The handbrake acts on the rear wheels. There are 3 main reasons why the handbrake operates on the rear wheels: 1. The rear wheels pose the greatest danger when skidding occurs: When tire slippage happens, longitudinal grip decreases slightly, but lateral grip drops significantly. If the front wheels skid, the car cannot steer and will continue moving in the direction of inertia. If the rear wheels skid, while the front wheels can still control direction, the rear wheels may fishtail severely, causing the vehicle body to spin unpredictably, making it extremely difficult to control the direction of travel. Therefore, rear wheel skidding is most dangerous. 2. Early vehicles were mostly rear-wheel drive, establishing the tradition of rear-wheel handbraking: In early automobiles, the front wheels didn't have brakes, so the handbrake acted on the rear wheels. Even after all four wheels gained brakes, the tradition of rear-wheel handbraking continued. 3. It's more practical to install the handbrake on the rear wheels: Most mechanical handbrake systems use simple drum brakes (parking brakes) where cable tension expands the brake shoes to lock the drum and prevent vehicle rollaway. The rear brake discs can be made relatively small, making it easier to install a small drum brake within the rear disc.

Can the Power Tailgate Be Closed Manually?

Models equipped with power tailgates cannot be closed directly by hand. Here is the relevant information: 1. Principle of Power Tailgate Composition: The basic structure of a power tailgate consists of two core-driven rods. The drive rod, via a spindle drive, is composed of an inner tube and an outer tube. The motor and gear inside the inner tube drive a threaded spindle, which moves along a threaded nut fixed to the inner side of the outer tube. The electric strut uses an electric spindle located inside the motor within the strut to open and close the trunk lid, with springs assisting in the opening operation. 2. Avoid Manual Closing: Models with power tailgates should not be closed directly by hand, as this can cause excessive wear on the internal motor, gears, and telescopic components, thereby reducing their lifespan. It is best to use the switch for opening and closing.

What is the real reputation of the BJ40?

BJ40's reputation is not very good. On December 28, 2013, at the China National Aquatics Center "Water Cube", Beijing Auto's first stylish hardcore off-road vehicle, the Beijing 40 (BJ40), was officially launched. The models released included the Cross Version, Expedition Version, and Cool Wild Version, offering consumers six body color options: Molten Rock Red, Danxia Red, Everest White, Aurora Green, Hill Green, and Polar Night Black. Here are the detailed specifications: 1. Interior: As an off-road vehicle, it doesn’t feature luxurious decorations but adopts a simple and rugged design style reminiscent of the "Wrangler." The switches for the windows and central locking are designed as toggle levers, giving a very retro feel. 2. Powertrain: The Beijing Auto BJ40 is equipped with a 2.4L naturally aspirated engine, delivering a maximum power of 105kW and a peak torque of 217Nm, paired with a 5-speed manual transmission. The vehicle also features a mechanical part-time four-wheel-drive system and adopts a body-on-frame structure. Additionally, the rear suspension of the Beijing Jeep BJ40 uses a five-link non-independent setup, providing better support for extreme off-roading. 3. Features: The Beijing Auto BJ40 is positioned as a hardcore SUV. Its body dimensions are 4350mm in length, 1843mm in width, and 1837mm in height, with a wheelbase of 2450mm—almost identical to the two-door Wrangler.

What Does a Clean Exhaust Pipe Indicate?

A clean exhaust pipe indicates that the vehicle has been driven very little, or that the combustion inside the engine is very efficient. Additional information: 1. Reasons for a blackened exhaust pipe: The exhaust pipe turns black due to the presence of unburned fuel mixture in the exhaust gases, which over time causes the pipe to blacken. A blackened exhaust pipe is normal and should not be used as a sole indicator of the engine's working condition. 2. Measures to reduce exhaust pipe blackening: To maintain the engine in good condition, it is essential to follow regular maintenance schedules, use high-quality gasoline, and ensure the correct gasoline grade is used. Prolonged use of low-quality gasoline can lead to increased carbon deposits in the engine. Excessive carbon buildup may cause engine knocking, which reduces engine power and increases fuel consumption. Knocking is an abnormal combustion phenomenon in the engine, occurring when the piston is in the compression stroke, compressing the air-fuel mixture. During this process, the temperature and pressure of the mixture rise.
