The paper presents the results of numerical modeling of the complete thermal cycle of the Andoria 1hc102 test engine. Modeling was carried out in the AVL Fire program. Modeling was used in order to determine the optimal ignition angle of the test IC internal combustion (IC) engine. Model tests were carried out for the spark ignition (SI) engine to operate with excess air ratio equal to λ = 1.2. As a criterion for estimating the quality of engine operation cycle, a value of maximum indicated pressure and indicated efficiency were taken. An additional criterion taken was the so-called knock combustion that limits engine performance. Courses of heat release rate and total heat release as a result were obtained. Modeling results show that the test engine powered by a lean mixture of λ = 1.2, should work with the ignition advance angle equal to 12 deg before top dead centre (BTDC). At this ignition advance angle in the engine knock occurred and the engine reached the indicated pressure and the indicated efficiency and were equal to respectively 0.82 MPa and 34.6%.
