Thermal engine
Since its creation, Sherpa Engineering is involved in the activities of design and validation of powertrain applications for automobiles and trucks.
|
SHERPA ACTIVITIES
-
Dynamic modelling of powertrains conform to norm Euro 3,4,5,6
• diesel supercharged single or multi-injection
• manual box, robotized or automatic
|
 |
STUDIES
-
consumption and pollution during dynamic cycles, hot and cold engine
-
development of control laws for engines and gear boxes based on modelling technologies
-
data analysis, coherence analysis and estimation of the engine parameters
-
diagnosis : diagnosis of the engine health
|
 |
-
Validation and closed loop testing (controller model + physical model) for each phase of the cycle
|
 |
PRODUCTS
|
From its expertise in modeling and control, Sherpa has developed a platform for simulation and validation tools.
These tools support the life cycle of drive-train (engine, gearbox, steering system, sensors and actuators).

Caracteristics of the models :
-
modular, based on physical properties
-
accurate models for steady state and transient responses
-
Reduction of the time spent on configuration thanks to pre-processing : parametrization, configuration, open and closed loop simulation, post-processing

Description of the model
-
Basic model : it represents all kinds of engine architectures (diesel, gasoline or gas) with or without turbocharger.
-
Library of models : Sherpa refers to methodologies PhiGraph© and PhiSim©
-
Module for engine cooling (Add on) : includes thermal effects (water, oil, air) and their links with the engine
-
Combustion Module (Add on) : gathers combustion and coupling with the thermo-fluid and mechanics. This module includes pollutants calculation
-
Fuel system (Add on) for fuel injection (single ou multi-injections)
-
Control Module (Add on) : this simplified module includes the actuators of the air and fuel circuits (EGR, Turbo, VVT,...). It represents the strategies and operating modes : ralenti, coupure d’injection.
-
Post-processing module (Add on) : représente chemical effects inside the systems DPF, catalyst and SCR.
-
Utilities : Module for calibration, parametrization and validation
