1. to examine the preliminary adulterated oil.Adulterated fuel. Caused by mixing oil with cheaper blended adulterated fuel is sold at prices that are slightly higher than type which is illegal because it produces adverse effects in several aspects include:The citizen consumers. It was trick was exploitation from received does not meet the requirements, or low-quality and increased costs in repairing engines damaged and jeopardize the country's overall economy. In addition, low-quality fuel consumption caused by adulterated to cause a loss of engine performance, reduced. Pollution has caused a rise in environmental deterioration.The State. Want to lose revenue from taxation and the oil capital is defined in the highest rate for the type of oil is expensive.The honest trader Must suffer a loss event, which may have reached the stage of liquidation, falling because there is a higher cost burden?Department of energy business has prepared how to check fuel quality, the initial Exchange is to learn, as well as the dissemination to the public who are interested to join the Government to prevent and resolve problems with adulterated oil continues. You can check the properties in the areas which are: How to test various properties above to see details. In the following ways:Gasoline Features: water contamination was found adulterated diesel contamination rotation speed methanol contamination contamination common ethanol fuel mixtures. Lawen solution contaminationCheck-up1. color.Objective: to observe the differences between the different types of oils with different colors.Equipment: bottle/glass (transparent) for the supply of oil.How to check: checks to examine by sight.The criteria considered are: gasoline. There must be yellow.2. appearance.Objective: to observe what other ingredients adulterated oil in the.Equipment: bottle/glass (transparent) for the supply of oil.How to check: checks to examine by sight.The criteria considered are: must be not a cloudy liquid. No separate layers. There is no suspension, and sediments. In case of water contamination in gasoline Looks the same as no grade separation (located below).3. evaporationObjective: to investigate the gasoline may have been adulterated with diesel oil. Or other oil based fuel properties that belong to the compound, which has a rate of evaporation or boiling point varies by gasoline, light oil, there kinds range boiling point for about 30-200° c. It has properties that evaporate kerosene or diesel oil is easier. Which has the higher boiling point ranges are at approximately 180-370 degrees Celsius.Equipment used: white copier paper and oil droplets device that can, for example, the coffee tube.How to check: white paper on gasoline droplets, having diameter of approximately 2.5. Cm, then the timer from the start until all volatile oil droplets. In the case of diesel contamination appear stuck on stains the paper until they clear. Testing should be done in a room with enough light, and there is no wind. The criteria considered are: maximum evaporation time 45 seconds if it exceeds the assumed that gasoline might contain adulterated diesel oil.4. API gravity value.Objective: to determine the specific gravity of the oil-fuel unit is degrees (°), which is set up by the United States National Institute of petroleum (American Petroleum Institute) is a value that represents a heavy-oil lighter. Can be measured by using a tool called haidonmitoe (Hydrometer)Equipment used: 1) 500 ml size measuringThere are 2 types of thoemomitoe haidonmitoe) is located in the. When used to measure the temperature of the API and read the value of the oil, while gasoline is measured using the haidonmitoe range of 49-61 or 59-71.3) thoemomitoe (if no thoemomitoe type haidonmitoe is used) Measuring range temperature 0-150° F4 the conversion table) How to check: 1) shake to test oil samples, into the same meat pour into measuring slightly to clean clean measuring and pouring them and then pour the oil sample to approximately 3 in 4 of the measuring or more little try not to have bubbles.2) then haidonmitoe immersion, gradually letting the float stop independently. Do not cling side of glass measuring3) API gravity readings that underscore the level of haidonmitoe, which corresponds to the oil level (lower curved surface) by the same eye-level oil level and then to save the value (s).4 oil temperature reads) at eye level, while oil dipped in haidonmitoe (lower curve surface) and then save it (haidonmitoe is thoemomitoe is in) or read the temperature of the fluid in the eye level, while oil dipped in thoemomitoe the same level of haidonmitoe and to save the value (s).The criteria considered are: taking the API gravity and temperature values that are read to open the converted table by replacing the API gravity in the top line or bottom and up temperature down vertically on the left or right end of the table. Drag together are the API gravity, temperature 60° F (15.6° C)5. melt inkObjective: to investigate the gasoline was adulterated with oil common ethanol fuel mixtures or adulterated with methanol. Based on the properties of l Ink solvent as koho and unlike gasoline that does not dissolve the ink.Equipment used: 1) copier paper, white 2) any color ballpoint pens (ink types should have a dark color)3) device that can drip coffee tubes such as oil.How to check: 1) using a ballpoint pen, writing a book or images on paper, white 2) drops of gasoline to test the drop of 1 point onto paper that is written with a ballpoint pen.The criteria considered are: gasoline containing common ethanol fuel mixtures, or mail to laphasom final. The books or pictures, drew finds the ink melts and more obvious as the quantity is (which is clearly noticed during ethanol or methanol. Mix is 3 percent or more by volume or higher)Common ethanol fuel mixtures gasFeatures: water contamination was found adulterated diesel contamination contamination quickly. rotating methanol.Check-up1. color.Objective: to observe the differences between the different types of oils with different colors.Equipment: bottle/glass (transparent) for the supply of oil.How to check: checks to examine by sight.The criteria at phichan
