Why Does the Engine Noise Increase After an Oil Change?

There are several reasons why engine noise may increase after an oil change: 1. Overfilling of engine oil: When there is too much oil in the engine, it creates unnecessary resistance to the rotation of the crankshaft, affecting power output, increasing fuel consumption, and consequently raising noise levels. 2. Unsuitable oil viscosity: If the oil viscosity is too high, it creates greater rotational resistance when the engine is cold, leading to insufficient lubrication and increased noise during cold starts. 3. Severe engine carbon buildup: Over time, engine oil becomes thinner, and carbon deposits accumulate. When new oil is first added, the engine may not immediately adapt to the oil's viscosity, resulting in increased engine noise.

Is it necessary to install an engine guard plate on a car?

It is necessary to install an engine guard plate on a car, and its functions are: 1. It can protect engine components and various pipelines, preventing damage caused by contact and friction with the ground under harsh working conditions; 2. It improves the smooth flow of air under the car, reduces wind resistance and wind noise, thereby improving fuel economy and overall vibration and noise performance. The engine guard plate is an engine protection device designed specifically for various car models, preventing mud from covering the engine. Through a series of designs, it extends the service life of the engine and avoids car breakdowns due to external factors damaging the engine during travel.

What does the TC sign on the car mean?

TC sign on the car refers to the Traction Control System, which relies on ABS anti-lock braking system electronic sensors. When it detects that the speed of the driven wheel is lower than that of the driving wheel, it sends a feedback signal to the car system. The car system will then adjust the ignition timing, reduce the throttle opening, decrease the throttle, downshift or brake the wheels accordingly to prevent wheel slippage. The Traction Control System uses the steering wheel angle sensor to understand the driver's steering intention and utilizes the left and right wheel speed sensors to detect the speed difference between the wheels, thereby determining whether the car's steering degree matches the driver's steering intention.

Why does the car make noise when driving?

The reasons for the car making noise while driving are as follows: 1. If the car itself has no faults, it can generally be determined that there are large foreign objects stuck in the tire treads. For example, large stones, big-headed self-tapping screws, olive pits, etc. Solution: Remove them and check if there are any abnormalities with the tire. If there are no issues, no further action is needed. If the tire is damaged, it is best to replace it. 2. The car itself has a fault. In this case, the causes can be quite varied, but usually, the dashboard will light up a fault indicator. Solution: Go to a 4S shop or a professional auto repair shop and have professionals inspect it to determine the problem and then fix it accordingly.

How much t is equivalent to a 1.6L engine?

Engine 1.6L is equivalent to 1.2t, which means the power of a 1.6L naturally aspirated engine is comparable to that of a 1.2L turbocharged engine. Of course, there may be some differences depending on the power tuning of different car manufacturers for their models. Since a turbocharged engine compresses air through a turbine before delivering it to the engine's cylinders, making combustion more efficient, a turbocharged engine of the same displacement will have more power than a naturally aspirated engine. An engine is a machine that can convert other forms of energy into mechanical energy, including types such as internal combustion engines, external combustion engines, and electric motors.

What materials are needed for car registration?

The main documents required for motor vehicle registration are as follows: 1. ID card, vehicle certificate, purchase invoice, and compulsory insurance policy. 2. In addition, for cities with license plate restrictions such as Beijing, Shanghai, Guangzhou, and Shenzhen, users also need to provide a car purchase qualification certificate. Extended content: The procedures for vehicle registration mainly include: 1. Paying the vehicle purchase tax and obtaining the tax certificate. 2. Preparing various documents, registering at the vehicle management office, and inspecting the vehicle. 3. Selecting the vehicle license plate number. After the vehicle inspection, you can go to the vehicle management office hall to choose a number. 4. Paying the fee and waiting to receive the license plate. After selecting the number, pay the fee and wait to receive the license plate, which usually takes three to five working days.
