| Summary: | The applicability of ISO 8178 C1 eight steady-state emission test cycle to small-scale agricultural machinery diesel engines with huge reserves remains to be discussed, so a diesel engine working condition recorder based on a single chip microcomputer was designed to collect and record the actual working condition information of small-scale agricultural machinery diesel engines. Through data analysis and extraction, a six-condition steady-state emission test cycle suitable for domestic small-scale agricultural machinery diesel engine was proposed and verified by bench test. The results of data analysis showed that the typical working conditions of domestic small-scale agricultural machinery diesel engine were quite different from those of the ISO 8178 C1 eight operating cycle. The results of bench emission test showed that the comprehensive emission level of pollutants of small-scale agricultural machinery diesel engine under the six working conditions was obviously different from that under the ISO 8178 C1 eight working conditions, and in most cases, the emission level under the six working conditions was worse than that under the eight working conditions. The above results can provide some references for the formulation and revision of relevant emission standards and the research on emission control technology of small-scale agricultural machinery diesel engine. |
