Description

System for generating hydrogen and oxygen, for fuel and emission reduction of an internal combustion engine; vehicle; and retrofit kit.
Description
The invention relates to a system for generating hydrogen and oxygen for supply to the air intake of an internal combustion engine, preferably of a vehicle, comprising an electrolytic cell for generating said hydrogen and oxygen gas by electrolysis of an electrolyte such as a solution of salt in demineralized water, the electrolytic cell comprising an anode and a cathode and being configured to be powered from an electrical power source, and a gas output port for feeding hydrogen gas and oxygen gas to the air intake of the engine, the system further comprising a cooling unit for cooling the electrolyte which is present in the cell in use, the cooling unit comprising a heat exchanger and a circulation pump, which are connected to an electrolyte inlet port and an electrolyte outlet port of the electrolytic cell such that using the pump a circulation of electrolyte is provided from the electrolytic cell, via the electrolyte outlet port, through the heat exchanger, and via the electrolyte inlet port back into the electrolytic cell in use.
The invention further relates to a vehicle comprising such a system. The invention also relates to a retrofit kit for connection thereof to the air intake of an internal combustion engine.
WO 2007/133174 discloses a hydrogen generator. The generator includes a electrolytic reactor for generation of hydrogen and oxygen gas for supply thereof to a combustion chamber of an internal combustion engine. The system comprises a cooling system for cooling the reactor. The cooling system comprises a pump and a liquid-air heat exchanger for cooling electrolyte by circulating it through the heat exchanger in the form of a radiator. The radiator is arranged for exchanging heat between air and the electrolyte which is pumped through the radiator.
An object of the invention is to provide a system for generating hydrogen and oxygen, having an improved cooling system.
The object is achieved by the system according the invention, which is characterized in that the system comprises a control system for actuating the circulation pump, and in that the heat exchanger is of the plate type wherein in use heat is exchanged between the electrolyte and liquid coolant, the heat exchanger being at least substantially made of a corrosion resistant material, wherein the cooling unit further comprises a radiator and a second circulation pump, which are connected to the plate type heat exchanger such that using the second pump liquid coolant is circulated from the plate type heat exchanger, through the radiator and back into the plate type heat exchanger in use.
The corrosion resistant material is preferably a corrosion resistant alloy such as stainless steel, titanium, or Hastelloy.
In the system according to the invention electrolyte circulates through an at least substantially corrosion resistant, preferably stainless steel, plate type liquid-liquid heat exchanger. This type of heat exchanger is relatively cost efficient compared to a stainless steel radiator. Thus, according to the invention a two-step cooling system is provided wherein the electrolyte is circulated through a corrosion resistant plate type heat exchanger and, for example, standard coolant is used for cooling the electrolyte by circulating it through the heat exchanger. The coolant is in turn circulated through a standard (liquid-air) radiator so as to exchange heat with the air. Although the number of components may be increased, still an important cost reduction can be achieved because the environmentally aggressive electrolyte is now cooled in a more cost efficient manner wherein an expensive stainless steel radiator is not required any more.
With a system according to the invention a decrease in fuel consumption of over 35% can be achieved, for petrol as well as diesel. Soot emissions can be decreased for 80% and carbon dioxide emissions can almost completely be cancelled.
Preferably ethylene glycol is added to the coolant.
In an embodiment the control system is connected to a temperature sensor which is in fluid contact with the electrolyte, wherein the control system is configured to actuate the pump in response to a difference between a predetermined target system temperature and the temperature as measured by the temperature sensor. This way the temperature of the electrolyte can be kept at an optimal, predetermined level. The pump can be actuated on/off, or alternatively or in combination therewith, at a variable speed, dependent on the required cooling capacity.
It is advantageous if the control system is configured to switch on the electrolytic cell when the engine is running and to shut off the electrolytic cell when the engine is not running. This means that in use the system only generates hydrogen and oxygen gas when the engine is running, i.e. when there is a demand for said gases. In the system according to the invention there is therefore no need to store any produced gases. This increases the safety of the system considerably.
In a simple yet effective embodiment the gases are transported from the electrolytic cell to the engine air intake via a single, direct conduit.
Preferably the electrolytic cell comprises a further electrolyte inlet port for supplying electrolyte to the electrolytic cell, for example from an external reservoir in the vehicle.
Preferably the electrolyte inlet port and the further electrolyte inlet port are formed by one single inlet port. In this case electrolyte may be fed to the electrolytic cell via a supply inlet which is connected to the conduits of the electrolyte cooling unit, for example in a conduit connecting the heat exchanger to the cell.
The invention further relates to a vehicle comprising an internal combustion engine, the above described system according to the invention for generating hydrogen gas and oxygen gas, the gas output port of the system being connected to the air intake of the engine, the vehicle further comprising a battery for powering the electrolytic cell in use.
The invention also relates to a retrofit kit for connection thereof to the air intake of an internal combustion engine, preferably of a vehicle, the retrofit kit comprising the electrolytic cell, the circulation pump and the heat exchanger according to the present invention, wherein the heat exchanger is configured to be connected to a separate radiator and to a second circulation pump such that using the second pump liquid coolant is circulated from the heat exchanger, through the radiator and back into the heat exchanger in use.
The present invention will now be explained in more detail by means of a description of a preferred embodiment of a system according to the present invention, in which reference is made to the following schematic figure, wherein
- Figure 1 shows a preferred embodiment of a system according to the invention.
Figure 1 shows a system 1 for generating hydrogen gas and oxygen gas for supply thereof to the air intake of an internal combustion engine, for example of a vehicle or as part of an industrial application (not shown). System 1 comprises an electrolytic cell 2 for generating said gases by electrolysis of an electrolyte such as a solution of salt in demineralized water. Electrolytic cell comprises an anode and a cathode and being configured to be powered from an electrical power source, for example being the vehicle battery. The electrolytic cell 2 has a first electrolyte inlet port 10 for supplying electrolyte to the inner space of the electrolytic cell 2, for example from an external reservoir, a gas output port 12 for feeding hydrogen gas and oxygen gas to the air intake of the engine, a second electrolyte inlet port 14, and an electrolyte outlet port 16. In case the engine is equipped with a turbocharger, the gas output port is connected to the air intake of the engine downstream of the turbocharger. The inner space of the electrolytic cell 2 is closed to such an extent that gases cannot escape other than via the gas output port 12 to the air intake of the engine.
The system further has a cooling unit 20 for cooling the electrolyte. Cooling unit 20 comprises a stainless steel plate-type liquid-liquid heat exchanger 22 and a circulation pump 24. Pump 24 is, with its inlet side, connected to the electrolyte outlet port 16 via conduit 26. Pump 24 is, with its outlet, or, pressure side connected to an inlet of a first flow path through the heat exchanger via conduit 28. Electrolyte can flow from conduit 28 through the heat exchanger, and via conduit 29, which connects the first flow path of the heat exchanger to the second electrolyte inlet port 14, back into the cell 2. Thus, using the pump 24 a circulation of electrolyte can be provided from the electrolytic cell 2, through the first flow path of the heat exchanger 22, and back into the electrolytic cell 2. The pump 24 is actuated by a control system (not shown). The control system actuates (drives) the pump 24 in dependence of the temperature of the electrolyte which is sensed by a temperature sensor. The pump is actuated in response to a difference between a predetermined target system temperature and the temperature as measured by the temperature sensor. In practice the pump starts running when the temperature rises above a lower boundary. By keeping the operating temperature at a fixed level, for example at 55 degrees Celcius, the efficiency of the electrolysis process is increased. The control system is further arranged to only switch on the electrolytic cell when the engine is running and to disable the electrolytic cell (by shutting off the power supply from the battery) when the engine is not running. This means that gases are only generated when there is a demand for said gases from the engine. Gases are not accumulated in the system which contributes to the safety of the system. The system also has a drain port (not drawn) for the purpose of refreshing the electrolyte in the electrolytic cell. The cooling unit 20 further comprises a radiator 30 and a second circulation pump 32. Pump 32 is with its inlet side connected to an inlet of a second flow path through heat exchanger 22 via conduit 34 and with its outlet side to the radiator 30 via conduit 36. The radiator is connected to the second flow path of the heat exchanger via conduit 38. Thus, using the pump 32 a circulation of coolant can be provided from the second flow path of heat exchanger 22, through the radiator 30 and back into the heat exchanger 22. Heat from the electrolyte is hence transferred to the coolant in the heat exchanger 22 and heat from the coolant is transferred to the outside air in the radiator. Optionally a fan 40 is mounted on the radiator to increase forced convection.
The above system can be supplied as a retrofit kit for connection thereof to the air intake of an internal combustion engine, for example of a vehicle. The retrofit kit comprises the electrolytic cell 2, the circulation pump 22 and the heat exchanger 22. The heat exchanger 22 is configured to be connected to a separate circulation pump 32 and radiator 30. I.e. in case of a vehicle, other than the vehicle radiator and/or coolant circulation pump, so that the cooling system of the engine is not influenced.
