Abnormal burning four-stroke motorcycle engine oil

If the four-stroke motorcycle engine oil into the combustion chamber or exhaust, burning oil to take the blue smoke will seem failure. Exclude such failures, normally of great quality replacement valve oil seals, piston rings and so on. But fjust aboutme vehicles, the use of these usages can not mainly eliminate the burning oil hazard Lanyan failure. Take the blue smoke of burning oil unusual occasion of failure is differ from the valve oil seals, piston rings and other customary wear and tear of excessive cylinder wear failure and the failure causes of the following:

a piston ring failure Shangcuan oil, Fault decomposition parts consist in ...: half the piston wear (piston pin direction), no black carbon deposition, the other half from the top piston ring groove to the bottom pin is always black, yellow, coke coke, no signs of wear. This failure is primarily due to the direction of the cylinder piston pin in the side of favor around the irregular pressure, loss of independent patronize, in a free circulation of the working conditions, eccentric wear of piston rings due to quick, resulting in open space, backlash to the maintenance limit. Lose their original feature of scraping the oil seal. Most of such failure for several reasons:

1, these vehicles are particularly serious due to burning oil, and check the oil remiss owners, grant the engine short of oil, causing rod small end and piston needle lock necrosis. And in the accident of failure, repairs to an erroneous piston pin removal methods, such as tapping, ticketing, so that the rod deformation or perversion, bias the instruction of the side of the piston pin.

2, the majority of the replacement roller crankshaft, interlocking rod, the crankshaft bearings are press-fit side is no in area, leading to the megalopolis line of the original cylinder connecting wand heart line discrepancy is too large, squeeze the small end of piston rod prejudice cylinder side.

3, so the box on the crankshaft limit stop wear solemn space between the crankshaft axis activity. Flywheel balancing deserving to damage or solemn crankshaft concentricity tolerance, in the going state deserving to centrifugal compel so that the overall shift to the side of the crankshaft. Repair the mistake have to be corrected or replaced with standard crankshaft convergence. At the same time should be replaced valve seal,GHD Pink Limited Edition, piston rings, cylinder and so on. 1,2 for the above class fails, setup the cylinder in the cylinder will detect installation complicated, especially large stop, put the piston in the cylinder after cylinder pressed into the cylinder wall side,GHD Classic Straighteners, the other side of the gap is quite large, with the thumb squeeze pressure side, and not sign of the gap bigger.

Second, the valve guide clearance is too large, the oil caused by loose below the channeling catheter. Oil from the valve guide and valve rod and the cylinder head gap or junction catheter into the combustion chamber or exhaust. Symptoms were as follows: airway (not opened valve components) catheter and the valve at the invasion has traces of oil or black carbon deposition.

1, valve, duct space among the latter 2 are too many dress and tear, apt the upkeep of the on limits 0.06MM, valve reciprocating motion,GHD Diamond Flag 2011, because the gap is too large, so deflection is likewise colossal, resulting in valve seal failure. Such failures are constantly accompanied along hardship in beginning, cylinder pate rumpus,GHD Green Butterfly 2011, lack of motivation and so ashore, extra prevalent in automobiles. The fix,GHD NZ, premier retard the cylinder brain, inlet duct and valve brain airway row cone fashion. Inlet fuel infiltration apt have extra than traces of the extravaganza. Check with the gap, use a new valve and a criterion catheter with the cylinder head. If the outcome of superfluous dress and tear ducts, you absence apt replace the catheter, catheter for a current catheter and approximation of the old,GHD Hair Straightener NZ, to assure that its elevation, the same size. Replace catheter valve cylinder head and so the need because grinding actions.

2, while loose valve advisers, cylinder head and oil from the catheter and nigh the gap junction leakage or inhalation of the combustion chamber and exhaust ports. Performance of characteristic symptoms: loose atmosphere intake duct, the inlet there are traces of the oil infiltration, cold start blue smoke behind unload, most piston ring failure that occurred as burning oil breakdown; exhaust duct loose, the chilly start No blue smoke exhaust, exhaust pipe tail oil droplets in the hot car status, especially in cheap gear cumbersome, there are clear blue smoke eruption (as in the continuity of the ramp tin be checked to.) Repair of such traffic, the surface can be washed weekly in the bottom of some of catheter burr-like bump at the same time carefully with the punch catheter fixed in the cylinder head is somewhat symmetrical around the cavity punch small pits, so that the smaller diameter, so that pipe and tank head large enough value of interference. And replace the O-ring catheter, and catheter fixed in the bottom hole catheter coated with some liquid sealant. And then press into the catheter (or into) the cylinder head (Note: If the old and the new catheter valve repair with the gap approached a restrict, should be replaced with new pipe. Combination of the above measures to make the new tube and cylinder head has ample amount of interference, not to loose themselves in the hot state).

In increase, marred cylinder head pad, cylinder head and impudence tangle deformation also results in inspiratory inhalation room in flaming oil, flaming oil to fashion the failure to take the blue cloud. More performance for such a failure the cylinder head and cylinder with grease infiltration coalition. Repair, replace the cylinder head and cylinder head pad and ground plane.
