What Causes Severe Car Vibration?

Car vibration can be caused by the following reasons: 1. Excessive carbon deposits. 2. Fuel supply system failure. 3. Aging engine mounts. 4. Misfiring or cylinder failure. Detailed explanations are as follows: 1. Excessive carbon deposits: Severe carbon buildup in the engine cylinders can lead to clogged spark plugs or valves, directly causing the car to vibrate at idle. If the vehicle's acceleration performance has significantly declined and the vibration persists, an engine cylinder cleaning may be necessary. 2. Fuel supply system failure: Unstable fuel pressure can cause fluctuations in the air-fuel mixture concentration, resulting not only in vibration but also unstable idling. First, consider replacing the fuel filter, as prolonged use may clog it. Then, check the fuel pressure bypassing the fuel filter; if abnormal, the issue may lie with the fuel pump. 3. Aging engine mounts: This is a very common cause of vibration. If the engine vibration worsens over time without a corresponding loss of power, the engine mounts may be the culprit. 4. Misfiring or cylinder failure: This is the most common cause of engine vibration, typically due to issues with the ignition coil or spark plugs. If the ignition coil malfunctions or the spark plug fails to fire for any reason, the car will experience vibration.

What does 'vehicle online inspection' mean?

"Vehicle online inspection": refers to the online testing process, which is one of the steps in the annual vehicle inspection. Only vehicles that pass this inspection can officially complete the annual review, obtain the annual inspection mark, and be allowed to continue driving on the road. The online inspection mainly involves testing the brakes, headlights (high beam), chassis, and other components, taking approximately 5-10 minutes. Relevant information about the annual vehicle inspection is as follows: 1. Introduction: Vehicle annual inspection (Vehicles-inspection), also known as motor vehicle inspection. The inspection items and scope vary depending on the usage nature of the motor vehicle. 2. Inspection items: According to the definition in RB/T218-2017 "Requirements for Inspection and Testing Institutions Qualification Accreditation Capability Evaluation - Motor Vehicle Inspection Institutions," motor vehicle inspection includes three categories: motor vehicle safety technical inspection, motor vehicle emission inspection, and comprehensive performance inspection of automobiles.

Can antifreeze of different colors be mixed?

Antifreeze of different colors cannot be mixed. Different colors indicate different compositions, and mixing antifreeze with varying components can lead to chemical reactions, rendering the antifreeze ineffective or even causing it to solidify. Even if the antifreeze is the same color, different brands may use different stabilizers, and mixing them can reduce cooling and cleaning performance. Therefore, it is best not to mix them. Ideally, use antifreeze of the same brand and color. If antifreeze is accidentally mixed, the antifreeze in the radiator must be completely drained, flushed with purified water, and then refilled. Antifreeze typically comes in colors such as green, blue, pink, and some may even have fluorescent effects. Generally, ethylene glycol-based antifreeze is green, propylene glycol-based is blue, and glycerol-based is pink. Manufacturers dye antifreeze different colors for the following purposes: Prevent mixing: To avoid confusion with other liquids and prevent accidental ingestion, many manufacturers add different color formulations for distinction. Easier leak detection: When the engine leaks, the colored antifreeze makes it easier to identify during inspection and repair. Safety considerations: These chemical components in the engine are toxic, so fluids like windshield washer fluid and antifreeze are often dyed to prevent accidental ingestion.

How to Quickly Remove Formaldehyde from a Newly Purchased Car?

Methods to quickly remove formaldehyde from a newly purchased car are as follows: 1. Remove plastic wraps promptly: After buying a new car, do not delay removing the interior plastic packaging to maintain the car's freshness. Remove it as soon as possible to allow harmful gases to release quickly. 2. Ventilate by opening windows: To accelerate the dissipation of harmful gases, an effective method is ventilation. Before starting the car each time, open the windows to let air circulate, then drive. Alternatively, when parking, leave a small gap in the windows to maintain ventilation inside the car, which can effectively reduce the harm of formaldehyde.

What is the role of car ABS?

ABS system functions: Maximize the effectiveness of the brakes, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering control. Avoid severe friction between tires and the ground, reducing tire wear. ABS classification: ABS is mainly classified by channels. In ABS systems, the brake pipelines that can independently adjust brake pressure are called control channels. ABS control channels are divided into four-channel, three-channel, two-channel, and one-channel types. One-channel ABS: Also called single-channel ABS, it has one brake pressure regulator in the rear wheel brake main pipe, with one wheel speed sensor installed on the rear axle differential (some have one on each rear wheel). Two-channel ABS: This type of ABS struggles to balance directional stability, steering control, and braking effectiveness, and is rarely used today. Three-channel ABS: Independently controls the two front wheels, while the two rear wheels are controlled together based on the low-select principle (i.e., both wheels are controlled by one channel to ensure the wheel with less adhesion does not lock), also called hybrid control. Four-channel ABS: Has four wheel speed sensors, with one brake pressure regulator in each pipeline leading to the four wheel brake cylinders, enabling independent control and forming a four-channel control configuration.

How often should the transmission fluid be changed in a Reiz?

Reiz requires transmission fluid change every 40,000 kilometers or every two years. The primary function of transmission fluid is to maintain the cleanliness of the gear system, lubricate the transmission components, and extend their lifespan. There are two methods for changing the transmission fluid in a car: gravity drain and machine flush. The Reiz is a mid-size car under FAW Toyota, offering two powertrain configurations equipped with 2.5L V6 and 3.0L V6 naturally aspirated engines respectively. With its low and robust hood design combined with front and rear bumper styling, the Reiz achieves a low center of gravity vehicle structure, further emphasizing its distinctive exterior design philosophy.
