What Does High Vehicle Energy Demand Mean?
2 Answers
High vehicle energy demand means insufficient power in the car. The car engine is the main component that provides power to the vehicle. Below are detailed explanations about car engines: 1. Overview: A car engine is a device that provides power to the vehicle, determining its power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid engines, among others. 2. Others: Common gasoline and diesel engines belong to reciprocating piston internal combustion engines, which can convert the chemical energy of fuel into mechanical energy for piston movement and output power externally. Gasoline engines have high rotational speeds, are lightweight, produce less noise, are easy to start, and have low manufacturing costs. Diesel engines have a high compression ratio, high thermal efficiency, and better economic performance and emission performance compared to gasoline engines.
High vehicle energy demand means that when driving, the car requires more fuel or electricity to maintain operation, such as when climbing hills, accelerating, or carrying heavy loads, causing the engine or motor to increase power output. This leads to a sharp rise in fuel consumption or rapid battery drain, and you can clearly hear the engine roar and feel the car struggling while driving. Common causes include excessive speed, low tire pressure, high air conditioning usage, or excessive load; it often occurs in urban traffic congestion or during highway overtaking. From experience, I've learned that gently pressing the accelerator, maintaining a steady speed, and regular engine maintenance can reduce demand, saving fuel and avoiding frequent refueling hassles. When choosing a car, note that smaller-displacement automatic cars generally have lower demand. In short, high demand not only costs more in fuel or charging but may also affect the vehicle's lifespan, so timely adjustment of driving habits is wise.
