Here are the types of automotive sensors: 1. Throttle Position Sensor; The throttle position sensor is installed on the throttle to detect the throttle opening. 2. Intake Pressure Sensor; The intake pressure sensor can measure the absolute pressure in the intake manifold based on the engine's load condition and convert it into an electrical signal, which is sent to the computer along with the speed signal as the basis for determining the basic fuel injection amount. 3. Crankshaft Position Sensor; The crankshaft angle sensor is the most important sensor in a computer-controlled ignition system. Its function is to detect top dead center signals, crankshaft angle signals, and engine speed signals, and input them into the computer, enabling the computer to issue the optimal ignition timing command according to the cylinder's firing order. 4. Air Flow Sensor; The air flow sensor converts the inhaled air into an electrical signal and sends it to the electronic control unit (ECU) as one of the basic signals for determining fuel injection. 5. Knock Sensor; The knock sensor is installed on the engine block to continuously monitor the engine's knock condition. 6. Temperature Sensor; 7. Engine Speed Sensor; 8. Vehicle Speed Sensor (SPD), etc.

What is the purpose of the shark fin on BMW roofs?

BMW's shark fin serves the following purposes: 1. Preventing rear-end collisions: The anti-rear-end function is mainly evident during night driving. Most of the time, the leading vehicle uses brake lights to alert the following vehicle to slow down. Since most shark fins are equipped with LED light-emitting devices, they will continuously flash when the driver applies the brakes. This flashing light source has a significant warning effect on the human eye, effectively reminding the following vehicle to slow down and thus preventing rear-end accidents. 2. Reducing air resistance and turbulence: Cars encounter air resistance while driving, and the faster the speed, the greater the resistance. Air resistance can affect the car's speed and increase fuel consumption to some extent. After installing the shark fin on the roof, the airflow can be disrupted. Conventional antennas not only reduce resistance but also create vortices. After replacing them with shark fins, air resistance and noise are reduced. To a certain extent, it can also lower fuel consumption by 3%. 3. Absorbing static electricity: The small tail standing on the roof is actually a static discharger. During winter or dry autumn, static electricity can easily accumulate on the car body. If static electricity is not handled, it may cause trouble for the owner and, more dangerously, pose a threat at gas stations. BMW's shark fin can absorb static electricity to solve such problems.

How Long is a Typical Sedan?

Generally, the length of a typical sedan ranges between 3800mm and 4300mm, the width between 1600mm and 1800mm, and the height between 1400mm and 1600mm. A small car is defined as one with a total mass not exceeding 4.5 tons, seating capacity (including the driver) not exceeding 9 people, or a vehicle length under 6 meters. Sedans can be categorized into the following lengths: Microcars: Typically refer to models with a wheelbase under 2400mm, such as the Chery QQ3, Changan Benben, and Geely Panda, which have wheelbases around 2340mm. Even smaller is the SMART FORTWO, with a wheelbase of only 1867mm. Subcompact Cars: Usually refer to models with a wheelbase between 2400mm and 2550mm, such as the Honda Fit, Toyota Vios, and Ford Fiesta. Compact Cars: Typically refer to models with a wheelbase between 2550mm and 2700mm. This category represents the mainstream of family sedans, including models like the Volkswagen Sagitar, Toyota Corolla, Ford Focus, and Honda Civic.

Is Tire Bulging Covered Under the Three Guarantees Policy?

Whether tire bulging is covered under the three guarantees policy depends on the specific circumstances. Generally, new car tires come with a one-year warranty. If bulging or other issues occur within the warranty period and are confirmed by national authoritative departments to be caused by manufacturing defects, the manufacturer will provide compensation or replacement according to the three guarantees law. Tire Three Guarantees Policy: If quality issues are discovered before actual use after purchasing the tire, a new tire can be exchanged. For appearance-related quality issues, both parties can negotiate a solution. If quality issues are found during use, the compensation standard is calculated based on the remaining tread depth: • If the remaining tread depth is over 70%, a new tire will be replaced free of charge. • If the remaining tread depth is between 60%-69%, the replacement cost is 30% of the factory price. • If the remaining tread depth is between 50%-59%, the replacement cost is 40% of the factory price. • If the remaining tread depth is between 40%-49%, the replacement cost is 50% of the factory price. • If the remaining tread depth is between 30%-39%, the replacement cost is 75% of the factory price.

Can I Check My Driving Test Scores After Passing?

After obtaining your driver's license, you cannot check your scores online. However, the records are kept by the Vehicle Management Office, which contains transcripts for each subject. If you need to check, you can visit the Vehicle Management Office. Additional information: Driving test passing standards: 1. Traffic regulations and related knowledge (Subject 1): Written test, full score of 100, 90 or above is passing (including 90). 2. Field driving (Subject 2): On-site, actual vehicle. Only pass or fail. Nine compulsory test items (all without poles), including reversing into a garage, narrow road U-turn, parallel parking, hill start, right-angle turn, curve driving, emergency braking, tunnel, and toll booth card collection. All nine items must be passed to pass Subject 2. 3. Road driving (Subject 3): Highway or simulated site, actual vehicle. The test is fully monitored by electronic eyes + traffic police examination, making the road test more fair. Since January 1, 2013, with the implementation of the new traffic regulations, the test has added light usage, left and right turns, and pedestrian crossing items. After the road test, there is an additional theoretical test on safe and civilized driving knowledge, which differs from Subject 1 by adding image analysis and judgment. The test has 50 questions, each worth 2 points. Full score is 100, 90 or above is passing.
