Abstract
The utility model discloses a four-cylinder double overhead automobile camshaft which comprises a cam and a shaft portion. The cam is arranged on the shaft portion in a sleeved mode, and the cam is used for both air inflowing and air exhausting. By means of changing of modeled lines of the cam on the camshaft, the lift values of two waists of the cam are increased, the largest lift of the cam is reduced, the fullness coefficient of the cam is increased, and accordingly abnormal sounds and noise of an engine are lowered, the torque point of the engine is increased to 115 N. m / 4500 turns, and emission performance of the engine is superior to that of an original machine model.
Description
Technical field
The utility model relates to a kind of camshaft, especially a kind of four cylinder double overhead motor car engine intake and exhaust distribution cam axle used.
Background technique
At present, the molded line of motor car engine intake and exhaust distribution cam axle overhead cam used is related to fullness coefficient and the inflation performance of cam, directly affect engine output, engine output torque, oil consumption and combustion noise etc., directly determine whether composition and the concentration etc. of harmful gas in sufficient combustion, exhaust emissions of fuel oil.The today of skyrocketing in energy prices, Consumer requires harsh today to automotive performance, and each manufacturer is all devoted to study the motor car engine cam profile that engine output is higher, oil consumption is lower.
Model utility content
The four cylinder double overhead automobile camshafts that provide a kind of maximum output high are provided technical problem to be solved in the utility model.
The technical solution of the utility model is as follows: a kind of four cylinder double overhead automobile camshafts, comprise cam (1) and axial region (2), and it is upper that its cam (1) is enclosed within axial region (2), and described cam (1) is that air inlet and exhaust share, and its lift that rotates a circle is as following table:
Beneficial effect: the utility model is by changing the molded line of camshaft overhead cam, improve the lift range value of cam two waists, reduce the maximum lift of cam, improve cam fullness coefficient, thereby engine abnormal noise and noise are reduced, make Engine torque point be increased to 115N.m/4500 and turn, and the discharge of motor is better than former type.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of cam.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As depicted in figs. 1 and 2, the utility model comprises cam 1 and axial region 2, and its cam 1 is enclosed within on axial region 2, and cam 1 and axial region 2 are one.Described cam 1 is that air inlet and exhaust share, and this cam 1 rotates a circle lift as following table:
Claims (1)
1. four cylinder double overhead automobile camshafts, comprise cam (1) and axial region (2), and it is upper that its cam (1) is enclosed within axial region (2), it is characterized in that: described cam (1) is that air inlet and exhaust share, and its lift that rotates a circle is as following table:
