Where does the oil go in a cat 3126 engine?
Cliff note version; engine oil is pressurized to around 3000 psi and sent to the fuel injectors (via HEUI pump) it uses that high pressure oil to push a piston inside the fuel injector (oil on top, fuel on bottom of piston) to atomize the fuel, the injectors are controlled by a solenoid on top of each.
