Abstract

The invention discloses a thermal energy power device. According to the thermal energy power device, a gasification reactor composed of gasification sheets and gas holes is arranged at the upper dead center position of an internal combustion engine cylinder block, the gasification sheets are arranged at the upper dead center of the cylinder at intervals, the gas holes are distributed on the gasification sheets evenly, or in an array mode, or in a stagger mode, an atomizer is arranged on a cylinder cover above the gasification reactor, heat absorption sheets are arranged in the gas flow direction of an exhaust passage in parallel, thermal energy of tail gas is absorbed by the heat absorption sheets and then transmitted to the gasification reactor, and an internal combustion engine is wrapped in a heat insulation layer; the added working stroke enables the cylinder block to be cooled, and the compression ratio is high; due to the filtration conducted by a cooler and a liquid storage tank, discharged tail gas is more environmentally friendly than that of an existing engine; tail gas discharged after the cylinder block is cooled is filtered through the cooler and the liquid storage tank, so that noise is eliminated; due to the fact that one working stroke is added, the utilization rate of thermal energy is increased by 20-95%; thermal energy is utilized directly on the exhaust passage, and no heat dissipation water tank is needed.

Description

Technical field [0001] The invention belongs to the field of thermal power equipment, in particular to a thermal power equipment that uses internal combustion engine itself to convert thermal energy into kinetic energy. Background technique [0002] Each working cycle of a four-stroke engine is composed of intake stroke, compression stroke, work stroke and exhaust stroke. For a four-stroke engine to complete one working cycle, the piston needs to go back and forth 4 strokes in the cylinder (ie, the crankshaft rotates 2 revolutions) . Four-stroke engines are divided into four-stroke gas oil engines and four-stroke diesel engines. The main difference between the two is the ignition method. Gas-oil engines are spark plug ignition, while diesel engines are compression ignition. [0003] Four-stroke engines are reciprocating piston internal combustion engines, which are classified into three categories: gas oil engines, diesel engines, and gas fuel engines according to the type of fue...
