, and in severe cases, trigger the engine warning light. A dirty air filter that hasn't been cleaned regularly can cause intake issues. Exhaust Problems: Exhaust system faults can also cause the engine warning light to illuminate. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequent culprit, often affected by the use of leaded gasoline, lead- or silicon-based lubricant additives, physical damage, or fuel system malfunctions. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system fails or if there's a mismatch between the anti-theft controller and the engine ECU, the anti-theft system can prevent the engine from operating normally, accompanied by the illumination of the engine warning light. If the engine warning light comes on, follow these steps: First, check if the engine is running normally. Look for signs like shaking or black smoke. If present, avoid restarting the engine. Note: Never restart the engine if the red warning light is on. If the engine can be started, turn it off and wait 5-10 minutes. Then, without pressing the brake, press the start button once or turn the key halfway to the 'ON' position without depressing the clutch. The vehicle will enter self-diagnosis mode upon powering up. Wait 5-10 seconds to see if the warning light turns off. If the light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the error codes, identify the issue, and perform targeted repairs.

Is it necessary to add Kunlun Mountain gasoline additive?

Whether it is necessary to add Kunlun Mountain gasoline additive depends on the condition of the vehicle. Generally, new cars do not need it. When to add: If the car has been used for a long time, it can be considered to add the additive to improve engine performance. It can also be added when the fuel quality is not very good to enhance the car's power. Functions of gasoline additive: Gasoline additive can improve combustion efficiency and reduce fuel consumption. It can also help decompose and break down deposits in the combustion chamber while preventing future buildup. A clean combustion chamber allows the engine to operate more comfortably, significantly reducing nitrogen oxide emissions and enabling operation with lower-octane fuel.

Can I Drive Someone Else's Car on the Highway?

As long as the driver's license has been held for at least one year, they can drive on the highway. Conditions for driving on the highway: New drivers who have held their license for one year can drive alone on the highway. Those who have held their license for less than one year must be accompanied by a driver who has held their license for at least three years. Probation period for driver's license: The probation period for newly issued or upgraded driver's licenses is twelve months. During this period, drivers cannot drive alone on the highway and must be accompanied by a driver who has held a license for at least three years for the same or a higher vehicle class. New drivers driving alone on the highway will be fined. If a traffic accident occurs, they will bear full responsibility, and the insurance company has the right to refuse compensation. It is very dangerous and illegal for new drivers to drive on the highway, so avoid driving on the highway before the probation period ends.

Is it acceptable to perform maintenance every 7,000 kilometers after the new car reaches 40,000 kilometers?

It is acceptable to perform maintenance every 7,000 kilometers after the new car reaches 40,000 kilometers. Normally, the engine oil performs best at around 7,000 kilometers. The maintenance manual suggests 5,000 kilometers, which can be understood as a general maintenance range. The specific maintenance interval depends on the vehicle's usage. Engine oil and oil filter maintenance are required: Engine oil and oil filter maintenance are necessary because after prolonged driving, both the oil and filter accumulate contaminants. To ensure the proper functioning of the lubrication system, both the engine oil and filter need to be replaced. Spark plug replacement is required: Spark plugs should be replaced approximately every 20,000 kilometers. The reason for this frequent replacement is that spark plugs are consumable parts. To prevent any ignition issues, it is essential to maintain them when the vehicle reaches 40,000 kilometers.
