This work is aimed on influence of diesel engine parameters that is used with mixture of gas and diesel fuel. The first part of the article describes diesel fuel systems where small part of diesel fuel is replaced by LPG or CNG fuel. These systems are often called as Diesel-Gas systems. Next part of the article focuses on tested car and measurement equipment. Measurement was performed by common-rail diesel engine in Fiat Doblò. Tests were carried out in laboratories of the Department of Engineering and Automobile Transport at the Mendel University in Brno. They were observed changes between emissions of used fuels - diesel without addition of gas, diesel + LPG and diesel + CNG mixture. It was found that that the addition of gas had positive effect on the performance parameters and emissions.

Keywords: diesel-gas system, diesel fuel, mixture, LPG, CNG, engine parameters, emissions, chassis dynamometer
Grants and funding:

This study was supported by the project no. TP 5/2013 "Application of non-destructive methods of technical diagnostics in Agricultural technology" and financed by Internal Grant Agency Mendel University in Brno; Faculty of Agronomy.
