Are New Energy Vehicles Afraid of Water?

New energy vehicles are not afraid of being submerged in water, but they should not remain submerged for extended periods. Below is relevant information about new energy vehicles: 1. Introduction: New energy vehicles refer to automobiles that utilize unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of onboard power devices), integrating advanced technologies in vehicle power control and driving to form vehicles with advanced technical principles, new technologies, and innovative structures. 2. Classification: New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

What is the role of the carbon canister system in an engine?

The role of the carbon canister system in an engine is to introduce vapors into the combustion process and prevent them from evaporating into the atmosphere. The carbon canister contains activated carbon, which has adsorption capabilities. When the vehicle is running or turned off, gasoline vapors from the fuel tank enter the upper part of the activated carbon canister through the pipeline, while fresh air enters from the lower part of the activated carbon canister. When the engine is off, the gasoline vapors mix with fresh air inside the canister and are stored in the activated carbon canister. When the engine is started, the electromagnetic valve of the fuel evaporation purification device, installed between the activated carbon canister and the intake manifold, opens, allowing the gasoline vapors in the activated carbon canister to be drawn into the intake manifold to participate in combustion.

Is the front tire pressure higher or the rear?

Generally, the tire pressure of the front wheels is higher than that of the rear wheels because the front of the car houses the engine, making the front part heavier. This results in slightly higher tire pressure in the front wheels compared to the rear. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; causes steering wheel vibration and deviation, reducing driving comfort; accelerates wear on the central tread pattern, shortening tire lifespan; increases vehicle vibration, indirectly affecting the lifespan of other components; overextends tire cords, reducing tire elasticity and increasing the load during driving; decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to a flat tire. Hazards of insufficient tire pressure: Increases friction with the road surface, raising fuel consumption; makes the steering wheel heavy and prone to deviation, compromising driving safety; increases movement in various parts of the tire, causing abnormal heat due to excessive rolling; reduces the functionality of cords and rubber, leading to delamination or cord breakage and excessive friction with the rim, damaging the bead area and causing abnormal wear; multiplies friction between the tire and the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may result in a flat tire; increases tire deformation, making the sidewalls prone to cracks and generating flexing motion, leading to excessive heat, rubber aging, cord fatigue, and breakage. It also increases the tire's contact area, accelerating shoulder wear.

Which is Higher: Idling Fuel Consumption or Driving Fuel Consumption?

Idling fuel consumption is higher than driving fuel consumption. Here are the extended details: 1. Average Fuel Consumption: The unit of average fuel consumption is L/100km, which represents the average fuel consumption per 100 kilometers. It is a significant reference for measuring how far a car can travel after being fully fueled, indicating the fuel consumed by the car over a specified distance of 100km. Instantaneous fuel consumption, on the other hand, is measured in L/H (liters per hour), representing the fuel consumed by the car per unit of time during operation. When the car is idling in place, it clearly relies on the level of instantaneous fuel consumption. 2. Instantaneous Fuel Consumption: The instantaneous fuel consumption of a car is the ratio of the fuel injection amount per unit time to the distance traveled by the car per unit time. For electronically fuel-injected engines, the fuel supply pressure of the engine's fuel system is constant, and the amount of fuel injected depends on the injection pulse width of the fuel injector, meaning the fuel injection amount per unit time equals the injection pulse width multiplied by the idling time of the car. When the car is idling, the distance traveled per unit time approaches zero infinitely, and the fuel injection amount per unit time divided by an infinitesimal value results in higher fuel consumption the longer the idling time. This is the reason why idling fuel consumption is high when the car is stationary.

How Often Should the Oil in a Dual-Clutch Transmission Be Replaced?

Dual-clutch transmission oil needs to be replaced every 60,000 kilometers. Most dual-clutch transmissions use two types of oil: gear oil and transmission oil. Both types of oil generally need to be replaced together during maintenance. The structure of a dual-clutch transmission is similar to that of a manual transmission, with the only difference being the addition of an extra clutch and a shift control mechanism. There are two types of dual-clutch transmissions: dry and wet. In a dry dual-clutch transmission, the clutch plates are not submerged in transmission oil, whereas in a wet dual-clutch transmission, the clutch plates are submerged in transmission oil.
