“…The co-combustion of crude glycerol with other renewable liquids is also a viable option since it does not contribute to CO 2 emissions or increase the concentration of harmful products (SO 2 , NO x , and CO) of combustion. 37,38 Szwaja et al 37 burned glycerol mixed with ethanol in a spark ignition reciprocating engine to analyze the toxic content, combustion thermodynamics, and engine performance in the exhaust gases emitted by combustion.…”

“…It is also used for the production of explosives (nitroglycerin). There are several works as regards to glycerol combustion in IC engines [36][37][38][39][40]. As found from a literary survey, glycerol has a high potential to be implemented as a fuel additive or a secondary fuel for IC engines.…”

The article discusses the possibility of using glycerol as an additive to the engine fuel in order to reduce the tendency of combustion knock, and thus to increase the octane number of a given fuel. Experimental tests were carried out on the UIT-85 research engine with a variable compression ratio from eight to eleven to test the intensity of the knock. The completely renewable fuel—the blend of glycerol with butanol in the ratio of 25 and 75%, respectively—was tested. A comparative analysis of the knock intensity was conducted with gasoline 95 and N-butanol tested as reference fuels. The developed method for knock analysis using the proposed knock indicator was also presented. The experimental results proved the proposed blend of N-butanol and glycerol reduces the knock intensity by more than 50% in the spark-ignition engine at a compression ratio of 10, maintaining engine performance at a similar level as it was for a gasoline-fueled engine. The results confirmed the thesis on the reduction of knock intensity when adding glycerol to N-butanol.

“…Most of the recent studies on internal combustion engines focus on reducing fuel consumption values [1][2][3], reducing exhaust emissions [4][5][6] and improving combustion efficiency by replacing engine materials [7,8]. In the studies conducted at this stage, it is generally stated that the combustion efficiency in the cylinder is increased by coating the piston and valve surfaces with materials with low thermal conductivity with different methods and that there are decreases in exhaust emissions [9].…”

In this study, the thermal analysis of an aluminum piston coated with MgOZrO2 to create a thermal barrier with the COMSOL multiphysics program and the changes in exhaust gas temperature, fuel consumption, and engine torque values obtained as a result of engine test experiments were examined. For this purpose, the MgOZrO2 coated and uncoated piston engine was started with biodiesel and 5% water + 15% ethanol doped biodiesel fuel at engine speeds of 1000 rpm, 1500 rpm, 2000 rpm, and 2500 rpm. In the thermal analysis results obtained in the COMSOL, it was found that the temperature values increased in the upper regions of the coated pistons. Likewise, in engine experiments, increased exhaust gas temperature and engine torque showed a tendency to decrease fuel consumption values. It has been observed that the data obtained in the analysis in the COMSOL program are in parallel with the results of the engine experiments.
