What Causes High Idle Speed in a New Car?

High idle speed in a new car is caused by: excessive intake air during idling, excessive fuel injection, or incorrect engine control signals. Idling refers to the operation of the engine under no-load conditions, where it needs to overcome the frictional resistance of internal components and maintain the minimum speed for stable engine operation. The idle speed is adjusted by regulating the throttle opening size and the idle fuel supply. The hazards of high idle speed include: 1. Increased engine carbon deposits; 2. Shortened engine lifespan; 3. Overly rich air-fuel mixture in the engine, which can easily damage the three-way catalytic converter; 4. Loosening of the vehicle's braking system, increasing the risk of accidents; 5. Increased exhaust emissions from the vehicle's cylinders.

Does One Car's Failure to Undergo Annual Inspection Affect Another?

A vehicle that has not undergone its annual inspection on time will not affect the annual inspection of another vehicle. Below is relevant information about it: 1. Application within three months: The owner of the motor vehicle can apply for the inspection compliance mark at the vehicle management office of the registration location up to three months before the expiration of the vehicle's inspection validity period. 2. Application notes: Before applying, the owner must resolve all traffic violations and accidents related to the vehicle. When applying, the owner must fill out an application form and submit the vehicle's license, compulsory traffic accident liability insurance certificate, vehicle and vessel tax payment or exemption proof, and motor vehicle safety technical inspection compliance certificate. The vehicle management office should confirm the vehicle, review the submitted documents, and issue the inspection compliance mark within one day of accepting the application.

Does the car speedometer display average speed or instantaneous speed?

The reading on the car speedometer shows instantaneous speed. Below is a detailed introduction about the vehicle speed sensor: 1. Working principle: The vehicle speed sensor consists of a permanent magnet, magnetic poles, coils, and a gear ring. When the gear ring rotates in the magnetic field, the gap between the gear ring's tooth tips and the electrodes changes at a constant speed, causing variations in the magnetic reluctance of the magnetic circuit. The magnetic flux periodically increases and decreases, generating an induced voltage at both ends of the sensor coil that is proportional to the rate of change of the magnetic flux. This AC voltage signal is directly sent to the car's control computer to ensure stable vehicle performance. 2. Installation location: It is generally installed inside the drive axle housing or transmission housing, with the sensor's signal wires enclosed in a shielded casing.

Should You Cover Your Car with a Car Cover in Summer Heat?

It is possible to cover your car with a car cover in summer heat, but avoid parking the vehicle in direct sunlight. Otherwise, covering the car may actually increase the interior temperature, which can damage the car's paint and even the interior. Additional information: Benefits of using a car cover: 1. Covering your car not only protects it from intense sunlight but also prevents corrosive substances like dust, tree sap, and bird droppings from harming the paint, thus better preserving the finish. 2. Using a car cover in summer heat also helps protect the vehicle's interior, as temperatures inside a car exposed to direct sunlight can reach 70-80 degrees Celsius, while covering the car keeps the temperature around 30-40 degrees, slowing down interior aging. If you use your car frequently, to prevent the interior temperature from rising due to sun exposure, you can install sunshades on the front and rear windshields.

Will 5W30 oil become too thin in summer?

Using 5W30 oil in summer can be too thin. 5W30 is suitable for all seasons and can be used in most regions of China, except for extremely cold or hot areas. For example, in Hainan where summers are particularly hot, it's better to use higher viscosity engine oil. Below is relevant information about choosing engine oil: 1. The selection of engine oil should be based on the requirements of the engine. It's unnecessary to use premium oil in engines with lower requirements, and lower-grade oil shouldn't be used in engines with higher requirements. 2. Multi-grade oil is recommended as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to the characteristics of multi-grade oil, phenomena such as premature darkening and lower oil pressure compared to conventional oil may occur during use, which are normal.

How Often Should a Motorcycle Be Ridden?

Motorcycles should be ridden at least once a month. If left unused for too long, the engine oil will gradually settle into the oil pan, leaving components such as the cylinder head, piston, middle cylinder, and valve train exposed to air without lubrication. Over time, these parts will oxidize. Both gasoline and air contain trace amounts of moisture, which can slowly react with metal surfaces, causing oxidation. Therefore, it is essential to periodically start and run the motorcycle. Motorcycles are two- or three-wheeled vehicles powered by gasoline engines and steered via handlebars. They are lightweight, agile, and fast, making them widely used for patrols, passenger and cargo transport, as well as for sports equipment. A motorcycle consists of five main components: the engine, transmission system, running gear, braking system, and electrical instrumentation.
