Browser-native tools for engine thermodynamics, fuel spray dynamics, and EV battery modeling.
Research-grade combustion software built for researchers and engineers.
A transient 0-D solver — 2,881 equations at 0.25° crank-angle resolution, sub-20 ms per cycle. 12+ fuel models. Knock, NOₓ, P-V diagrams. In your browser. Free.
Droplet SMD, spray penetration, cone angle, and D² evaporation — without a wind tunnel. Export CSV + SVG.
ECM modeling, SOC/SOH estimation, thermal coupling, CC-CV charging, and degradation analysis — 6+ chemistries.
Reynolds, y⁺, turbulence properties, and non-dimensional numbers — four browser tools, instant results.
Structured courses by an active combustion researcher. CONVERGE, GT-Power, HPC — real workflows, not toy tutorials.
Every result traces back to published, peer-reviewed equations — the same ones used in combustion research labs. Nothing here is a hand-wavy approximation.
x_b through the engine cycle. a and m are shape factors fit to real cylinder-pressure data — this is the same function used in GT-Power and CONVERGE for 0-D/1-D combustion modeling.
AgniCycle's simulator solves this across 2,881 discrete crank-angle steps per cycle, coupled to a full first-law energy balance on the cylinder control volume. The thermodynamic property models trace to peer-reviewed combustion literature for diesel, gasoline, and alternative fuels.
It's a 0-D tool — fast enough to run instantly in your browser, accurate enough to use as a baseline before committing to a multi-hour 3-D CFD run.
Three very different people open AgniCycle every week — each one comes for something else.
Agni — the classical Sanskrit word for fire and ignition. Cycle — the continuous thermodynamic loop at the heart of every engine. Together: a platform built to model the controlled burn that powers our world.
Our mission is to make research-grade simulation accessible — so every combustion engineer, not just those with institutional software licenses, can push alternative fuels to their thermodynamic limits and accelerate the path to clean propulsion.
AgniCycle tools are built and maintained by active researchers. The physics you interact with is the same physics used in daily research — not a simplified demo.
Everything you need to know about AgniCycle tools and the physics behind them.
