Engine detail — Tata 697 Turbotronn DICR
Below are the Tata 697 engine specifications you need before ordering a Tata LPT 1613 injector or a Tata LPT 1618 injector. The Tata 697 diesel engine is a turbocharged, intercooled common-rail unit; the nozzle listed here is the internal spray tip of the 0445110506 CRI injector fitted to the Tata 1613 engine and Tata 1613 turbo variants. Tata 697 engine displacement differs by truck, with 5.7 L on the LPT 1613 and 5.0 L on the LPT 1618. The nozzle code on the component and the pump number on the engine plate must both match before you fit a replacement nozzle.
| Engine code | 697 (Turbotronn DICR) |
| Layout | Inline-6, water-cooled, direct injection, turbocharged, intercooled diesel (typical of the 697 family — confirm on the plate) |
| Displacement | 5675 cc (5.7 L) on LPT 1613 · 5000 cc (5.0 L) on LPT 1618 |
| Tata 697 engine fuel injection pump type | Common rail — built to the Bosch CR reference design |
| Emission | BS III / BS IV (India Bharat Stage) |
| Torque reference | Reference — 490 Nm @ 1500 rpm (697 5.7 L BS III, per Tata Motors Bangladesh). Engine output figure, not a nozzle rating. |
Fitment verification — three checks before you order
| 1. Number on the injector body | Match 0 445 110 506 (also stamped 0445110506) on the parent injector, and the nozzle code DLLA138P2355 / 0 433 172 355 on the old tip |
| 2. Engine code on the data plate | Must read 697 Turbotronn DICR — not the Cummins B5.9 variant |
| 3. Vehicle and emission stage | Tata LPT 1613 (BS III / BS IV) or LPT 1618 (BS IV) — confirm build year and Bharat Stage |
Send my engine code for verification
The Tata LPT 1613 nozzle and Tata LPT 1618 nozzle applications both use the same DLLA138P2355 tip; the Tata OE 252501160140 number on the parent injector confirms the match before you order.
Product Overview
DLLA138P2355 is the Bosch CR-system nozzle code for the pencil spray tip inside the 0445110506 solenoid CRI injector, built to the Bosch 0433 172 specification of the original 0 433 172 355. This DLLA138P2355 injector nozzle atomises the fuel that the injector’s control valve has metered and the high-pressure pump has pressurised. Because the rail holds pressure continuously on a common rail system, the nozzle must produce a precise, consistent spray pattern – that is what keeps a common rail diesel engine smooth, economical and within its emissions calibration.
This listing supplies a new nozzle matched to the original 0 433 172 355 specification, not a remanufactured exchange. It is the internal spray component of the 0445110506 CRI injector on your Tata LPT 1613 or LPT 1618 – rebuilders fit it when the old tip shows wear, scoring or poor atomisation. The compatibility brand is Vidishi Auto; Bosch and Tata numbers above are reference interchanges only and are listed so workshops can match the part correctly.
A common rail injector nozzle of the DLLA P-code family is a pencil nozzle, which is the correct design for the 697 Turbotronn application. These diesel injector nozzles are the spray-metering components of the rail, and a worn fuel injector nozzle is one of the more common causes of common rail spray faults.
⚙ Common rail nozzle at a glance
The fuel injection system on these 697 units is a common rail system diesel layout: one high-pressure rail feeds every injector, so the injection pump’s job is to maintain rail pressure while each injector’s solenoid and control valve decide when to spray. Because pressure generation is separated from metering, the engine management holds a commanded rail pressure across the speed range, which is what keeps these 697 units quiet, frugal and inside their emissions limits.
When the nozzle inside one injector drifts outside its calibrated spray behaviour, that cylinder’s combustion balance is upset and the engine management system has to compensate with trim corrections. Replacing a worn tip with a correctly matched common rail diesel nozzle restores the balance across all cylinders.
A diesel common rail nozzle like the DLLA138P2355 sits at the tip of the injector, and every injector nozzle diesel circuit depends on its spray cone for clean combustion. The DLLA138P2355 common rail nozzle shares the same bore fit as the parent 0445110506 tip.

Direct interchange numbers for DLLA138P2355
How the reference numbers relate
DLLA138P2355 is the etched nozzle code on the pencil tip; 0433172355 is the Bosch reference number for the same nozzle. The nozzle fits inside the 0445110506 CRI injector. The unit supplied by Vidishi Auto is a new compatible nozzle crossing both numbers — it is not a genuine Bosch unit. Bosch nozzle cross references of other CRI series always need matching by the full number, never by the prefix alone. Search terms such as Bosch 0433172355, 0 433 172 355 and Tata 252501160140 all point at the same nozzle — if you are looking for a DLLA138P2355 equivalent, match the Tata OE number first, then the engine code.
Parent injector & internal reference numbers
The nozzle, valve and magnet-assembly numbers above are internal service components of the 0445110506 assembly — they identify individual parts inside the injector, not a complete unit sold as a standalone injector. Only 0445110506 / 0 445 110 506 (Bosch reference) and 252501160140 (Tata OE) identify the whole injector; DLLA138P2355 / 0433172355 identify the nozzle inside it.
Bosch and Tata names and numbers are shown strictly as reference interchanges for correct part identification. The unit supplied is a new compatibility nozzle marketed under the Vidishi Auto brand and is not a Bosch-branded product.
The 0433172355 Bosch nozzle serves as the reference equivalent of DLLA138P2355, and the 0445110506 nozzle component houses the DLLA138P2355 tip inside the parent injector. The Tata OE 252501160140 number on the injector body confirms the fitment.
Features & Construction
A replacement common rail injector nozzle has to reproduce the spray behaviour the engine was calibrated for. These are the design points that matter on a DLLA P-code nozzle for the 697 Turbotronn range.
Pencil DLLA P-code tip
This compatible DLLA138P2355 nozzle uses a pencil-type spray tip. The etched code DLLA138P2355 identifies the exact tip profile the 0445110506 CRI injector was calibrated with, so the ECU spray map stays consistent after rebuild.
Built to the Bosch 0433 172 specification
The nozzle is produced to the Bosch 0433 172 reference specification of the original 0 433 172 355. Spray hole count, spray angle and flow code are not published for this number, so match a coded set on a flow bench if your engine requires it.
Sealed protective pack
Each nozzle ships in a sealed protective pack so the tip is protected from contamination and static damage before fitting. Fresh fuel injector o rings (O-rings) for the parent injector should still be fitted on every job.
New, not rebuilt
This is a new nozzle rather than a rebuilt or reground exchange tip, so there is no history of wear on the needle seat. For rebuilders that standardise on new components, the part number and condition are predictable every order.
Interchange-fit for the OE codes
Designed as a compatible replacement for the 0445110506 CRI application. The common rail injector nozzle holder and the seal kit for the parent injector are sold separately so you can rebuild the surrounding fitment.
What’s in the pack
Included: 1 × new DLLA138P2355 pencil nozzle (Bosch 0433172355 reference) in a sealed protective pack, 10 pcs per box. Not included: parent injector seal kit and fuel-return O-rings — fit a fresh seal kit with every installation.
The DLLA138P2355 nozzle spray pattern is a pencil-type tip matched to the 697 engine’s combustion bowl geometry. Spray hole count and flow code are not published for this number, so confirm them on a flow bench if your build calls for a coded set.
Bad Nozzle Symptoms
Typical diesel injector nozzle symptoms include poor atomisation, hard starting, excessive smoke and rough running. Bad nozzle symptoms on a Tata 697 often overlap with rail-pressure or fuel-supply faults, so diagnose before you replace — a worn nozzle can mimic a high-pressure pump problem, and external wetness around the injector base is one warning sign to watch for.
| Symptom | What the driver or operator notices | Why the nozzle is suspected |
|---|---|---|
| Poor atomisation | Black smoke under load, unburned fuel smell, rough combustion | A worn or scored nozzle tip loses its spray pattern, leaving fuel unburned |
| Hard starting | Long cranking before firing, especially after the truck has stood overnight | A leaking nozzle needle bleeds rail pressure down when parked |
| Excessive smoke | Black smoke under load, white smoke at cold start from a dribbling tip | Poor atomisation leaves fuel unburned; a dribbling nozzle makes white smoke |
| Power loss under load | Lacks pulling power on hills, ECU may drop into limp mode | The ECU detects the weak cylinder and cuts overall fuelling to protect the engine |
| Injector knock | Diesel knock, metallic rattle or a misfire that clears at higher rpm | Timing of the injection event is off on one cylinder |
| Injector misfire | One cylinder misses, especially under load, with a stored balance code | The failing nozzle stops spraying cleanly while the others fire normally |
Bad injector nozzle symptoms start with rough idle, white smoke and a long crank. Diesel nozzle symptoms such as nozzle clogging and injector nozzle leakage let fuel leak past the tip, while injector leakage or fuel leakage at the seat raises return flow. Left unchecked, injector failure follows. What causes nozzle failure is usually carbon buildup on the tip or a worn seat, not the coil – a quick diesel injector nozzle check on the bench confirms it.
Nozzle Replacement Guide
The sequence below covers fitting a DLLA138P2355 nozzle inside the 0445110506 CRI injector on a Tata 697. High-pressure fuel systems fail when contamination enters them, so the fitting discipline matters as much as the part. Nozzle work is bench work on the injector, not in-chassis injector removal.
Diagnose and protect the system
Confirm the fault with a leak-off test and live rail pressure data before opening the injector. Work on a clean bench, cap every open line and fitting immediately, and never run the engine with the air filter or fuel filter removed. Follow the vehicle manufacturer’s filtration specification for this common rail system – replace the fuel filter and service the water separator while the system is open. If you use a diesel injector tester for the return-flow check, follow the tester manufacturer’s procedure for common rail systems.
Remove the old injector and open it
Clean the injector pocket and the surrounding area before loosening anything. Use the correct injector puller for the 697 head; a dedicated fuel injector puller or fuel injector removal tool keeps the pull axis straight, while a generic injector removal tool tends to slip – never lever against the rail or the valve cover. On the bench, release the nozzle clamp and lift the old DLLA138P2355 tip, recording the code etched on it for confirmation.
Fit new seals only
Always install a fresh injector seal kit – a new copper or steel sealing washer plus the O-rings for the parent injector. Sealing washers deform once and must not be reused, and the O-rings are single-use. Lubricate seals lightly with clean diesel or the specified assembly lubricant; keep grease away from the nozzle tip and the supplied seal ring.
Seat the new nozzle to spec
Seat the new DLLA138P2355 pencil nozzle to the parent injector’s torque value for the 697 nozzle clamp – the figure is engine-specific, so use the workshop data for the exact engine code. Over-torquing distorts the nozzle seat; under-torquing lets combustion gas leak past the tip.
Reassemble and bench-test
Reclose the injector, refit the high-pressure line and the low-pressure return. Before refitting to the engine, run a nozzle test on a common rail tester to confirm spray pattern and return flow against the spec, then crank the engine in short bursts until it fires. Watch the rebuilt injector and its connections for external leakage while it runs.
Code the injector if required
Some ECU generations store an injector coding (adjustment) value that must be written with the diagnostic tool after replacement of the parent unit. Check the service documentation for your Tata 697 / Turbotronn DICR before you start the job, and keep the code printed on the new unit to hand – if your ECU asks for it and you skip the step, the engine can run rough or log a fault even though the nozzle itself is sound.
These notes are general common rail practice, not a substitute for the Tata workshop manual for your exact engine code. Diesel injector nozzle work on high-pressure systems carries risk of serious injury – depressurise the rail before any work and use only trained personnel.
Injector installation on the 0445110506 parent must seat the new DLLA138P2355 tip to the specified clamp torque with a fresh seal ring. Torque the clamp and leak-test before the injector goes back in the head.
Warranty & Quality Policy
Every DLLA138P2355 nozzle leaves our warehouse as a new unit, in its sealed protective pack, with the standard 12-month nozzle warranty against manufacturing defects that applies across the WholesaleAutoPartsDirect range.
Manufacturing defects are covered for the 12-month term, with claims handled against the batch number; damage from contaminated fuel, incorrect fitting, water in the system or a root fault elsewhere in the fuel system is not. The full claim procedure is on the site-wide Warranty Policy page.
Because this listing supplies a new unit rather than remanufactured injectors or rebuilt injectors, there is no core exchange and no ambiguity about the history of the part. This common rail injector nozzle warranty and the component replacement warranty both cover defect claims handled against the batch number.
What the 12-month cover includes
The nozzle replacement warranty covers the DLLA138P2355 against manufacturing defects, and the injector warranty on the parent unit is handled separately by the installer. Keep the sealed pack and the order number for any claim.
