TH54212B - How to use the reciprocating internal combustion engine and the engine system - Google Patents

Abstract

The invention provides a mixed system with combustion engine feedback. Inside the piston stroke to increase the output and Thermal efficiency by increasing the feed Fuel without Maximum increase in combustion temperature More than normal levels And reduce emissions such as NOx, by the inside the engine will provide The heat exchanger at the end of the turbine. That use the exhaust connected With the exhaust collector, where the water under critical conditions is between 18 MPa and 22.1 MPa (critical pressure) and has The temperature is between 250 and 580 degrees Celsius, or the water above critical conditions is given. Born by exchange The heat of the water that is fed to The heat exchanger with flue gas where water at low or above critical level is injected into the cylinder in the range 90 ° before upper dead center and 30 ° after upper dead center And the leaven will be injected So that the ratio of Excess air has a maximum output of 1 - 2.5 and a maximum combustion temperature of 1600 - 2000 degrees Celsius.

Claims (1)

1. How to use the reciprocating internal combustion engine which burns the fuel. That is a liquid or gas, such as petroleum fires, hydrogen, natural gas, alcohol and others. And the combustion gas works as a working fluid, where the increased fuel mass and water are sprayed in a lower state. Critical pressure is between 18 MPa and 22.1 MPa (critical pressure) and temperature is between 250 and 580 ° C, or above-critical water (hereinafter referred to as `` critical pressure '').
