The influence of turpentine additive on the ecological parameters of Diesel engines

Abstract

After Lithuania’s accession to the EU it is very important to use a larger amount of renewable fuel. Based on economic and environmental considerations in Lithuania, we are interested in studying the effects of turpentine contents in the blended turpentine-diesel fuel on the engine performance and pollutant emission of compression ignition (CI) engine. Therefore, we used engine test facilities to investigate the effects on the engine performance and pollutant emission of 5 % turpentine in the fuel blend. The tests were carried out in the laboratory on an engine dynamometer of the car Audi 1Z and tractor D21 diesel engines. The experimental results showed that turpentine used in the fuel blend for these diesel engines had a positive influence on the engine performance and exhaust emission.

Straipsnyje trumpai apžvelgiami naudojami degalai ir nepageidautinos motorizacijos tendencijos. Pateikiama atsinaujinančių degalų – terpentino priedo poveikio tyrimų laboratorijoje metodika. Dviem režimais bandyti du varikliai: automobilio ir traktoriaus, kai yra fiksuotieji sūkiai, o apkrova – kintamoji. Bandymų rezultatai rodo automobilio ir traktoriaus variklių ekologinių rodiklių pokytį įmaišius į dyzeliną terpentino. Tai galima paaiškinti degimo proceso pasikeitimu.
