Providing a thermodynamic model to simulate the spark ignition engine fueled with natural gas and ethanol mixture

author

Abstract:

The use of natural gas as an alternative fuel, in recent decades has been proposed. Good combustion properties and cats less than it could be the perfect choice for the next generation. Simulation models can be of great help engine designers. Simulation models to reduce the time and costs for the development of new engines as well as in identifying the technical value that need special attention in the design, are of great importance. In this study the thermodynamic model for the study of thermodynamic parameters of a spark ignition engine fuel mix methane (C2H6O) and ethanol (CH4) is provided. To simulate the engine, the governing equations for modeling the area of combustion engines can be used. This relationship has become in MATLAB code, and finally by drawing diagrams, are analyzed. The results showed that the addition of ethanol to fuel higher percentages of methane, increasing amounts of pressure inside the cylinder, work and heat output (power stage) as well. However, the energy lost through leakage and most pure methane lowest temperature of the burned area is capable.

Experimental Study of Performance of Spark Ignition Engine with Gasoline and Natural Gas

The tests were carried out with the spark timing adjusted to the maximum brake torquetiming in various equivalence ratios and engine speeds for gasoline and natural gas operations. In thiswork, the lower heating value of gasoline is about 13.6% higher than that of natural gas. Based on theexperimental results, the natural gas operation causes an increase of about 6.2% brake special fuelconsumpt...

An Experimental Investigation of Spark Ignition Engine Fueled with Ethanol/Iso-octane and Methanol/Iso-octane Fuel Blends

Alcohols have been used as a fuel for engines since 19th century. Among the various alcohols, ethanol and methanol are known as the most suited renewable, bio-based and ecofriendly fuel for spark-ignition (SI) engines. The most attractive properties of ethanol and methanol as an SI engine fuel are that it can be produced from renewable energy sources such as sugar, cane, cassava, many types ...

CFD Performance Analysis of a Spark Ignition Engine Fueled by Landfill Gas

Landfill gas (LFG) that is generated in an anaerobic environment in landfills and consists primarily of methane and carbondioxide with small amount of nitrogen and other non-methane gases, could be collected and used to produce energy either by extracting methane or using the landfill gas directly in an internal combustion engine or a gas turbine. It amounts to be a net-negative greenhouse gas ...

Performance of spark ignition engine under effect of friction using gas mixture model

This paper presents the effect of friction on the performance of spark ignition engine using gas mixture as working fluid. The results were compared to frictionless engine. Engine parameters that were studied include equivalence ratio, engine speed, break mean effective pressure (BMEP), and cycle thermal efficiency. It was found for the frictionless engine operating at 6000 rev min and stoichio...
