Abstract

An internal combustion engine secondary power generator has a body 14, which can be attached to an internal combustion engine in order for the engine exhaust gas to transfer energy to the engine coolant. The body is secured to the engine by exhaust gas intake control valve fitting 2 in order that the engine exhaust gas flows through the control valve fittings to the gas-to-liquid heat exchanger 7 and the gas-to-gas heat exchanger 8 and then out the exhaust gas control valve fittings 12 and 13. The body is also secured to the engine by the engine coolant intake control valve filling 1 and exiting control valve fitting 11 in order that working fluid can receive the heat transfer from the heat exchangers 7 and 8, and transmit it to the turbine 9, cool in the condenser 10, and return to the engine via the exiting control valve fitting 11.

Description

2362683 Internal Combustion Engine Secondary Power Generator This
invention relates to a water-cooled internal combustion engine secondary power generator.
Water-cooled internal combustion engines are well known. There are special types of water-cooled internal combustion engine such as diesel engines that use the engine shaft output power to supply motive power to an electricity generator. These engines produce motive power and then emit exhaust gases without making further use of the exhaust gases' potential energy or the exhaust gases'thermal energy is used for heating purposes. The use of hot combustion gases as primary power sources to generate hot vapour from a liquid in order to drive a turbine is also well known.
The emission of hot exhaust gases into the atmosphere or their use solely in heat production is wasteful and relatively expensive. Moreover there is potential to use the energy of the hot exhaust gases for other purposes as well as heating, such as for applying energy to the internal combustion engine coolant in order to use the coolant as the working fluid in a turbine with which to generate secondary electric power.
According to the present invention there is provided an internal combustion engine secondary power producer comprising a body in the form of a box, a gas to liquid heat exchanger, means for admitting the engine coolant to the gas to liquid heat exchanger, connective adiabatic piping, a gas to vapour heat exchanger, a turbine, a condenser, and means for emitting the coolant. The body is adapted to allow the apparatus to be attached to and detached from a water-cooled internal combustion engine as well as an electricity generator.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in which:- Figure 1 shows a flow diagram of the system inside a box Referring to the diagram the system box 14 comprises an adiabatic coolant intake pipe 1, control valve 1, control valve 2, an adiabatic intake pipe 2 from the internal combustion engine exhaust along with an air to liquid heat exchanger 7, a gas to vapour heat exchanger 8, a turbine 9 with attachments, and a condenser 10. This includes the adiabatic piping 11 to return the coolant to the engine and the adiabatic piping 12 and 13 to emit the exhaust output from the heat exchangers 7 and 8 via control valves 12 and 13.
In order to transfer the maximum energy from the hot exhaust gases to the hot liquid coolant and the subsequently vaporized coolant, the hot exhaust gas mass is divided proportionately by the control valve 2. Control valve 2 then allows the hot exhaust gases to travel down adiabatic pipe 4 in the direction of arrow 4 and down adiabatic pipe 5 in the direction of arrow 5. The mean to transfer the energy of the hot exhaust gas travelling down pipe 4 to the hot liquid coolant emitted from the engine block is via the gas to liquid heat exchanger 7. The means to transfer the energy of the hot exhaust gas travelling down pipe 5 in the direction of arrow 5 to the vaporized coolant exiting from the gas to liquid heat exchanger 7 is via the gas to vapour heat exchanger 8.
In order to generate electricity from the superheated steam that is exiting from the gas to vapour heat exchanger 8, the superheated steam must pass through the turbine 9. The turbine has attachments that allow it to be connected to an electricity generator.
In order to return the cooled expanded steam to the engine coolant flow the cooled expanded steam must pass through the condenser 10. Control valve 11 allows the return of the working fluid to the engine coolant system in the direction of arrow 11.
In order to use the potential thermal energy in the warm fluids exiting the condenser 10 and the adiabatic exhaust gas piping 12 and 13, as a heat source as in a normal combined heat and power system, the condenser 10 and the gas exhaust pipes 12 and 13 can have adaptations to them. These adaptations include heat exchangers placed at the condenser location 9 and at the exhaust gas valve locations 12 and 13.
In order to maximise the heat transfers made in the above processes the piping between the components, including the gas to liquid heat exchanger 7, the gas to gas heat exchanger 8, the turbine 9, and the condenser 10, and the control valves is all adiabatic.
To dismantle the system from the internal combustion engine the connections at valves 2, 6, 11, 12, and 13 are unmade and the internal combustion engine is returned to its original state.
