marine Diesel Engine failure simulator based on thermodynamic model
Applied Thermal Engineering, 2018Co-Authors: Jose Antonio Paga Rubio, F Veragarcia, Jose Hernandez Grau, Jose Munoz Camara, Daniel Albaladejo HernandezAbstract:Abstract The Diesel Engine is a widely used machine in naval sector both as a propeller and auxiliary generator sets, being the most critical equipment of vessel platform. Therefore, Diesel Engine reliability optimization has a transcendental impact on vessel availability, safety and life cycle costs. This article describes the development of a 4-stroke high speed marine Diesel Engine failure simulator used in military and civil vessels as the main Engine of small patrols and yachts and as an auxiliary genset for larger vessels. Failure simulator is based on a one-dimensional thermodynamic model developed in AVLBoost©, adjusted and validated with experimental data from a real Engine in a test bench. The developed model is able to reproduce with confinable results the effect of a large number of typical thermodynamic failures, the behavior of the Engine and the effects over several parameters measured and non-measured. Therefore, it is possible to obtain the Engine response to failures without having to provoke them in real Engine and also it is possible to know the symptoms of one failure before this failure becomes dangerous for the correct behavior of the Engine. In addition, this paper exposes a methodology which allows to obtain a failure simulator of any marine Diesel Engine. This simulator is able to identify Diesel Engine symptoms under failure condition and build a reliable failure database for diagnosis purposes.

Thermodynamic analysis of combined Diesel Engine and absorption refrigeration unit—naturally aspirated Diesel Engine
Applied Thermal Engineering, 1997Co-Authors: Mahmoud Mostafavi, Brian AgnewAbstract:An analysis based on the laws of thermodynamics has been used to establish the amount of net work, efficiency, and the temperature of exhaust gases of a Diesel Engine (ideal cycles) as a function of pressure ratio and temperature ratio of the cycle. As a result the magnitude of the thermal energy available and the energy recoverable from the exhaust gases to drive an absorption refrigeration unit have been calculated. The variations of efficiency and net work of the Diesel Engine at different configurations as a function of cycle pressure ratio are given, a diagram has also been plotted for the amount of cooling capacity available for air-conditioning purposes.

Thermodynamic analysis of combined Diesel Engine and absorption refrigeration unit—supercharged Engine
Applied Thermal Engineering, 1996Co-Authors: Mahmoud Mostafavi, Brian AgnewAbstract:Abstract This paper describes an attempt to calculate the amount of network, efficiency and also cooling capacity available in the exhaust gases of a supercharged Diesel Engine (ideal cycle) that is interfaced with an absorption refrigeration unit. An air standard cycle is assumed for the Diesel Engine. The variations of net work and efficiency of the Diesel Engine as a function of cycle pressure ratio and temperature ratio are calculated.

Performance Study on Intake System of TBD620 Diesel Engine
Diesel Engine, 2004Co-Authors: Wu Rui-linAbstract:The theoretical and experimental study on intake system is given for TBD620 Diesel Engine. A great deal dataobtaining from the stead flow test of the cylinder head intake port illustrated that the preferable intake swirl can be obtainedand low load performance of the heavy-duty Diesel Engine is improved only adopting the single swirl intake port and thedirect intake port incompletely closed, when the TBD620 Diesel Engine working in the low load condition and less charge.
