Performance analysis of ic engine using air energizereSAT Journals
Abstract In normal circumstances, due to incomplete combustion, 30% of the fuel remains unburnt and is emitted in the form of black smoke, causing air pollution. Moreover, the carbon originating from incomplete fuel combustions, settles on the spark plug and on the engine piston, thus diminishing the compression capacity of the piston and increasing the friction factor. This rate of carbon deposition increases especially in city driving, as the engine works much of the time at part throttle. Excess carbon decreases the compression ratio of the engine which ultimately robs the engine of its power, due to acute knocking or detonation. The above problem can be reduced to some extent by making use of paramagnetic property of oxygen present in the incoming air i.e. by passing the air through external magnetic field.

Techno-Economic Analysis of Stand-Alone Hybrid Energy System for the Electrif...TELKOMNIKA JOURNAL
This paper explores the potential of use of stand-alone hybrid wind/solar energy system in electrification of calibrating equipment of drilling oil rig in Iran. To achieve this, different hybrid energy system configurations based on calibration equipment demand are proposed. This study puts emphasis on the energy production and cost of energy from both wind turbine and photovoltaic (PV) in the hybrid system. In addition, to make conditions more realistic, the real meteorological data is used for HOMER software to perform the technical and economic analysis of the hybrid system. Results indicate that the PV array shares more electricity production than the wind turbine generator if both wind turbine and PV array are utilized in the wind/solar hybrid system. Moreover, results show that the operational cost will be reduced by the suggested hybrid system.

Eco-sheet: 15 kW induction motor – impact of efficiency increase varies with ...Leonardo ENERGY
The objective of this case study is to analyse the effects of improving the efficiency of a 15kW induction motor in various countries with different energy mixes. The results show that an improvement of efficiency has higher environmental benefits in countries with an electricity generation based on fossil fuels rather than renewable energy sources or nuclear. Electricity mixes from EU25, France, Germany, Poland and Austria were used.
The same efficiency increase (Eff2 to Eff1 class) in a motor leads to a saving of 31 tonnes of CO2 in Poland, but 3 tonnes in France. This contrasts with the reduction of primary energy consumption: 330 GJ in Poland and 415 GJ in France.

An internal combustion (IC) engine has a predominant role in a low power generation and a virtual monopoly in mobile applications today. One of the best methods to improve the engine performance and reduce the exhaust emission in a SI engine is by using introduction of twin spark into the combustion chamber. The main purpose of this study is to investigate the effects of twin spark using CNG fuel in SI engine. The performance and emission analysis of an engine are investigated by experiment with CNG kit and gas analyzer. From this study the fuel consumption is reduce in twin spark arrangement for the same power output as compare to single spark using both of the fuel gasoline as well as CNG. Engine emission is considerably reduced using twin spark plug.
COMBUSTION OPTIMIZATION IN SPARK IGNITION ENGINESBarhm Mohamad
The blending technique used in internal combustion engines can reduce emission of toxic exhaust components and noises, enhance overall energy efficiency and reduce fuel costs. The aim of the study was to compare the effects of dual alcohols (methanol and ethanol) blended in gasoline fuel (GF) against performance, combustion and emission characteristics. Problems arise in the fuel delivery system when using the highly volatile methanol - gasoline blends. This problem is reduced by using special fuel manifold. However, the satisfactory engine performance of the dual alcohol–gasoline blends need to be proved. The test fuels were GF, blend M35g65 (35 % methanol, and 65% GF by volume), blend E40g60 (40% ethanol, and 6o% GF by volume). The blend M35g65 was selected to match the vapor pressure (VP) of GF. The test fuels were a lean mixture with excess-air ratio of λ=1.1. The reaction parameters are taken from literatures and fitting calculations. Mathematical model and Computer software AVL program were conducted on a naturally-aspirated, spark ignition engine. The results show that indicate thermal efficiency (ITE) improved whereas the exhaust gas temperature (EGT) of the blends reduced, which is a benefit that reduces compression work. The regulated emissions were also reported. The blend E40g60 was recommended in preference to use because the former had shortened combustion duration, high energy content and its VP was selectively matched to that of GF's.

ANALYSIS OF EMISSION CHARACTERISTIC OF NM-DIESEL BLEND ON VCR DIESEL ENGINEijmech
The consumption of fuel is increasing resulting in pollution of environment with smoke and NOx due to the
development in automobile and power sector. These emission contents smoke and NOx can be reduced by
adding additives with diesel fuel. As these additives are very costly and hence becomes unviable. These
additives decrease the performance of combustion.
Oxygenated compounds are most widely used among additives. The reason for this is the participation of
their oxygen in reactions leading to better combustion and hence lowering the emission contents the
molecular structure of the oxygen contents of additives directly influence on smoke reduction and the
oxygen concentration of the fuel flame also effects the emission specially Nitro paraffin compound
additives have high oxygen contents is then molecular structure. So we considered as oxygenated
additives.
We have used nitro methane (NM) (2%) as an additives with diesel while analyzing the emission
characteristic on VCR Engine

Soot Formation in Diesel Engines By Using CfdIJERA Editor
In order to meet the stringent emission standards significant efforts have been imparted to the research and
development of cleaner IC engines. Diesel combustion and the formation of pollutants are directly influenced by
spatial and temporal distribution of the fuel injected. The development and validation of computational fluid
dynamics (CFD) models for diesel engine combustion and emissions is described. The complexity of diesel
combustion requires simulations with many complex interacting sub models in order to have a success in
improving the performance and to reduce the emissions. In the present work an attempt has been made to
develop a multidimensional axe-symmetric model for CI engine combustion and emissions. Later simulations
have been carried out. Commercial validation tool FLUENT was used for simulation. The tool solves basic
governing equations of fluid flow that is continuity, momentum, species transport and energy equation. Using
finite volume method turbulence was modeled by using RNG K-ɛ model. Injection was modeled using La
Grangian approach and reaction was modeled using non premixed combustion which considers the effects of
turbulence and detailed chemical mechanism into account to model the reaction rates. The specific heats were
approximated using piecewise polynomials. Subsequently the simulated results have been validated with the
existing experimental values

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
