What are the different types of diesel injectors?
The main types of injection systems include pump-line-nozzle, unit injector, and common rail.
What are the two main types of injectors?
Single-point or throttle body injection. Port or multipoint fuel injection. Sequential fuel injection.
What is the major difference between Split and splitless injection?
The overall design of this injection is similar to that of the split variant. However, there is one minor difference, i.e., the split vent is closed here before and while the injection of the sample takes place. That is why it is named as the “splitless” injection, as it lacks the split vent.
Are Cummins 5.9 and 6.7 injectors the same?
High-Pressure Injectors Both the 5.9 and 6.7 Cummins use a Bosch high-pressure common-rail fuel injection system. The difference is that the injectors in the 6.7 Cummins are rated for higher pressure and are specifically designed to handle it. They also require less voltage for operation.
What is a splitless injection?
In a splitless injection, the split vent is closed and left closed before and during the injection. As there is no split flow, the total flow is set at a dramatically reduced flow rate.
What is a PTV injector?
The Programmable Temperature Vaporization (PTV) option adds ballistic heating capability to the Heated Split/Splitless injector in order to accommodate large volume injections and thermal desorption applications.
Are there any weaknesses in the Cummins Engine?
While the 5.9 Cummins is a very robust engine, it does have a few weaknesses that can leave the truck stranded, but nothing that will lead to a catastrophic failure or meltdown. As part of our “What Breaks When” series, this week we’re taking a closer look at the 2003 to 2007 5.9-liter Cummins. 03-04 vs 04½ -07 What’s the Difference?
What does the third injection event do on a Cummins?
In addition, the later 5.9 Cummins also featured a third, post-injection fuel event after the main spray, and the main purpose is to reduce harmful emissions. The third injection event is said to have a slight negative impact on fuel mileage, however with aftermarket tuning, the loss in mileage can be restored.
What is the most restrictive intake system on a Cummins?
Speaking of heat, one part of the intake system on a Cummins that is the most restrictive is the intake horn. The stock part was designed to be about as aerodynamic as a brick, and the inside resembles a drinking straw.
What kind of nozzle does a Cummins Engine have?
The later 04.5 to 07 Cummins 5.9s featured a five-hole nozzle, a narrower spray pattern, and to match that pattern, a different shaped piston bowl needed to be used. In addition, the later 5.9 Cummins also featured a third, post-injection fuel event after the main spray, and the main purpose is to reduce harmful emissions.
