“…When adjusting ST, the HC reduction was 11.52, 15.16, 21.84, and 43.53% respectively. HC reduction was affected by the decreased amount of carbon molecules in the fuel mixture and the increased combustion and mixing of fuel and air [63]. ST influenced the increase in HC emissions when the engine ignition timing was advanced.…”

The global policy solution seeks to reduce the usage of fossil fuels and greenhouse gas (GHG) emissions, and biogas (BG) represents a solutions to these problems. The use of biogas could help cope with increased amounts of waste and reduce usage of fossil fuels. Biogas could be used in compressed natural gas (CNG) engines, but the engine electronic control unit (ECU) needs to be modified. In this research, a spark ignition (SI) engine was tested for mixtures of biogas and hydrogen (volumetric hydrogen concentration of 0, 14, 24, 33, and 43%). In all experiments, two cases of spark timing (ST) were used: the first for an optimal mixture and the second for CNG. The results show that hydrogen increases combustion quality and reduces incomplete combustion products. Because of BG’s lower burning speed, the advanced ST increased brake thermal efficiency (BTE) by 4.3% when the engine was running on biogas. Adding 14 vol% of hydrogen (H2) increases the burning speed of the mixture and enhances BTE by 2.6% at spark timing optimal for CNG (CNG ST) and 0.6% at the optimal mixture ST (mixture ST). Analyses of the rate of heat release (ROHR), temperature, and pressure increase in the cylinder were carried out using utility BURN in AVL BOOST software.

“…The use of alternative fuels is one of the main solutions allowing the reduction of pollutant emissions nowadays [14]. In many scientific papers the subject of the research is using various alternative fuels [15][16][17], and reduction in the consumption of lubricating oils and plastic lubricants [18]. One of the chief benefits of CNG is that it provides a source of affordable energy [19].…”

Abstract. After Poland's accession to the European Union, CNG supply began to be popularized. Jelcz buses powered by engines using diesel and CNG were used for comparative studies. The analysis was performed based on actual data obtained from the observation of the use of buses in the Municipal Transport Company in Przemyśl (MZK Przemyśl). We present, among other things, a comparative analysis of the direct operating costs of public transport buses powered by compressed natural gas and diesel fuel. CNG as a fuel allows to reduce the emission of harmful substances to the atmosphere, which is not without significance in the case of public transport, and this aspect of CNG gas use should be emphasized the most. The research showed differences in the operation and service of the vehicles powered by CNG installation in relation to the vehicles powered by diesel fuel, which may be important in connection with the conduct of transport activities.

“…The first passenger cars were not subject to any emissions restrictions. The emission problems were of interest to many researchers, for example [1][2][3][4][5][6][7][8][9]. For several years, an important element in those works on car concerns has been the project of replacing vehicles with an internal combustion engine with vehicles with an alternative drive.…”

Every year, there are more and more cars on the roads that cause pollution. To reduce it, conventional vehicles have started to be replaced by electric and hybrid vehicles. Therefore, the average fuel/energy consumption of electric, hybrid, spark ignition and self-ignition vehicles over a test distance of 100 km was investigated. The test results were then compared to the manufacturer's data and the average difference between the manufacturer's data and the test data is shown. The largest average difference in fuel consumption between the manufacturer's data and the test data was observed for hybrid vehicles (over 230 %) and the smallest for electric vehicles (less than 10 %) and spark ignition vehicles (almost 18 %). Considering costs, the largest difference between manufacturer's data and test data is observed, as in the previous case, in electric vehicles (0.25 €) and the largest in hybrid vehicles (almost 6 € per 100 kilometers driven).
