Why Does the Car Shake When the Air Conditioner is Turned On?

Car shaking is caused by carbon deposits on the spark plugs, carbon buildup on the intake valves, or the use of inappropriate fuel. Carbon deposits on the spark plugs: After a period of use, spark plugs can accumulate carbon deposits. If not cleaned in time, this can reduce the engine's torque output, causing the car to shake when the air conditioner is turned on. To clean the spark plugs, soak them in a container filled with white vinegar for 2-3 hours (or 4-5 hours for severe cases), then scrub them with a stiff brush to remove the carbon deposits. Afterward, clean them with gasoline and let them air dry naturally. Carbon buildup on the intake valves: Older cars typically have a normal cylinder pressure of around 10.5, while newer cars have pressures of 11 or higher. If the cylinder pressure is abnormal, the car's computer may detect cylinder misfires and automatically cut off fuel supply, leading to shaking when starting the car until it fails to start. Abnormal cylinder pressure can be resolved by cleaning the carbon buildup on the intake valves. This can be done by driving at high speeds (above 4,000 RPM) to burn off the carbon deposits in the cylinders. Cleaning the intake valves requires removing the intake manifold and manually scrubbing or using cleaning agents to remove the buildup. Use of inappropriate fuel: The fuel octane rating represents the fuel's resistance to knocking. Higher-octane fuel can extend the lifespan of the catalytic converter and reduce emissions. Additionally, engines with different compression ratios require different fuel qualities. Using the wrong gasoline can lead to severe carbon buildup in the engine, causing the car to shake when the air conditioner is turned on. Generally, engines with a compression ratio below 7.5 can use 90-octane gasoline, those between 7.5 and 8.0 should use 90 or 93-octane, those between 8.0 and 10.0 should use 93 or 95-octane, and those above 10.0 should use 97-octane gasoline.

Where is the Fuel Pressure Sensor Located

Fuel pressure sensor is an upgraded version of the fuel pressure regulator. Some vehicle models are equipped with two fuel pressure sensors: one low-pressure fuel pressure sensor and one high-pressure fuel pressure sensor. Low-pressure fuel pressure sensor: The sensor is installed in the fuel inlet pipeline leading to two high-pressure fuel pumps. It measures the fuel pressure in the low-pressure fuel system and sends the signal to the engine control unit. High-pressure fuel pressure sensor: This sensor is used in direct-injection engines. It measures the fuel pressure in the high-pressure fuel system and sends the signal to the engine control unit.

Why is there abnormal noise from the right front wheel?

The causes of abnormal noise from the right front wheel include steering gear jamming during the steering process, damage to the stabilizer bar bushing, and issues with the left front shock absorber top mount. Steering gear jamming: The abnormal noise occurring during the steering process is caused by steering gear jamming. Stabilizer bar bushing damage: Abnormal noise on bumpy roads is caused by damage to the chassis suspension bushings or friction from a loose front bumper. Outer CV joint damage: For abnormal noise from the right front wheel, the outer CV joint can be replaced, or a four-wheel alignment can be performed at a repair shop. Tires are round, elastic rubber products that roll on the ground. If the tire pressure is too low, it can lead to increased fuel consumption, heavier steering, damage and abnormal wear to the tire bead area, and reduced tire strength.

What counts as speeding when the speed limit is 100?

Speeding occurs as long as the speed exceeds 100 when the speed limit is 100. Definition of speeding: Speeding refers to a driver operating a vehicle at a speed that exceeds the legal or regulatory speed limit. According to Article 42 of the Road Traffic Safety Law of the People's Republic of China, motor vehicles driven on roads must not exceed the maximum speed indicated by speed limit signs. On road sections without speed limit signs, drivers should maintain a safe speed. Hazards of speeding: Speeding increases the difference in airflow velocity between the top and bottom of the vehicle body, reducing stability during driving; higher speeds mean stronger inertia for maintaining straight-line movement, leading to poorer directional control and significantly increased risks; speeding forces the driver's line of sight to focus farther ahead, making nearby objects appear more blurred.

How significant is the impact of a slightly dented oil pan?

The impact of a slightly dented oil pan is not significant. If the oil pan is slightly deformed but does not leak oil, it will not affect the lubrication performance. Oil Pan: It is the lower half of the crankcase, also known as the lower crankcase. Its function is to enclose the crankcase as the outer shell of the oil reservoir, preventing impurities from entering. It also collects and stores the lubricating oil flowing back from the friction surfaces of the diesel engine, dissipates some heat, and prevents the oxidation of the lubricating oil. Causes of Oil Pan Damage: When driving on the road, minor scrapes are inevitable, not only on the body but also on the chassis. On some rough and uneven roads, it is common for stones to scrape and damage the chassis, with the oil pan being the first to bear the impact. Therefore, the oil pan is prone to damage.

What is the displacement of the CFMoto 250SR?

The displacement of the CFMoto 250SR is 250cc. Displacement: A specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Generally, a larger displacement means the engine releases more energy (converting chemical energy of fuel into mechanical energy) per unit time, indicating better "power performance." Engine displacement is one of the most important structural parameters, more representative of engine size than bore and cylinder count. Many engine metrics are closely related to displacement. CFMoto 250SR: Equipped with the same engine as the CFMoto 250NK, a 250cc single-cylinder liquid-cooled engine with a maximum power of 20.5kw and maximum torque of 22 Nm. It accelerates from 0-100 km/h in 7.5 seconds, features LED headlights, a full-color LCD instrument panel, and optional ABS, among other features.
