When this cylinder head leaves the factory, we explained that we can't breathe, and all the consequences of breathing are at our own risk, and there is no warranty.
In the past two years, oil prices have risen too fast, and many buyers still use it for gas.
The problem of idle jitter appeared after running for more than a year, and it appeared after changing for a month or two.
The original valve is a solid valve, and its high temperature resistance is far less than that of combustion gas.
Under the principle of thermal expansion and cold contraction, the original valve expands outward, pushing the valve guide, which swings left and right with the valve and breaks the seat ring.
As a result, the valve and seat ring are not tightly sealed, resulting in pressure and air leakage, insufficient combustion power and idling jitter.
We received too much feedback. Last June, our factory produced a number of valve guides, valve seats, valve oil seals and nano-valves made of special materials.
It has been in the testing stage before. From the first batch to now, there have been no problems such as idling jitter, cylinder shortage and pressure shortage.
In the factory, 65438+ In early February this year, the cylinder head kit was ready to go on the market, for all car owners who encountered this problem when changing this model to gas.
