this paper describes a study that starts with an analysis of typical energy demand profiles in a hospital setting followed by a case study of a combined cooling, heating, and power (cchp) generation system.cchp is an autonomous system that combines the generation of electrical, heating, and cooling energy.the driving units are two high-efficiency gas engines that produce electrical and heat ene...

This study presents experimental test results of a compressed natural gas (CNG) direct injection (DI) engine, which has been developed by modifying a single cylinder diesel engine. The major modifications are (a) modification of components such as cylinder head, piston etc. and (b) development and deployment of electronic fuel injection system and (c) installation of a capacitive discharge igni...

As text generation systems get more sophisticated and capable of producing a wider syntactic and lexical range, the issue of how to choose among available grammatical options (preferably in a human-like way) becomes more pressing. Thus, devisers of text generation systems are frequently called upon to provide their own analyses of the discourse function of various kinds of alternations. In this...

This paper presents an experimental investigation of various exhaust gas recirculation (EGR) rates on the engine performance like brake thermal efficiency, brake specific fuel consumption and brake power and engine exhaust gas emission parameters like nitrogen oxides(NOx), carbon monoxide (CO), hydrocarbon(HC) and particulate matter (PM) for the fuel used in the engine. Four observations are ma...

In this research, the development of a diesel engine thermal overload monitoring system is presented with applications and test results. The designed diesel engine thermal overload monitoring system consists of two set of sensors, i.e., a lambda sensor to measure the oxygen concentration and a fast response thermocouple to measure the temperature of the gas leaving the cylinder. A medium speed ...

The paper shows a test results of single cylinder, direct injected, self ignited dual fuel engine. One has analysed a combustion parameters calculated on base of recorded indicator diagrams. The comparison included: the ignition delay period, the cylinder pressure, the rate of pressure rise, the average medium temperature, the heat release rate, the total combustion time and the indicated effic...

in this literature, a combined method has been employed to simultaneously reducesmoke (soot) and oxide of nitrogen (nox) and maintain the performance parameters of dieselengine. this includes creating an air jet by designing an air-cell inside the piston body, advancedinjection timing and using cold exhaust gas recirculation. the tested engine was an mt4.244engine that worked as natural aspirat...

nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. on the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. the engine bearings...

Decarbonization of ship power plants and reduction harmful emissions has become a priority in the technological development maritime transport, including ships operating seaports. Engines fueled by diesel without using secondary emission technologies cannot meet MARPOL 73/78 Tier III regulations. The MEPC.203 (62) EEDI directive IMO also stipulates standard for CO2 emissions. This study present...
