Are energy-efficient vehicles issued blue or green license plates?
1 Answers
Energy-efficient vehicles are issued green license plates. Below are specific details about energy-efficient vehicles: 1. Basic Introduction: Energy-efficient vehicles refer to those with internal combustion engines as the primary power system, whose comprehensive fuel consumption under working conditions is better than the target value for the next stage. One-quarter of the world's energy is used for transportation, including two-thirds of the annual oil production. 2. Energy-saving Technologies: Automotive energy-saving technologies are used to improve vehicle energy consumption. Effective measures include the following aspects: rational matching of highways and transportation facilities, on-demand production and configuration of vehicle models and fuel types, and reasonable operation among other non-technical issues. From a technical perspective, ensuring product quality, using and maintaining machines according to specifications, and changing the combustion method of gasoline engines to improve energy conversion efficiency are crucial. Under the existing combustion methods, improvements can be made to the fuel supply system, such as modifying gasoline engines to cylinder fuel injection, which can enhance gasoline combustion efficiency.
