It is powered from the industrial gas system. 13 mPa. Converting an engine to gas fuel causes a number of features of aging of the oil. In operating YaMZ-236Yu diesels in the gas-diesel mode, this process is slowed significantly [1]. However, the design difference in gas-diesel (dual-fuel) engines from ordinary engines is insignificant. The fuel is ignited by an ignition portion of diesel fuel, whose consumption is 20-25% of gas consumption. These engines can be easily switched to operate on diesel fuel alone.

The results are listed in Table 3 and Fig. 3. It is clear that the mixed additives are more efficient in cold filter plugging point depression than MC-MA-MCNR 2 alone. The data in Table 3 and Fig. 3 show that when the EVA concentration increases in the mixed additives, ΔSP increases, and ΔCFPP increases until a certain concentration is reached, above which ΔCFPP starts to decrease.

Transmission electron micrographs of the diesel fuel: a – untreated with additives at –2°C; b – doped with MC-MA-MCNR2 at –2°C; c – doped with EVA at –2°C; d – doped with mixture of MC-MA-MCNR 2 and EVA (4:1) at –2°C.
