The role of valve spring, how to divide ea888 valve spring

The valve spring we are talking about today is a part located between the cylinder head and the spring seat at the end of the valve stem. However, when asked what is the function of the valve spring, many friends said that the situation is not so good, and then we will give you an answer.

The role of valve spring

The function of the valve spring is to ensure that the valve (closed) can be seated in time and fit tightly, and overcome the inertial force generated by the valve mechanism when the valve is opened, so as to prevent the valve from beating when the engine is vibrated (damage its tightness) ), it can be said to be a very important valve part.

How to divide ea888 valve spring

Most of the ea888 engine valve springs are separated from the intake and exhaust, but there is no distinction between the front and rear positions. However, the intake spring is slightly thicker than the exhaust spring, mainly to provide a faster intake response. Secondly, the intake air is sparser than the exhaust spring, thus ensuring sufficient air intake. Of course, we can also distinguish by the paint spots that come with the original factory. Three spots are air intake and five spots are exhaust. So for some older models, green is the intake and red is the exhaust.
