Hybrid SWOC-AHP Analysis of Two-Stroke Twin Spark Engine

Abstract

A two-stroke engine is a promising device that provides a high power-to-weight ratio in automobiles. In recent times, the twin-spark configuration has shown advantages over the single-spark configuration. However, the rapid combustion associated with the twin-spark configuration leads to a higher NO x emission. Therefore, it is important to determine its strength-weakness-opportunity-challenges (SWOC). It is also important to prioritize the SWOC factors and sub-factors connected with the twin spark two-stroke engine. Thus, the primary aim of the current investigation is to perform the hybrid SWOC-analytical hierarchy process (AHP) analysis for producing the quantifiable priorities for the factors of the two-stroke twin spark configuration. Additionally, the rank-stability of SWOC factors is investigated using sensitivity analysis. From the results, challenge factors emerged to be the most significant, and to counter the challenges, the deployment of opportunity factors showed an improvement in the performance of the twin spark configuration. Moreover, weaknesses attained the least position, which shows a positive perception for developing the future emissions-compliant engine designs. Finally, implementing a twin spark configuration in a two-stroke engine can play a significant role in enhancing its additional benefits.
