Definitions
- the present invention relates, in general, to internal combustion engines and, more particularly, to an apparatus for generating power using heat of both cooling water and exhaust gas discharged from cylinders of such an internal combustion engine, the apparatus leading high temperature cooling water from the water jacket of the engine into a boiler and heating the water using heat of exhaust gas from the combustion chamber of the engine, thus primarily generating highly pressurized hot steam within the boiler and secondarily operating a turbine using the steam to generate power usable as a power source for additional drive parts.
- internal combustion engines are prime movers in which fuel, such as gasoline or light oil, is burnt within combustion chambers of cylinders to generate high temperature and highly pressurized gas having thermal energy. Within such an engine, the thermal energy of the gas is converted into mechanical energy or power to produce force and motion.
- fuel such as gasoline or light oil
- Such internal combustion engines are typically classified into several types: gas engines, gasoline engines, diesel engines, hot bulb engines, kerosene engines, and etc., in accordance with the fuel.
- Such engines are typically cooled by water except for the case of some specifically designed engines.
- a conventional four cycle engine As shown in the drawing, the engine comprises a cylinder 11, and a piston 12 movably received in the cylinder 11.
- a connecting rod 13 is connected to the piston 12 and a crank shaft 14 at both ends thereof to transmit the motion and force of the piston 12 within the cylinder 11 to the shaft 14 while converting the reciprocating action of the piston 12 into a rotating action of the shaft 14.
- a cam 15 is interiorly and rotatably mounted to the lower portion of a cylinder block, with a tappet 16 seated on the cam 15 to operate an elongated push rod 17.
- the push rod 17 is raised or lowered, thus operating a rod arm 18 to open or close a valve 18' seated in a cylinder head.
- the above valve 18' thus allows pressurized mixed fuel, consisting of fuel mixed with combustion air, to be introduced into the upper chamber of the cylinder 11.
- the mixed fuel within the cylinder 11 is ignited by the spark of an ignition plug 19, thus being exploded to make the piston 12 linearly reciprocate within the cylinder 11.
- a water jacket 20 through which cooling water circulates, is formed on the sidewall of the cylinder 11.
- the water jacket 20 communicates with a radiator 21 consisting of thin-walled tubes and metal fins (not shown) .
- the water within the jacket 20 receives heat from the hot cylinder 11, thus cooling the cylinder 11 to a desired temperature while becoming hot water due to heat from the cylinder 11.
- the hot water thereafter, flows from the jacket 20 into the radiator 21.
- the hot water circulates within the thin-walled tubes and metal fins of the radiator 21 and dissipates heat into the atmospheric air.
- the air is forced to pass through the gaps between the fins of the radiator 21 by a cooling fan.
- the cylinder 11 also discharges high temperature exhaust gas into the atmosphere through a muffler (not shown) .
- an object of the present invention is to provide an apparatus for generating power using heat of both cooling water and exhaust gas of an internal combustion engine, which is designed to lead high temperature cooling water from the engine into a boiler and to heat the water using heat of exhaust gas from the engine, thus primarily generating highly pressurized hot steam within the boiler and secondarily operating a turbine using the steam to generate power usable as a power source for additional drive parts, and which thereby improves the thermal efficiency of the engine, conserves fuel, and effectively protects the environment from the exhaust gas.
- the present invention provides an apparatus for generating power using heat of both cooling water and exhaust gas of internal combustion engines, comprising: an internal combustion engine of the two cycle- or four cycle-type; a heating means connected to the engine and used for heating high temperature cooling water, discharged from the engine, using heat of exhaust gas of the engine, thus generating highly pressurized steam; a turbine operated using the steam of the heating means; a water feedback pipe extending from the turbine to a water jacket of the engine and feeding condensed water from the turbine back to the water jacket; a water circulation pump mounted on the water feedback pipe to pump the condensed water flowing in the water feedback pipe; and a check valve mounted on the water feedback pipe to prevent a reverse flow of the condensed water within the pipe.
- the heating means comprises: a boiler connected to the engine through a cooling water discharge pipe, thus receiving the high temperature cooling water discharged from the engine; an exhaust gas pipe extending from a cylinder of the engine into the boiler, thus leading the exhaust gas of the cylinder into the boiler; a heating pipe extending from the exhaust gas pipe and thoroughly passing through the boiler, thus heating the cooling water within the boiler using the heat of the exhaust gas; and a steam tank installed on the boiler while communicating with the boiler to temporarily store the steam discharged from the boiler prior to feeding the steam to the turbine.
