This article goes into the history of the P7100 Fuel Pump and the. Since the inception of the Cummins 4BT the company has only used 4 different types of Bosch Fuel Pumps for its B Series engines; which are popular in Dodge Trucks. From 1983-1993 the early 4BT and 5.9L engines used a VE mechanical style rotary pump then switched to the popular Bosch P7100 mechanical inline pump in 1994.

From late 1998 until 2002 Cummins made the big switch from mechanical pumps to electronic injection with its VP44 rotary engineered pump design. The latest Cummins Pump is the switch to the common rail injection system in 2003 with the Bosch CP3 injection system. P7100 Camshaft Powered Design The P7100 pump is by far the most common and popular fuel injection pump used in the. The P7100 injection pump is engineered to be flange-mounted to the engine and works directly in conjunction with the crankshaft via the gear train. Autodesk 3ds Max 9 Animation Tutorial Manual on this page. The gear train powers the pump trough a time reduction gearset system. The drive plate is the main component in the geartrain and is connected to the internal injection pump camshaft. It is important to note the P7100 has its own small camshaft outside of the camshaft of the 4BT or 5.9L. The cam acts like the brain of P7100 activating various systems within the pump. Operat Manual Sokkia Auto Level. It mostly controls the critical timing components within the pump and is housed in the injection pump cambox. The cambox is the name for the lower portion of the pump that houses the camshaft, tappets and central oil sump. The camshaft, much like the camshaft in the actual engine, is supported by main bearings which allow it to “float” on a cushion of oil within the cambox. Proline Fridge Manual. The camshaft inside the P7100 is designed to allow one distinct cam profile with a tappet lifter per engine cylinder. Each lifter is responsible for driving power to a pump element which is guided by a standard plunger and barrel application. Unlike other fuel systems, the barrel is immobile and is bored with holes in its upper portion which are exposed to the fuel-storage gallery. This is that process: The fuel is firstly metered through the barrel ports and is stopped when the plunger obstructs the opening. mognational.com/wp-content/plugins/formcraft/file-upload/server/content/files/1626f0a77c4507---bosch-rps-software-manual.pdf

The plunger is pressure loaded by a spring and designed to ride the actuating cam profile which creates a constant plunger stroke allowing the right amount of fuel into the charging gallery. The P7100 uses a port-helix fuel metering system which creates constant equal pressure on in both the pumping chamber and the helical recess. The P7100 fuel injection pump was hugely.

The very mention of this legendary mill seems to reinvigorate the never-ending mechanical vs.But, this isn’t another holy grail piece where we worship the almighty 12-valve. Instead, we’re highlighting the biggest reason for this engine’s celebrity: the Bosch P7100. The Bosch P7100 is arguably the single most recognizable symbol of diesel performance. It represents easy horsepower for those handy with a wrench, huge horsepower for anyone willing to spend some money and — like the Cummins engine it was bolted to — million-mile durability. We’ll begin with the mods that won’t cost you a dime, but that can add more than 100 hp. Then we’ll explore the internal upgrades that can take this pump from mild to wild. This marvel of mechanical engineering is fairly complex. Think of the P-pump as a mini inline-six cylinder engine bolted to the side of your inline-six cylinder engine. There are many moving parts inside. In addition to dictating when the governor arm hits the AFC arm, the AFC is in charge of controlling the pump’s fuel rate at low boost. By sliding the AFC housing forward (toward the front of the pump) and backing out the pre-boost screw (on the backside of the AFC housing), fueling can be brought in at a much lower rpm, the governor linkage is altered and the rack is adjusted forward. And when combined with a star wheel adjustment (located within the AFC housing), as much as 200 lb-ft of torque can be added, along with a peak horsepower increase of 50 to 60 horsepower. The fuel rack controls the amount of fuel that’s allowed to enter the pump’s plungers and barrels. The star wheel is accessed via the top of the AFC housing, and adjustments should be made in very small increments. If you go too far, heavy smoke will result. Go too little, and you won’t see the power gains you’re after. It’s up to you to find the right balance here. The popular “Mack rack plug” shown above increases rack travel from 19 mm (stock) to 21 mm. While 2 mm might not sound like much, the Mack rack plug adds roughly 70 cc’s worth of fuel to the mix and can be good for anywhere between 10 to 35 additional horsepower depending on your pump’s overall combination (specific P7100 model, delivery valves, fuel plate setup and injectors). It’s important to note that the best way to install the Mack rack plug is with the pump off the engine. If the pump stays in place, some grinding of the timing cover will be in order. In addition, the Mack rack plug isn’t typically recommended for 215 hp pumps (the P7100 used on ’96-’98 trucks with five-speed manual transmissions). While there is no shortage of aftermarket fuel plate options (along with plenty of custom-made, one-off versions), removing the fuel plate completely will yield more rack travel and considerable power gains (typically 35 to 40 hp). Disable the wastegate on the turbo (increasing boost production by 10-to-15 psi) and you could find another 10 to 20 hp. As far as performance investments go, picking up 100 to 120 hp for free is a no-brainer! The delivery valves are positioned inside delivery valve holders, both of which are positioned between the plunger and barrel assemblies and the injection lines that feed fuel to the injectors. Aftermarket delivery valve holders with a larger internal orifice (shown above) allow more fuel to travel through them. Aftermarket delivery valves offer higher flow (up to 100 cc’s), with some being application specific (i.e., some are good for towing, some good for daily driving, while others are reserved solely for performance). Common delivery valves used in the P7100 are 181’s, 191’s, 024’s, 022’s and full cut units, with the full cuts typically being reserved for dedicated sled pull, drag race or dyno applications. Popular kits from Dynomite Diesel Performance, PacBrake, BD Diesel and Industrial Injection provide full fueling up to 4,000 rpm, with even higher governor springs being available for competition-ready pumps that have been properly set up on a test stand. It’s important to note, however, that stiffer valve springs need to be installed in the head if you plan to spin the engine beyond 3,500 rpm or run big boost. For all-out competition pumps, companies like Scheid Diesel and Columbus Diesel Supply offer governor springs that provide full fueling up to 7,000 rpm! Increasing the diameter of the plungers and barrels from stock (12 mm) to 13 mm adds immense fueling potential. Shops like Scheid Diesel, Columbus Diesel Supply, Northeast Diesel Service and Hart’s Diesel are highly reputable in the 13 mm (or larger) P-pump world. The cam features one profile for each individual plunger and as the cam rotates the plungers are driven up and down within their respective barrels. In extreme horsepower applications, the cam inside the P7100 is swapped out in favor of a unit with a more radical profile. With a more aggressive cam, more fuel is injected — and it’s done at a quicker rate. The camshaft pictured above comes from Hamilton Cams; when it’s used in a 13 mm P7100, it can inject 11 percent more fuel volume than a stock cam. It’s also good for as much as 80 additional horsepower. A P7100 set at the factory timing mark will only mildly benefit from the modifications explained above. However, a pump that’s set at 18 to 20 degrees of timing advancement will see impressive gains. The 18 to 20-degree mark is the unofficial sweet spot for timing on a P-pumped Cummins in that it allows for good all-around power, drivability and cold-start performance. While considerably more power might be made with 25 or 26 degrees of timing, drivability will trend downward — not to mention that getting the engine to fire up in cold weather can become a chore. If you plan to tinker with your P-pumped Cummins, know that you will likely be performing some type of upgrade to the transmission in order to enjoy the added horsepower and torque. Recognizing that every individual's motoring journey is unique, we seek to give form to both untold as well as celebrated facets of the automotive world. We invite you to get behind the wheel with us, it's certain to be an interesting drive. Disclaimer: Sedo maintains no relationship with third party advertisers.

Please help improve this article by introducing citations to additional sources.Traditionally, the injection pump was driven indirectly from the crankshaft by gears, chains or a toothed belt (often the timing belt ) that also drives the camshaft. It rotates at half crankshaft speed in a conventional four-stroke diesel engine. Its timing is such that the fuel is injected only very slightly before top dead centre of that cylinder's compression stroke. It is also common for the pump belt on gasoline engines to be driven directly from the camshaft.The pistons have a constant stroke volume, and injection volume (i.e., throttling) is controlled by rotating the cylinders against a cut-off port that aligns with a helical slot in the cylinder. When all the cylinders are rotated at once, they simultaneously vary their injection volume to produce more or less power from the engine. Inline pumps still find favour on large multi-cylinder engines such as those on trucks, construction plant, static engines and agricultural vehicles.It uses a single injection cylinder driven from an axial cam plate, which injects into the individual fuel lines via a rotary distribution valve. Later incarnations such as the Bosch VE pump vary the injection timing with crankshaft speed to allow greater power at high crank speeds, and smoother, more economical running at slower revolution of crankshaft. Some VE variants have a pressure-based system that allows the injection volume to increase over normal to allow a turbocharger or supercharger equipped engine to develop more power under boost conditions.Poorly maintained and worn engines can consume their lubrication oil through worn out crankcase ventilation systems and 'run away', causing increasing engine speed until the engine destroys itself. This is because most diesel engines only regulate their speed by fuel supply control and don't have a throttle valve to control air intake.From the 1990s an intermediate stage between full electronic control were pumps that used electronic control units to control some of the functions of the rotary pump but were still mechanically timed and powered by the engine. These pumps were used to provide better injection control and refinement for car diesel engines as they changed from indirect injection to much more efficient but inherently less refined direct injection engines in the 1990s. The ECUs could even vary the damping of hydraulic engine mounts to aid refinement. BOSCH VP30 VP37 VP44 are example pumps. Since then there has been a widespread change to common rail diesel systems and electronic unit direct injection systems. These allow for higher pressures to be developed, and for much finer control of injection volumes, and multiple injection stages compared to mechanical systems.By using this site, you agree to the Terms of Use and Privacy Policy.
