A recent announcement that Mazda sees a bright future for ICE is also indicative of the automotive industry has not lost hope in the future of ICE. This paper reports on recent developments to construct a digital twin of these power units with a view to improve their performance and also as a means of monitoring their behaviour when changes are introduced. This paper is composed of two parts. Part 1 is the digital half of an Internal Combustion Engine (ICE) which concerns the development of a mathematical model of the ICE and a suite of computer simulation programs which would allow the effects of various design and operational changes to be reliably and accurately predicted with the ultimate aim of producing cleaner engines and/or more efficient power units. The model has been tested against the experimental results of the Paxman engine at Newcastle University and earlier against the Atlas engine at Ricardo, Brighton, UK and most recently on the TUDEV Engine (2015). Part 2, contains the other digital half of the ICE which describes the rig developments viz., the physical model of an Engine. The key features of both Parts of the paper will e presented at the conference due to commercial confidentiality. However, the idea is to match the two parts using an earlier model developed by Ziarati (2009) to produce a finger print of both the mathematical model and the physical model. The matching of both parts would enable the mathematical model to be used for various design and operational changes with a view to reduce fuel consumption and/or engine harmful emissions. The predicted results and the experimental data are in good agreement.

Fuel consumption is necessary to make work the main and auxiliary systems, electrical and electronic equipment. However, during the process of consumption part of the thermal energy is not used, contributing to environmental impacts. In this context, ships share the concern, and to illustrate this, it is performed an "Economic Profitability and Environmental Impact for the Installation of a Cogeneration System in an Aframax Oil Tanker". From the exhaust gases and implementing thermodynamic techniques it is possible to know the amount of recoverable energy using a gas turbine, steam or combined cycles. The feasibility of its application is based on the fuel saved by not using the auxiliary engines totally or partially, and evaluating in a period of 15 years through financial indexes. Finally, knowing the fuel savings, it is demonstrated how many of air pollutants (CO2, NOX, SOX and PM) would be avoided for installing the cogeneration system.

The maintenance of the propulsion and auxiliary machinery systems has become less important that it deserves, that means while the ship sails everything is supposed to be properly maintained, this is the most extended policy in the Companies and accepted and supported by the Owners. This article studies the deficiencies included in the category propulsion and auxiliary machinery detected by the Port State Control Officers (PSCO) of the Paris MOU area, and tries to demonstrate how important they are in these inspections. At the same time can be seen the professional profile of the PSCO’s as well as the assessment made by them of those areas included in this set of defi...

Taking into account all the above features, there are no studies of the NOx emission engines caused by different working regimes of power because engine manufacturers have not measured these emissions across the range of operating power, but usually we only report the pollution produced by its engines to a maximum continuous power. http://www.transnav.eu the International Journal on Marine Navigation and Safety of Sea Transportation Volume 7 Number 3
