What is the principle of crankcase ventilation?

The principle of crankcase ventilation is: When the engine piston moves upward, the gas pressure inside the crankcase is negative, and the ventilation pipe draws air from the outside. When the piston moves from the top dead center downward, the pressure inside the crankbox changes from negative to positive, and the crankcase ventilation pipe exhausts gas to the outside. The following are the functions of the engine crankcase ventilation system: 1. Prevent lubricating oil from deteriorating and reduce corrosion of friction components. During engine operation, some combustible mixture and exhaust gas leak into the crankcase. The leaked gasoline vapor condenses, thinning the oil and degrading its performance, thereby reducing lubrication effectiveness. If the exhaust gas contains water vapor and sulfur gases, sulfuric acid can form, causing corrosion to the components. 2. Reduce pressure and temperature to prevent overheating. The gas leaking into the crankcase increases the pressure and temperature inside, causing oil leakage and deterioration from seals and gaskets. Ventilation helps cool the oil, reduce pressure, and prevent leakage. 3. Reduce atmospheric pollution and recover combustible gases, which improves fuel economy and reduces emission pollution.

Can a spare key start the car?

Every car comes with two keys, a primary key and a spare key. Although there is a distinction between primary and spare, both keys have the same functionality and can be used to start the vehicle and lock it. Below is additional information about car keys: 1. A remote key allows you to unlock and lock the car from a distance without inserting the key into the lock. Its biggest advantage is that, regardless of whether it's day or night, you don't need to locate the keyhole and can conveniently unlock or lock the car from afar. 2. The working principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator (either a motor or an electromagnetic coil) performs the locking or unlocking action. This system mainly consists of two parts: a transmitter and a receiver.

Where is the battery located in the Mercedes-Benz C200L?

You can locate the battery of a Mercedes-Benz vehicle using the following methods. 1. First, pull the engine lock lever located at the lower left side of the vehicle's cockpit to unlock the engine hood of the Mercedes-Benz C200L. 2. Then, pull the lever on the engine hood to open it. 3. After that, you can use the hydraulic rod to prop up the engine hood. Once propped up, you can see the layout of the engine compartment. 4. Next, you can find the vehicle's battery at the indicated position in the engine compartment. More details about the battery are as follows: 1. The commonly used batteries in vehicles are lead-acid batteries. Maintenance-free batteries are usually equipped with a charge indicator (also known as a charging indicator), which can indicate the battery's charge level or charging status. The indicator displays colors such as green, black, colorless, or light yellow. 2. When the ambient temperature increases by 1°C, the battery's capacity will correspondingly increase by 0.8%; conversely, when the ambient temperature decreases by 1°C, the battery's capacity will correspondingly decrease by 0.8%. 3. When the temperature drops to -10°C, the battery's capacity is only 72% of its normal value; when the temperature drops to -20°C, the battery's capacity is only 64% of its normal value. Additionally, car batteries are shallow-cycle lead-acid batteries, and over-discharging can cause significant damage to the battery. You can find the vehicle's battery at the indicated position in the engine compartment.
