摘要
随着排放法规的日益严格,不仅轻型车要求安装车载诊断系统,而且在重型车上安装车载诊断系统也成为必然趋势。笔者详细介绍了柴油微粒过滤器(DPF)和选择性还原催化剂(SCR)的工作原理和监控原理。
Emission regulation becomes stricter day by day. This paper introduces the on - beard diagnostics system into the EU legislation for not only light duty engines, but also for heavy duty engines. It also describes the working principle and monitoring principle of DPF and SCR.
