What is the Principle of Ultrasonic Sensors?

Ultrasonic sensors operate by converting ultrasonic signals into energy signals. Ultrasonic waves possess characteristics such as high frequency, short wavelength, minimal diffraction, and particularly strong directionality, enabling them to propagate directionally like rays. Ultrasonic waves exhibit significant penetration capabilities in liquids and solids, especially in opaque solids. When encountering impurities or interfaces, ultrasonic waves produce notable reflections, forming echo signals. Additionally, they generate the Doppler effect when interacting with moving objects. Ultrasonic sensors utilize sound wave media to perform non-contact, wear-free detection on objects. These sensors can detect transparent or colored objects, metallic or non-metallic materials, as well as solids, liquids, and powdered substances. Their detection performance remains unaffected by any environmental conditions, including smoky or rainy environments.

What Causes Engine Piston-to-Valve Interference?

Causes of engine piston-to-valve interference: 1. Hard objects falling into the combustion chamber; 2. Broken intake/exhaust valve springs causing valves to drop into cylinders; 3. Replacement pistons with incorrect geometric dimensions during overhaul; 4. Excessive thickness of replacement connecting rod bearings or gaskets during overhaul; 5. Damage to cylinder block surface caused by frequent cylinder head gasket failures. Repair methods for piston-to-valve interference: 1. For minor cases, only piston and valve replacement is needed; 2. For severe cases causing crankshaft journal bending, replacement of crankshaft, connecting rods, and bearing shells is required; 3. For extreme cases where cylinder walls are penetrated, replacement of cylinder liners, intake/exhaust valves, valve seats, valve stem seals, valve guides, valve oil seals, and camshaft is necessary.

What are the differences between Subject 1 and Subject 4 exams?

The main differences between Subject 1 and Subject 4 exams include: the number of questions, question types, content distribution, and exam focus. These are based on the "Regulations on the Application and Use of Motor Vehicle Driving Licenses". Number of questions: The most obvious difference between Subject 1 and Subject 4 is the number of questions. Subject 1 has 100 questions, while Subject 4 only has 50 questions. In Subject 1, the exam will automatically submit if more than 10 questions are answered incorrectly, whereas in Subject 4, the exam will automatically submit if more than 6 questions are answered incorrectly. Question types: Subject 1 consists of 100 questions, each worth 1 point, with a total exam time of 45 minutes. The question types are true/false and single-choice questions, with a full score of 100. Subject 4 consists of 50 questions, each worth 2 points, with a total exam time of 45 minutes. The questions are mainly in the form of case studies, images, animations, etc., and the question types include true/false, single-choice, and multiple-choice questions, with a full score of 100. Exam focus: Subject 1 primarily tests basic knowledge of road driving, while Subject 4 focuses on safe and civilized driving knowledge. It can be understood this way: Subject 1 tests how to drive, while Subject 4 tests how to drive safely. Although the difference is just two words ("safe"), the focus is entirely different. Content distribution: Subject 1 exam content consists of: 20% on driving license and motor vehicle regulations, 25% on road traffic conditions and regulations, 25% on road traffic safety violations and penalties, 10% on road traffic accident handling regulations, 10% on basic motor vehicle knowledge, and 10% on local regulations. Subject 4 exam content consists of: 20% on safe driving knowledge, 18% on civilized driving knowledge, 8% on the comprehensive application of road traffic signals in traffic scenarios, 16% on safe driving knowledge under adverse weather and complex road conditions, 12% on emergency avoidance knowledge, 6% on typical accident case analysis, 10% on traffic accident rescue and common hazardous chemical handling knowledge, and 10% on local test questions. There is no limit to the number of attempts for Subject 1 and Subject 4 exams. If you fail, you can reschedule the exam. Each scheduled exam has two attempts. If you fail both attempts, you can only retake the exam until you pass. Both Subject 1 and Subject 4 are theoretical exams and are part of the motor vehicle driving license assessment. There are a total of 3 subjects in the driving test: Subject 1, Subject 2, and Subject 3. Subject 1 refers to the road traffic safety laws, regulations, and related knowledge exam. Subject 2 refers to the field driving skills exam. Subject 3 is divided into two parts: road driving skills and safe and civilized driving knowledge exam. The safe and civilized driving knowledge exam is conducted after Subject 3, so it is commonly referred to as Subject 4. However, in the official terminology (i.e., the Ministry of Public Security Order No. 123), there is no such term as Subject 4.

What Maintenance is Required for a Car at 25,000 Kilometers?

The maintenance items at 25,000 kilometers include changing the engine oil and transmission fluid, replacing the antifreeze, replacing the air filter, and inspecting the brake pads. After reaching the time or mileage specified by the manufacturer, a major maintenance is typically performed every 20,000 kilometers. Here is the maintenance required for a car at 25,000 kilometers: Change the engine oil. Replace the engine oil (lubricant) and oil filter: This must be done every 5,000 kilometers or six months. If full synthetic oil is used, it can be changed every 8,000 kilometers at most. Replace the transmission fluid. Changing the transmission fluid is an important task. The transmission is the link between the clutch and the drive shaft, and its internal gears are very precise. Frequent gear shifting can easily cause the transmission fluid to deteriorate, which then fails to provide cooling and lubrication, making the transmission more susceptible to damage. Therefore, it is recommended to change the transmission fluid according to the maintenance manual. Replace the antifreeze. The replacement time for car antifreeze is generally two years, which aligns well with the major maintenance cycle of 120,000 kilometers. Antifreeze usually comes in two colors: pink and blue. Since the cost of antifreeze is not high, it is recommended to replace it according to the car's maintenance manual. Replace the air filter. Replace the air filter and cabin air filter: These should be changed every 20,000 kilometers or two years. Inspect the brake pads. Although there is no fixed requirement for when to replace brake pads, it mainly depends on the car's usage habits. It is recommended to inspect the brake pads when the car reaches 20,000 kilometers. If the brake pads are less than 5mm thick, they need to be replaced. Car maintenance generally includes the following inspection or replacement items: Check if the coolant level meets the specified requirements; inspect the brake and clutch fluid levels; check if the power steering fluid reservoir level complies with the specifications; examine all system oil pipe interfaces for leaks; inspect the battery fluid level and windshield washer fluid level; check the tension and aging of the generator, air conditioning, water pump, and power steering pump belts; ensure all front and rear lights are functional (including headlights, width lights, turn signals, brake lights, reverse lights, and fog lights); check tire pressure and wear, tighten the tire bolts to the specified torque, replenish tire pressure to the model's specified value, and rotate the tires based on wear; verify that the car's exhaust emissions meet standards. Car maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Modern car maintenance mainly includes the engine system (engine), transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down deterioration, and extend the service life.
