Radiator-Less Liquid Cooling

Abstract

This invention is a simple method that would eliminate the need for a conventional liquid cooling system for an internal combustion engine with compression ignition (no spark plugs). It would replace the radiator, water pump, thermostat, etc. with computer controlled water injectors that fire directly into the combustion chamber(s). The engine control computer would control engine temperature by alternating the firing of the fuel and water injectors. Such an engine would be an internal combustion/steam engine hybrid when it reaches high temperatures.

Claims

1. Radiator-Less Liquid Cooling is a simple method to extract energy from an internal combustion engine by utilizing what would normally be heat loss. Such an engine would have no radiator, water pump, thermostat, etc. The engine temperature would be solely regulated by computer controlled water injectors that fire directly into the combustion chamber(s). The engine control computer would alternate the firing of the fuel and water injectors to regulate engine temperature.

2. Such an engine would be of compression ignition type (no spark plugs).

3. (canceled)

4. (canceled)

5. Such an engine would require a temperature sensor for every cylinder.

6. (canceled)

Description

SUMMARY OF INVENTION

[0006] 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.
