Definitions
- the present invention relates to a new combined cycle explosion engine, which based on the basic structuring of a gasoline engine (Otto cycle) or diesel engine (diesel cycle) focuses its characteristics on the fact of that the thermodynamic cycle, which is governed in both cases, is modified by the contribution of a gas, specifically carbon dioxide (CO2), which, when in contact with hot combustion gases, experiences a strong thermal expansion, contributing thus to significantly increase the pressure inside the cylinder.
- a gas specifically carbon dioxide (CO2)
- the regulation of the engine can be carried out in two ways, one regulating the entry of air and fuel that burns inside the engine cylinders, as is currently the case in a conventional engine, and the other by dosing or modifying the amount of carbon dioxide supplied to the cylinder
- the object of the invention is to achieve a combined cycle engine, from the thermodynamic point of view, in which the energy given off in combustion is better used in terms of its conversion in a useful mechanical work, precisely because of the combination of two different thermodynamic cycles, but with the special feature that, by mixing the gases that participate in it, a degree of mechanical complexity for the engine is achieved considerably less than that of the combined cycle engines in which the gases act without mixing.
- the engine that the invention proposes is especially suitable for use in the automotive field.
- thermodynamic engines are known, based on the combination of two different thermodynamic cycles, such as one of gas and another of steam, which results in a final flue gas temperature, that is, at the end of the thermodynamic process, considerably lower, which means that the thermal energy that is transferred to the environment has a lower temperature level.
- these combined cycle explosion engines are designed to recover water vapor, so that it can cool and condense for reuse, which brings extraordinary mechanical complexity to the engine, which requires independent means for treatment of gases, which not only affects costs but also makes these combined cycle engines cannot be applied to the automobile field, for which the engine of the invention has been fundamentally conceived, both for reasons of space and of weight.
- the combined cycle engine that the invention proposes solves in a fully satisfactory manner the problem set forth above.
- a carbon dioxide (CO2) power supply consisting of a tank of appropriate capacity, where said carbon dioxide (CO2) can be in liquid or gas phase, in depending on the environmental conditions, said tank being properly connected to the engine cylinders, to which carbon dioxide (CO2) is accessed through injectors designed for that purpose, either with the same pressure with which said gas is in the tank or at a higher pressure with the collaboration of an appropriate pump, carbon dioxide (CO2) being introduced into each cylinder immediately after the piston has exceeded the top dead center, to avoid pressure overload inside the cylinder and also to allow time for combustion of the injected fuel, such as gasoline or diesel fuel, to take place so that when entering ntacto carbon dioxide (CO2) with combustion gases, at high temperature, there is a heating of said carbon dioxide (CO2) which causes an expansion thereof with the consequent increase in pressure inside the cylinder and, at
- carbon dioxide (CO2) is injected into the periphery of the cylinder, thereby achieving a double effect: on the one hand, it does not interfere excessively with combustion gases and on the other, and this is essential, to establish a thermal insulation barrier between the mass of hot gases inside the cylinder and the wall of the cylinder, which prevents heat leakage and improves engine performance.
- the turbulence within the ⁇ ' The cylinder guarantees at all times the gradual and progressive heating of carbon dioxide (CO2) and the transfer of heat between hot gases and the coldest gas (CO2) that is injected into the cylinders.
- the contribution of gas to the cylinders implies an increase in engine power.
- This increase in power can be regulated by reducing the amount of fuel in order not to exceed the limit power demanded at all times.
- a reduction of the fuel consumption of the engine can be achieved more than remarkable for two reasons: One of them because the mere contribution of gas (CO2) to each of the engine cylinders already implies in itself an increase in pressure within them, and another because the strong expansion experienced by the injected carbon dioxide (CO2) further enhances the pressure increase.
- CO2 carbon dioxide
- This gas which has to be separated from petroleum and methane which is the main component of natural gas, can be channeled and transported, duly liquefied, to the corresponding distribution centers, to finally be used in explosion engines such as the invention, achieving the double advantage of decreasing energy consumption and at the same time reducing atmospheric pollution derived from the combustion of some petroleum derivatives such as diesel and gasoline.
- Figure 1 shows a basic schematic representation of an installation of liquefied carbon dioxide (CO2) for feeding a combined cycle explosion engine made in accordance with the object of the present invention, in its specific application to a motor vehicle.
- CO2 liquefied carbon dioxide
- Figure 2. Shows a diagram of the engine duty cycle of the previous figure.
- the heat exchanger (5) uses as inherent thermal energy the combustion gases produced by the engine itself (6), so that said exchanger (5) is in turn embedded in the exhaust pipe (9) which, coming from the exhaust manifold (10), it evacuates combustion gases to the outside through its terminal outlet (11), after passing through the classic silencer (12).
- the safety valve (3) will be assisted by a conduit (13) also communicated with the exhaust pipe (9).
- the work area (17) due to the incorporation of carbon dioxide (CO2) is a continuation or extension of the work area (16) carried out by flue gases, evidencing furthermore said figure that the invention allows, for the same engine power, a marked decrease in fuel consumption, or a sharp increase in engine power, without increasing fuel consumption and without increasing the engine limit temperature, at part of the heat of the combustion gases is absorbed by carbon dioxide (CO2) during its expansion phase.
- CO2 carbon dioxide
- CO2 carbon dioxide
- Soot production is significantly reduced due to the lack of oxygen for the combustion of diesel oil burning inside the engine, since less fuel is burned and burned in better conditions, with the same amount of air in the case of the diesel engine, Soot formation is reduced and. the lubricating oil is less dirty allowing space 'more oil changes.
