ABSTRACT
Renewable sources for raw materials are reaching more interest in order to fulfilled future demands for sustainable transport development in condition that conventional sources for these raw resources are limited. The use of rapeseed oil to blend Diesel fuel for internal combustion engines seems to be interesting for different reason as: - Diminishing of CO2 emissions by natural circulation; - Rapeseed oil is a renewable source of energy; -The physical and chemical characteristics of this biofuel are similar to Diesel fuel. The paper presents the results of test research by using Diesel fuel blended with rapeseed oil on: -parameters of fuel injections process (ignition delay, needle lift, injection timing and fuel injection rate); -combustion phases (ignition delay, pre-mixed combustion, diffusion combustion and heat release). The paper provides tables and charts that show comparable values using both classical and biodiesel fuels mixtures.
