Abstract

U ovom radu opisana je pogonska grupa Caterpillar C7 koja se nalazi u Oshkosh M-ATV
američkom vozilu u sastavu Oružanih snaga Republike Hrvatske. Vozilo je dizajnirano s
naglaskom na zaštitu od mina. Pogonska grupa Oshkosh M – ATV vozila je Dieselov motor. U
odnosu na Otto motore, gdje se paljenje smjese izvodi svjećicom, kod Diesel motora u cilindru
se uslijed visokog tlaka smjese goriva i zraka odvija samozapaljenje. U vozilo Oshkosh M –
ATV ugrađena je posebna izvedba Caterpillar C7 motora od 370 konjskih snaga. Ovaj pogonski
sustav s obzirom na prijeđenu kilometražu nije imao značajnijih kvarova, ali kao i svaki drugi
sustav zahtijeva preventivno i korektivno održavanje. Za razliku od drugih motora, Caterpillar
C7 motor koristi Hydraulically actuated Electronically controled Unit Injector1
(HEUI) sustav direktnog ubrizgavanja goriva. U ovom radu HEUI sustav uspoređen je sa sustavom pumpa –
vod – brizgaljka (PLD), sustavom pumpa - brizgaljka (PDE) i Common Rail sustavom za
ubrizgavanje goriva.

Abstract (english)

This paper describes the Caterpillar C7 engine used in Oshkosh M-ATV American vehicle
within the Croatian Armed Forces. The vehicle is designed with an emphasis on mine protection.
The engine of the Oshkosh M-ATV is a Diesel engine. Compared to Otto engines, where the
mixture is ignited by the spark plug, Diesel engines have self-ignition in the cylinder due to the
high pressure of the fuel and air mixture. The Oshkosh M-ATV is equipped with a special
version of the Caterpillar C7 engine with 370 horsepower. This engine did not have any
significant failures due to the mileage, but like any other system requires preventive and
corrective maintenace. Unlike other engines , the Caterpillar C7 uses a Hydraulically actuated
Electronically controled Unit Injector (HEUI) direct fuel injection system. In this work the
HEUI system is compared with the PLD, PDE and Common Rail fuel injection systems.
