Impact on Performance, Emissions and Thermal Behavior of a New Integrated Exhaust Manifold Cylinder Head Euro 6 Diesel Engine

Turbine and exhaust ports thermal insulation impact on the engine efficiency and aftertreatment inlet temperature

“…Exploring the topic of exhaust temperature increase, many studies have undertaken concerns on aftertreatment performance improvement via T 4 and its penalty on engine fuel economy. D'Ambrosio et al [21] designed an intake and exhaust manifold integrated in the cylinder head in order to improve the low-frequency thermal fatigue resistance on the cylinder head. This investigation resulted on a faster aftertreatment warm-up, been able to maintain the same BSFC.…”
