Design, Development and Analysis of Intake Manifold of Single-Cylinder Diesel Engine

Abstract

Engines are one of the greatest Mechanical Engineering application developed in 90s. Compression ignition engines are very robust, durable and efficient. The volumetric efficiency of CI engine is higher because of absence of throttle losses in comparison to SI engine. The flow of air through the intake manifold considerably affects the power and volumetric efficiency of CI engines. In present investigation, existing intake manifold of CI engine is modified and manufactured by additive manufacturing technique. The optimized design was finalized by undergoing computational fluid dynamic analysis. The new intake manifold is fitted to the engine intake and performance tests were performed. For all load conditions, the volumetric efficiency, brake power and brake thermal efficiency were considerably improved. The brake specific fuel consumption was also reduced.
