Abstract

The invention discloses a cluster tube external combustion engine, which includes a combustion system and a power conversion device. The combustion system includes a combustion chamber, a fuel pipe connected to the combustion chamber, an intake pipe, an igniter, an exhaust duct, a The fuel injector at the end of the fuel pipe; the power conversion device includes a cylinder, a piston arranged in the cylinder, a crankshaft connected to the lower end of the piston, the lower end of the combustion chamber and the upper end of the cylinder connected, a partition wall is provided between the combustion chamber and the cylinder, and a cluster tube is arranged in the combustion chamber. One end of the cluster tube located in the combustion chamber is sealed, and the other end is provided with an opening. The cylinder is connected, and the upper end of the cylinder is provided with a water nozzle on one side and an exhaust valve on the other side. The invention can use various fuels, has a simple structure, is convenient to use, has high utilization rate of heat energy, and is highly efficient and energy-saving.

Description

technical field [0001] The invention relates to an engine capable of using multiple heat energies to perform work, and belongs to the field of engines. Background technique [0002] In the prior art, automobile engine belongs to a kind of very mature technology. Generally, it mainly includes the body, cylinder, piston, crankshaft, connecting rod, valve train, fuel system and so on. Fuel is sprayed into the cylinder through the nozzle, mixed with compressed air to generate hot gas, and the gas expands to push the piston to move in the cylinder to do work, and output power through the connecting rod and crankshaft. Due to the different combustion conditions of different fuels, this kind of engine usually only works best with one kind of gas or liquid fuel, which has strict requirements on the fuel used, and multiple fuels cannot be used in the same engine. On the other hand, the temperature of the cylinder head and the combustion chamber is about 2000 degrees higher than the...
