Injectors and Nozzles for Caterpillars

  • Enhanced fueling and spray patterns for Caterpillar engines to meet your horsepower requirements
  • For off road applications our injectors can develop more horsepower then marine injectors

All our high-flow nozzles are made to order and whether you are looking for a little fuel economy or enough horsepower to lift your steer axle off the ground we can make it happen. By increasing the flow through the nozzle tip and increasing the pop-off pressure, we can obtain this. If you're interested in these high-performance nozzles please allow three weeks for delivery. We also increase the pop-off pressure to clean up the black smoke and bring the injection timing back into specification. Did you ever wonder why a 425 Cat smokes when you increase the fuel delivery at the pump? This happens because as the amount of fuel being pumped through the nozzles increases the nozzle opens sooner and closes later than it was designed for and the timing is being advanced with the nozzle opening sooner. As we all know, advanced timing is bad for high horsepower diesels, regardless of whose name is on the valve cover. With the pop-off pressure increased the nozzle opens at the proper time and also closes sooner. Our custom high-flow Nozzles start at 20% more fuel and we have built them as high as 100% more fuel. However, that truck is only used for sled pulling at county fairs. Most of the nozzles we build are 20% to 30% over on the flow. Now please don not think that you will lose fuel mileage with bigger nozzles. That just is not true. A fuel-injected engine will only inject enough fuel to maintain the speed that you desire. It still takes about 276 horsepower to pull a van on level highway at 70 miles per hour and it does not matter if you have 700 hp. or 350 hp. It still takes the same amount of fuel to pull the load. Getting over the hill or mountain sooner, driving reasonably on the level terrain, and not speeding (especially if the wind is head on to you or at your side) makes fuel mileage. A powerful engine, properly driven, will give you better fuel mileage and you will be happier driving it.
