Abstract
The invention discloses a turbocharging system for an internal combustion engine, comprising the internal combustion engine which is provided with an evaporator capable of generating high-temperature and high-pressure water vapor on an exhaust pipe. The water vapor is guided into the turbine end of a supercharger by a pipeline to drive impellers of the turbo machine to rotate at a high speed and drive a coaxial air compressor to compress the air from an air filter, and the supercharged air is passed through an intake manifold of the internal combustion engine to enter the internal combustion engine. The water vapor discharged by the turbo machine is guided into a condenser that can condense the high-temperature and high-pressure water vapor into the water closed to the boiling point, and then is flowed back to the evaporator to circulate continuously. Because the water vapor is generated to drive the turbo machine and drive the coaxial air compressor to compress the air from the air filter, the exhaust back pressure can not be increased, and power of the internal combustion engine also can not be consumed. And an operating temperature is much lower, and a cooling requirement is lower, thereby compared with the exhaust turbocharging machine, the cost is reduced a lot; and the turbocharging system can be used together with the exhaust turbocharging machine.
Description
Technical field
The present invention relates to a kind of internal combustion engine turbocharging system, the turbo charged system that particularly a kind of water vapour that utilizes the I. C. engine exhaust waste-gas heat to produce drives.
Background technique
Automobile has become the widely used traffic tool, and existing automobile uses internal-combustion engine to be used as power basically, and the our times various countries have all dropped into great amount of manpower and material resources and financial resources, and how research reduces the discharging and the fuel consumption of internal-combustion engine.But from present technical standpoint, although the invention of internal-combustion engine has the history in more than 100 year, still have only 40% but its fuel availability is the highest, meanwhile about 40% fuel energy enters atmosphere in modes such as heat energy from outlet pipe in addition, so not only cause a large amount of wastes of fuel, but also bring a large amount of exhaust pollutions, increased Global Greenhouse Effect.So people drop into very big effort aspect the research of I. C. engine exhaust heat energy utilization, be deflated the energy of taking away in the hope of reclaiming internal-combustion engine.Utilize the prior art of car combustion engine exhaust energy to have: exhaust gas turbocharge and lithium bromide refrigeration heat, utilize I. C. engine exhaust heat energy to give automobile heating, preparation hot water and generating etc. in addition in addition.The exhaust gas turbocharge meeting increases the exhaust back pressure of internal-combustion engine; The lithium bromide refrigeration heat is on internal-combustion engine, because it is very harsh to the requirement of factors such as mechanical vibration, and can't be applied on the vehicle of exercising; Utilize the exhausting heat energy heating also only to be used on the automobile of air cooling engine; Utilize its preparation hot water only to be applicable to military trucks, large-scale haulage vehicle, and value is not high yet; Utilize the exhausting heat energy generating, mechanism's complexity, use equipment is many, the cost height, using value is not high yet.
At present, widely used supercharging of internal combustion engine technology has engine driven supercharging and exhaust gas turbocharge.Though mechanical supercharger does not increase the engine exhaust back pressure, need the power of consumption of engine, and boost pressure is generally lower.The exhaust gas turbocharge meeting increases the exhaust back pressure of motor greatly, and will pass through high-temp waste gas in the pressurized machine, and the parts of turbo machine all need to use resistant to elevated temperatures material, the design accuracy height of turbo machine, complex process.The operating conditions of bearing is abominable, damages easily, requires very high to lubricated and cooling.For the pressurized machine in variable-nozzle cross section, the also exigent precision of this changeable mechanism, cost height.
Summary of the invention
The purpose of this invention is to provide a kind of internal combustion engine turbocharging system, this pressurization system is converted into the kinetic energy of water vapor with exhausting heat energy, utilizes the kinetic energy of water vapor to drive pressurized machine, increases suction pressure.And can not increase exhaust back pressure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion engine turbocharging system, comprise internal-combustion engine, the vaporizer that can produce high-temperature high-pressure steam is installed on the outlet pipe of internal-combustion engine, the water vapor of the High Temperature High Pressure of generation is imported the turbine end of pressurized machine by pipeline, water vapor drives the turbine wheel high speed rotating, the impeller that drives coaxial gas compressor rotates with speed, compression is from the air of air-strainer, and the air of process supercharging enters internal-combustion engine by inlet manifold of IC engine again.The water vapour of discharging from turbo machine imports to and makes high-temperature high-pressure steam be condensed into coagulator near the water of boiling point, is back to vaporizer again, constantly circulation.
Described pressurized machine can adopt various changeable mechanisms to control boost pressure equally, or the method that adopts the simpler turbo machine air inlet of structure to dam changes boost pressure.
Good effect of the present invention is, produce the turbine end that water vapor imports pressurized machine owing to adopt, water vapor drives the turbine wheel high speed rotating, the impeller that drives coaxial gas compressor rotates with speed, and compression is from the air of air-strainer, and pressurized machine is similar with existing exhaust-gas turbocharger structure and principle, but this pressurized machine does not directly utilize exhaust gas driven, only utilize the heat energy of waste gas, therefore can not increase exhaust back pressure, also do not consume the power of internal-combustion engine.The steam temperature that drives turbine is more much lower than exhaust gas temperature, and the controlling mechanism in the parts of turbo machine and bearing and variable-nozzle cross section need not to use exotic material, does not also need very high precision.The also available aluminium alloy casting of volute, weight reduction.The impeller of turbo machine also can be used the aluminum alloy material identical with compressor impeller, and is in light weight, and response is fast, accelerates the responsiveness of pressurized machine.Require also lower to cooling.Cost reduces a lot than turbosupercharger.
For gasoline engine, because row's temperature is higher, and the supercharging level that needs is not high, relatively is fit to use this pressurization system.Also do not reclaim a part of exhausting heat energy on the basis of consumption of engine power not increasing exhaust back pressure.And for diesel engine, because row temperature is relatively low, and supercharging level has relatively high expectations, and is fit to use the combined supercharging of this pressurization system and exhaust gas turbocharge combination, no longer increasing a basic enterprising recovery exhausting heat energy of exhaust back pressure.
Below in conjunction with drawings and Examples the utility model is further described.
