This invention relates to the manufacture of liquid cooled internal combustion engines with compression ignition (no spark plugs).
The modern method of liquid cooling an internal combustion engine was pioneered during and prior to the first world war. It involves the use of a radiator, water pump, thermostat, etc. to maintain proper engine temperature.
Modern engines have a thermal efficiency of only about 25-40%. “Radiator-Less Liquid Cooling” would significantly raise this number by utilizing what would normally be heat loss.
Many methods have been proposed to extract energy from steam from an internal combustion engine such as patents-U.S. Pat. Nos. 1,324,2183 3,921,404 4,122,803 4,300,353 4,301,655 4,322,950 4,377,934 4,402,182 4,406,127 4,433,548 4,509,464 4,590,766 4,706,462 5,000,003 5,010,852 5,191,766 5,896,746 6,095,100 6,202,782 6,986,252 8,061,140 8,109,097.
Most proposed methods for extracting energy from an internal combustion engine via steam pressure involve a mechanism for ducting steam to a turbine or a mechanism to alternate water and fuel into the combustion chambers. “Radiator-Less Liquid Cooling” differs in that it only requires fuel and water injectors that are computer controlled.
“Radiator-Less Liquid Cooling” is a method to extract steam energy from an internal combustion engine by eliminating a conventional liquid cooling system and replacing it with computer controlled water injectors (1 for every cylinder) that fire directly into the combustion chambers. When the engine reaches high temperatures the engine control computer alternates the firing of the fuel and water injectors thus regulating temperature. Such an engine would have greater efficiency and reduced emissions.
