Diagnosis of the characteristics of a diesel engine using diesel and biodiesel fuel

Mineral fuels can be found in only limited resources. The next big problem is the environment pollution, especially the pollution of the atmosphere by exhaust products. Based on the above mentioned an intensive research into the alternative and if possible renewable energy resources has been conducted. Europe has mostly turned to biodiesel production because of many favours. Since Croatia has similar agro-climatic conditions we have also started a project for the biodiesel production and exploitation as in Europe, especially from oil rape from which also organic waste oils can be used. There are some important assumptions which are unavoidable in this process and they are as follows: farmers should be interested in increasing this production based on financial factors. the technology for biodiesel production should be provided. the users of this fuel have to be reassured based on safe diagnostic factors that this usage has its favourable characteristics This work provides the research results when using biodiesel fuel by diesel engines in the agricultural mechanization.
