What is the reason for a car not having a handbrake?

The absence of a handbrake in a vehicle is merely a misunderstanding caused by insufficient knowledge about the types of handbrakes. All cars are equipped with handbrakes, which come in two forms: the traditional mechanical handbrake, commonly found in most vehicles today—some are operated by hand, while others are engaged by pressing with the left foot—and the electronic handbrake, which is simply a button but functions on the same principle as the former. The traditional handbrake requires the driver to manually release the parking brake or skillfully coordinate the throttle and clutch for a smooth start on slopes. This design might seem like it lacks a handbrake, but in reality, it is equipped with one. The electronic handbrake extends from the basic parking function to the automatic parking feature AUTO-HOLD. The application of AUTO-HOLD automatic parking technology eliminates the need for drivers to maintain prolonged braking when the vehicle is stationary. When the automatic electronic parking brake is engaged, it prevents unnecessary sliding of the vehicle—simply put, the car won't roll backward. The AUTOHOLD automatic parking function utilizes a slope sensor to provide precise parking force through the controller. During startup, the parking control unit, via the clutch distance sensor and clutch engagement speed sensor, automatically releases the parking brake when the driving force exceeds the running resistance, ensuring a smooth start. In daily urban driving, simply enabling the AUTOHOLD function activates the corresponding automatic parking feature. The intelligent AUTOHOLD automatic parking function can automatically engage four-wheel braking when the vehicle is stopped at traffic lights or on slopes, keeping the car stationary even in D or N gear without the need to continuously press the brake pedal or use the handbrake. To release the stationary state, a light tap on the accelerator is sufficient to disengage the brake.

What type of engine oil should be used for the Qidian 150G2?

The Qidian 150G2 motorcycle should use engine oil with a grade of SF or higher, and viscosity grades such as 10W-40, 15W-40, or 10W-30, as long as it is suitable for motorcycles. For example, SL-grade 5W-30 oil can be used. The engine oil used in motor vehicles consists of two parts: base oil and additives. The base oil primarily provides lubrication, while the additives improve the oil's performance and can impart new properties to the base oil. Choosing engine oil: When selecting engine oil for your vehicle, it is important to consider the temperature of the location where the vehicle will be used. Choose oil that is suitable for the engine based on the local temperature. Options include conventional mineral oil, full synthetic oil, and semi-synthetic oil. When categorizing oil for winter and summer use, winter oil should primarily focus on low-temperature viscosity grades, while summer oil, due to higher temperatures, does not require a low-temperature viscosity grade.

What are the standards for pulleys?

.First, standard parts refer to commonly used components (parts) that have been completely standardized in terms of structure, dimensions, drawing methods, markings, etc., and are produced by specialized manufacturers. Standards for pulleys: Standard parts refer to commonly used components (parts) that have been completely standardized in terms of structure, dimensions, drawing methods, markings, etc., and are produced by specialized manufacturers. Diameter of pulleys: The diameter of the pulley at the reference width of the groove. A pulley consists of three parts: the rim, the web (spoke), and the hub. The outer annular part of the pulley is called the rim, which is the working part of the pulley used to install the drive belt and is equipped with trapezoidal grooves.

What Components Make Up the Vehicle Control System?

The vehicle control system includes the powertrain electronic control system, chassis electronic control system, and body electronic control system. Powertrain Electronic Control System: Mainly consists of engine electronic control (including gasoline and diesel engines), automatic transmission control (ECT, CVT/ECVT, etc.), and integrated electronic control of the powertrain assembly. The control system is primarily composed of various sensors, actuators, and electronic control units (ECUs). Chassis Electronic Control System: Includes anti-lock braking and dynamic body control systems (ABS/ASR, ESP/VDC), traction control system, suspension and vehicle height control system, tire pressure monitoring system (TPMS), cruise control system (CCS), steering control system (e.g., 4WS), and drive control system (e.g., 4WD). Body Electronic Control System: Mainly consists of airbags (SRS), automatic seats, automatic climate control, interior noise control, central anti-theft door locks, visibility lighting control, automatic wipers, automatic windows and doors, automatic collision avoidance system, and power management systems for various electrical devices.

Can the transmission oil of Japanese cars remain unchanged?

Japanese cars cannot go without transmission oil changes. Hazards of not changing transmission oil for a long time: damage to the gear shift control mechanism of the transmission; abnormal wear of gears and clutch plates inside the transmission; affecting the normal operation of the transmission, leading to damage of the transmission valve body. The functions of transmission oil: Reduce friction, minimize wear, control the friction of the clutch and the performance of the synchronizer. Load bearing (low speed high torque, vibration load), heat dissipation, reduce vibration and noise, remove contaminants at gear meshing points (cleaning function). Prevent corrosion, prevent pitting and surface metal tearing, isolate metal surfaces, prevent direct contact between metal bodies. The signs that transmission oil needs to be changed are: Body shaking, gear shifting hesitation; transmission high-temperature warning appears on the dashboard; car stalling; abnormal noises occur.

Will the airbag deploy when the car is turned off?

When the vehicle is turned off, the airbag will not deploy. This is because the airbag control unit and collision sensors are not powered, so the airbag cannot function. How airbags work: When a collision occurs, the controller identifies and assesses the intensity of the impact based on acceleration signals from the sensors. If the collision intensity meets the design criteria, the airbag sensor quickly triggers the igniter to detonate nitrogen solid particles, forming a rapidly expanding air cushion to mitigate the impact force on front-seat passengers, primarily protecting their heads from injury. Precautions regarding airbags: When the airbag system activates, it bursts open the airbag cover and inflates instantly, which can impact occupants. The hot gases produced may also cause burns to passengers and the driver. Therefore, while maintaining proper driving posture, the driver should adjust the seat as far back as possible to ensure sufficient space for the airbag to fully deploy and provide optimal protection in the event of an accident.
