Internal Combustion Engine Related Hydraulics

LMS Imagine.Lab Internal Combustion Engine Related Hydraulics helps design and optimize fuel systems and components from tank to injector. It further assists in designing valve actuation systems in relation to the engine cylinder:

Injection Systems
-     Gasoline, diesel and alternative fuels: DME, LPG, CNG
-     Low and high-pressure injection systems
-     Indirect/direct injection, common rail, unit injector, in-line pump
-     Solenoid, piezo, electro-hydraulic valve or mechanical actuation
Valvetrain
-     Variable valve timing and cam phasing
-     Variable valve actuation with mechanical (MVT), electro-mechanical (EMVT) or electro-hydraulic (EHVT) systems
-     Engine compression brake
-     Camless systems

LMS Imagine.Lab Internal Combustion Engine Related Hydraulics is based on the LMS Imagine.Lab AMESim multi-domain system simulation approach and helps develop new concepts to confront challenges posed in systems such as high pressure multiple injections, gasoline direct injection, return-less low pressure gasoline systems, variable valvetrain and engine compression brake systems. The solution comes with a large and flexible set of models, addressing different complexity levels (leakage, compressibility, stiffness, inertias, friction...).

The accessibility, solver efficiency and accuracy of the models help both specialist and non-specialist engineers to design robust systems while keeping costs and delays under control.

Features

Hydraulic component design: Morphologic approach to model components based on geometrical data, focusing on physical effects, like energy exchange
Advanced analysis tools: linear analysis, design exploration, activity index
Connection of subsystems

Benefits

Accurate description of fast fluid dynamics physics
Study any kind of environment, from very low-pressure (cavitations) to very high pressure (>2000 bar)
Easily couple subsystems components for global system analysis
Accurately predict injection and valve lift flow rates for different operating conditions

Covering a range of industries, LMS application cases let you discover how LMS solutions help our customers solve their real-life engineering challenges.

diesel engines modeling design software 3.gif Delphi cuts next-generation diesel engines ECU development time with LMS Imagine.Lab AMESim

Working together with LMS Imagine.Lab engineering services, Delphi engineers use LMS Imagine.Lab AMESim multi-domain system modeling software to efficiently develop advanced HiL simulators to design and test electronic control units for tomorrow’s fuel-efficient, clean-running diesel engines.

Messier-Bugatti optimized the A380 nosewheel steering and braking system with LMS Imagine.Lab AMESim

To save weight on the A380 superjumbo aircraft, Messier-Bugatti used LMS Imagine.Lab AMESim and the Ground Loads solution to design an innovative decentralized hydraulic generation system with lightweight micro-pumps delivering power locally to emergency braking and landing gear steering systems.

Renault applies AMESim to streamline its cooling and air-conditioning systems development process

To comply with the multiple constraints relative to vehicle designs that affect the thermal management of underhood systems, and to ensure high-quality passenger comfort, Renault decided to rely more on simulation to engineer the underhood thermal environment. The French car maker deployed the AMESim solution as a collaborative system simulation platform.
