Pre-heating Fuel for Charge Homogeneity to Improve Combustion Abstract – The idea of the automobile engine that people have is of one that is bygone. The automobile engine today is the pinnacle of engineering expertise‚ implementing the best of technologies and undergoing the best of manufacturing processes to make the closest possible achievement to perfection‚ from design to combustion. The art of perfection though starts much before the process itself. In case of the automobile engine

help us to calculate the flow rate of the water. It is important to study how to use the Reynolds number to calculate the flow pattern and also the Reynolds numbers can be used to calculate other properties such as density‚ velocity‚ diameter and viscosity. We must understand that Reynolds number is a ratio of inertia to viscous effect of a flow. The experiment was conducted in UNITEN lab with my lab mates and was supervised by my lab instructor Mr. Ibrahim. The procedure and rules which has been taught

concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the experiment: * Butanol (C4H10O) * Ethanol (C2H5OH) * Propanol (CH3CH2CH2OH) * Methanol (CH3OH) * Pentanol (C5H11OH) Costs; they’re always a problem or a benefit. And when they are a problem‚ they must be dealt with accordingly. Fuel is a common problem associated with money‚ and unfortunately‚ it is almost compulsory for people

tartaric acid (11.9 g) was dissolved in 165 ml of methanol. This mixture was heated on a steam bath. Racemic (+‚-) α-phenylethylamine was slowly added to mix well. Solution was allowed to cool for 15-20 minutes to observe crystallization of the salt. After observing the precipitate‚ prims formation that appeared like sand‚ the solution was corked and left at student lockers for a week. After a week‚ solution was poured from the crystals. Methanol (10 ml) was then added to the flask containing

effective and efficient. The most important aspect of the recrystallization technique is the selection of the solvent. A large number of solvents are commonly used for recrystallization of organic compounds. Among these are water‚ ethanol‚ ethyl ether‚ methanol‚ and hexane to name just a few. A solvent‚ which works beautifully for one recrystallization‚ may be totally unsuitable for purification of a different compound - the choice for recrystallization solvent is made on a case-by-case basis. This is because
