The investigation of modified methodology of Audi 1.9 TDI 1Z diesel engine heat release parameters’ determination is represented in the article. In this research the AVL BOOST BURN and IMPULS software was used to treat data and to simulate engine work process. The reverse task of indicated pressure determination from heat release data was solved here. T. Bulaty and W. Glanzman methodology was modified for purpose to simplify the determination of heat release parameters. The maximal cylinder pressure, which requires additional expensive equipment, was changed into the objective indicator – exhaust gas temperature. This modification allowed to simplify the experimental engine tests and also gave simulation results in an error range up to 2% of main engine operating parameters. The study results are assessed as an important point for the simplification of engine test under field conditions.
