Abstract
The invention relates to a cylinder cover used for an engine. The cylinder cover comprises an air inlet channel and an air outlet channel. A ventilation channel is arranged between the air inlet channel and the air outlet channel. The engine comprises the cylinder cover and a piston cylinder; the two sides of the piston cylinder are provided with the air inlet channel and the air outlet channel; the ventilation channel is arranged between the air inlet channel and the air outlet channel; and the air inlet channel communicates with the air outlet channel. When the engine works, the piston cylinder sucks fresh air through the air inlet channel and meanwhile sucks a small amount of waste gas in the air outlet channel through the ventilation channel, after the fresh air and the waste gas are mixed, the fresh air and the waste gas enter the piston cylinder together to participate in combustion, and therefore oxygen entering vortexes is reduced, generation of oxynitride is inhibited, and emission of waste gas is reduced; and the diameter of the ventilation channel is 3%-6% of the diameter of a cylinder body of the piston cylinder, so that the proportion of the mixed waste gas can be conveniently controlled, and the power performance of the engine is prevented from being affected.
Description
Technical field
The present invention relates to a kind of engine cylinder head and apply the electromotor of this cylinder head.
Background technology
Diesel engine be burning diesel oil to obtain exergonic electromotor, it has a wide range of applications in industrial and agricultural production.Expansion along with petrochemical industry fuel range, the discharge capacity of oxynitride is increasing, that how to reduce the waste gas such as oxynitride arranges into the key subjects faced for people, it is well known that the essential condition in oxynitride formation mechenism is exactly high temperature and oxygen-enriched.
Chinese Patent Application No. 201420502468.6 discloses a kind of cylinder head sub-assembly, it includes cylinder head body (i.e. cylinder head) (1), spiral inlet channel (2) and exhaust passage (3) it are provided with on described cylinder head body (1), described inlet channel (2) entrance section is trapezoidal, is provided with choked flow and takes (4) in described inlet channel (2).
This patent makes fuel oil angle more fully of burning improve the combustibility of diesel engine from strengthening intake swirl, decrease the discharge of waste gas (mainly oxynitride), equally from minimizing intake swirl, the content of oxygen is started with, the generation of suppression oxynitride, reduces waste gas discharge.
Summary of the invention
The technical problem to be solved is to provide a kind of electromotor that can effectively reduce the discharge of oxynitride, simple in construction, engine cylinder head with low cost and apply this cylinder head.
In order to solve the problems referred to above, the invention provides a kind of engine cylinder head, it includes inlet channel and exhaust passage；Gas-permeable channels it is provided with between inlet channel and exhaust passage.
Present invention also offers a kind of electromotor, described electromotor includes cylinder head, the both sides of described piston cylinder are provided with inlet channel and exhaust passage, gas-permeable channels it is provided with between inlet channel and exhaust passage, make to connect between inlet channel with exhaust passage, during electromotor work, piston cylinder sucks fresh air by inlet channel, suck a small amount of waste gas in exhaust passage by gas-permeable channels simultaneously, after both mixing, the common piston cylinder that enters participates in burning, thus reduce the oxygen in intake swirl, the generation of suppression oxynitride, reduce waste gas discharge.
Further, described inlet channel and exhaust passage are arranged twist, and described inlet channel entrance section is trapezoidal, is provided with choked flow and takes in described inlet channel, makes intake swirl higher.
Further, described gas-permeable channels is cylinder, the 3%～6% of the piston cylinder body diameter of a diameter of described electromotor of described gas-permeable channels, it is simple to control to be mixed into the ratio of waste gas, it is to avoid waste gas sucks too much, affects the power performance of electromotor.
The technique effect of the present invention: the electromotor of (1) present invention, relative to prior art, arranges gas-permeable channels between inlet channel and exhaust passage, a small amount of waste gas can be circulated utilization, effectively reduce the discharge of oxynitride；(2) by controlling the ratio of gas-permeable channels diameter and piston cylinder body diameter, can control to be mixed into the ratio of waste gas, it is to avoid waste gas sucks too much, affects the power performance of electromotor；(3) simple in construction, with low cost.
Accompanying drawing explanation
Below in conjunction with Figure of description, the present invention is described in further detail:
Fig. 1 is the cylinder head schematic diagram of prior art；
Fig. 2 is the schematic diagram of the cylinder head of inventive engine.
In figure: cylinder head 1, inlet channel 2, exhaust passage 3, choked flow tower 4, gas-permeable channels 5.
Detailed description of the invention
Embodiment 1
Such as Fig. 2, the electromotor of the present embodiment, including cylinder head 1 and piston cylinder, the both sides of piston cylinder are respectively arranged with spiral inlet channel and exhaust passage, inlet channel entrance section is trapezoidal, inlet channel and a diameter of 32mm of exhaust passage, be provided with choked flow and take 4 in inlet channel, it is 11mm that the height of 4 is taken in choked flow.
Gas-permeable channels 5 it is provided with between inlet channel 2 and exhaust passage 3, the 3% of the piston cylinder body diameter of a diameter of electromotor of gas-permeable channels 5 or 4% or 5% or 5.6%, during the work of this electromotor, piston cylinder sucks fresh air by inlet channel 2, by gas-permeable channels 5, a small amount of waste gas in exhaust passage 3 is sucked inlet channel 2 simultaneously, and both enter piston cylinder after completing mixing, burning is completed in piston cylinder, owing to being mixed into waste gas, oxygen content declines, and the generation of oxynitride reduces.The material such as CO2 etc. that in waste gas, specific heat capacity is higher simultaneously can absorb the heat that burning produces, and ignition temperature is risen inhibitory action.So two essential condition high temperature in oxynitride formation mechenism and oxygen-enriched destroyed, thus reduce its discharge.Under high load capacity operating mode, excess air coefficient is the least, burn the most sensitive to the change of oxygen concentration, a small amount of waste gas introduces and oxynitride can be made to have significantly reduction, after this electromotor increases gas-permeable channels, in the waste gas of discharge, oxynitride content drops to 1.15 ‰ from 1.32 ‰, declines about 13%.
The above, be only presently preferred embodiments of the present invention, is not the restriction that the present invention makees other form, and any those skilled in the art are changed possibly also with the technology contents of the disclosure above or are modified as the Equivalent embodiments of equivalent variations.But every without departing from technical solution of the present invention content, any simple modification, equivalent variations and remodeling above example made according to the technical spirit of the present invention, still fall within the protection domain of technical solution of the present invention.
