FIELD: engines and pumps.
SUBSTANCE: proposed engine comprises diesel and gas fuel feed systems with feed amount regulators, and air feed system. Air feed system consists of air filter, air ducts and intake duct. Mixing chamber with three inlets and one outlet is arranged in air duct downstream of air filter. One of the inlets of mixing chamber incorporates Venturi scrubber and communicates with air filter. Two other inlets communicate with sources of gas fuel with high and low cetane number fuel and incorporate regulator of gas amount fed into mixing chamber. Outlet of Venturi scrubber is arranged behind two inlets that feed gas into mixing chamber. Mixing chamber outlet communicates with engine intake duct.
EFFECT: operation on both diesel and gas fuels, reduced emission of toxic substances.
