Diesel generator failure reason highlights

Diesel generatorsFault reason
First, diesel engine black smoke
1, turbocharger work effectively;
2, the valve assembly is poorly sealed;
3, injector precision coupling work effectively;
4, cam shaft assembly wear filtering;
5, air filter or intercooler overrupt.
Second, diesel engine is white smoke
1, injector precision dipping;
2, diesel grunge oil (ie, supercharger burning oil);
3. Excessive valve catheter and valve wear, oil leakage cylinder;
4, water in diesel;
5, high pressure oil pump work fault.
Third, during high load, the supercharger is red
1, injector precision dipping;
2, camshaft, follow-up arm assembly, rocker assembly wear excessive;
3, the intercooler is too dirty, the intake is insufficient;
4. The supercharger work is effective.
Fourth, diesel power power loss is large
1, the cylinder assembly is too large;
2, the injector precision coupling work is effective;
3, PT oil pump work effectively;
4, the normal work is not working;
5, supercharger work effect.
5. Diesel engine oil pressure is too low
1. The fit gap of the shaft gap is too large, that is, the shaft wool is too large;
2, various bushing and shaft gap wear is too large;
3, cooling nozzle or oil pipe drain;
4, the engine oil pump is effective.
6. The diesel engine temperature is too high.
1, water pump damage;
2, the thermostat is damaged;
3, fan belt, water pump belt is too loose;
4, the outside of the water tank is too dirty;
5. The ventilation conditions of the machine room are too bad.
Seven, the diesel engine is turbid
1, the gap between the cylinder assembly is too large;
2, the oil bottom shell has water;
3, there is a pull tuning.
Eight, diesel engine speed is unstable
1. Diesel machine has a fault failure for power loss;
2, PT pump electronic actuator wear filtering;
3, PT pump internal machine fault;
4, EFC electronic governor work results;
5, with air in diesel.
Nine, oil housing has water
1, cylinder set break;
2, cylinder rupture;
3, cylinder head rupture;
4, the cylinder jacket is broken;
5, the spray mouth copper set leaks.
Ten, the oil bottom shell has diesel
1, injector O-ring damage;
2, injector is poorly atomized, drip oil;
3. Improper installation;
4, the SCT valve has failed;
5, camshaft, follow-up arm, etc.
11. Diesel engine has an abnormal sound
1, valve and piston collision;
2, connecting rod screws, pistons and cylinder head collision;
3, EFC board fault;
4, PT oil pump failure causes stable oil supply;
5, injector drip oil burst;
6. The clearance of the diesel shaft watt is too large.
12. Diesel engine is too large
1, diesel axle gap is too large or axial gap exceeds the standard;
2, injector atomization is poor and knocking the tank;
3, the connection deformation of the diesel engine and the electric ball.
