Premium Diesel Injector — Cummins PT Fuel Injector 3095773 Engineered For Power, Precision & Proven Durability in Common Rail Diesel Systems

In heavy‑duty diesel applications where power and consistency are non‑negotiable, your engine's fuel delivery system defines its heartbeat. The Cummins PT Fuel Injector 3095773 is a high‑precision mechanical injector engineered to meet the stringent demands of large industrial and commercial diesel engines - particularly those that rely on PT (Pressure‑Time) fuel systems. Designed to work seamlessly with Cummins K‑series platforms, this injector blends rugged durability with refined fuel delivery control, ensuring your equipment runs efficiently under the most strenuous conditions.

Rather than merely being another replacement part, the 3095773 is crafted to uphold Cummins' OEM standards of quality and reliability. It is commonly used in engines such as KTA19, KTA38, and larger Cummins blocks - platforms known for industrial power generation, marine propulsion, and heavy construction machinery.

🔹 Mechanical PT Operation - In PT systems, injectors are actuated mechanically using cam action and controlled timing, ensuring fuel is injected at the right moment without relying on electronic actuation.
🔹 Robust Construction - Built to withstand high pressure, heat, and vibration common in heavy diesel environments.
🔹 Direct OEM Fit - Designed as a direct replacement for Cummins part number 3095773, maintaining original performance and compatibility.

The versatility of the 3095773 injector makes it ideal for a variety of heavy‑duty uses where dependable fuel delivery is mission critical:

📌 Industrial Generators: Keeps power units stable under continuous load.
📌 Marine Engines: Delivers consistent injection timing even in high‑vibration sea conditions.
📌 Construction & Mining: Reliable combustion performance on rugged worksites.
📌 Heavy Trucks & Transport: Durable injector design supports long haul operations.

Across these diverse settings, the injector contributes to dependable engine power delivery - a core requirement for professionals relying on uninterrupted operation.

Though detailed OEM spec sheets aren't always publicly released, trusted sources and part listings highlight the defining features of the 3095773:

✔ Part Number: 3095773 - Genuine Cummins PT Fuel Injector.
✔ Weight: Approximately 1.14–1.2 kg - reflecting a solid mechanical build.
✔ Applications: Compatible with a spectrum of Cummins diesel engines including K19, K38, K50 variants.
✔ Performance: Precision fuel atomization and timing enhance engine combustion efficiency and thermal stability.

In PT systems, reliable injector performance is especially vital because it directly influences combustion timing, fuel quantity accuracy, and overall engine responsiveness - all factors that translate into real‑world efficiency gains.

.

Q1: How does the 3095773 differ from electronic common rail injectors?
A: It relies on mechanical pressure‑time operation rather than ECU‑driven high‑pressure pulses, favoring robustness in heavy‑duty duty cycles.

Q2: Can this injector improve emissions performance?
A: Yes - improved atomization and timing help promote more complete combustion, which can reduce soot and unburned hydrocarbons.

Q3: Is the injector compatible with all Cummins diesel engines?
A: It is designed for specific PT compatible models like KTA19, KTA38, QSK19 and larger engines; always verify engine model before purchase.

Q4: How often should injectors be inspected in a heavy‑duty engine?
A: Regular inspections aligned with manufacturer maintenance intervals and fuel filtration checks help sustain injector performance.

Q5: Are aftermarket versions as reliable as OEM?
A: Generic parts may vary in material quality and tolerance; OEM injectors provide verified performance with traceability.

Q6: What practical differences will operators notice after installation?
A: Many users experience smoother idle, reduced smoke, and more predictable power delivery under load after installing genuine injectors.
