Engine oil serves multiple functions for the engine, including lubrication and friction reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, as well as shock absorption and cushioning. Additional information about engine oil is as follows: 1. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricating oil. 2. Only qualified engine oil can reduce wear on engine components and extend their service life. The engine is the heart of a car, containing many metal surfaces that move against each other in friction. These components operate at high speeds, in harsh environments, with working temperatures reaching 400°C to 600°C.

Is the speed displayed on the car dashboard the instantaneous speed?

The speed displayed on the car dashboard is the instantaneous speed. Speedometer and odometer: The speedometer actually consists of two gauges. One is the speedometer, and the other is the odometer. Traditional speedometers are mechanical. A typical mechanical odometer is connected to a flexible shaft, which contains a steel cable inside. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn rotates a magnet inside the odometer housing. Tachometer: The tachometer is generally located on the instrument panel, placed symmetrically with the speedometer. The tachometer operates based on magnetic principles, receiving pulse signals generated when the primary current in the ignition coil is interrupted. It then converts this signal into a displayable RPM value. The faster the engine speed, the more pulses the ignition coil generates, and the higher the RPM value displayed on the gauge.

Where is the annual inspection for motorcycles in Loudi?

Loudi motorcycle annual inspection is conducted at the vehicle management office. Here is relevant information about motorcycles: Types of motorcycle driver's licenses: Currently, there are three types of motorcycle driver's licenses: F, E, and D. The F license only allows driving lightweight motorcycles with engine displacements below 50CC, but this type of license is rarely pursued. The E license permits driving any two-wheeled motorcycle without displacement restrictions, while the D license allows driving all two-wheeled and three-wheeled motorcycles. Therefore, holding an E license enables driving all two-wheeled motorcycles, as there is no separate license for large-displacement motorcycles. Concept of motorcycles: Motorcycles are vehicles driven by gasoline engines, with handlebars controlling the front wheel for steering. They come in two-wheeled or three-wheeled configurations, offering lightweight agility and rapid movement. Widely used for patrols, passenger and cargo transport, they also serve as sports equipment.

Can I Get Warranty Service at a Local 4S Store If I Purchased the Car in Another Location?

You can get warranty service at a local 4S store even if you purchased the car in another location. During the warranty period, any authorized or manufacturer-recognized service station can perform maintenance, as 4S stores offer nationwide warranty coverage. Generally, when purchasing a car, you need to obtain the vehicle's three-guarantee certificate. As long as you hold this certificate, any 4S store nationwide can provide maintenance and repair services, eliminating concerns about whether the service is local or from another location. Therefore, it is crucial to keep the three-guarantee certificate safe. The car's three-guarantee certificate serves as the manufacturer's warranty basis provided to consumers. The 4S store acts as an intermediary, relaying consumer information to the manufacturer. If the consumer cannot provide the three-guarantee certificate, the manufacturer will not honor the warranty. However, if a 4S store refuses to provide warranty service despite having the certificate or fails to issue the three-guarantee certificate in the first place, these issues can be reported to the manufacturer.

What is the fuel tank capacity of the Huansu S3?

The Huansu S3 comes in 2 models with fuel tank capacities of 55 or 50 liters. The vehicle is equipped with either a 1.5L 113HP L4 engine or a 1.8L 140HP L4 engine, both paired with a 5-speed manual transmission. During actual refueling, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space is designed to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. To check the remaining fuel level, drivers can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates low fuel, while nearing F means the fuel level is sufficient.
