A diesel engine is a four stroke engine that
takes four turns to complete a cycle: intake, compression, power,
and exhaust.
Every once in a while, an engine “misfires.” If the engine is running perfect and all of the
cylinders are “firing” you could say there is no misfire. Once the air fuel
ratio inside the combustion chamber in any of the cylinders gets interrupted,
the engine will misfire.
One of the more common causes of engines
misfiring is a broken bolt or other internal working parts that have sheered.
The only way to replace this, since most bolts tend to become welded into the
engine due to intense heat and the application of sealants like Loctite, is
to drill out the bolt using a core
bit drill.
Because core bits have hollow centers, core bit
drills it can easily bore a hole in any aggregate material. The result is a
hole the size of the drill and a smaller "core" coming from the
center. The core holds the material in place, allowing the tool to cut a clean
hole through the material. Gila Tools core bit solutions are designed with
high diamond concentration for superior cutting performance, enhanced
productivity, and longevity.
It is important to identify and fix the cause of
misfires because misfires cause engine parts to become unstable due to excess
vibration. If not addressed immediately this can cause the engine to cease or a
number of other non-terminal malfunctions, but are just as dangerous.
When replacing a bolt, it is also important to
make sure that you get the right torque otherwise it will warp the engine. Bolts are graded
by tensile strength and are easily identified by the number of slash marks
on the head of the bolt. The more marks the higher the quality. Hardware store
bolts with no markings on top are usually soft, mild steel, grade 2 quality and
should be avoided like the plague.
