The DIESEL-RK is professional thermodynamic full-cycle engine simulation software. This tool covers wide range of practice tasks: from general multicylinder engine concept analysis up to design of engine systems. The kernel of DIESEL-RK includes gas-exchange model, heat-exchange in engine elements, turbocharging, EGR, friction, water condensation, etc. (everything for full cycle simulation). DIESEL-RK is focused on advanced diesel combustion simulation and on emission formation prediction. The main features of DIESEL-RK are below, see details in What is a Diesel-RK.pdf as well.

• Thermodynamic analysis of Diesels fuelled by diesel oil, methanol, bio-fuels and mixtures of bio fuels with diesel oil. HCCI / PCCI concepts and Dual fuel systems are supported.
• Thermodynamic analysis of SI petrol engines and gas engines, including prechamber engines, and engines fuelled by Natural gas (Methane), Pipeline gas (Propane-Butane), Biogas, Wood gas, Syngas with arbitrary composition (Producer gas), etc.
• Water injection with account of H2O condensation and evaporation in intake manifold, port, cylinder.
• Thermodynamic analysis of Two- and Four-stroke engines; Junkers OP engines; Crank case scavenged engines, etc.
• Simulation and optimization of Mixture Formation and Combustion in diesels.
  • Fuel Injection optimization. Optimization of sprayer design and location. Optimization of injection pressure, injection timing, injection rate shaping, split / multiple injection strategy. Individual diameters and arbitrary orientation of each nozzle are supported.
  • PCCI analysis including Low Temperature Combustion phase, etc.
  • Few injectors in one cylinder may have independent control (own fuel and own injection profiles). This system may be optimized.
  • Detail Chemistry is simulated for Ignition Delay prediction at PCCI and HCCI for Diesel Fuel, Methanol and for Bio-Fuel.

Latest release: 5.3.9.78 (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).

This project has been supported by EU Marie-Curie International Incoming Fellowship Grant FP7-PEOPLE-2012-IIF/PIIF-GA-2012-328361.

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 ...
