2 emissions Layan and the reasons for the exclusion method

Layin the result of emissions from the combustion chamber is excessive caused by burning oil. This fault for the following reasons:

(1) increase oil sump excessive. Too much oil, with high-speed operation of the crankshaft to Gangbi spatter, and Cuanru chamber. Exclude downtime is about 10 minutes, then check the oil benchmark, the row will be an excessive amount of oil swap.

(2) cylinder, piston components wear serious gap too large. If the gap too large, oil will be a substantial Cuanru combustion chamber, accompanied by the engine crankcase emissions increased approach is timely replacement of worn parts.

(3) piston rings lost role. Piston Ring flexibility such as inadequate, the death card in the Central coke bed, or in the mouth with the ring has been online, or circular hole to plug oil, the oil will lead to a large number Cuanru combustion chamber, there Layin emissions. Approach is removed piston rings, removing coke, the heavy cloth ring I (Upper and Lower Central mouth recommendations staggered 180 ��) and, if necessary, replacement of piston rings.

(4) valve and catheter gap too large. As wear, resulting in a gap between a large, in the inlet, rocker oil by the amount of respirable indoor combustion chamber, the approach is the replacement of worn valve and catheter.

(5) to take Layin of other causes. If too thin oil, and high oil pressure, engine running-not good, it will cause oil combustion and run Layan.
