One is located in the lower left corner of the engine compartment, and another is between the trunk and the rear seats. Battery Introduction: A battery refers to a type of cell that can be reused after being discharged and recharged. Types include lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. In a lead-acid battery, the positive electrode is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. During discharge (use), the positive and negative electrodes react with sulfuric acid to form lead sulfate, and the concentration of the sulfuric acid solution decreases to a certain level, necessitating recharging. Using an external power source to recharge restores the electrodes and solution to their original state, allowing continued use after charging. Battery Working Principle: The negative electrode is made of a lead plate filled with sponge-like lead, and the positive electrode is a lead plate filled with lead dioxide, using a 22-28% dilute sulfuric acid solution as the electrolyte. Electrical energy is converted into chemical energy, and during discharge, chemical energy is converted back into electrical energy. When the battery discharges, metallic lead acts as the negative electrode, undergoing oxidation to form lead sulfate; lead dioxide acts as the positive electrode, undergoing reduction to form lead sulfate. When the battery is charged with direct current, lead and lead dioxide are generated at the two electrodes, respectively.

What Do Car Engine Power and Torque Mean?

Car engine power refers to the amount of work done by an object per unit of time, which is a physical quantity describing the speed of work. Torque refers to the moment output from the crankshaft end of the engine. The relationship between engine power and torque is: power equals torque multiplied by angular velocity. An engine is a machine capable of converting other forms of energy into mechanical energy, serving as the device that provides power to a car, determining its power performance, fuel economy, stability, and environmental friendliness. Engines include: internal combustion engines, external combustion engines, jet engines, and electric motors. Their function is: to serve as the device that provides power to the car and as an energy conversion device, converting the thermal energy of gasoline into mechanical energy by burning and expanding gas in a sealed cylinder to push the piston and perform work.

Can tires stored for seven or eight years still be used?

Tires stored for seven or eight years are not recommended for use. Tires are rubber products and will age even if not used. Continuing to use them poses a risk of blowouts. Below is an introduction to car tires. 1. Tire lifespan: Generally, the lifespan of a tire is 6-8 years, with a maximum of 10 years. For tires older than 6 years, check the edges for rubber cracks. If no obvious cracks are found, they can continue to be used. If numerous cracks are detected, it is advisable to replace the tire. 2. Tire mileage: If the tire has no issues (such as excessive patching, side punctures, etc.), but has been in service for four years, it should be replaced even if the mileage hasn't reached 80,000 kilometers. Similarly, if the mileage reaches 80,000 kilometers before four years, replacement is also recommended.
