The increase in NOx levels produced by CNG-fueled engines occurs when the fuel switches from gasoline to gas fuel (CNG). The author changed the otto 4 stroke gasoline engine, into a CNG-fueled motorbike and provided additional cooling in the form of a burst of air to the cylinder block. Changes in engine block temperature are detected using a temperature sensor placed on the engine oil. Bursts of air cooling result in temperature changes in engine oil. Changes in engine oil temperature are accompanied by changes in the resulting NOx emissions. This study shows that with a decrease in engine oil temperature in the combustion engine, NOx emission levels also decrease. From the research results it can be ignored that by providing additional air bursts will be able to reduce NOx emissions by up to 18%

Block Temperature

A model of thermal management for cooling system of aero-piston engine was presented in this study. The models of main parts in this system were also founded. Based on the measured value of temperature and pressure in the cylinder, the heat transfer coefficient between gas-fired and the cylinder wall was calculated by using the empirical formula. A heat transfer boundary condition between fins and cooling air was determined according to various Reynolds number of the air flow. Moreover, the method of finite element analysis was utilized to calculate the temperature of cylinder block. In the specified working condition of some two-stroke piston engine used in the unmanned aerial vehicle (UAV), the calculation and analysis were made to study on the effect of aircrew speed and flight height on the cylinder block temperature, as well as the effect of cylinder block temperature on airscrew speed by the thermal management model. The calculation results show that, as the flight height rises, the cylinder block temperature increases accordingly when engine power and airscrew speeds are kept constant; however, at the same height, the higher the airscrew speed is, the lower cylinder block temperature will be. The cylinder block temperature should be kept stable by regulating the airscrew speed.

The Fe3O4 magnetic nanoparticles obtained by the aqueous coprecipitation method are characterized systematically using scanning electron microscope, X-ray diffraction and vibrating sample magnetometer. These magnetic nanoparticles are spheric, dispersive, and have average grain size of 50 nm. The size and magnetic properties of Fe3O4 nanoparticles can be tuned by the reaction temperature. All samples exhibit high saturation magnetization (Ms=53.4 emu·g-1) and superparamagnetic behavior with a block temperature (TB) of 215K. These properties make such Fe3O4 magnetic nanoparticles worthy candidates for the magnetic carriers of targeted-drug or gene therapy in future.
