Abstract: A high-pressure gas compression-ignition engine includes a cylinder block, a piston and a cylinder head, the piston is mounted on the cylinder block and sealed by the cylinder head to form a combustion chamber for fuel work, and the cylinder head is respectively provided with an intake valve and an exhaust valve. It also comprises a fuel supply system, the fuel in the tank is pressurized by the pump body through a fuel channel and then supplied to the combustion chamber of the cylinder block; a fuel injection device for injecting fuel into the intake valve; a compression-ignition system, which is connected to the exhaust duct or the external air source, and recovers or sucks part of the tail gas energy discharged from the power stroke of the combustion chamber into the external air source, and stores it in the compression-ignition gas storage tank after compression.
