The article discusses the use of liquefied petroleum gas (propane) as the main type of fuel for internal combustion engines operating on the diesel cycle. There has been worked out a technology of the application of this gas, with the main feature being the supply of a mixed fuel of liquefied petroleum gas and an ignition dose of diesel fuel, in proportions of 80-85 % and 15-20 % respectively, from a single fuel tank through the original high-pressure fuel pump and mechanical nozzles without additional installation of gas fuel injectors. The use of this technology makes it possible to reduce the fuel costs, and, consequently, transportation costs for all goods and services, as well as ensure environmental safety even for old vehicles. The cost of converting a diesel engine to use propane as the main fuel is an order of magnitude lower than that of gas-diesel counterparts using compressed natural gas.
