Abstract: The variable compression
ratio(VCR) is an important part of the energy saving and emission reduction in
automobile,and it is one of the most important technology to improve the
dynamic performance,economic performance and emission performance of
automobile.This paper analyzes the necessity of the application of variable
compression ratio in automobile.And it introduces the meaning of variable
compression ratio,the status of domestic and international research,and
existing problems.This paper systematically summarizes the implementation of
the program of the variable compression ratio and puts forward relevant
proposals.
Keywords: Engine;Variable Compression
Ratio(VCR);Energy Saving and Emission Reduction
