Can a swollen car battery still be used?

A swollen battery cannot be repaired and should be replaced immediately. Continuing to use a swollen battery may lead to the following consequences: 1. Polarity reversal: A swollen battery is prone to polarity reversal in later stages, where the positive terminal becomes negative and the negative terminal becomes positive. This can cause the charger to burn out and damage the controller. 2. Fire hazard: If the controller and charger lack comprehensive protection functions, it may also lead to vehicle fires. Additional information: Causes of battery swelling include: Battery swelling is one of the most common battery failures, often appearing as bulging on both sides. The main causes are excessive charging or discharging currents, which rapidly increase the battery's internal temperature. If the gas cannot be vented in time and the pressure builds up to a certain level, swelling or deformation occurs.

How Many Chances Are There for the Subject 2 Test?

For the Subject 2 test, if you fail the first attempt, you are allowed one retake. If you do not attend the retake or fail the retake, the current test session ends, and the applicant must reschedule the test after ten days. Within the validity period of the driving skill test permit, the number of rescheduled attempts for Subject 2 and Subject 3 road driving skill tests cannot exceed five. If the fifth rescheduled test is still failed, the passing scores of other previously passed subjects will be invalidated. The full score for Subject 2 is 100 points, with evaluation criteria set for failing, deducting 20 points, deducting 10 points, and deducting 5 points. The test is considered passed if the following conditions are met: ① For applicants of large buses, trailers, city buses, medium buses, and large trucks, a score of 90 or above is required; ② For other vehicle types, a score of 80 or above is required. The test items for large vehicles (A1, A2, A3, B1, B2) include pole test, hill start, parallel parking, single-plank bridge, curve driving, right-angle turn, narrow gate passage, continuous obstacle course, bumpy road driving, narrow road U-turn, and simulations for highways, continuous sharp mountain turns, tunnels, rain (fog) conditions, slippery roads, and emergency handling. The test items for small vehicles (C1, C2) include reverse parking, parallel parking, hill start (canceled for C2), right-angle turn, and curve driving (commonly known as S-turn), which are the five mandatory items (some regions include a sixth item for highway toll card collection).

Why does Geely car display an airbag malfunction?

The reasons for the airbag warning light to illuminate include: foreign objects, especially metal shavings, around the airbag sensor wiring harness causing a short circuit and triggering a false alarm; errors in the car's ECU sensor data; prolonged parking of the vehicle in a humid environment or moisture in the wiring connectors due to car washing; or a malfunction in the airbag itself, though most cases are caused by loose connectors. Below is a detailed introduction about airbags: 1. Brief Meaning: The airbag system is a passive safety (see vehicle safety performance) protection system that, when used in conjunction with seat belts, provides effective collision protection for occupants. In a car collision, airbags can reduce head injuries by 25% and facial injuries by about 80%. 2. Main Components: Primarily consists of airbag sensors, collision airbags, and electronic control devices. 3. Working Principle: When a collision occurs during driving, the airbag sensor first receives the impact signal. If the impact reaches the specified intensity, the sensor activates and sends a signal to the electronic controller. Upon receiving the signal, the electronic controller compares it with its stored data. If the conditions for airbag deployment are met, the drive circuit sends an activation signal to the gas generator in the airbag module. The gas generator, upon receiving the signal, ignites the gas-producing agent, generating a large amount of gas. After filtration and cooling, the gas enters the airbag, causing it to rapidly inflate through the padding in a very short time, forming an elastic cushion in front of the driver or passenger. The airbag then promptly deflates and contracts, absorbing the impact energy, thereby effectively protecting the head and chest from injury or reducing the severity of injuries.

What is the lifespan of a Mazda rotary engine?

Mazda rotary engines have a lifespan of 100,000 kilometers. The rotary engine directly converts the combustion expansion force of fuel into driving torque, eliminating useless linear motion. Rotary engines of the same power output are smaller in size, lighter in weight, have a lower center of gravity, and produce less vibration and noise. Taking the 2015 manual Mazda6 as an example, its body dimensions are: length 4670mm, width 1780mm, height 1435mm, with a wheelbase of 2675mm, fuel tank capacity of 64 liters, and minimum ground clearance of 150mm. The 2015 manual Mazda6 features a front suspension with double wishbone independent suspension with stabilizer bar, and a rear suspension with multi-link independent suspension.

Does the New BMW 3 Series Have a Fragrance System?

The fragrance system in the new BMW 3 Series is located within the iDrive controller and can be activated directly via the button on the air conditioning panel. The system offers two distinct fragrances to choose from, with the following functions: 1. The fragrance diffuser releases the scent throughout the vehicle, effectively eliminating odors such as leather smells or lingering smoke; 2. Negative ions purify the air, creating a healthier cabin environment. Note that a fragrance cartridge lasts approximately 6 months (under moderate intensity and daily use of 1 hour), so it's necessary to order new cartridges for timely replacement.
