Abstract:

It is of instructive significance for the development of our country vehicle industry to investigate the application ratio trend of vehicle energy conservation technology. Based on statistics from the U.S. Environment Protection Agency, the International Council on Clean Transportation and China Automotive Technology and Research Center, a technology penetration three-stage model (initial stage, quickly develop stage and saturation stage) was proposed. The application of variable valve timing (VVT) technology in America, turbocharging technology, gasoline direct injection (GDI) technology and advanced transmission in China was analyzed
considering the effect of related regulation, original equipment manufactures (OEMs), etc. The result shows that under the double inspiration of fuel economy standard improving and oil price increasing, the growth rate of VVT penetration rose while multi-valve technology remained same in America. EU-Sino, US-Sino and Japan-Sino cars accelerated the adoption of turbocharging technology, GDI technology and advanced transmission in China.

Key words: conventional energy vehicles, energy safety, energy-saving technology, adoption rates, variable valve timing (VVT)
