Abstract
The utility model provides a cylinder head for a petrol engine, which relates to the improvement of an engine component, particularly an improved cylinder head for the petrol engine. The utility model has the proposal for solving the technical problem that the cylinder head for the petrol engine comprises a basal body (1) of the cylinder head and an E-shaped iron cast piece (2) cast together with the basal body (1) of the cylinder head, wherein three cylinders of the E-shaped iron cast piece (2) are provided with two bolt holes (21), (22) for installing a valve rocker assembly. Via the technical scheme, the utility model can largely reduce gap variation quantity generated by thermal expansion between a valve rocker and a top rod when the engine is started up with a cold engine and works with heat engine, so that noise generated by the increased gap because of the thermal expansion can be reduced.
Description
Technical field
The utility model relates to the improvement to engine components, relates in particular to a kind of improved petrol engine cylinder head.
Background technique
In the prior art, motorcycle engine both can produce very big noise usually when startup and proper functioning, influence people's live and work; Can produce a lot of heats again, the temperature of motor is raise.Too high temperature not only can make efficiency of engine reduce greatly, and causes motor easily and connect the damage of the miscellaneous part on it.So, in the design of motorcycle engine, making, often need to make motor to have thermal diffusivity preferably, the Temperature numerical of the motor in the work is controlled in the allowed band.The radiating mode major part of traditional motorcycle engine is air-cooled, and some adopts the mode of offering the air channel on cylinder head.But on cylinder head, offer the air channel, the motor heating problem in the time of also can only solving proper functioning, and fail to solve that engine cold starts, the problem of the very big noise that produces during the work of hot machine.
The model utility content
At the deficiency that prior art exists, the purpose of this utility model is to provide a kind of can either reduce the noise that engine cold starts, produce when hot machine is worked, and does not influence the petrol engine cylinder head of its power again.
The realization the technical solution of the utility model is as follows: a kind of petrol engine cylinder head, comprise the cylinder head matrix, and its difference is that cylinder head matrix front end is cast with " mountain " font ironcasting.
Three cylinders on described " mountain " font ironcasting are provided with two bolts hole, are used to install valve rocker arm assembly.
Advantage of the present utility model is, because the material of " mountain " font ironcasting is a cast iron, its thermal expansion coefficient is more much smaller than the thermal expansion coefficient of aluminum alloy, and valve rocker arm assembly is fixed on " mountain " font ironcasting, when so just having reduced engine cold startup, the work of hot machine largely, valve rocker that produces because of thermal expansion and the gap variable quantity between push rod, thus greatly reduce therefore and the noise that produces.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of " mountain " font ironcasting in the utility model.
Embodiment
How further specify the utility model below in conjunction with accompanying drawing 1 and Fig. 2 realizes;
As shown in Figure 1 and Figure 2, " mountain " font ironcasting 2 casts in cylinder head matrix 1, and three cylinders on " mountain " font ironcasting 2 are provided with two bolts hole 21,22, are used to install valve rocker arm assembly.
Claims (2)
1, a kind of petrol engine cylinder head, it comprises cylinder head matrix (1), it is characterized in that: " mountain " font cast-iron body (2) casts in cylinder head matrix (1).
2, according to the described petrol engine cylinder head of claim 1, it is characterized in that: three cylinders of described " mountain " font ironcasting (2) are provided with two bolts hole (21), (22).
