Replacing the engine connecting rod generally has little impact, but improper handling afterward may cause engine vibration. Impact of Replacing the Engine Connecting Rod: No impact. The motion pair between the connecting rod and the crankshaft is a friction pair. The connecting rod and the crankshaft are matched with bearing shells, lubricated by engine oil in between, with a fit clearance of only 0.03-0.05mm. Most crankshafts are made of ductile iron, with different grades resulting in varying quenching hardness, mostly between HB130-240. Characteristics of Automotive Engines: Common gasoline and diesel engines are both reciprocating piston-type internal combustion engines, capable of converting the chemical energy of fuel into the mechanical energy of piston movement and outputting power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, excellent thermal efficiency, and better economic and emission performance than gasoline engines.

Where is the engine number located on the Volkswagen Teramont?

The engine number of the Volkswagen Teramont is located on the left side of the engine. Here is some relevant information: 1. It is necessary to distinguish between the engine code and the engine model. The engine code is like the ID card of the engine, while the engine model is like the name of the engine. 2. Taking the Volkswagen Teramont as an example, all 2.0T versions of the Teramont produced in the factory use the EA888 engine, but each EA888 engine has a different engine code. The engine model is used to distinguish between different engines, while the engine code is used to distinguish between the same type of engine. From the engine code, you can find out the production factory, date, and parameters of the engine. 3. Different brands of engines have different ways of expressing their codes. The purpose of using the engine code is not only to facilitate the search for parts during maintenance but also to avoid the situation of engine substitution.

Why Does the Car Remote Key Suddenly Stop Working?

There are several reasons why a car remote key may stop working: 1. The battery is dead or has poor contact, the time control module in the remote key is malfunctioning, or the car's remote transmitter antenna is aging. 2. The front windshield has been fitted with explosion-proof solar film, which can partially block the remote signal. 3. During use, avoid exposing smart remote keys to strong magnetic fields, such as high-voltage power lines, transmission towers, or other areas with strong magnetic signals. Smart keys use low-intensity radio waves and cannot function properly under magnetic interference.

Where is the car antifreeze located?

Car antifreeze is located in the car's radiator, and its specific position can be seen by opening the front engine hood. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block or head when the car is parked in cold winter. The following points should be noted when purchasing antifreeze: 1. Choose the freezing point of the antifreeze according to the environmental temperature conditions. The freezing point of antifreeze is one of the most important indicators of antifreeze and a key condition for its antifreeze function. The freezing point of the antifreeze should be selected based on the local winter minimum temperature, typically 10℃ to 15℃ below the local lowest temperature. For example, if the local minimum temperature is -30℃, the freezing point of the antifreeze should be below -45℃. 2. Choose antifreeze according to the different requirements of the vehicle. Imported vehicles, domestically produced vehicles, and high-end vehicles should use permanent antifreeze (2-3 years), while ordinary vehicles can use direct-use antifreeze, and softened water can be used in summer. 3. Choose antifreeze with rust-proof, anti-corrosion, and descaling capabilities. The most important function of antifreeze is to prevent rust. It is advisable to choose well-known brand products that contain corrosion inhibitors, rust inhibitors, scale inhibitors, and cleaning agents to ensure product quality. 4. Choose antifreeze that is compatible with rubber sealing conduits. The antifreeze should not have side effects such as swelling or erosion on rubber sealing conduits.
