Latest release: (June 2020) has 3D mesh for sprays spatial intersection analysis; supports dual fuel engines, engines having few (up to 5) fuel injection systems working independently and injecting different fuels in one cycle; Finite Element Analysis of engine parts temperatures (What is a Diesel-RK.pdf).

The Engine Analyzer lets you simulate an engine build-up or modification on your personal computer. It let's you play 'what if' with cams, Heads, intakes, Superchargers, etc. And see the effect on torque, HP, fuel flow, air flow, valve toss or lifter pump-up, idle vacuum, cranking compression, spark knock, etc. 'Its like having a dynamometer right in your computer.' Lotus Engine Simulation. The engine model, designed with LESoft, is shown in Figure 7. The engine model consists of the cylinder (“CYL1” element), and intake and exhaust networks each of which is designed using three elements representing connector, port, and valve. Technical Overview: Dynomation-5 incorporates two distinct engine simulation models: 1) A Filling-And-Emptying simulation that provides extremely fast mathematical solutions to engine physics, including flow analysis and common intake- and exhaust-manifold modeling, making this technique a uniquely powerful and rapid way to 'ballpark' engine.

DIESEL-RK is a new generation of engine simulation software DIESEL intended for ICE analysis. Diesel-RK code allows simulation and optimization of mixture formation and combustion in diesel engines. Spatial visualization of fuel sprays evolution helps to design piston bowl shape and sprayer nozzles orientations. NO emission model uses Zeldovich's mechanism for conventional engines and Detailed Kinetic Mechanism with zone model of combustion for modern engines having large EGR and multiple injection. Soot emission model is realized. Modeling of combustion with multiple fuel injection with electronically controlled fuel injection system allows development a Common Rail control algorithm. Thermodynamic model provides turbocharger and supercharger matching using SAE format files with turbine and compressor maps, EGR and bypasses simulation. Thermodynamic analysis and multiparametric optimization of valve timing, in-cylinder parameters, fuel injection system are provided. Remote access via Internet is supported. For simultaneous optimization of few engine parameters: NOx, Soot and SFC the target function including list of engine parameters may be calculated with User Model DLL and linked to the existing DIESEL-RK kernel. Detail Chemistry simulation at Ignition delay prediction for diesel fuel and Bio-fuel is implemented for PCCI and HCCI analysis. Results obtained with CHEMKIN code are used. Gas engines fueled by any kind of gas including natural gas, pipeline gas, biogas, syngas and arbitrary mixtures of gases are supported. Download software for free ...
