How Does a Manual Transmission in a Car Work?

What is the relationship between Volkswagen, Mercedes-Benz, and BMW?

Mercedes-Benz is one of the subsidiaries under the Volkswagen Group, while BMW is in a competitive relationship with both companies. Here is some extended information about BMW: 1. Full company name: Its full name is die Bayerischen Motorenwerke (Bavarian Motor Works). Over the past century, BMW has evolved from an aircraft engine manufacturer into an enterprise group that primarily focuses on premium cars and also produces world-renowned aircraft engines, off-road vehicles, and motorcycles. 2. Global rankings: On December 18, 2018, the '2018 World's 500 Most Influential Brands' list compiled by the World Brand Laboratory was announced, with BMW ranking 16th. In October 2019, Interbrand ranked BMW 11th in its Global Top 100 Brands list. On January 22, 2020, BMW was ranked 32nd on Fortune's 'World's Most Admired Companies' list.

What Does a Four-Cylinder Car Mean?

Four-cylinder car refers to a car engine with 4 cylinders. Here is some relevant information: 1. Cylinders: An engine has several cylinders, and the sum of the working volumes of all cylinders is called the engine displacement, usually expressed in liters (L). Common cylinder numbers for car engines are 3, 4, 5, 6, 8, 10, and 12. Engines with a displacement below 1 liter typically use three cylinders, those between 1-2.5 liters usually have four cylinders, around 3 liters generally have six cylinders, around 4 liters have eight cylinders, and those above 5.5 liters use twelve cylinders. 2. Influencing factors: Generally, with the same cylinder diameter, more cylinders mean greater displacement and higher power; with the same displacement, more cylinders with smaller diameters can increase speed, thereby achieving higher power output.

How High Does Water Need to Reach to Affect the Engine?

If a car is submerged above the tire level, it can cause problems. The biggest concern when a vehicle is submerged in water is the impact on the engine and electrical systems. Water entering the engine's air intake can directly affect the engine, and the electrical systems inside the car are also highly sensitive to water. Therefore, water should never exceed the tire level, as it can lead to water entering the cabin or the engine. The following components must be replaced if the vehicle is submerged: 1. Engine: If the vehicle does not stall or has not been started after being submerged, the engine oil, oil filter, air filter, and seals during the drainage process of engine components need to be replaced. If the engine stalls or is restarted, in addition to the above components, the engine connecting rods may need to be replaced depending on the situation, requiring an engine overhaul. 2. Transmission: Transmission fluid and transmission filter. 3. All vehicle fluids: If the vehicle is severely submerged, all fluids, including engine oil, coolant, power steering fluid, and brake fluid, must be replaced. 4. Bearing components: If the water level reaches the engine hood and the submersion time is prolonged, it is recommended to replace all bearing components to avoid rust, noise, and damage later on, such as the generator, air conditioning compressor, and wheel bearings.

Can an Electric Vehicle Be Used Normally After Drying Out from Water Ingress?

Under normal circumstances, an electric vehicle can be used normally after drying out from water ingress, as electric vehicles generally have a certain level of waterproofing. However, the severity of the water ingress must be considered. If the water ingress is relatively severe, components such as the controller, circuit board, and motor should be cleaned promptly to prevent short circuits. To avoid electric leakage or electric shock accidents after water ingress or wading, the power supply can be turned off via the control panel. Solution for motor water ingress: The motor is one of the core technologies of an electric vehicle and the area responsible for generating propulsion. If water enters the motor, it can immediately render the vehicle inoperable. If the water depth is not too deep and the duration is short, the motor should be disassembled and tilted overnight, with the tilt direction toward the motor shaft (i.e., the wiring side). Since the motor shaft is hollow, tilting it will allow accumulated water to drain from the shaft. If the water ingress is severe, the motor's securing screws should be loosened, and the motor should be placed in sunlight to dry. Drying time for water ingress in electric vehicles: Generally, if the internal circuits are not affected by water, the vehicle can often be reused the next day. If the water ingress is severe, it is best to leave the vehicle untouched for 24 days.

Are there any requirements for the photo on the driver's license?

The photo on the driver's license must be a straight-edged, front-facing, bareheaded color ID photo of the individual's upper body. For those with long hair, both ears should be visible, the background should be white, and the portrait should be clear and natural. Here is some relevant information about the driver's license: 1. Introduction: The full name of the driver's license is the Motor Vehicle Driver's License, also known as the "driver's license," which is a certificate required by law for motor vehicle drivers. 2. License renewal period: If a motor vehicle driver does not accumulate 12 penalty points in any scoring period during the six-year validity period of the driver's license, they can renew it for a ten-year validity period. If they do not accumulate 12 penalty points in any scoring period during the ten-year validity period, they can renew it for a long-term valid driver's license.

How deep does water need to be for the engine to take in water?

If water reaches half the height of the car tires or the level of the exhaust pipe, it is highly likely that the engine will take in water. Here are the relevant details: 1. Air intake: If rainwater enters the engine through the car's air intake, it can damage the engine (potentially causing hydro-lock). Therefore, how deep the water needs to be to affect the car depends on different vehicle models, primarily determined by the position of the air intake. 2. Distance from the ground: For ordinary sedans, the exhaust pipe is typically 20 to 30 centimeters from the ground, while for SUV models, it is 30-40 centimeters. However, there are exceptions, such as vehicles equipped with a snorkel, which significantly increases the car's wading depth. A snorkel, also known as a "high-position air intake pipe" or "wading kit," is essentially an extended air intake pipe.
