mid term Flashcards
valve seat back leakage test
3-10 drops per min
two types of injectors
open or closed
pintal injector nozzels
indirect injection, small bore high speed engines
the aux hole on the pintal nozzels are for
cold start assistance
fuel is metered before reaching main injector pump
rotatary distributor pump
when cylinder #1 is TDC compression the companion is
cylinder #6 TDC exhaust
Particulate Matter is
dirt, sand, rust
how many type of fuel under ATSM
3
specific gravity of diesel
0.9:1
viscosity
measures of a fluids ability to flow of its thickness
fuel pick up is located
one inch off the bottom of the tank, large enought to supply the engine
largest percent of diesel exhaust gasses
nitrogen
higher the octance
the higher the compression can be before detonation
higher the cetance
shorter the ignaition delay
3 benefits of diesel engines
wider rpm, torque range, more fuel to power, longer engine life
