PT fuel injector
QSN8551. Early electronic control used Cummins self-produced PT fuel injectors, without Bosch matching fuel injectors; Only a small number of Bosch low-pressure fuel pumps have been upgraded to the common rail version, and the mainstream PT system does not come with Bosch high-pressure fuel components.
Bosch fuel injector
QSK19/QSK38/QSK50/QSK60 (CM2150/CM2250 electronic high horsepower common rail), the entire series of Bosch dedicated XPI ultra-high pressure common rail system, high-pressure oil pump and injector are all manufactured by Bosch, divided into two sets of part numbers: basic version and upgraded NX improved version.
Bosch fuel pump
CP9 is a multi plunger radial high-pressure common rail oil pump developed by Bosch specifically for high-power industrial/marine/generator V-type large displacement diesel engines. It is compatible with Cummins MCRS common rail system and is divided into CP9.2 (dual plunger QSK19), CP9.3 (three plunger QSK38/QSK50), and CP9.5 (five plunger QSK60)
PT fuel pump
QSK19/QSK38/QSK50/QSK60 (MCRS electronic control common rail model, National III/National IV/Euro III or above emissions): A complete set of Bosch high-pressure common rail CRIN+CP9 system for large engines, Bosch exclusive matching high-pressure oil pump and electronic fuel injector, Cummins original parts are all manufactured by Bosch.

Products Description
Complete analysis of Bosch's Cummins QSN855/QSK19/QSK38/QSK50/QSK60 fuel supply system
Pre key distinction: Two sets of fuel systems
1. QSN855 (NT855/QSN14): The old mechanical PT fuel system, without Bosch electronic control common rail matching, original Cummins PT pump+mechanical fuel injector, Bosch does not supply;
2. QSK19/QSK38/QSK50/QSK60 (MCRS electronic control common rail model, National III/National IV/Euro III or above emissions): A complete set of Bosch high-pressure common rail CRIN+CP9 system for large engines, Bosch exclusive matching high-pressure oil pump and electronic fuel injector, Cummins original parts are all manufactured by Bosch.
1、 Cummins QSK series (QSK19/38/50/60) Bosch high-pressure oil pump CP9 series
1. Oil pump model and corresponding model
Bosch official model: CP9 modular multi plunger high-pressure common rail pump (special high flow oil pump for engineering machinery/ships/generator sets)
QSK19: CP9.2 (dual plunger), Cummins OEM part number: 2888712/4306517
QSK38/QSK50: CP9.3 (three plunger), OEM parts: 2867147/2867149
QSK60: CP9.5 (five plunger super large flow), OEM parts: 4306515/5471754
2. Core Structure and Parameters of CP9
1. Drive mode: engine gear chamber timing drive, independent camshaft, forced oil lubrication (different from CP3/CP4 fuel self-lubricating)
2. Built in low-pressure gear oil pump: 0.6-1.0 bar pre oil supply, with oil-water separation and adaptive oil circuit
3. Electric control metering valve SCV (Bosch F00BJ00004): PWM duty cycle regulation of oil intake, control rail pressure 1600-2200 bar
4. Limit parameters
Maximum system pressure: 2200 bar
Single plunger with large single displacement, suitable for single cylinder high-power cylinders up to 450kW
Designed with a durability of 20000 hours, specifically for mining/ship heavy load scenarios
5. Oil circuit logic tank low-pressure delivery → filter element → CP9 built-in gear pump pre pressure → SCV metering → high-pressure plunger compression → common rail accumulator → CRIN injector
3. Advantages of CP9 over regular CP3/CP4
Oil lubricated plunger, diesel oil has a much higher tolerance to water and impurities than CP4;
Modular plunger, single plunger can be replaced separately if damaged, without the need for whole pump replacement;
The five plunger version CP9.5 is compatible with the 16 cylinder QSK60 ultra large displacement, and the fuel supply flow rate is more than three times that of CP4;
24V electronic control drive, matched with large industrial engine ECM.
