Powertrain Engineering

ESimLab is an expert partner to the automotive and mobility industry for the development of innovative powertrain systems. The need for CO₂ reduction, the increasing complexity of new powertrain systems, and a requirement to achieve the highest possible level of process efficiency – along with the need to quickly launch new models – are some of the key challenges facing the automotive industry now and for the foreseeable future.

From diesel engines to electric drives, from alternative fuels to control, from transmissions to batteries, we have been working to design and optimize new challenging process to obtain new standards criteria and even more than it. Unique synergies with ESimLab experience and combination of Advanced Simulation Technologies enable the development of highly creative, mature and application-specific solutions to enable our customers to meet their future market challenges.

ESimLab offers best software solution and combination of the solutions, features and validated simulation methods dedicated to combustion system and engine component development, enabling superior engine performance.

NVH & Acoustics for Powertrain

The global demand for more eco-friendly vehicles compels automotive OEMs and suppliers to develop fuel-efficient internal combustion engines. While fuel economy measures positively impact the emission of greenhouse gasses, it inevitably affects the vehicle’s noise, vibration and harshness (NVH) and acoustic behavior.

Weight reduction and downsized turbocharged engines might increase torsional excitation causing low frequency driveline NVH issues when integrating the driveline into the vehicle. In addition, new energy management systems such as cylinder deactivation systems and start-stop systems can cause new transient NVH phenomena. These new complex NVH issues need to be addressed on top of the typical engine-related NVH topics, such as engine radiation, gearbox rattle, whine, judder, clunk, fuel slosh, intake and exhaust noise, and auxiliary noises.

With advanced Multi-Body Dynamics (MBD) in coupled with CFD and FEA packages, ESimLab help manufacturers save time and cost to diagnose, analyze and resolve driveline NVH and drivability issues while balancing fuel economy, drivability, NVH and ride comfort, and increasing the efficiency of the NVH development process by using advanced specialized packages like AVL and Ricardo.

Flow, Combustion and Emission

1D-3D coupling are the industry’s first choice when reliable results are needed for engine thermodynamics and combustion/emissions development. The intelligent integration of these two software tools facilitates solutions for complex tasks early in the development phase and provides unparalleled accuracy during the detailed design phase by global CAE leaders. With 1D-3D coupling, we deliver a solution dedicated to solving specific tasks related to Internal Combustion Engine (ICE) development, such as matching performance requirements, lowering fuel consumption, emissions, CO2 and optimizing the engines thermal management.

Thermal & Energy Management

he overall complexity of the powertrain has significantly increased with the need to understand the detailed interaction of the individual sub-systems across a range of attributes. Improving fuel economy while reducing pollutant emissions implies deep engineering investigation to optimize powertrain energy management strategies, and ultimately how it impacts vehicle performance.

ESimLab proposes a full-vehicle simulation approach provided by  3D CFD simulation tools, along with our engineering services capabilities, to enable full traceability of powertrain energy balance. Being able to have complete understanding of transmission performance and losses, engine air intake and in-cylinder combustion, engine thermal management strategies and the impact of all these subsystems choices on the global vehicle performance during integration is crucial.

Strength and Durability Analysis

In order to achieve the aim of reducing weight for better performance and lower fuel consumption, component engineering of engines and powertrains continues to approach the limits of strength and durability. 

By combination of best in class CAE package, ESimLab propose best solution for strength and durability analysis with various modeling depth levels ensuring accuracy according to stage in the development process. The solution comprises the whole analysis workflow from dynamic analysis of subsystems and entire powertrains up to stress and fatigue strength evaluation of powertrain components, Outstanding models of lubricated contacts (slider bearings, piston and piston rings) facilitate detailed investigations of the contact behavior, including the prediction of friction and wear.

Turbocharging Simulation

Turbocharging allows automakers to reduce engine size and emissions while continuing to deliver the power and performance consumers demand. To improve overall engine performance, reduce pollutant formation, optimize NVH and ensure component durability, ESimLab combine advanced simulation tools offer exactly what is needed to design advanced pressure charging systems.

Our offering includes:

  • Aerodynamically develop and optimize turbine and compressor wheels for highly efficient charging devices
  • Design new turbochargers with engine matching at every design step
  • Change compressor and turbine sizes and predict the effect of these changes
  • Ensure best NVH behavior and maximum durability
  • Optimize Rotor Dynamics

ESimLab use combination of advanced Finite Element Tools to investigates the dynamic stability of the rotor bearing system. The multi-body dynamic solution includes non-linear models to detect critical speeds and analyze the influence of full or semi-floating bushing configurations. For investigate and Minimize the Thermal Loads, ESimLab use advanced CFD Tools for fast rotating systems to prediction of the thermal load of the turbine and compressor wheels as well as the turbocharger housing.

Injection Nozzle Development

ESimLab use combination of advanced CFD Tools to the development and optimization of injection nozzles. With combination of a one-dimensional model typically represents the complete injection system from the fuel tank to the injector, 3D CFD Solver focuses on the three-dimensional calculation of the fluid flow inside the injection nozzle. 

This simulation capabilities enable virtual design of: Reduce cavitation and avoid erosion in injection nozzles Achieve higher engine-out performance and lower engine-out emissions Performance Counts. In an early engine design stage, fuel injection details, such as needle lift and inlet pressure level, are not known. Thus, a virtual prototyping environment, consisting of 1D and 3D fuel injection simulations is extremely valuable.

To get the maximum benefit out of 1D-3D coupling, models coupled in a co-simulation, with 3D CFD Model providing pressure forces on the injector needle and 1D model computing longitudinal and radial needle motion based on this information. This allows to calculate discharge rates more accurately and to precisely predict cavitation and erosion.

Simulation for Quenching: Virtual Heat Treatment Optimization​

Quenching is used in the production of cast or otherwise-produced metal components. In particular, immersion or direct quenching processes are widely adopted procedures in the automotive and aerospace industries to minimize the formation of undesirable thermal and transformational gradients, which may lead to increased distortion and cracking. The proposed method for simulation must accurately predict real-time quenching effects, local temperature gradients and the overall cooling history of complex quenched components.
