Abstract :
at penelitian aims to determine the effect of the thickness of the shim against
ppressure andChanges carburetion in Isuzu Panther Nozzle uses fuel solar and
Pertamina dex mixed with polypropylene. The method used in this research is
mixing fuel from diesel and Pertamina dex mixed with polypropylene, including S
85% (diesel 85%+15% polypropylene, S 75% (75% diesel + polypropylene
25%), PD 85% (Pertamina dex 85% + 15% polypropylene, PD 75%
(Pertaminadex 75% + 25% polypropylene), with a variety of thickness nozzle
shimof 0.05 mm, 0.10 mm, 0.15 mm, 0.20mm, and 0.25 mm. The results in this
study menwave lowest viscosity values in PD 75% (pertamina dex 75% + 25%
polypropylene. The best pressure on the shim variation is found in the 0.10 mm
thick shim with a pressure of 155,6 Bar located in the mixture PP 15% + S 85%
and 0.15 mm thick shim whit a pressure of 168,6 Bar on a PP 25% + S 75%
mixture. Thelowest stress is located on the shim with a thickness of 0.05 mm in
the mixture of materials burn PD 75% + PP 25% with pressure 123.3 Bar. Results
The best fogging is located on the shim with a thickness of 0.10 mm at a mixture
of S 85% + PP 15% with an angle of 18.3° and 0.15 mm in S . mixture 75% + PP
25% with a large angle of 18°.
