Abstract
The invention relates to a waste gas energy air compressor which is a machine for generating compressed air by utilizing energy of waste gas exhausted from an internal combustion engine. The waste gas energy air compressor comprises three major parts of a turbine air pump main body, an oil cooler and an air storage tank. A turbine and a turbine shaft are assembled by tight fit for forming a high-speed rotating body in the turbine air pump main body, and the turbine shaft firstly penetrates an oil cooling cavity for cooling and then is connected with a high-speed end of a star-shaped speed reducer; and a low-speed end of the star-shaped speed reducer is connected with an air pump by using a connector. High-temperature oil in the oil cooling cavity is sent to the oil cooler for cooling by penetrating a housing through an oil pipe and then returned to the oil cooling cavity for recycling. High-pressure air generated by the air pump in the turbine air pump main body is sent to the air storage tank for storage through a high-pressure air delivery pipe. The waste gas energy air compressor provides a new mode for boosting the waste gas; compared with the turbine boosting mode, the role of increasing the power of the internal combustion engine is more significant, and the utilization of the energy of the waste gas is maximized.
Description
Affiliated technical field
A kind of exhaust energy of discharging with internal-combustion engine that the present invention relates to produces compressed-air actuated machine, for the waste gas supercharging provides a brand-new pattern.Make the castering action of power of IC engine more remarkable, the utilization of waste gas energy also maximizes.
Background technique
According to one's analysis: the 25%--40% energy is drained with the waste gas form by internal-combustion engine after the oil inflame.At present, engine exhaust gas can just be used for to the air inlet supercharging, and promptly so-called turbosupercharging can improve about 25% internal-combustion engine output power.But turbosupercharging is because self structure, the defective that exists some to overcome:
1, turbo charged driving turbine and driven centrifugal blower are coaxial integral machines, and structure is very compact.Suction tude and outlet pipe all will be connected on the integral machine, yet the relief opening of internal-combustion engine and suction port all are distributed in the cylinder head both sides, make that suction tude and outlet pipe space layout are very difficult, because being subjected to have to " turn round and touch the angle " " trudging " and outlet pipe of all multifactor restrictions such as space, function, suction tude meets.Curved long air flue strengthens the air inlet vapour lock, has hindered the lifting of internal-combustion engine output power.
2, because the space is narrow and small, in the integral machine connection place, suction tude and outlet pipe almost are that " next to the shin " distributes.The high temperature of outlet pipe reduces the rising of suction tude intake temperature, density of the induced air, and the internal-combustion engine output power is descended.
3, turbo boost pressure is directly proportional with I. C. engine exhaust speed.When the big load of internal-combustion engine, low-speed running, the slow boost pressure of exhaust velocity is low, and is little to the effect of internal-combustion engine output work power ascension; And when the internal-combustion engine light load, when running up, the fast boost pressure height of exhaust velocity, quick-fried for preventing the too high initiation shake of suction pressure, bleed off part super charge to turn down pressure, cause the waste of waste gas energy.The statement of image is: it is not given when, and it is not given suddenly when wanting.
In sum: because the existence of turbosupercharging intrinsic defect, turbosupercharging is had a greatly reduced quality to the castering action of power of IC engine.
Summary of the invention
At turbo charged intrinsic defect, the present invention uses turbine through deceleration rear driving air pump earlier, and the high-pressure air that air pump produces send gas holder to store.High-pressure air in jar enters cylinder tonifying Qi supercharging through the high pressure blowdown pipe from cylinder head.So not only reach the effect of air intake pressurized, and make the castering action of power of IC engine more remarkable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of waste gas energy air compressor comprises: turbine air pump main body, oil cooler, gas holder three parts.Turbine air pump main body is assembled into by shell, turbine, turbine shaft, oily cooling chamber, star-like retarder, air pump.Turbine and turbine shaft are assembled into a high-speed rotary body with drive fit, and turbine shaft is equipped with bearing and Sealing with rotating body for supporting.The high velocity air that internal-combustion engine is discharged drives turbine and drives the turbine shaft high speed rotating, and the rotating speed of turbine shaft is several ten thousand revolutions per seconds, and the air pump rotating speed only needs several thousand revolutions per seconds, and the power of turbine shaft passes to air pump after must slowing down.Star-like retarder has compact structure, reduction speed ratio is big, efficient is high, the characteristics of output input shaft on a center line, can satisfy the incorporate requirement of the gentle pump structure of turbine of the present invention.Star-like retarder low speed end connects with air pump with joiner.
For the high temperature that prevents waste gas damages turbine shaft and bearing, turbine shaft connects with star-like retarder speed end after passing oily cooling chamber cooling earlier again.The high temperature oil of oil in the cooling chamber passed shell by oil pipe and delivered to and return oily cooling chamber after the oil cooler cooling and recycle.
The high-pressure air that air pump produces in the turbine air pump main body is delivered to gas holder through high pressure gas pipeline and is stored.
The invention has the beneficial effects as follows:
1, high-pressure air directly enters supercharge cylinders by blowdown pipe, does not have suction tude vapour lock problem.
2, outlet pipe only connects with waste gas energy air compressor, does not also exist suction tude to be heated problem.
The high-pressure air that produces when 3, internal-combustion engine runs up is stored by gas holder, supercharging when can be used for the internal-combustion engine low-speed running, the internal-combustion engine that makes section power ascension effect equilibrium at full speed.
4, since the internal-combustion engine long-term work at a high speed, the light load situation, sufficient high-pressure air not only can be used for supercharging, also can be used for other purposes as braking etc., can save other air compressor in case of necessity.
5, when waste gas energy air compressor is applied to " oil-gas " type " bimodulus environmentally friendly vehicle " internal-combustion engine, sufficient high-pressure air becomes second energy of automobile, realizes waste gas " zero-emission ".
