The course of combustion process under real conditions of work of a traction diesel engine supplied by mixtures of canola oil containing n-hexane

Abstract

Restrictions for emission of toxic substances of exhaust gases force to conduct research aimed at searching for new types of fuels for powering combustion engines. With reference to diesel engines, the main focus was on acquiring fuels not from petroleum refining, the so-called alternative fuels. While examining these issues, the authors conducted various tests on an engine dynamometer in dynamic and static conditions, in which compression ignition engine was powered by mixtures of canola oil containing n-hexane (in various V/V proportions). Although the results were promising, they did not reflect the work of an engine in real road conditions. This article presents the results of research on traction diesel engine powered by mixtures of canola oil containing n-hexane under real operating conditions, which were reflected in real traffic conditions. Mobile system for engine indicating produced by AVL - Indi Micro 602, which was built in Fiat Qubo 1,3 Multijet, was applied during research. Various thermodynamic parameters of combustion process in various dynamic states, typical for the process of real work of an engine powered by examined mixtures of canola oil containing n-hexane were analysed and compared with parameters obtained while powering research vehicle with diesel fuel.
