Implementation of Improved Marine Engines in National Iranian Tanker Company (NITC) and Its Effect on Energy Consumption and Environmental Pollution

In this study, the performance of two generations of two stroke marine diesel engines namely, conventional and improved engines in terms of energy consumption and environmental concerns was investigated. The engines are operating in National Iranian Tanker Company (NITC). The comparison was made for different operating conditions and in various NITC supertankers, which were equipped with RTA type engine as the conventional type and RT-flex engine as the improved type (i.e. camshaft less). The data collection was performed based on daily fuel consumption and the rated fuel consumption was determined. The study showed that the rated fuel consumption of improved engines has been improved in comparison to conventional type and it is about 700 ton per month. Therefore, significant reduction in air pollution, which is about 38 tons ofCO2 per month, was achieved.
