Product Details:

30 years in the making, AVL FIRE is the leading computational fluid dynamics (CFD) simulation package for the Internal Combustion Engine. And in the era of new drive technologies, it is a powerful tool in the development of major components in the electrified powertrain. Designed to accurately simulate relevant physics and chemistry, it has a wide range of uses. These include the prediction of fuel sprays, ignition, combustion and engine-out emissions as well as tailoring components of exhaust ...

AVL FIRE was developed to solve the most demanding flow problems in respect to geometric complexity and chemical and physical modeling. Beside all functionality that is offered in the FIRE General Purpose package, FIRE Engine comprises special capabilities and modules (as listed below) particularly designed for computing fluid flow problems related to internal combustion engines. This includes the simulation of in-cylinder phenomena such as gas exchange, fuel injection, mixture generation, combustion and emission formation, but also calculating flows in injection equipment, exhaust gas aftertreatment systems and coolant flows

AVL BOOST - Thermodynamic Cycle Calculation, High Pressure Hydraulics and Acoustic Simulation : AVL BOOST offers leading technology for the 1D simulation of gasexchange, combustion, fuel injection, duct acoustic and aftertreatment processes. It supports the design and performance optimization of all possible types of internal combustion engines at both component and system level with consistent models from concept to testing. Outstanding models for gas-phase and heterogeneous surface chemical reactions, particle loading and regeneration processes fully support the optimization of aftertreatment devices. AVL BOOST also enables the simulation of high-pressure injection systems of diesel, gasoline or alternative fuel engines based on a 1D fluid flow model and a 2D representation of mechanical parts. Moreover, it offers both nonlinear (time domain) and linear (frequency domain) approaches for the simulation of transmission losses, linear and A-weighted sound pressure levels, free field and in-duct acoustics, intake and/or exhaust orifice noise.
AVL FIRE - CFD for Engines : AVL FIRE is a powerful multi-purpose 3D CFD software with a particular focus on and strength in handling fluid flow applications related to internal combustion engines and powertrains. The tool reflects the latest achievements with regard to grid generation and solver technology, physical and chemical models. AVL FIREs technological leadership with respect to modeling fuel injection, air/fuel mixture preparation, wallfilm, ignition, flame propagation and pollutant formation is recognized worldwide. 
AVL CRUISE - Vehicle System Simulation : AVL CRUISE efficiently solves everyday tasks with respect to finding the right balance between fuel economy, emissions, vehicle performance and drive quality throughout all development phases, from concept planning through to testing. The flexibility to model any kind of powertrain configuration, from conventional and hybrid to the most innovative ones, is extended with open interfaces to leading 3rd party simulation products and real-time validation platforms. An advanced sub-system integration concept and consistent data and model management make AVL CRUISE the tool of choice.
AVL EXCITE  Durability and NVH of Power Units and Drivelines : Using advanced modelling techniques, AVL EXCITE calculates the dynamics, strength, vibration and acoustics of combustion engines, transmissions, conventional and electrified powertrains and drivelines under real operating conditions. Sophisticated models for lubricated sliding contacts (slider bearings, piston and piston ring / liner contact) support the design analysis of these engine components by enabling the detailed investigation of key functions such as friction, wear, performance and durability. Different modelling levels for single components, subsystems and entire systems help the engineer to use an optimum balance of model depth in terms of required accuracy for the application target and the modelling and simulation effort

AVL EVSuite - Simulation Solutions for Electrified Powertrains : The AVL eSUITE offers flexible, fully integrated simulation solutions for electrified powertrains and vehicles. These include concept and layout investigations, as well as optimization and integration tasks from a system level to detailed 3D component analysis.

AVL BOOST - Boost is a 1D thermodynamic based simulation software which is used during the concept stage of engine development. With Boost various engine performance parameters can be simulated like emission, fuel consumption, power, torque etc. Boost has different modules which deals
with engine combustion, linear & nonlinear acoustic & exhaust gas aftertreatment analysis

BOOST is a simulation Program specifically developed for the modeling of a complete engine. The code can simulate the entire engine cycle including combustion.

BOOST was created within AVL''''s department for applied thermodynamics. The task of engine analysis using thermodynamic measurements and calculations is of special importance. This is because it constitutes the base from which the knowledge of how to model an engine is acquired and is a
prerequisite for performing other tasks

The intuitive BOOST GUI enables users with basic knowledge of engine cycle simulation techniques to take full advantage of all capabilities within a short period of time. Even novice users are in a position to solve simple problems after a brief training period

Battery & Fuell Cell - Vehicle Development Software -

Fuel cell electric vehicles (FCEV) are an attractive, clean alternative to conventional internal combustion engine vehicles (ICEV). Delivering performance comparable to ICE-based powertrains, balanced with emission-free driving, they offer a range of benefits to the end user. Long driving ranges and fast refueling make proton exchange membrane (PEM) fuel cells viable for both passenger cars and light and heavy-duty commercial vehicles, too.

At AVL we have developed a portfolio of powerful simulation tools to optimize the fuel cell system. AVL eSUITE helps OEMs and suppliers get the best performance and longest lifespan from this clean power source.

New Technology, New Challenges

To ensure the optimum performance of any fuel cell system, an integrated approach to development is vital. Scalable system simulation allows analysis of the cell and stack as well as the layout of the balance of plant (BoP) and coolant circuit subsystems.

The ability to conduct in-depth investigations into the behavior of components and systems - both individually and in concert - aids the development of tailored operating strategies. Furthermore, detailed multi-physics modeling supports the understanding of ion flow, chemical reactions and water transport.

New Solutions

Improving performance and extending system lifespan, the eSUITE simulation tools enable OEMs to optimize concept layout, component size and their overall operation strategy. From cooling concept definition and specification to component and system control function strategy evaluation, this approach delivers insights that support fuel cell innovation.

eSUITE combines powerful products such as AVL FIRE M and AVL CRUISE M. It offers an unmatched solution for fuel cell, stack and system development as well as vehicle integration tasks during all phases of the development process.

AVL eSUITE can help you gain the performance your users demand from your fuel cell systems. Our experience and solutions make us the preferred partner for OEMs and suppliers alike, when it comes to meeting targets for a cleaner, sustainable future.
