What are the functions of engine cleaners and protectants?

Cleaners and protectants serve different purposes: one removes dirt and contaminants for expulsion, while the other forms a protective film. However, both functions can be achieved by engine oil alone. One of the primary roles of engine oil is to clean the internal components of the engine, thereby reducing wear on various parts. Protecting the Engine: Engine cleaners primarily target sludge removal in the crankcase, whereas engine protectants enhance the oil's anti-wear properties and inhibit sludge formation. Consequently, manufacturers often bundle these two products for sale. The process involves adding the cleaner to old oil before an oil change for cleaning, draining the old oil, refilling with fresh oil, and finally adding the protectant to establish engine protection. Base Oils: Base oils are categorized into three types: mineral oil, semi-synthetic oil, and full synthetic oil.

What Causes Abnormal Engine Speed Signal?

Abnormal engine speed signal can be caused by the following reasons: Dirty Idle Speed Control Valve: This phenomenon is relatively common in electronic fuel injection vehicles, usually caused by a dirty (or damaged) idle speed control valve. When this occurs, it is recommended to clean the engine's idle speed control valve and carefully check whether the throttle valve is functioning properly or if there is any sticking due to excessive dirt. Incorrect Temperature Sensor Signal: An incorrect coolant temperature sensor signal can lead to an increase in idle speed. Due to intermittent faults in the coolant temperature sensor, it may transmit a coolant temperature far below the actual temperature, causing the control unit to mistakenly believe the engine is operating at a low temperature. This results in excessive air intake and fuel injection, leading to an abnormal increase in idle speed, which can exceed 2000r/min.

What Causes Engine Shaking and Exhaust Pipe Abnormal Noise?

Engine shaking and exhaust pipe abnormal noise can be attributed to the following reasons: Engine Misfire: Engine misfire primarily refers to one or more cylinders in the engine not functioning properly. Common symptoms include: intermittent exhaust gas flow from the vehicle, severe shaking of the exhaust pipe, and clear audible sounds from the engine such as "popping" or "thumping" noises. This phenomenon is often closely related to ignition coil failure. Overly Rich Air-Fuel Mixture: When the engine's air-fuel mixture is too rich, the symptoms include: difficulty starting the engine; poor acceleration after starting, uneven engine operation; black smoke from the exhaust pipe accompanied by popping sounds from the engine, sometimes even backfiring; decreased engine power and increased fuel consumption. These issues are mostly related to carbon buildup, clogged filters, etc.

Which car has the hazard light switch in the middle of the air vent?

There are many models, such as the Volkswagen Lamando, New Santana, Lavida, Gran Lavida, Cross Lavida, New Passat, Tiguan, Touran, New Jetta, Bora, Golf, Sagitar, etc., all feature this design. Introduction to the hazard light switch: The hazard warning flasher, commonly referred to as the 'double flash', is a signal light used to alert other vehicles and pedestrians that the vehicle is experiencing a special situation. When to turn it on: The hazard lights should be activated in the following situations: when the vehicle breaks down, when there is a breakdown on the highway, when towing a faulty vehicle, when transporting critically ill patients, when encountering an emergency while driving, when temporarily parked on the road, when involved in a traffic accident, when reversing or making a U-turn, when a driving school car is practicing, and when performing special tasks.

Is it serious if a car tire is punctured very deeply but not leaking air?

A car tire that is punctured very deeply but not leaking air should be checked as soon as possible to avoid unnecessary trouble. Tire Cold Patching: Cold patching involves removing the damaged tire, locating the puncture, cleaning the affected area, and applying a specialized tire repair patch to seal the leak. This method is similar to patching a bicycle tire but requires specialized tire removal equipment and repair patches. The advantage is that it can repair larger punctures, but the downside is that it is less durable. Tire Hot Patching: Hot patching, commonly known as vulcanizing, is a more thorough tire repair method. It also involves removing the tire and applying a specialized uncured rubber patch to the puncture. A heating machine is then used to bond the patch to the tire until it fully adheres. The benefit of hot patching is its durability, as there is little concern about the puncture leaking again. However, the downside is that it requires higher technical skill and takes more time.

Is the ticking sound when starting the new A6 the ABS working sound?

When starting the new A6, there is a ticking sound, which is the working sound of the ABS. It is the sound of the automatic parking function releasing the brake. Introduction to car ABS: Car ABS is an anti-lock braking system. The working principle of the braking system is to use the mutual friction between the non-rotating elements connected to the body (or frame) and the rotating elements connected to the wheels (or drive shaft) to prevent the rotation or tendency of rotation of the wheels. The role of ABS: ABS automatically controls the braking force of the brake during car braking, preventing the wheels from locking up and keeping them in a state of rolling and sliding, ensuring that the adhesion between the wheels and the ground is at its maximum. During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that begins to lock up, and keeps the braking force unchanged.
