摘要
针对当前柴油机油耗无外载测定精度低的问题,提出了一种新的无外载测定油耗的方法,即利用排气温度间接测定柴油机的油耗。建立了 S195型柴油机油耗测定模型,优化了温度测定点。试验表明,本方法具有较高的测定精度。
Improving the measuring precision of diesel engine fuel consumption in no-external load method as the main objective,a new method using the exhaust temperature to measure the fuel consumption is proposed.A regressive model of measuring fuel consumption of diesel S195 is presented and the temperature mea- suring point is optimized.A higher precision of this method is verified by experi- ments.
