What are fuel injector nozzles made out of?
Monark fuel injector nozzles are precise metal parts produced in a very controlled environment with numerous checks for quality control. They are manufactured with extremely close tolerances.
What do you need to know about Monark fuel injector?
This must read information is also included when you purchase a set of nozzles and in our Diesel Fuel Injector Cleaning, Overhaul and Testing Procedures manual. Monark fuel injector nozzles are precise metal parts produced in a very controlled environment with numerous checks for quality control.
Can a torque wrench be used on a nozzle?
You must use a torque wrench and torque to proper specs as outlined in the instructions, NO MORE. Over tightening can cause deformation of the new nozzle and lead to tip misfire, scoring and overheating. I had one customer send his nozzles back saying they were bad.
How does Scheid injector nozzle affect fuel flow?
A sac tip doesn’t have a tunnel or trough for the fuel, but instead a cone-shaped area for seating the pintle. 17 With the nozzle orifices enlarged, the feed passage in the injector body might become a bottleneck for fuel flow, so Scheid adds up to two extra feed passages with the EDM.
Can a diesel truck have an injector nozzle upgrade?
It stands to reason that if he can pull more than 2,700 horses out of a competition diesel pickup, he knows a thing or two about enhancing the fuel systems on a regular-duty, daily-driven truck. It turns out that for a modest increase of around 100 to 300 hp, just enlarging the orifices in an injector nozzle might be sufficient.
Can a spring biased nozzle cause an injector to fail?
These factors can all contribute to a decrease in nozzle opening pressure that can affect injection duration and for spring biased nozzles, allow hot combustion gas to enter the injector under high load conditions and lead to rapid injector failure [2197].
What happens when you open the nozzle valve on a diesel engine?
Depending on how the seating line of the nozzle valve wears and whether it travels towards the tip or away from the tip, nozzle opening pressure can increase or decrease and produce unwanted changes in injection duration and injection quantity. This was explained when discussing injection system components.
