Introducing IQT-FLEX: Unlocking Research Freedom

To fully support the scientific community, the IQT brand has launched the IQT-FLEX — a purpose-built research configuration designed as a software upgrade to the standard IQT-XLM system.

With IQT-FLEX, laboratories can seamlessly switch between standard compliance mode and research mode, enabling both regulated DCN testing and advanced combustion experimentation within a single hardware platform.

This dual-mode approach provides unmatched cost-efficiency for universities and innovation labs, eliminating the need to operate separate instruments for certification and scientific discovery.

The IQT®-FLEX unit is specified equipment for testing fuels according to:

ASTM D6890:

Standard Test Method for Determination of Ignition Delay and Derived Cetane Number (DCN) of Diesel Fuel Oils by Combustion in a Constant Volume Chamber

Flexibility Shifting Between Modes

The IQT-FLEX is available as an add-on software upgrade for current IQT-XLM units with the ability to switch back and forth between research and standard testing modes.

Expandable Upgrades & Design

Upgrades such as longer ignition delays, unusual test conditions, and flexible test design are provided with the IQT-FLEX application.

Additionally, the IQT-FLEX application allows for easy variation of key combustion parameters (temperature and pressures), with full associated data capture of the combustion event and trace.

Key Capabilities

Change air pressure up to 375 psi

Combustion chamber temperatures up to 750°C

Ignition delays up to 600 ms for challenging low-reactivity fuels

User-configurable injection profiles (pre-injection, main, timing, duration)

Non-standard calibration curves for developmental fuels

Full-cycle pressure trace capture for every combustion event

Your Key to New Fuel Development

The IQT-FLEX dramatically expands operating capabilities and user control, delivering a research platform engineered specifically for studying fuel formulation, combustion kinetics, low-temperature ignition chemistry, and alternative combustion regimes. More importantly, the IQT-FLEX enables researchers to evaluate how real-world engine parameters affect ignition delay and combustion phasing — insights essential to accelerating new fuel development.
