Abstract

Inconsistent data presently available on the platinum emission rate of cars in Germany equipped with catalytic converters are evaluated. Automobile sources of Pt other than autocatalysts are quantified and found to be 1-6 orders of magnitudes lower than the Pt emissions attributed to catalytic converters. A transfer of emission rates derived from test stand experiments to more realistic street conditions reaches 0.8 microg Pt/km. In this manner, data from test stand experiments and from environmental investigations meet in the range of 0.5-0.8 microg Pt/km.

摘要

目前对德国装有催化转化器的汽车的铂排放量的数据评估不一致。除了自催化剂之外，汽车源的铂被量化，并发现比归因于催化转化器的铂排放量低 1-6 个数量级。从试验台实验得出的排放率转移到更现实的街道条件达到 0.8 微克 Pt/km。通过这种方式，来自试验台实验和环境调查的数据在 0.5-0.8 微克 Pt/km 的范围内吻合。
