What brand of tire is Discoverer?

Discoverer is a series of off-road and SUV tire products under Cooper Tires. Below is relevant information about car tires: 1. Tire shelf life: The main component of tires is rubber, which has a shelf life, so tires also have a shelf life. Fresh rubber has the best performance in all aspects, hence newly manufactured tires also perform the best. ADAC's research on unused tires produced in different years shows that the longer a tire is stored, the worse its performance becomes. 2. Replacement cycle: Tires are rubber products and will age even if not used. It is recommended to replace tires every four years, and even if the mileage driven within the year is low, they should still be replaced.

What Causes Low Tire Pressure in Cars?

Car tire pressure may be low due to prolonged inactivity or slow leaks in the tires. If the pressure is insufficient, immediate inflation is required. Never operate tires with excessively low pressure as it will compromise vehicle handling and reduce tire lifespan. Tire pressure is crucial - excessive pressure reduces the tire's contact patch with the road surface, diminishing traction which negatively impacts driving stability and control. Conversely, insufficient pressure can cause wave-like deformation during high-speed driving, accelerating tire wear and significantly increasing the risk of blowouts.

What is the formula for engine efficiency?

The formula for engine efficiency is η=W useful/Q heat release. The following is a related introduction to automotive engines: 1. Engine categories: Engines are divided into external combustion engines, internal combustion engines, gas turbines, and jet engines. 2. Technical characteristics of engines: The valve drive mechanism of the engine adopts a hydraulic support roller rocker arm structure, similar to some gasoline engines currently on the market. This requires relatively small driving force, which can reduce engine power consumption and fuel consumption to a certain extent, effectively reducing the overall weight of the vehicle and achieving significant lightweight effects.

Does the deployment of vehicle airbags have a significant impact on the car?

The impact of airbag deployment on a vehicle should be considered from the following two perspectives: 1. If the airbag deploys due to its own design defects or technical malfunctions, this situation does not fall under the category of an accident vehicle, and the impact on the vehicle is minimal. 2. If the airbag deploys due to a collision, other structures of the vehicle are likely to be damaged as well. Below is some relevant information about airbags: 1. Basic information. Vehicle airbags are generally composed of sensors, microprocessors, electronic control units, airbag covers and support rings, airbags, and airbag modules. As a one-time active safety device, once an airbag is deployed due to a collision, it cannot be reused. 2. Vehicle depreciation. Whether an airbag has been deployed is not the key factor in determining a vehicle's resale value. The most important factor is the extent of damage to other structures of the vehicle caused by the impact that triggered the airbag. If the collision results in irreversible structural damage to the engine or the vehicle's body, the vehicle is then classified as a major accident vehicle, leading to a more significant depreciation in value.
