Experimental Investigation on the Emission Level of a Single Cylinder Petrol Engine with Manifolds of Different Geometry

摘要

Petrol engines have been considered as the most popular engine to be used in automobiles due to their simplicity and easy operations. The main problem of SI engine is to get the homogeneous mixture of fuel and air. Due to the improper mixing of fuel-air mixture, emissions become a great concern for the researchers. This air movement and ensuing in-barrel stream field structure created are extraordinarily impacted by the design of intake manifolds. The study aims at the usage of intake manifolds with different geometries such as convergent, divergent and venture in a single cylinder SI engine. The emission levels of CO, HC and NO_x have been tested for the manifolds with different geometry, and the results have been compared with the existing manifold. The observed emission level for the convergent manifold is less, and it is comparable with the government norms.
