Set of four (4) genuine new Bosch 0445110558 CRI2-16 electromagnetic common rail fuel injectors for Deutz KHD TCD 3.6L diesel engines. These OEM Bosch injectors are designed for precise fuel metering, stable rail pressure response, reliable engine performance, and long service life in agricultural, industrial, and heavy-duty diesel applications. The Deutz TCD 3.6 L4 is a 4-cylinder engine, so a complete set of four injectors covers the full engine.
For best results on a common rail engine, injectors should be replaced as a complete set so that fuel delivery stays balanced across all cylinders.
This set is compatible with selected Deutz-Fahr tractors and industrial equipment equipped with Bosch common rail fuel systems. Always confirm compatibility by Bosch number, OE number, VIN, engine serial number, or the identification number on the original injector before ordering.
Also known internationally as: Einspritzdüse / Injektor (DE), injecteur (FR), iniettore (IT), inyector (ES), injector (RO) — Bosch 0445110558 common rail injector for Deutz TCD 3.6L.

Why Replace Injectors as a Set
On a common rail diesel engine, injector wear progresses across all cylinders. Replacing the full set of four keeps injection quantity and timing balanced, avoids uneven cylinder loading, reduces the risk of a repeat workshop visit, and protects the new parts if one cylinder was already running rich or lean. Many workshops require a complete set replacement to validate the repair.

| Are these genuine Bosch fuel injectors? | Yes. These are genuine Bosch OEM common rail diesel fuel injectors. |
| What is the main Bosch part number? | The main Bosch reference number is 0445110558. |
| Which engines use Bosch 0445110558? | This injector is used in Deutz TCD 3.6L L4 diesel engine applications in agricultural and industrial machinery. |
| Why buy a set of 4 instead of a single injector? | Replacing all four injectors keeps fuel delivery balanced across cylinders, reduces the chance of a repeat repair, and is often required to validate the workshop fix. |
| What type of injector is the Bosch 0445110558? | It is an electromagnetic solenoid common rail fuel injector belonging to the Bosch CRI2-16 OHW family. |
| What causes common rail injector failure? | Common causes include fuel contamination, water in fuel, metal particle contamination from a failed high-pressure pump, insufficient fuel filtration, and wear from extended service. |
| Should the diesel engine be diagnosed before replacing the injectors? | Yes. Professional diagnostics are strongly recommended before replacement to confirm the injectors are the source of the fault. |
Diagnostic Information
Common Symptoms of Fuel Injector Failure
Hard starting, long cranking, engine no-start condition, unstable idle, engine misfiring, loss of power, rough running, excessive smoke, abnormal fuel consumption, check engine warning light, or visible fuel system contamination may indicate problems within the diesel fuel system or common rail injection system.
These symptoms may also be caused by the high-pressure fuel pump, rail pressure sensor, fuel metering valve, ECU faults, fuel contamination, or other diesel engine management issues.
Installation and System Check
Before replacing common rail fuel injectors, a professional diagnostic inspection should be performed, including rail pressure testing, injector leak-off testing, fuel contamination inspection, ECU fault-code analysis, fuel filter inspection, and diesel fuel quality inspection.
If a previous injector failed internally or if the high-pressure pump failed and released metal particles into the fuel system, the common rail, fuel lines, fuel filter housing, and remaining injectors should also be inspected and cleaned or replaced if necessary. Installing new Bosch injectors into a contaminated fuel system may result in immediate repeat failure.
