See the AgniCycle Engine Simulator take a first engine estimate from setup to results in seconds, right in the browser.
Research-grade combustion software built for researchers and engineers.
A transient 0-D solver with crank-angle steps down to 0.25°. Explore 12+ fuel models, pressure traces, P-V diagrams, and knock and NOₓ estimates. Free during beta for approved users.
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.
Explore established combustion models with adjustable inputs. Published model equations provide a foundation; accuracy depends on the assumptions, calibration, and operating conditions.
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 crank-angle samples at the finest 0.25° setting over a 720° 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.
Use this 0-D tool for teaching, parametric exploration, and preliminary screening. Check predictions against experimental data for your engine before drawing research or design conclusions.
Explore bulk cylinder pressure, temperature, heat release, and cycle performance. Spatial flow, flame structure, and local mixture variations require additional models.
Fuel properties, heat transfer, and combustion timing affect predictions. Knock and NOₓ outputs are model estimates; compare them with measurements within your operating range.
Report the tool version, inputs, crank-angle resolution, and assumptions. Compare predictions with experimental data and quantify error for your case.

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.
