9 Prohibit operations under long-term overload condition. The diesel work
overload for a long time, the speed of engine will be slow, cause low speed of
the turbocharger, departure high effective area. The turbocharger can not
increase air inlet flow, but increase air inlet resistance, then the diesel
work badly , temperature rise of outlet water ,accelerating oil aging so
much as coking oil, the depravation of the whole lubricant system, a series of
grave faults, come into be a vicious circle, affect the service life of the diesel
and its reliability.
10 Do not stop the diesel immediate when you want to park. Likewise, a
3-5 minute idling speed is necessary. After temperature of the diesel drops
evidently, stop the diesel. Stopping the diesel at once when driving on
declining area is not allowed.
11 Pay attentions to start diesel under low temperature. when the ambient
temperature is too low or the vehicle stop for long time, strong sticky will affect
the diesel have oil pressure and flow. Check and fill lubrication for the oil filter
at the front of the turbo charging and its oil inlet pipe. Running 3-5 minutes in
idling speed after start the diesel, and then running at high speed.
Running at idling speed shall not exceed ten minutes. The long-term
idling speed running will cause temperature fall of the firebox, insufficient burn,
blocking fuel injection and cause coking of plunger ring and air valve. As for
turbo charging , low pressure of turbine and compressor or low speed of turbo
charging may leak oil into the turbine casing from the sealing parts.
When open and check the turbo charging, please operate after the diesel
is cooled. The turbo charging will be damaged if the diesel without inlet pipe
and oil filter.
When the diesel is heated, do not touch the turbo charging and its connections
to avoid scalding.
