Such ‚ ‚ compressed air in cylinder compression will enter a peach shape nozzle needle valve body cavity; In ‚ flame will spray into the oil nozzle needle valve peach shaped cavity. Results the nozzle needle valve and needle valve of diesel injector nozzle is easy to damage ‚ annealing. Spray the harm of oil pressure is too high: (1) spray oil pressure is too high ‚ fuel atomization, although there is a certain improvement ‚ ‚ but throughout the distance is too big will fuel injection on the combustor wall ‚ easily for the combustion chamber is not oil film combustion system ‚ can also lead to incomplete combustion, exhaust smoke and carbon deposition. And ‚ engine to knock. (2) the injection pressure spring load increase ‚ easy cause spring elastic weakened or broken; Make the nozzle needle valve and needle valve seal cone between mechanical shock load increase ‚ accelerated wear and liquid water flushing; Due to the increasing peach shaped cavity pressure ‚ except on spray hole infiltration ‚ drip ‚ prone to serious carbon ‚ but also can make the nozzle needle valve and needle valve body between the guide surface leakage losses increase ‚ that back sandstones, serious, fuel injection quantity decreased. Because of the high pressure needle valve in the needle valve take easy stuck in the closed position ‚ can also lead to engine "short leg", power down, work is not stable. (3) fuel injection pump fuel supply load increases ‚ except within the q of plunger and plunger sleeve increased leakage loss (i.e., drain oil) ‚ liquid wash also aggravate ‚ accelerated wear; Also make the roller body adjustment block (or adjusting screw) bearing surface, the camshaft CAM parts such as load increases accordingly ‚ also accelerated its wear and tear. Among multi-cylinder machine such as cylinder ‚ high injection pressure will cause the fuel injection pump body shape. Nozzle once stuck in closed position without timely find out ‚ to dongfanghong 75 tractor as an example when ‚ even lead to the camshaft, woodruff key, spline housing and spline flange damage such as driving parts.
