Evaluarea performanțelor ecologice ale motorului cu aprindere prin comprimare alimentat cu diverse tipuri de combustibili

Abstract

The research reflected in this study aimed to determine the ecological performance of the compression ignition engine (4DC (110X125) powered by diesel oil, rapeseed biodiesel (B 100) and diesel oil-biodiesel mixture (B20 (diesel oil 80% + biodiesel 20%), B50 (diesel oil 50% + biodiesel 50%)), based on experimental tests at the stand. The purpose was achieved by using a gas analyzer (Car-tec CET 2000) that allowed the measurement of the concentration of pollutant emissions from exhaust gases at various loads and speeds of diesel engine operation. It was established that powering the engine with biodiesel and diesel oil-biodiesel mixture produces a minimal impact on the environment by redu-cing the concentration of harmful substances emitted into the atmosphere.
