Abstract

The paper presents the result of the experimental study of performance of dual fuel biogas-diesel engine converted from a Vikyno EV2600-NB diesel engine. The results show that peak of cylinder pressure and indicated engine cycle work decrease when we reduce CH4 fraction in biogas or/and when we increase the engine speed. At rated speed, indicated engine cycle work decreases 15% as CH4 fraction in biogas falls from 80% to 60%. Indicated cycle work of dual fuel engine reaches peak value as fuel-air equivalence ratio is around 1.1. Maximum brake power of dual fuel biogas-diesel engine fuelled with biogas contain 80% CH4 and 60% CH4 lower than rated brake power of diesel engine in the order 10% and 25%.
