Abstract
The utility model discloses a kind of motor car engine cylinder end, comprise the cylinder head body (2) of band firing chamber (1), the outer wall of cylinder head body (2) is provided with radiating fin (3), it is characterized in that: on described cylinder head body (2), be provided with camshaft hole A(4) and camshaft hole B(5), described camshaft hole A(4) and camshaft hole B(5) for be arrangeding in parallel.The utility model has smart structural design, installs advantage easy to process, adopts it can improve the power of motor, reaches the stability and efficiency that improve cylinder head distribution device.
Description
Technical field
The utility model relates to a kind of motorcycle engine, particularly a kind of motor car engine cylinder end.
Background technique
The single cylinder Four valve cylinder head of existing motorcycle engine, mainly comprises cylinder head body, body is provided with single overhead cam, adopt single row configuration simultaneously, utilizes rocking arm to drive valve.Such structure influence intake and exhaust efficiency of motor, causes engine power to reduce, meanwhile, also makes the mechanical efficiency of engine valve actuating mechanism have certain loss.
Model utility content
The purpose of this utility model is just to provide a kind of motor car engine cylinder end that can improve engine power.
The purpose of this utility model is realized by such technological scheme, a kind of motor car engine cylinder end, comprise the cylinder head body of band firing chamber, the outer wall of cylinder head body is provided with radiating fin, described cylinder head body is provided with camshaft hole A and camshaft hole B, and described camshaft hole A and camshaft hole B is for be arrangeding in parallel.
Further, the camshaft A of band timing driven gear wheel A and the camshaft B of band timing driven gear wheel B is respectively arranged with in described camshaft hole A and camshaft hole B, on described cylinder head body and between camshaft A and camshaft B, be provided with the gear mandrel of band driving gear, described driving gear is taken turns A and timing driven gear respectively and is taken turns B and engage with timing driven gear.
In order to improve exhaust efficiency, described cylinder head body is provided with the double pore identical with firing chamber, described double pore is positioned at below camshaft A.
In order to improve heat dispersion, described radiating fin is provided with the vent hole running through radiating fin.
Owing to have employed technique scheme, the utility model has smart structural design, installs advantage easy to process, adopts it can improve the power of motor, reaches the stability and efficiency that improve cylinder head distribution device.
Accompanying drawing explanation
Accompanying drawing of the present utility model is described as follows:
Fig. 1 is cylinder head structure schematic diagram of the present utility model;
Fig. 2 is cylinder head structure stereogram of the present utility model;
Fig. 3 is the structural representation of strap cam axle of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any improvement or alternative on the present embodiment essence spirit, still belongs to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, a kind of motor car engine cylinder end, comprise the cylinder head body 2 of band firing chamber 1, the outer wall of cylinder head body 2 is provided with radiating fin 3, described cylinder head body 2 is provided with camshaft hole A4 and camshaft hole B5, and described camshaft hole A4 and camshaft hole B5 is for be arrangeding in parallel.
Further, the camshaft A7 of band timing driven gear wheel A6 and the camshaft B9 of band timing driven gear wheel B8 is respectively arranged with in described camshaft hole A4 and camshaft hole B5, on described cylinder head body 2 and between camshaft A7 and camshaft B9, be provided with the gear mandrel 11 of band driving gear 10, described driving gear 10 is taken turns A6 and timing driven gear respectively and is taken turns B8 and engage with timing driven gear.By the structure of twin cam shaft, make cam directly act on valve, thus reduce mechanical loss and keep transmission validity.
Further, described cylinder head body 2 is provided with the double pore 12 identical with firing chamber 1, described double pore 12 is positioned at below camshaft A7.By double pore 12, do the efficiency that not only can improve exhaust like this, but also stability and the efficiency of cylinder head distribution device can be improved.
Further, described radiating fin 3 is provided with the vent hole 13 running through radiating fin 3, is dispelled the heat by vent hole 13, the heat dispersion of cylinder head can be improved.
