Denso Common Rail Nozzle

1. Product Introduction

A Denso common rail nozzle is a precision fuel injection component used in Denso common rail diesel injection systems.

Here’s a breakdown for you:

Function:
The nozzle is the tip of the fuel injector. Its job is to atomize the diesel fuel into a wonderful mist and spray it into the combustion chamber at extremely high pressure. This ensures better fuel-air mixing, cleaner combustion, more power, and lower emissions.

System context:
In a common rail system, fuel is stored under very high pressure in a “common rail” (a shared high-pressure accumulator) and delivered to each injector electronically. The nozzle is the final outlet where this high-pressure fuel is injected into the engine.

Design:
Denso nozzles are engineered for micron-level precision. They usually feature multiple spray holes, optimized spray angles, and hardened materials to withstand pressures often above 2,000 bar (200 MPa).

Types:

CRIN nozzles (Common Rail Injector Nozzles)– used in passenger cars, trucks, and off-road engines.
Piezo / Solenoid controlled – depending on the injector type.
Different hole sizes and patterns depending on engine requirements.

Applications:
Found in many diesel engines from brands such as Toyota, Isuzu, Hino, Ford, Hyundai, and others that utilize Denso fuel systems.
