Diesel engine can not be started for several reasons Analysis
Prerequisite
for the normal operation of the diesel engine is good atomization of
diesel accurate and timely injected into the combustion chamber and the
combustion chamber of compressed air to reach a sufficient temperature
to fire outbreak. To
satisfy these two conditions, there must be at a sufficiently high
speed diesel engine starting and making a certain temperature within the
cylinder. When the diesel engine can not be started, it should start working,
and compression diesel engine fuel supply system and other aspects of
the reason.
(1) the ambient temperature is too low. At low temperatures, the diesel engine warm-up work should be prepared, otherwise difficult to start.
(2) cranking speed is low. For
hand start diesel engine, it should gradually increase the speed, and
then the non-decompression decompression handle into position so that
the cylinder has a normal compression. If
the decompression valve mechanism to adjust properly, or resisted the
piston, they tend to feel the car shake very laborious. Its characteristics are a part of the crankshaft will not turn to move, but can return to. At
this time, in addition to check the pressure outside the organization,
you should also check whether the timing gear meshing relationship
wrong. For
diesel engines use electric starter, if the cranking speed is extremely
slow, most of the starter system weakness, the diesel engine itself
does not indicate a fault. Electrical
lines to deal with aspects of detailed examination to determine whether
the battery is fully charged, the wires connections are tight and the
starter is working properly.
