final Flashcards
AMBAC model 100 pump, headcore, plunger, metering sleeve, and delivery valve are all contained in
The Hydraulic head assembly
Bosch VE Distributer pump has how man pumping plungers
no plungers; uses a cam roller plate
Lucas DPA, Stanadyne DM & DB have in common
opposed plunger pumps, one metering sleeve, rotor distributor to meter fuel through the hydraulic head
mechanical type distributor pumps use what type of metering
Helix and Sleeve
governor weight retainer in an opposed pluger distributor pump is fixed to the
rotor drive end
pourpose of delivery valves
keep injector line full, rapidly end injection,
what type of transfer pump is found in the Bosh VE and Stanadyne distributor pumps
Vane pump
when does the fuel get metered in the opposed plunger stanadyne pump
before fuel pressurization
the throttle adjusts what internal components
tension of governor spring
what does the automatic advance mechanism do
control fuel pressure, slightly rotates cam lobe, increase injection type as engine speed increases
Six types of governors
mechanical, pneumatic, servo, hydraulic, electric, electronic
what does a governor do
controls volume of fuel injected, keeps engine under control, regulate engine speed
governors are typically found within
injection pump
variable speed governors are found on what
tractors, locomotives, marine engines
limiting speed governors are found on what
highway vechicals
