What is the Principle of Ultrasonic Sensors?

Ultrasonic sensors primarily consist of two types of materials: piezoelectric crystals and nickel-iron-aluminum alloys. Piezoelectric crystal-based ultrasonic sensors are reversible transducers that can convert electrical energy into mechanical oscillations to generate ultrasonic waves. Conversely, when they receive ultrasonic waves, they can also convert them back into electrical energy. Below are some key aspects of ultrasonic waves: 1. Ultrasonic waves are mechanical vibrations with frequencies higher than 20 kHz. They are characterized by high frequency, short wavelength, minimal diffraction, and particularly strong directionality, allowing them to propagate directionally like rays. 2. Ultrasonic waves have strong penetration capabilities in liquids and solids, especially in opaque solids. When encountering impurities or interfaces, they produce significant reflections, forming echo signals. Additionally, they generate the Doppler effect when interacting with moving objects. 3. Ultrasonic sensors utilize sound wave media to perform non-contact, wear-free detection of objects. They can detect transparent or colored objects, metals or non-metals, as well as solids, liquids, and powdered materials. Their detection performance is virtually unaffected by any environmental conditions, including smoke, dust, or rainy weather.

What is the chassis code of the BMW 7 Series?

The chassis code of the BMW 7 Series is G70. The chassis refers to the four major components of a vehicle: the transmission system, running gear, steering system, and braking system. Its function is to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power to enable the car to move and ensure normal driving. The BMW 7 Series is a large luxury car equipped with four engines: a 2.0-liter turbocharged engine, a 3.0-liter turbocharged engine, a 4.4-liter twin-turbocharged engine, and a 6.6-liter twin-turbocharged engine. Among them, the 2.0-liter turbocharged engine has a maximum power of 195 kW, a maximum torque of 400 Nm, a maximum power speed of 5000 to 6500 rpm, and a maximum torque speed of 1550 to 4500 rpm. This engine is equipped with direct injection technology and uses an aluminum alloy cylinder head and block.

What Causes the P Gear to Get Stuck?

Automatic transmission P gear getting stuck usually occurs when the P gear is hastily engaged before the vehicle comes to a complete stop, leading to difficulty in moving the gear lever. Below are the relevant details: 1. Function of the P gear: The P gear is designed to lock the rotating parts of the car mechanically, preventing the vehicle from moving. When the car needs to stay in a fixed position for an extended period or before leaving the vehicle after parking, the hand brake should be engaged, and the gear lever should be pushed into the P position. This mechanically locks the wheels to prevent rolling. 2. Avoiding damage: The P gear should only be used when the vehicle is completely stopped; otherwise, the mechanical parts of the automatic transmission may be damaged. Additionally, automatic transmission vehicles are equipped with a neutral start switch, ensuring the engine can only be started in the P or N gear to prevent sudden forward movement if accidentally started in other gears.

Does Revving the Engine in Neutral Gear Harm the Car?

Revving the engine in neutral gear can cause the following damages to the car: 1. Revving in neutral subjects the engine's moving parts to significant inertial forces, affecting the engine's reliability and lifespan. 2. When the car is in neutral, the engine does not output power. Rapidly increasing the engine speed by revving causes sudden acceleration of moving parts such as pistons and connecting rods, generating substantial acceleration and subjecting them to significant alternating loads. Additionally, the sharp rise in engine speed during revving can lead to inadequate lubrication in friction areas, increasing the risk of cylinder scuffing and bearing failure. 3. Prolonged revving in neutral can result in severe incomplete combustion. If the unburned fuel-air mixture ignites outside the cylinder, it may cause the vehicle to catch fire. Incomplete combustion also promotes carbon buildup, which can clog the catalytic converter, leading to abnormal high temperatures. These high temperatures may cause wiring to catch fire, with potentially serious consequences.
