| Abstract: | NOx and PM are the critical emissions to meet the legislation limits for Diesel engines. Often a value for these emissions is needed online for on board diagnostics, engine control, exhaust after treatment control, model based controller design or model in the loop simulations. Besides the obvious method of measuring these emissions, a sensible alternative is to estimate them with virtual sensors. |
