Abstract
The utility model discloses a novel six-cylinder gasoline engine cylinder cover which can achieve high volumetric efficiency required by an existing engine. The technical key is that the novel six-cylinder gasoline engine cylinder cover comprises a group of combustion chambers located at the bottom of a cylinder cover and a group of air inlet channels corresponding to the combustion chambers and located on the side faces of cylinders, wherein the air inlet channels are connected with two air inlet valves, the air inlet valves are connected with exhaust channels through two exhaust valves, drive mechanisms of the air valves are double overhead cams, the two air inlet valves and larynx aperture regions of valve seats of two rows of air valves are provided with spark plugs, and an air valve lifter arranging region connected with the air valves is further arranged in the middle of the cylinder cover.
Description
Technical field
The utility model relates to the automobile engine assembly system, is specifically related to a kind of cylinder head of six cylinder gasoline engines.
Background technique
Be able in automotive engineering today that fast development and people's material life improve day by day, people's the car idea of purchasing begins to change, be satisfied with no longer originally that inexpensive matter is poor can open to get moving scooter just, begin to pursue high-quality, high-performance, high-comfort luxurious car.People have proposed higher harsher requirement to the performance of car, especially to power assembly system, when requiring motor to have higher power character and acceleration, reduce to greatest extent fuel consume and discharge amount.Growing along with Computer-aided Design Technology and automated control technology, the high-end Three-dimensional Design Software of CAS/CAD/CAM/CAE is widely applied the Automobile Design field, it is more and more quick that the exploitation of automobile new product becomes, it is more and more ripe that the development technique of motor and development tool also become, various motorcar engine power per liter obviously improve, gone up by initial HP, hp/litre 30KW/ and be raised to the liter near 60KW/, motor begins to the development of small displacement high power.
At present, it is all from two aspects that the engine performance main path gets on to improve at available engine art platform in numerous producers, goes to change the intrinsic internal structure of motor by optimal design on the one hand, improves the motor charging efficiency, thereby improves engine power; By grasping the moving law of motor, increase some special devices on the other hand, carry out real-time external control by engine control system, thereby improve engine power and moment of torsion.Wherein optimizing on structure to improve internally has: 1) increase the valve number; 2) optimize engine chamber and intake duct shape; 3) change the bore and stroke ratio; 4) improve engine compression ratio, increase mean effective pressure; 5) application of multiple advanced material.Carrying out real-time external control by engine control system on the other hand, to go to improve the means of engine power more, because shadow noon, the factor that improves of engine power had a lot, different operating modes, different rotating speeds, the effect such as different valve opening angles and different air inlet-outlet pipe length lower cylinder charging efficiency is all different, and the power that motor produces is also different.Control in addition the fuel injection quantity of each operating mode the best, the spark plug of controlling the firing angle of each operating mode the best and selecting maximum ignition energy is sizable to the performance shadow noon of motor.
Yet the present domestic engine development state of the art is that most of automobile vendor spends high technical fee from buying a existing engine technology drawing and technical documentation abroad, manufactures.In case and product technology occurs again barren when updating.
The model utility content
Technical problem to be solved in the utility model is, for the structural technical deficiency of available engine, particularly engine air cylinder head structure is aging, can't satisfy the requirement to the required higher charging efficiency of motor, domestic existing air cylinder head structure is improved to solve the deficiencies in the prior art.
Such in order to address the above problem the technical solution of the utility model:
A kind of novel six cylinder gasoline engine cylinder head, comprise one group of firing chamber and one group of intake duct of being positioned at cylinder side corresponding with the firing chamber that is positioned at the cylinder cap bottom, described intake duct connects two intake valves, and described intake valve connects air outlet flue by two exhaust valves again.
The driving mechanism of described intake valve and exhaust valve is that crest places the cam drives; The aditus laryngis region division of the gate seat of described two intake valves and two exhaust valves has spark plug; The middle part of described cylinder head also is provided with valve tappet and arranges that the district is connected with exhaust valve with each intake valve.
Beneficial effect, this six cylinder gasoline engine cylinder head have reached the required higher charging efficiency of available engine.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of novel six cylinder gasoline engine cylinder head described in the utility model;
Wherein, 1 is the firing chamber, and 2 is spark plug, and 3 is air outlet flue, and 4 is suction valve cone, and 5 is exhaust valve seat.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, this six cylinder gasoline engine cylinder head comprise one group of firing chamber 1 and one group of intake duct of being positioned at cylinder side corresponding with the firing chamber of being positioned at the cylinder cap bottom, described intake duct connects two intake valves, intake valve connects air outlet flue 3 by two exhaust valves again, the suction valve cone 4 of intake valve and the exhaust valve seat 5 of exhaust valve all are positioned on the sidewall of cylinder head, and the aditus laryngis place of suction valve cone 4 and exhaust valve seat 5 is spark plug 2.
This engine cylinder cap becomes four valves by two original valves, is respectively two intake valves and two exhaust valves, is convenient to like this increase the time face amount of valve, is beneficial to the increase air inflow.The driving mechanism of valve uses crest places the cam to drive, and has saved bulk zone.The cylinder middle part is provided with the valve tappet that is connected with valve and arranges the district, and driving mechanism is simplified, and guarantees simultaneously high speed reliability stability.
Above demonstration and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
