Methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. Use of biofuels such as methanol for combustion process is associated with positive environmental impacts. Using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. In this paper, methanol was injected into combustion chamber of a ISM 370 HD diesel engine and exhaust emissions of this engine which took advantage of pure methanol were evaluated by using AVL FIRE CFD code software at four engine speeds (1200, 1400, 1600 and 1800 rpm). Additionally, influences of EGR mass fraction and various injection timings were investigated. For validation of simulation, in-cylinder mean pressure and rate of
He is also very playful with Liesel. In a society this shows no harm or non-threatening. While Rosa is argumentative and serious all the time. This may seem threatening to a child. If the child feels threatened then he/she will be scared and there will be no trust involved. The way Rosa demonstrates the same warmth is by slowly stop being argumentative and starts opening her heart to Liesel. Since Rosa over time slowly becomes more caring she starts getting attached to Diesel. Diesel shows kindness to Rosa even if she is argumentative. Also Rosa knows that Liesel and Diesel are best friends.
Diesel has a mark as traditional hydrocarbon structure as conventional fuels. H2O2 freshly reported as fuel combustion enhancer and to be a low-emission high-quality oxidizer. Consequently, this article discusses the influence of hydrogen peroxide (H2O2) combination with diesel in different percentages for combustion and COx, SOx and NOx emissions. A comparative study will be carried out to analyze the effect on direct insertion of H2O2 into the
Methanol is one of the most versatile compounds and one of the top ten chemicals produced in the chemical industry. The methanol industry spans the entire globe, with production in Asia, North and South America, Europe, Africa and the Middle East. Worldwide, over 90 methanol plants have a combined production capacity of about 100 million metric tons (almost 33 billion gallons or 90 billion liters), and each day more than 100,000 tons of methanol are used as a chemical feedstock or as a transportation fuel (60 million gallons or 225 million liters). Methanol is also a truly global commodity, and each day more than 80,000 metric tons of methanol are shipped from one continent to another [24].
Ever since I was about seven years old, motor vehicles and their engines just made a lot of sense to me. Pretty much anything that has a motor and 2 to 4 wheels on it just made sense. I’m choosing to go into a field that I know has a very high outcome for success. Why wouldn’t I choose something that means a lot to me and is pretty much my “get away” from everything. Diesel Technology and pretty much anything involving diesel engines, trucks, cars or whatever it may be, is a growing industry with a lot of options to explore for. There is a saying that goes like this, “The only way to do great work, is to love what you do.” That saying couldn’t be more true to me because I love what I do. I love the smell of an old truck that needs work or
Imagine a fuel that can reduce harmful emissions and boost domestic economy around the globe. A fuel that commit our working demand which must clean, sustainable and made from abundant resources. Methanol is that type of fuel, a globally accessible fuel that already widely used by many countries around the world and it’s making headline around the globe. Methanol is the simplest alcohol fuel and the source of energy for fuel cell. It’s also a basic chemical building block, used in the production of wide range of commodities which touch our daily lives from plastics, solvents to windshield washer fluid. Methanol is producing from wide range of raw materials including biomass, natural gas, coal and even pollution emitted from factories and power plants .Countries around the world already using innovative sources to produce methanol fuel like using the waste from paper production called black liquor to create diesel fuel replacement, byproducts of bio-diesel production are made into bio-methanol, Carbon cycle
To date, when issues related with environment, GHG(Green House Gas), sustainability are gradually concerned, increasing people are pursuing new ways to lower down the negative effect exerted by modern industry. This also attract government’s attention upon encouraging utilization and production of alternative energy and offering financial aid for some newly high-tech companies. One solution to deal with this global concerns is finding or develop alternate fuels to replace the fossil fuels such as biofuels. The utilization of biofuels as energy for transportation is mainly driven by the over-depletion of oil, the concerns about energy consumption and the emission of Green House gas. However due to some barriers, the most recently used biofuels will replace around 10 to 15% of fossil fuels in the field of transportation[2]. [Is it MLA citation style?
Due to the increasing pollution, modern vehicles must meet the increasing emission regulation on the pollutants such as soot, NOx, unburned hydrocarbons, particulate matter and carbon monoxides. Initially, spark ignition engines have been used which has a flame propagating mechanism and the combustion can be controlled by varying ignition timing. The emissions of soot are lower when compared with the diesel engines as the mixture used for the combustion is pre-mixed. At partial load conditions the SI engine has low efficiency which is a major drawback. In the compression ignition (CI) engines the compression ratio is higher than the SI engines. In CI engines the rate of combustion is limited as a part of the fuel mixes well with air and burns fast and for the other
With the growing number of vehicle, energy shortage and environmental pollution have become increasingly prominent. Researches on alternative fuels and advanced engine technology have been conducted intensively in recent year to reduce vehicle emission and achieve high engine efficiency. The Homogeneous Charge Compression Ignition (HCCI) combustion engine which operates on lean mixtures and has a gasoline engine-like mixture forming process and diesel engine-like igniting method receives a growing concern.
Biodiesel, the most commonly used Bio-fuel in Europe, is a oil or fat based fuel used an diesel engines and is very similar to its fossil fuel derived equivalent but with far less emissions. Feedstock’s for Biodiesel include animal fats and various plaint based oils such as soy, flax, sunflower, hemp, algae, and palm oils. These source oils and fats undergo a process known as transesterification where they are reacted with an alcohol (such as methanol) and heat to form fatty acid alkyl esters known as Biodiesel (ABC’s).
Biodiesel is produced from vegetable oils, used cooking oils, and animal fats by the production process called “trans-esterification” to convert those mixtures to the chemicals which have long chain mono alkyl esters or fatty acid methyl esters which can be used as “fuel” for vehicles. Approximately, 100 pounds of vegetable oil react with 10 pounds of alcohol (commonly methanol) in the presence of a catalyst, sodium hydroxide; later, 100 pounds of biodiesel and 10 pounds of glycerol (co-product) can be produced. For the glycerol which can be used for pharmaceuticals and cosmetics. Therefore, biodiesel can be considered as totally natural, alternative fuel source to be available for using in most of
Usage of diesel engine in automobiles is increasing worldwide because of its high fuel efficiency. As the usage increases, the emissions from the exhaust gases also increases which affects the atmosphere, thereby causing environmental issues such as global warming, smog and even acid rain. These emissions are mainly due to non-stoichiometric combustion, dissociation of Nitrogen and impurities in the fuel and air mixture. Major emissions include Oxides of Nitrogen, Oxides of Sulphur, unburnt Hydrocarbons, oxides of carbon and other carbon particles or soot. Significant measures are taken by the automotive industries for several years to reduces the intensity of these exhaust gases. There are two ways of reducing these exhaust gases are
Biodiesel as a vehicle fuel source is the way of the future for America, because it gives citizens freedom. Biodiesel is a fuel similar to diesel derived from a plant source, like corn, used vegetable oil, or even algae. This biofuel is created from renewable resources to replace the low source of fossil fuels that is unfortunately nonrenewable. American society was basically coerced into finding a substitute for depleting fossil fuel reserves. Rising conflict between the United States (U.S.) and Third World Countries has caused the prices of crude oil to go up. Due to these situations society had to come up with a cheaper, renewable source of fuel. Biodiesel is the key to releasing the chains of restraint that have been placed upon citizens by those third world countries.
With all the talk about how bioethanol can help the environment there is also biodiesel and biomass in combination with the ethanol used for the replacement of oil and gas companies. Some people don’t think about how their actions can affect the environment by biomass and biofuels to be replaced using energy and can also replace oil-based fuels. “Biomass resources can be used to produce methanol. The pyroligneous acid obtained from wood pyrolysis consists of about 50% methanol, acetone, phenols, and water (Demirbas and Gullu, 1998; Gullu and Demirbas, 2001). As a renewable resource, biomass represents a potentially inexhaustible supply of feedstock for methanol production.” We need to keep making sure that we don’t forget to protect the environment.
“Methanol,” frequently termed as wood energy is consumed as substitute energy. Such supple-energy automobiles can utilize M85 type of ‘methanol.’ This is a blend of eighty-five out of a hundred of methanol and about fifteen out of a hundred petrol. The other substitute energy is biofuel, which is based on vegetable oils or animal fats. It may also be produced from recycled oils from restaurants after being used for cooking. This calls for engine conversion so that they can burn biodiesel in its pure state (Adrian, 2007). ‘Biodiesel’ can be blended with petrol-diesel and get utilized in original locomotives. It is decomposable, and decreases contaminants (‘particulate’ substance, ‘carbon monoxide,’ and ‘hydrocarbons’) associated with the use of fossil fuels in vehicles. ‘Propane’ can also be used as substitute energy and it is a byproduct of “natural gas.” It is more consumed as energy for cooking and heating and it automobiles it produces fewer emissions than gasoline. Another substitute energy is hydrogen which is mixed with ‘natural gas’ to create substitute energy for vehicles designed with interior incineration locomotive capacities.
Blending ethanol with diesel fuel has several issues in terms of performance and emission lev-els. A number of studies have examined the effect of ethanol on thermal efficiency, brake power, fuel consumption and emission levels. Some research [114, 120, 125, 126] obtained dif-ferent results in terms of performance and emission levels. Most of this research agreed that ethanol causes an increase in fuel consumption (BSFC) and a decrease in the efficiency of the diesel engines. Chen et al. [120] showed that ethanol could decrease some types of emissions such as smoke and PM because high oxygen content helps to complete the combustion. When vegetable methyl ester was added to
