Full life cycle carbon emission accounting method for automobile engine cylinder cover

Abstract

The invention provides a full life cycle carbon emission accounting method for an automobile engine cylinder cover. The method comprises the following steps: 1, determining an accounting target, a function unit and a boundary range; step 2, list analysis; step 3, influence evaluation; and 4, result interpretation. According to the method, the life cycle carbon emission of the automobile engine cylinder cover is calculated by adopting an equivalent coefficient method, and factor correction is performed on main materials, so that the method can be better close to the actual production condition, meanwhile, the carbon reduction contribution degree of the recycled materials to the full life cycle of the engine cylinder cover can be identified, resource recycling is promoted, and the economic benefit is increased. Carbon emission of engine cylinder cover products is reduced, enterprises are helped to analyze carbon emission key points, the carbon emission reduction direction is identified, and the purpose of protecting the environment is achieved.

Description

technical field [0001] The invention relates to the field of automobile engine technology and the field of life cycle assessment, in particular to a method for calculating carbon emissions in the entire life cycle of an automobile engine cylinder head. Background technique [0002] With the development of human society, the global climate problem has become more and more serious. Climate warming has become a topic of great concern to all walks of life in various countries. The irreversible risk points related to it have brought many uncertainties to the sustainable development of human beings. my country is the largest automobile manufacturing country in the world. In 2020, the number of automobiles in my country has reached 281 million, with production and sales of 25.225 million and 25.311 million. Life Cycle Assessment (LCA) is a standard evaluation method for ecological design, which has been recognized globally and has been included in the ISO14040 series and GB / T24040 ...
