What does engine braking mean for a car?

Engine braking means: lifting the throttle pedal without depressing the clutch, using the compression resistance generated by the engine's compression stroke, internal friction, and intake/exhaust resistance to create a braking effect on the drive wheels. Here is some relevant information: 1. Modern cars have increasingly powerful engines and higher speeds, while internal friction losses are decreasing, which means the vehicle's own deceleration capability is reduced. At the same time, due to the increase in total vehicle mass, relying solely on the main braking system is no longer sufficient to meet braking demands under high-speed and heavy-load conditions. 2. To ensure safety performance, auxiliary braking systems must be added. Many countries (such as Germany, France, and Switzerland) have made auxiliary braking devices a mandatory requirement for commercial vehicles in their traffic regulations. Currently, the most mature auxiliary braking device used in vehicles is the retarder.

Should a Water-Cooled Motorcycle Be Filled with Water or Antifreeze?

Water-cooled motorcycles should be filled with antifreeze. It is essential to use high-quality antifreeze for water-cooled motorcycles, as adding water can cause rust and corrosion in the radiator and engine. If water is used, over time, scale will gradually form inside the cooling system, becoming thicker and thicker. This reduces the volume of the water passages and slows down the flow of coolant, which affects the dissipation of engine heat, leading to increased engine temperature, reduced power output, and shortened engine lifespan. Introduction to Antifreeze: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Anti-Corrosion Function: Engines and their cooling systems are made of metals, including copper, iron, aluminum, steel, and solder. These metals, when exposed to water at high temperatures for extended periods, will corrode and rust. Antifreeze, on the other hand, not only prevents corrosion in the engine cooling system but also has anti-corrosion and rust-removal properties.

Do I Need to Drain the Original Windshield Washer Fluid Before Adding Antifreeze Washer Fluid?

Under normal circumstances, there is no need to drain the windshield washer fluid before refilling it. It is generally sufficient to add new fluid when the existing one runs out. Windshield washer fluid is a type of liquid used frequently in vehicles, primarily for cleaning the front windshield. Additionally, unlike coolant, windshield washer fluids from different brands can be used interchangeably without causing issues. Pay Attention to the Antifreeze Rating: When selecting windshield washer fluid, it is important to consider the antifreeze rating. Different antifreeze ratings are suitable for different environmental temperatures. There is one situation where it is necessary to drain the existing washer fluid and replace it entirely—when winter approaches. The previously used washer fluid may have a lower antifreeze rating, and in northern regions with extremely low temperatures during winter, it becomes essential to switch to a washer fluid with a higher antifreeze rating. Before replacing, simply spray out the old fluid using the windshield wipers and then pour in the new fluid. Lubrication Effect: Windshield washer fluid offers significantly better cleaning performance than plain water and also provides a certain level of lubrication, which helps slow down the aging process of the wiper blades and reduces the likelihood of clogging the spray nozzles. Therefore, regardless of the situation, it is advisable to use windshield washer fluid and avoid substituting it with tap water.

Why does a car with GPS installed lose power after being parked for a few days?

GPS vehicle tracking devices installed in cars provide real-time positioning. They remain operational at all times, which inherently consumes power. Precautions for installing GPS: Check the power supply wiring of the GPS navigation system. If the power is sourced from a location that remains live after the engine is turned off, such as a car DVD player with a timer function, the GPS will continue to operate even after the vehicle is turned off (you can check if the navigation box feels warm when the power is off). You can modify the power supply location, such as drawing power from the seat heater or the rear end of the ignition switch, so that the navigation system turns off when the engine is off. If the battery drain is not caused by the navigation system, check for issues with the battery, alternator, charging system, or any electrical leaks. Functions of installing GPS: Map query function allows you to search for your destination on the operation terminal. It can record and save the location information of places you frequently visit and share this information with others. It can also query nearby facilities such as gas stations, hotels, and ATMs. Route planning function enables the GPS navigation system to automatically plan a route based on your set starting point and destination. You can set whether to pass through certain waypoints and whether to avoid highways. The speed trap warning function (electronic dog) alerts you with voice notifications if the GPS map contains speed trap information at intersections. If there is no speed trap information in the map, no alert will be given.

What to Do When the Plastic Underbody Shield of a Car is Broken?

If the plastic underbody shield of a car is damaged, it should be repaired or replaced promptly. The plastic underbody shield protects the engine from impact damage while driving and prevents dirt from accumulating on the engine. Here are some relevant details: 1. If the shield is damaged, it should be repaired or replaced at a 4S shop. 2. The original underbody shields are typically made of plastic or resin, which effectively safeguards the engine and the safety of passengers in the cabin. There are also metal underbody shields, which generally do not pose significant issues under normal circumstances. However, in the event of a collision, the engine may impact the metal plate, potentially causing severe harm to the passengers. The underbody shield not only protects the engine from damage but also helps keep the engine compartment clean by preventing dust and mud from entering.

What is the correct usage of D and S gears?

Here is the usage of D and S gears: 1. D (Driving) is the forward gear. When driving in this gear, the hydraulic control system shifts gears according to the preset program, operating entirely based on the set logic—simply press the accelerator. 2. S (Sport) is the sports gear. When engaged, the hydraulic system only connects to the first and second gears of the forward gears, and the automatic transmission can only shift automatically between these two gears, unable to engage higher gears. The upshift is delayed, naturally resulting in stronger power. When shifting from D to S gear, there will be a noticeable downshift phenomenon. This forced downshift is to obtain greater output torque, making the car feel more 'powerful'.
