A cheap device which can indicate carbon monoxide levels in exhaust emission of internal combustion engines, and hence could be used for adjusting the engine's operating air: fuel mixture ratio, would have widespread application in garages, etc. The instrument described here is sensitive to both unburnt hydrocarbons and carbon monoxide but measures the carbon monoxide to an accuracy well within the tuning capability of most carburation systems.

The Impact

The application of fuels from renewable energy sources for combustion engine powering involves a great demand for this kind of energy while its production infrastructure remains underdeveloped. The use of this kind of fuel is supposed to reduce the emission of greenhouse gases and the depletion of natural resources and to increase the share of renewable energy sources in total energy consumption and thus support sustainable development in Europe. This study presents the results of research on selected performance parameters of transport by internal combustion engines including: power, torque, the emission of sound generated by the engine, the content of exhaust components (oxygen O2, carbon monoxide CO, carbon dioxide CO2, nitrogen dioxide NO2), and the content of particulate matter (PM) in exhaust emission. Three self-ignition engines were tested. The fuel injection controllers of the tested internal combustion engines were additionally adjusted by increasing the fuel dose and the load of air. The material used in the tests were mixtures of diesel oil and fatty acid methyl esters of different concentration. A statistical analysis was performed based of the results. The purpose of the work was to develop a resulting model for assessing the operation of engines fueled with biofuel and diesel mixtures while changing the vehicle's computer software. A computer simulation algorithm was also developed for the needs of the tests which was used to prognose the state of the test results for variable input parameters.

Pressure charging devices in different types of internal combustion engines is allowing to achieve a number of advantages: engine power and fuel effectiveness increasing, exhaust gases toxic reduction etc. Pressure charging systems may be classified by the different parameters. For the time being turbo-supercharger is the most popular unit of serial automobile engines pressure charging. But it has some negative properties. Therefore using of dynamic (acoustic) pressure charging devices is promising solution. Analysis of existing acoustic pressure charging systems is carried out. The perspectives of using of active sound emitters for acoustic pressure charging are described. Theoretical issues of automobile engines active acoustic charging are discussed. Construction of active charging system is suggested. Multifunctional approach to automobile internal combustion engines pressure charging and low frequency intake and exhaust noise reduction is suggested. The results described in this paper may be useful for further development and application of internal combustion engines with improved consumer’s and ecological characteristic.
