Why is the car engine buzzing?

The buzzing noise from a car engine may be caused by worn or loose wheel bearings or uneven tire wear. Below is an introduction to engines: 1. Introduction: An engine is a machine that converts non-mechanical energy into mechanical energy. 2. Classification: Engines include internal combustion engines (reciprocating piston engines), external combustion engines (such as Stirling engines, steam engines, etc.), jet engines, electric motors, etc. 3. External combustion engine: An external combustion engine refers to an engine where the fuel is burned outside the engine. 4. Internal combustion engine: An internal combustion engine, also known as a reciprocating piston engine, differs from an external combustion engine in that the fuel is burned inside the engine. There are many types of internal combustion engines, with gasoline engines and diesel engines being the most common examples.

Why can't the car key turn and the engine won't start?

The reason why the car key is inserted but cannot be turned and the engine won't start is that the steering wheel lock is jamming the key. Here are other possible reasons and solutions: 1. Solution when the steering wheel is locked and the car key cannot turn: Hold the steering wheel with your left hand and gently shake it while simultaneously turning the key left and right with your right hand to unlock it. 2. The steering wheel lock is a simple anti-theft feature: After the car is turned off, rotate the steering wheel from the straight position to one side (usually left) by a certain angle, and the steering wheel will "click" and lock into place. 3. When the steering wheel is locked, it won't move and the key cannot turn: Solution: Hold the steering wheel with your left hand and gently shake it while simultaneously wiggling the key with your right hand to unlock it.

How to Repair Car Paint?

If the paint is scratched and you don't want to go for professional repair, you can purchase touch-up pens and mini spray cans for treatment. Below is some information about car paint: 1. Paint Distribution: The exterior of a car consists of 13 painted surfaces: the front and rear bumpers, the left and right front fenders, the two left doors, the two right doors, the left and right rear fenders, the front hood, the rear trunk lid, and the roof. 2. Paint Material: Car paint generally has four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives. The film-forming substance is the main component of the paint, responsible for keeping the pigment bright, making it durable and able to adhere to the surface, and is the substance that determines the type of paint.

What happens when a car's exhaust pipe is blocked?

When a car's engine exhaust system becomes blocked, corresponding fault symptoms will appear depending on the severity of the blockage. Here is an introduction to car exhaust pipe knowledge: 1. Definition: The car exhaust bellows, also known as the car exhaust flexible hose, is installed in the exhaust pipe between the engine exhaust manifold and the muffler. It creates a flexible connection for the entire exhaust system, serving to reduce vibration and noise, facilitate installation, and extend the lifespan of the exhaust muffler system. 2. Material selection: Ferritic stainless steel has a small thermal expansion coefficient and high thermal conductivity. It exhibits good high-temperature oxidation resistance under repeated heating and cooling conditions, along with excellent pitting corrosion resistance.

Where is the problem when a car smells like rotten eggs?

The rotten egg smell inside the car is mainly caused by hydrogen sulfide in the exhaust. Below is some information about automatic detection of unqualified exhaust on highways: 1. Cylinder wear: There is a large amount of carbon deposits and tar, and the three-way catalytic converter and oxygen sensor have failed. Check the air filter, spark plugs, intake air temperature sensor, intake pipe pressure sensor, and add dual-core anti-wear repair agent and high-efficiency cleaner. If ineffective, use a three-way catalytic converter cleaner to clean the three-way catalytic converter. It may be due to insufficient oxygen supply in the intake system, cylinder wear, or carbon deposits in the cylinder. 2. Solution: The three-way catalyst and front oxygen sensor, incomplete combustion of the engine's air-fuel mixture will generate a large amount of carbon deposits. Therefore, cleaning the three-way catalytic converter and oxygen sensor will solve many problems of unqualified vehicle exhaust. If the fuel quality is problematic, the sulfur, lead, and phosphorus contained in the fuel can cause three-way catalyst poisoning, leading to the failure of the three-way catalytic converter.
