【Abstract】 The waste heat characteristic of some type natural gas engine was investigated experimentally, by which the waste heat characteristic and the waste heat data in different working condition are acquired. A second-order bivariate regression model is quoted to express the waste heat indexes based on the analysis of experimental data. The results show that the selected regression model is reliable, which can provide credible data for calculation of engine waste heat utilization.更多还原
