Abstract

The invention relates to a method for using a tail gas of an engine, which consists of an impeller inertial wheel, a sheel sleeve, an exhaust tube and an air inlet tube and the like. The special point is that after the tail gas of the engine is combusted secondarily, carrying spoon impellers on the inertial wheel are sequentially worked according to the exhausted pressure so as to assist the engine in working without affecting discharge of the tail gas of the engine. The conversion efficiency is high, the method is simple, the maintenance cost can be greatly reduced, the using cost is reduced, and the engine can be used to make a novel efficient engine or a part of an old engine. Therefore, the method is wide in using prospect and has a remarkable energy-saving effect.

Description

A kind of motor exhaust utilize method

Affiliated technical field

Belong to the engine technology class, particularly a kind of motor exhaust utilizes method.

Background technique

Existing piston internal-combustion engine waste gas utilization technology is a lot, but mostly not bery ripe and do not have large size to popularize, what its application was the most ripe at most is turbocharging technology, but it is not directly to utilize tail gas to do work, but indirectly be used for improving the acting ability of engine combustion efficiency and motor, and its user cost is very high, and motor need to reach its effect of competence exertion behind the fixed wheel number, the invention provides and a kind ofly can directly utilize motor exhaust to do work, and be not subjected to the impact of engine revolution, same efficiently performance tail gas acting ability when slow speed, and also added simultaneously the secondary combustion system, make unburnt fuel obtain secondary and burn fully, the combustion efficiency that has namely improved motor has reduced again the tail gas pollution discharging.

Summary of the invention

In order to achieve the above object, the technological scheme that the present invention takes is improved the flying wheel on the single-cylinder engine, most peripheral intermediate portion with flying wheel, inwardly make uniformly the space of a week carrying spoonful shape on the arm, its opening is in the periphery intermediate portion of flying wheel, its opening becomes tangential direction with the flying wheel outside, carry a spoonful shape impeller on the arm at the inner circle that forms of the periphery of flying wheel like this, the corresponding casing that keeps relative closure with its opening that is provided with above its opening, one side at casing links to each other with the relief opening of motor, and another side is provided with the relative closure district successively, the smoke evacuation district, smoke-collecting area, smoke exhaust port; The former flying wheel place that flying wheel and the casing of above making is installed in respectively motor, and be sleeved on the outmost turns of flying wheel, and keep corresponding position with flying wheel, and casing is fixed on relief opening and other positions of motor; Its working procedure is to enter through outlet pipe from the gas that engine exhaust port is discharged to carry a spoonful shape impeller on the arm, through to carrying on the arm after spoonful shape impeller impacts acting, with the rotation of flying wheel, enter relative closure district, smoke evacuation district, smoke-collecting area that impeller and casing form, discharge finally by smoke exhaust port; The gas that motor is discharged will produce powerful impact force and workmanship to impeller when entering impeller, while is along with the rotation of impeller type flying wheel, the gas that motor is discharged will will be carried successively spoonful space of shape impeller on the arm according to the size of Exhaust Gas pressure and be filled, and along with the rotation of flying wheel flows to successively the relative closure district, smoke evacuation district, the smoke-collecting area that form between impeller and the casing, discharges finally by smoke exhaust port; Carry the opposite direction ejection that gas in the spoon can be rapidly rotates along flying wheel on the arm and form a reaction force to impeller again to the impeller acting when gas flows to when district smoke evacuation, discharge after the flue gas after the acting is assembled; In order to prevent that the heat on the impeller from conducting to the central shaft position of flying wheel, is provided with binding dish and heat insulating mattress between impeller and central shaft; For motor exhaust is fully burnt, the unidirectional air inlet pipe straight-through with outside air is installed between the bosom position of engine exhaust pipe 1 and engine exhaust port, the powerful negative pressure that unidirectional air inlet pipe forms around suction tude at the flue gas that outlet pipe 1 inner high speed flows when the engine exhaust is with the air intake of outside and carry out doing work after the mixed combustion.

Beneficial effect

Reciprocating engine can utilize tail gas to do work when not affecting its power after using this product fully, and efficiency of utilization is greatly improved, and is not subjected to the impact of engine revolution, and fabrication and installation are simple, and the working service cost is low.
