What Causes Low Tire Pressure in a New Car?

There are three main reasons why a new car may display low tire pressure: the vehicle has been parked for too long, causing the tire pressure to drop; some manufacturers intentionally reduce tire pressure slightly to prevent high-speed driving; or the tire may be damaged, either due to a factory defect or punctures during use. When a new car's tire pressure warning light comes on, it's essential to carefully inspect the tires for any damage. Hazards of Low Tire Pressure in New Cars: Increased Fuel Consumption: Low tire pressure increases the contact area between the tires and the road, leading to greater friction and higher rolling resistance, which naturally results in higher fuel consumption. Reduced Tire Lifespan: Similarly, the increased contact area accelerates tire wear, shortening the overall lifespan of the tires. Higher Risk of Blowouts: The increased friction causes the tires to heat up, making them softer and weaker. When the tires can no longer support the vehicle's load, especially at high speeds, blowouts become more likely. How to Handle Low Tire Pressure in a New Car: If the low tire pressure is due to a minor leak and the tire can still support driving, proceed slowly to the nearest repair shop. If the tire pressure is too low to continue driving, use an onboard air pump (if available) to inflate the tire slightly or replace it with the spare tire before heading to a nearby repair shop. In such cases, it's best to switch to the spare tire to avoid damaging the wheel rims by driving with low pressure.

Manual Transmission: Brake First or Clutch First?

Manual transmission vehicles require pressing the clutch first when stopping. Below is relevant information about manual transmissions: 1. Introduction: A manual transmission is a gear-shifting device used to alter the engine's rotational speed and torque transmitted to the drive wheels. It enables vehicles to obtain different traction forces and speeds under various conditions such as stationary starts, hill climbing, turning, and acceleration, while keeping the engine operating within favorable working ranges. 2. Classification and Structure: Manual transmissions consist of gear transmission mechanisms, transmission housing, and control mechanisms. The gear transmission mechanisms can be classified by the number of forward gears or the form of shafts. Based on forward gears, they can be categorized as three-speed, four-speed, five-speed, or multi-speed transmissions; according to shaft forms, they can be divided into fixed-shaft and rotating-shaft types.

How many degrees should the steering wheel be turned for a right turn in Subject 3?

For a right turn in Subject 3, the steering wheel should be turned when the right front corner of the car is tangent to the roadside (i.e., forming a 180° angle between the right front corner and the roadside) if the turning road is narrow. Below is an introduction to the relevant content of the Subject 3 exam: 1. Exam regulations: The specific subjects of the Subject 3 exam are road driving skills and safety and civilized driving knowledge, with full scores of 100 points each. A score of 90 or above is considered passing. 2. Study hour regulations: Subject 3 consists of a total of 40 study hours, including 16 hours of theory, 4 hours of simulated driving, and 20 hours of practical driving. According to the teaching syllabus, driving training is recorded with a time card, and study hours accumulate. Each student can sign in for a maximum of 4 study hours per day.

What Causes an Automatic Transmission Vehicle to Suddenly Stall While Driving?

Automatic transmission vehicles may suddenly stall while driving due to battery issues, high-voltage circuit faults, or engine fuel line blockages. Battery Issues: When a battery reaches the end of its lifespan, its capacity and output voltage decrease. This can directly cause starter malfunctions, insufficient voltage, and failure of the engine spark plugs to generate sparks. In severe cases, the engine may stall and become difficult to restart. Solution: Replace the battery. High-Voltage Circuit Faults: Inspect the high-voltage circuits for signs of aging, detachment, short circuits, or open circuits. Engine Fuel Line Blockages: Irregular fuel supply can interrupt the engine's stroke, or severe carbon buildup or erosion in the spark plugs can cause unstable ignition, leading to difficulty starting the engine and abnormal stalling when the throttle changes. Solution: Perform regular cleaning and maintenance of the engine's fuel lines (including both fuel supply and lubrication lines), promptly inspect and replace spark plugs, and if necessary, conduct a carbon removal treatment inside the cylinders.

What are the effects of turning on the cold air without AC?

Without turning on the AC, air will blow directly from the vents without being cooled, and over time, it will become increasingly hot. Below is an introduction to how the car's air conditioning works for both cold and warm air: 1. How cold air works: Cold air is formed by compressing the refrigerant to liquefy it, which then evaporates and absorbs a large amount of heat from the air. When the cold air is turned on, the compressor's pulley drives the compressor to work, increasing the engine load and consuming a certain amount of fuel. 2. How warm air works: Warm air comes from the heat generated by the engine during operation. After the engine's cooling system dissipates heat from the engine, a fan directs this heat into the car to create warm air. To get cold air in the car, the AC switch must be turned on, which activates the car's compressor to deliver cold air.
