【Automotive machining】Electric cars are more efficient than gasoline powered cars

Automotive machining electric vehicles are more environmentally friendly than gasoline driven vehicles, not only because gasoline driven Car dependency rely on fossil fuels, but also because they are more efficient.

Efficiency measures how much energy in the fuel is converted into kinetic energy to cause the tire to roll. No machine can achieve 100% efficiency because heat, friction, and wind resistance always result in some energy loss. But overall, the higher the efficiency, the less energy a car requires. In other words, efficiency means achieving the same performance without consuming more energy.

This is of great significance for moving towards a low-carbon future. Every unit of energy that does not need to be used due to improved efficiency, coupled with our reduced demand for energy, makes it more feasible for renewable energy to dominate our power grid. This means we do more with fewer resources, or create what environmentalist Amory Lovins calls' negative watts'.

Both gas powered and diesel powered automotive machining cars have low efficiency, as they rely on internal combustion engines that generate a large amount of waste heat. There are also many operating components in a hot engine, such as fuel pumps, which consume some gasoline energy but have no effect on the movement of the car. Therefore, cars powered by gasoline can only convert 17% -21% of the available energy in gasoline into kinetic energy. In this analysis, you can see where all the lost energy has been consumed.

Feedback braking, which recycles the energy wasted when using brakes, plays a role in improving vehicle efficiency. Hybrid vehicles possess this performance.

Feedback braking can improve the efficiency of fossil fuel powered vehicles by as much as 21% and 40%. This means that even the most efficient gasoline powered cars can only use about 40% of the available energy stored in gasoline.

By comparison, the efficiency of electric vehicles typically hovers around 60%, and if it includes the effect of regenerative braking, it jumps to about 77% - you should do so because all electric vehicles use regenerative braking. The efficiency of electric vehicles is four times higher than that of regular gasoline powered cars, and twice higher than that of the most efficient hybrid electric vehicles. Therefore, by driving an electric vehicle, you not only reduce your specific demand for oil, but also consume less total energy while driving the same mileage.

There are two significant conclusions regarding this automotive machining efficiency difference.

Cars powered by electricity have lower costs than oil.

Increased environmental benefits of electric vehicles.
