Abstract

The International Maritime Organization (IMO), an apex global maritime regulatory body continuously promotes operational strategies aimed at reduction of Greenhouse Gases (GHG) emissions especially from commercial shipping operations. Shipping companies are responding in a number of ways which includes use of turbochargers as engine enhancers to improve fuel consumption efficiency and hence reduce carbon dioxide emissions. Turbochargers are also attached to enhance the output of internal combustion engines without increasing their cylinder capacity. Recent trends have pointed to increasing use of turbochargers as enhancers to prime movers of marine vessels. This paper analysed the relationship between outputs of turbocharged engine and naturally aspirated one employed as marine vessel prime movers. Data on engine parameters of turbocharged engine and the naturally aspirated one were collected from ship operational log and analyzed using mathematical models. Results showed that for the same sizes of marine engines, the turbocharged engine was more efficient than the naturally aspirated one. Specifically, the volumetric efficiency, the brakepower and the specific power were higher in the turbocharged engine when compared with the naturally aspirated one. Findings showed that turbocharged marine diesel engines based on their higher power output efficiency could continue to dominate naturally aspirated ones in marine prime mover applications. It is recommended that all ship operating companies should adopt turbocharger technology or retrofit their existing fleet to improve operational efficiency.
