What is the role of the ABS system?

The functions of the ABS system include: Maximizing the effectiveness of the brakes, reducing braking time and distance; effectively preventing vehicle skidding and fishtailing during emergency braking, ensuring excellent driving stability; allowing steering during emergency braking, providing good steering control; avoiding intense friction between the tires and the ground, reducing tire wear. During braking, the ABS system quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve for the wheel that is starting to lock up, and maintains the braking force. If the wheel continues to lock up, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S of 20%), achieving the best braking effect and the highest level of driving safety.

Can a car run without engine oil?

An automobile cannot continue to operate without engine oil. Here are the reasons why a car cannot run without engine oil: Burning of the crankshaft and bearing bush: Engine oil provides excellent lubrication and cooling effects for the engine. If the car is forced to operate without engine oil, the engine components will suffer from mutual friction damage due to the lack of lubrication. Additionally, without the cooling function, during high-speed operation of the engine, phenomena such as burning of the crankshaft and bearing bush are highly likely to occur. Engine seizure: Continuing to drive a car without engine oil can lead to engine seizure due to the absence of lubrication, with the consequences becoming more severe as the oil level decreases. When the engine is started again, dry or semi-dry friction will form between the cylinder and piston, thereby accelerating the wear of components. The starting resistance will also significantly increase, making it difficult to start the engine.

Does the BYD Qin Plus DM-i Have a Transmission?

The BYD Qin Plus DM-i is not equipped with a traditional multi-gear transmission, only a single-speed reducer. The absence of a transmission is the most distinctive feature of the DM-i models, which focus on fuel economy. The elimination of the traditional transmission allows the vehicle to achieve smoother acceleration and faster power response, making the driving experience closer to that of an electric vehicle. The engine only intervenes during high-speed driving or rapid acceleration. Regardless of the speed range, as long as the throttle is engaged, the speed is immediately responsive. The BYD Qin Plus DM-i has dimensions of 4605mm in length, 1878mm in width, and 1643mm in height, with a wheelbase of 2700mm. It is powered by a 1.5-liter naturally aspirated engine, delivering a maximum power of 81kW at 6000 rpm and a maximum torque of 135 Nm at 4500 rpm. The BYD Qin Plus DM-i features front-wheel drive, with a MacPherson strut independent front suspension and a torsion beam non-independent rear suspension, utilizing a unibody structure.

Do Turbocharged Cars Burn Engine Oil?

Turbocharged cars do burn engine oil. The following is an introduction to turbocharging in cars: Reasons for burning engine oil: Because the turbocharger is mainly composed of a pump wheel and a turbine, along with other control components. The pump wheel and turbine are connected by a rotor, which operates at speeds of up to several hundred thousand revolutions per minute. Such high speeds make conventional mechanical needle or ball bearings unable to function properly, so turbochargers generally use full-floating bearings, which are lubricated and cooled by engine oil. Introduction to engine oil for turbocharged engines: It is best to use fully synthetic engine oil for turbocharged engines. Fully synthetic oil is artificially manufactured. It involves chemically decomposing natural substances and then synthesizing them with various other substances to produce synthetic oil. Therefore, fully synthetic oil has more stable chemical properties and lower resistance, which can better protect the engine while reducing fuel consumption.

What Are the Signs That a Car Battery Needs Replacement?

When the indicator eye on the battery turns white, it indicates that the battery needs to be replaced. Related information on battery replacement: Other replacement scenarios: If the car battery is deformed or bulging, it means the battery is no longer usable and poses a significant safety hazard, requiring immediate replacement. If you encounter difficulties starting the car, the battery warning light comes on, or the headlights dim at idle, the battery should be inspected. If any faults are found, it should be repaired or replaced promptly. Tips for extending battery life: Car batteries do not have a long lifespan, and proper usage is essential to effectively extend their service life. When the car is turned off, avoid prolonged use of electronic devices inside the car, and do not leave the air conditioning or headlights on, as this will shorten the battery's lifespan. If the car needs to be parked for an extended period, it is best to disconnect the negative terminal of the battery to prevent it from discharging and to prolong its life.

Under what circumstances is a touch-up pen suitable for use?

A touch-up pen is suitable for small, inconspicuous areas of scratches. Here are some details about touch-up pens: Color difference of touch-up pens: The touch-up pen may produce a color difference with your car's body color, making it look unattractive. It might be better to simply find a place to polish and wax, which could remove the scratch. The purpose of a touch-up pen is to cover exposed metal to prevent rust, and it can also repair regular scratches. However, the color will still differ significantly from the original car paint, so it should only be used temporarily. Characteristics of touch-up pens: Due to usage environment limitations, touch-up pens must have a quick-drying feature at room temperature; otherwise, they may cause dripping or attract dust, affecting appearance. Touch-up pens are formulated with standard colors and have a certain level of universality. However, they cannot perfectly match vehicles with varying degrees of aging, and the color difference may be more pronounced compared to custom-mixed spray paint.
