Abstract
Ships are important air pollution sources since their high powered main engines often use heavy fuels. Internal combustion engines are widely used in the shipping sector. Shipping emissions cause significant effects on the environment. In this paper is made an analysis of the thermodynamic efficiency of the Otto Cycle. The eco analysis is made by introducing the efficiencies under maximum power conditions and maximum ecological conditions, and also the heats rejected to the environment under these conditions.
