Abstract


The article presents the tests of the engine Valmet 320 DS installed in the teststand "Schenck Dynas3 LI 250". For these tests biodiesel produced by JSC Rapsoila was used. The test was carried out causing the engine speed to 2600 rpm and loading gradually to maximum. Torque (Te), engine speed (ne), fuel consumption (Bf), the pressure in the cylinder (Pe) and exhaust gas CO, CO2, O2, HC, NOx were measured. Initially, measurements were carried out using biodiesel (RME). After that, biodiesel was added with the additive Valvoline VPS HD Diesel System Complete keeping a ratio of 100:1. In order to evaluate the effects of additives the engine was working two hours using biodiesel and additive mixture. After two hours the measurements were repeated loading the engine in the same mode. The work presents the results of tests carried out.
