What is the appropriate normal tire pressure for the Qashqai?

The normal tire pressure for the Qashqai ranges from 2.3 to 2.8 BAR, and any pressure within this range is considered safe. However, during summer when temperatures are high, the tire pressure, which may initially be within the normal range, can actually rise to above 3.0 BAR after driving. Therefore, in summer, it is advisable to maintain a slightly lower tire pressure within the normal range, ideally between 2.3 and 2.5 BAR. The Qashqai is positioned between a compact SUV and a hatchback. In terms of body dimensions, the Qashqai measures 4315mm in length, 1783mm in width, and 1606mm in height, with a wheelbase of 2630mm.

What is an airbag device?

Airbags, like seat belts, are typical passive safety protection devices. The English name for airbags is SRS, which stands for Supplemental Inflatable Restraint System. The original meaning is Supplemental Restraint System, indicating that airbags are auxiliary and not the primary safety measure. Airbags consist of sensors, microprocessors, electronic control units, airbag covers and support rings, airbags, and airbag modules. During a collision, the sensors detect the intensity of the impact and send the signal to the controller. The controller receives and processes the signal from the sensors. If it determines that the airbag needs to be deployed, it immediately sends an ignition signal to trigger the gas generator. Upon receiving the ignition signal, the gas generator quickly ignites and produces a large amount of gas to inflate the airbag.

What are the symptoms of a clogged expansion valve?

When an expansion valve is clogged, symptoms such as poor cooling effect, frosting behind the valve, and abnormal compressor noise may occur. The expansion valve is a crucial component in the refrigeration system, typically installed between the liquid receiver and the evaporator. It allows medium-temperature, high-pressure liquid refrigerant to pass through its throttling mechanism, transforming it into low-temperature, low-pressure wet steam, which then absorbs heat in the evaporator to achieve the cooling effect. The expansion valve consists of three main parts: the valve body, the temperature sensing bulb, and the balance tube. Features of the expansion valve: 1. It employs an advanced double-flow balanced port structure; 2. The use of a double-flow thermal expansion valve reduces the number of expansion valves, check valves, and solenoid valves required in the refrigeration system; 3. The bidirectional balanced flow port allows the static superheat to vary with changes in the condensing pressure or the pressure drop across the valve port; 4. It maintains stable superheat, ensuring stable system operation; 5. It is suitable for various refrigeration and air conditioning applications.

Can engine oils of different brands be mixed?

Engine oils from two different brands should not be mixed because the additives used in different brands of engine oil vary and can cause chemical reactions, leading to the oil becoming thicker or thinner, partially losing its lubricating properties. Mixing different brands of engine oil can result in: 1. Layering, turbidity, and deterioration of cleaning ability; 2. Abnormal exhaust emissions, as mixing different brands may cause unusual smoke from the exhaust; 3. Formation of sludge, which reduces the cooling effect of the lubricant, leading to higher engine temperatures and potential malfunctions; 4. Accelerated wear, as mixing oils can significantly alter their anti-wear properties, damaging the oil film and increasing the risk of wear between the piston and cylinder wall, potentially leading to piston ring breakage in severe cases.

How to Prevent Rain on Car Rearview Mirrors?

Methods to prevent rain on car rearview mirrors: Before driving in the rain, you can evenly apply soap to the car's rearview mirrors. After the soap hardens, wipe it off with a towel. This will form a wax layer on the glass surface, which has excellent water-repellent properties. Alternatively, you can use a water-repellent spray or solution. Apply it evenly to the rearview mirrors, and it will form a protective film with hydrophobic properties, effectively preventing fogging and ensuring clear visibility. Installing rain guards on the rearview mirrors can also help block rainwater and prevent it from accumulating on the mirror surface. However, rain guards do not solve the issue of fogging on the rearview mirrors.

How to Disable the Anti-lock Braking System?

Method to disable the anti-lock braking system: The ABS (Anti-lock Braking System) cannot be disabled as it is in a default active state. Unless there is a malfunction, the system remains on standby at all times. Whenever there is a tendency for the wheels to lock, the ABS system intervenes to prevent wheel lock-up. The primary function of the ABS system is to prevent the wheels from locking and losing directional control, rather than to shorten the braking distance. In some braking situations where the vehicle cannot come to a complete stop before colliding with an obstacle, the ABS ensures that the driver retains the ability to steer, allowing them to maneuver around the obstacle during braking to avoid an accident.
