Use of Hydrogen in Fiat Lancia Petrol engine, Combustion Process and Determin...IOSR Journals
To our path towards green economy, Hydrogen is often regarded to have a potential growth in the
coming future. However, the high cost of operation of fuel cell has often been a setback. If we could make use of
hydrogen gas as a fuel directly, the scope of development broadens. Owing to these aspects, this work primarily
focuses on the simulation technique of an Internal Combustion Spark Ignition Engine powered by Hydrogen gas.
The simulations of various stages have been carried out using the discrete approach, thereby investigating the
pressures and temperatures at various instants in the cycle. For the relative performance discussion we have
simulated the different cycles as ideal cycle, air fuel cycle and actual cycle. The resultant cyclic graph indicates
various discrepancies between ideal, air fuel and actual cycle. This analysis serves as a tool for a better
understanding of the variables involved and helps in optimizing engine design and fixing of various parameters,
including the determination of valve timings. Besides this, backfire, is the commonly faced problem with the
hydrogen engines. To reduce this effect, a fuel injectoris used for adding the gaseous fuel to the combustion
chamber.

Sustainable polymers from CO2 and water with low-carbon electricityIlkka Hannula
Within petrochemical industry the combination of synthetic methanol manufacture with MTO technology would make it possible to produce light olefins (ethylene and propylene) CO2 and water with low-carbon electricity. To satisfy global demand (206 Mt/a) of light olefins through P2X route 644 GW electricity and 924 Mt/a CO2 (3 % of annual global emissions) would be required. With today’s electricity market price scenarios the profitability of this concept is however very low in comparison to steam cracking of fossil hydrocarbon feedstocks. Based on cursory capital cost estimates, the levelised production cost of olefins would be 2000 €/t at current electricity prices.

Performance and emission analysis of four stroke twin spark single cylinder S...ijsrd.com
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.

Exhaust Gas Recirculation (EGR) System means to use the Exhaust Gas coming from
Exhaust Manifold to Inlet Manifold in order to reduce the Emission of NOX which is particularly very
harmful. Engine without EGR are more pollutant & uses more atmospherically air for combustion. By
Implementation of EGR system in Engine, the Partial Exhaust Gas is re-circulated again in Engine. The
aim of this work is to review the potential of exhaust gas recirculation (EGR) to reduce the exhaust
emissions, particularly NOX emissions, and to delimit the application range of this technique. The
system is very much Eco Friendly. Using Exhaust Gas Recirculation (EGR) Technique in engines, the
emissions are very much controlled. This method is very reliable in terms of fuel consumption.
EXPERIMENTAL AND NUMERICAL INVESTIGATION OF COMBUSTION BEHAVIOUR IN DIESEL EN...Khatir NAIMA
The aim of this investigation is to evaluate the usability of waste polyethylene oil as an alternative fuel for diesel engines. The novel fuel is obtained by a pyrolysis process of waste polyethylene at 973 K. The obtained oil is tested in a single cylinder air cooled (TS1) direct injection diesel engine at 1500 rpm. Engine performances and exhaust pollutant emissions from Waste Polyethylene Oil (WPO) were analysed and compared to those obtained from the same engine fuelled with conventional diesel fuel. Results showed that the total fuel consumption of WPO is lower than that of neat diesel fuel due to the higher heating value of WPO. Brake Thermal Efficiency (BTE) is improved for WPO especially at low load. The exhaust gas temperature is lower for WPO than that of diesel at low and full load. CO and UHC are found lower, while NOx emissions are higher at high loads. Furthermore, the use of numerical investigation permits to optimize the injection parameters, which can help to take advantages of WPO fuel. The simulation results suggest advancing the injection timing.
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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

28. Conclusions
28
Thermodynamic analyses of a novel configuration (biomass
based indirectly heated combined cycle ) has been carried out in
this paper.
The efficiency of the proposed plant attains a maximum at
particular pressure ratio range (6-9) and individual turbine inlet
temperature (TIT).
For a particular pressure ratio the efficiency value increases at
higher TIT.
Size of the topping cycle components as well as CHX unit
decreases as pressure ratio increases at individual TIT. Also the
size of the said units are getting lowered at higher TIT’s
29. Conclusions
29
Major exergy losses occur at the gasifier, CHX unit, GT & ST
unit and HRSG unit for the plant.
Exergy loss for the other plant components are insignificant.
The exergetic efficiency of the gasifier and the CHX unit are
lower than that of other plant components due to the chemical
reactions takes place at the said units.
The exergy efficiency value of CHX unit is above 90% for the
plant at higher TIT.
