Abstract Power deterioration is a major problem for diesel engines operating at high altitudes. This problem stems from the limited availability of turbocharger energy, which is not enough to increase the boost pressure to the required level. In this study, a control strategy is introduced in order to achieve engine power recovery at different altitudes. It is shown that as the altitude increases from 0 to 4500 m, the required boost pressure ratio increases from 2.4 to 4.3. The needed turbocharger energy should be increased accordingly by 240%, and the TCC (turbine characterization coefficient) should be adjusted within wide ranges. A… More >
