WAUKESHA* CFR* FUEL IGNITION TESTING FOR DERIVED CETANE NUMBER OF DIESEL FUELS

Product catalog summary

Introduction to FIT
The Fuel Ignition Tester (FIT) is a compact, economical instrument designed to measure the ignition delay of diesel fuels and determine their Derived Cetane Number (DCN). It serves as an alternative to the traditional CFR Diesel Cetane Rating Engine, offering ease of use, low maintenance, and high throughput.

Specifications and Design
The FIT unit features a Constant Volume Combustion Chamber (CVCC) and operates under ASTM D 7170-06 and IP PM-DI/06 test methods. It requires simple calibration using n-Heptane and Methylcyclohexane. The unit is compact, easy to install, and integrates with Microsoft® Windows® systems for data management.

Installation and Operation
Installation involves connecting to pressurized air, cooling water, and a computer. The FIT is user-friendly, with automatic operation initiated via a computer interface. It requires no fuel mixing, reducing errors and costs.

Testing Capabilities
The FIT can test diesel fuels with cetane numbers ranging from 30 to 80, including bio-diesel and blends. It provides results with a repeatability of 0.7 DCN and a test cycle of 20 minutes.

Accuracy and Precision
The FIT offers high accuracy, minimizing cetane giveaway and accurately assessing cetane improvers' effects. Precision is supported by a factory calibration curve, reducing setup time and operator error.

Components and Requirements
The FIT includes a diesel fuel ignition test unit, circulation chiller, air reservoir, and sensor shim kit. It requires a 220V power supply, specific air and exhaust connections, and a cooling water bath.

Conclusion
The FIT is a reliable tool for quality control and research in diesel fuel combustion, providing quick, accurate, and repeatable results.
