In this work, an experimental work was carried out to compare the performance of biodiesels made from non edible mahua oil and edible gingili oil in dual fuel engine. A single cylinder diesel engine was modified to work in dual fuel mode and liquefied petroleum gas was used as primary fuel. Biodiesel was prepared by transesterification process and mahua oil methyl ester (MOME) and gingili oil methyl ester (GOME) were used as pilot fuels. The viscosity of MOME is slightly higher than GOME. The dual fuel engine runs smoothly with MOME and GOME. The test results show that the performance of the MOME is close to GOME, at the pilot fuel quantity of 0.45 kg/h and at the advanced injection timing of 30 deg bTDC. Also it is observed that the smoke, carbon monoxide and unburnt hydro carbon emissions of GOME lower than the MOME. But the GOME results in slightly higher NOx emissions. From the experimental results it is concluded that the biodiesel made from mahua oil can be used as a substitute for diesel in dual fuel engine.

Introduction: Thousandths dangerous chemicals are found in cigarette smoke. Each day millions cigarettes are consumed and its smoke is emitted in the atmosphere. Although several studies have been carried out on ciga-rette smoke, there is no reliable emission factor for pollutants emitted from burning cigarette. The aim of this study is to prepare four emission factors to estimate amount of carbon dioxide, carbon monoxide, total hydrocarbons and nitrogen oxides per each cigarette.   Materials and methods: In this study a set of experiments was designed to achieve this aim. Different brands of cigarettes were prepared and then they was burned by a vacuum pump. Their cigarettes smoke was analyzed by a gas analyzer to find the concentration of carbon dioxide, carbon monoxide, total hydrocarbons and nitrogen oxides in the cigarettes smoke. Next, the average emission factor for complete burning of a cigarette was calculated.   Results: High amount of pollutants could be found in cigarette smoke. The results revealed that 0.01 mg of hydrocarbons, 0.13 mg of carbon monoxide, 0.5 mg of carbon dioxide and 0.01 mg of nitrogen oxides are emitted during complete burning of each cigarette.   Conclusion: If the number of consumed cigarettes was available, these emis-sion factors can be used to understand the share of cigarette smoke in air pol-lution of large cities to understand whether cigarette consumption is effective on air pollution.

Bus station activity, transportation operations creates high pollution of carbon monoxide (CO) which is so dangerous for retribution officers of Purabaya bus station, Bungurasih. HbCO level can be affected by long exposure. This research aims to describe exposure to carbon monoxide tested through HbCO in the blood of retribution officers of  Purabaya Bus Station Bungurasih.This is a descriptive research with cross sectional approach and uses x Blood Gas analyzer method. Sample of the research was 12 retribution officersworkingin morning and afternoon shift. Data was analyzed by descriptive tabulation in the form of table.Interview was conducted to determine characteristics of the retribution officers of Purabaya Bus station, Bungurasih.Results showed that retribution officers possessed averageHbCO level of 11.94%, exposure duration per day of > 8 hours was 66.7% and 41.7% officers had smoking habit of ½ - 2 packs/day.It is concluded that HbCO level in officers blood washigher than normal level( > 5%). Improvement is needed in all aspects; all employees working outdoors are recommended to wear mass to filter gases or pollutants in which is harmful for health. They are recommended not to smoke when working. Manager of bus station also needsto do planting in bus station area.

Complex of researches of emissions to the atmosphere causing by automobile transport on the territory of city district Togliatti was carried out. Measurements were carries out by universal portable gas analyzer “GANK-4”. Results of measurements are showing a number of exceeding of admissible norms. It was concluded that atmosphere air near to automobile roads of city district Togliatti with maximal intensity of movement of automobile transportis maximally polluted by carbon monoxide in automobile transport emissions. For determination of volume of emissions of automobile transport on city district Togliatti automobile roads and for further it using as source data during calculations of atmosphere pollutions study of peculiarities of distribution of automobile transport flows (its components and intensity) on the territory of city district Togliatti and of it variations in time was done. In total pollution of the territory of city district Togliatti by emissions causing by automobile transport, may be considered as serious ecological problem. It is necessary to develop and to implement the measures of it complex reduction.

Monitoring of atmospheric gas pollution is one of the most important environmental target. Laser methods are the most effective for remote operational monitoring of atmospheric pollution.One of the most important air pollutants is carbon monoxide.The article analyzes the possibility of laser remote sensing method of carbon monoxide emissions detection in atmosphere.The information parameter measured by the remote sensing laser gas analyzer was assessed for absorption band of carbon monoxide near 2,3 μm.The information parameter that can be used for monitoring monoxide emissions is the ratio of the power of laser signals at the wavelengths 4295 cm-1 and 4370 cm-1.Results of calculations of the information parameter for different sizes of emissions (from 1 m to 100 m) and different content of carbon monoxide in the emission (from 0.01 % to 10 %) were showed.Comparing the information parameter R with its background value shows that carbon monoxide emissions can be monitored.Mathematical modeling was performed for quantitative estimation the reliability of detecting carbon monoxide emissions.The probability of correctly emission detecting (emission detecting when there is one) and the probability of false alarms (emission detecting when there is none) were calculated.Mathematical modelling shows that a laser gas analyzer allows us to detect the carbon monoxide emissions with correct detection probability not less 0,845 and false alarm probability no more 0,243 for carbon monoxide emissions with gas concentration not less  0,1 %  and dimension of emissions cloud not less 10 m. For carbon monoxide emissions with gas concentration not less 1 % and dimension of emissions cloud not less 5 m a laser gas analyzer allows us to detect the carbon monoxide emissions with correct detection probability not less  0,999 and false alarm probability no more 0,001.

Recently, the development of modern equipment and early detection of ignition sources has become relevant due to many fires and the material and human damage caused by them. This study aimed to develop a method of searching for the ignition source by moving a mobile gas analyzer towards increasing the concentration of carbon monoxide (CO) emitted in the initial stages of fire. According to the simplex and Kiefer method, an algorithm based on the spatial detection method and guaranteed trajectory definition was used to move the mobile gas analyzer towards increasing concentration. The dependence of the engine speed on the supply voltage, the angular speed of the engine with the supply voltage, the tractive force at the wing flap frequency, the supply voltage as well as the energy consumed by the engine during propulsion were calculated. To determine the direction of the azimuth towards the movement of increasing the concentration of CO, an equation was obtained that made it possible to determine the concentration of CO as a function of the distance from the carbon monoxide source. A diagram of the gradient dependence on the distance to the ignition point was plotted, and the number of points on the trajectory on which the CO concentration is measured was determined. One way to further improve early fire detection methods is to use mobile gas analyzers in the ignition source movement and determine their coordinates with the increase in CO concentration. However, further development is restricted due to insufficient research on design methods for mobile gas analyzers, communication analysis between subsystems, and calculation methods based on mathematical models that adequately describe the basic modes of movement of mobile gas analyzers.
