“…Operating parameters of the engine were controlled and the composition of the exhaust gas (gas phase components), smoke values and temperature of the exhaust Tested stone specimens in the chamber gas were continuously measured during the test. The engine operating point was chosen due to the higher k value (Szabados and Bereczky, 2015;Szabados and Merétei, 2015;Ajtai et al, 2016). The most important data of the engine operation can be read on the Table 2.…”

“…Three fuels were tested on a turbocharged diesel engine, and particle size distribution was measured. Ajtai et al [20] studied the effect of fuel type and engine condition on number and size distribution of diesel soot. They found that the biodiesel content in the total fuel amount can modify the characteristics of the exhaust particles.…”

The employment of biofuels in blends with diesel oil proved to attain a reduced environmental impact without compromising the engine performance. Among biofuels, waste cooking oil offers the advantages of its reduced raw material cost in comparison with fresh vegetable oil cost; it also eliminates the environmental impacts caused by its disposal. Although a great number of researches has been devoted to biodiesel combustion in engines and pollutant emissions, few studies can be found on light duty diesel engine equipped with up-to-date technologies. This work aims at investigating the impact of waste cooking oil percentage in blends with diesel oil on the performance and emission characteristics of an up-to-date light and compact common rail diesel engine whose main application is in microcars and in urban vehicles. A comprehensive experimental activity was performed in the engine complete operative field. The comparison of the results with those obtained with standard ultralow-sulfur diesel highlighted that the engine performance was quite similar for B20 and diesel oil. B40 suffered for the lower caloric value in regard to diesel. A reduction in CO and HC was obtained with biodiesel blends, along with an increase in NO x . Particulate emissions were also reduced for biodiesel blends; the mean size of particles was smaller as regards diesel oil.

“…Operating conditions (1300 r/min and 50% load) of the RÁBA D10 UTSLL 160, EuroII engine were controlled and the temperature inside the chamber, gas phase components and k absorption coefficient were continuously measured during the test. The engine operating point was chosen due to the higher k value [18][19][20][21]. The fuel used was gas oil complying with MSZ EN 590 from MOL fuel station.…”

8 different natural stone types were exposed to exhaust gas under laboratory conditions to assess urban stone damage. 3 cm in diameter cylindrical test specimens were made from travertine, non-porous limestone, limestone, rhyolite tuff, sandstone, andesite, granite and marble. The samples were exposed for 1, 2, 4 and 8 hours to exhaust gas that was generated by compression ignition internal combustion engine. The exhaust emission was measured. The operating conditions of the engine were documented and several parameters (weight, density, ultrasonic pulse velocity, capillary water absorption, porosity) were measured before and after exhaust gas exposure. The tests indicate that despite the deposition of soot on the surface a significant material loss was recorded at rhyolite tuff (2m%) and at andesite (1m%). The penetration depth of soot was also different for different lithologies. A correlation was found between the ultrasonic pulse velocity and density of tested stones.
