“Combining physico-chemical simulation…

SRM Engine Suite

kinetics

Robust simulation of IC engines

Reactor models, fuel models, emissions pathways

Parameter estimation, sensitivity analysis and uncertainty propagation

Surrogates, data-driven model generation and Design of Experiments (DoE)

…with advanced statistical algorithms”

Motivation

• Data heterogeneity– Customers: Extensive non-standardised data– Gaps, errors and uncertainties related to the data– Inconsistent data formats

• Differences in vocabulary: – Data channel names – Models vs. numerical methods– Variables (e.g. inputs, outputs) vs. parameters (model, numerical)

• The size of the evolving data, the heterogeneities and the inconsistencies inflict a cost on robust and systematic model development and application

• Ontology, a key part of the overall solution: formal, explicit specification of a shared conceptualisation

Engine operating window

4.4l Turbocharged Aftercooled (TA) Tier 4 capable IC engine

• Background & objective– CAT 4.4 IC engine used in multiple machines/applications: agriculture,

construction, cranes, loaders, etc. – Engines designed to meet stringent emissions regulations

– To develop and apply an integrated workflow combining physico-chemical and statistical models to augment the measurements data

– Data heterogeneity and evolution are the main drivers for standardisation

Methodology

Store – timeless, accessible data

Manipulate – control, manage your data

Use – visualise and understand

Build – Build models on top of the data

Optimise – Model parameter estimation

Validate – Compare with experiments

Run –predictive/parametric studies

engineML

• Consistent format

• point data (e.g. rpm, CO, ul) • time resolved data (p-CA)• Apparatus (production engine, research engine)• errors• data type (consistent units)• raw or processed

• XML code selected

machine and human readable tree structure validated against schema

• Easily accessible database

read by model code data stored consistently old data never forgotten

General data

Case data

Particulate matter (PM) emissions

• Soot emissions:

Dsoot g A mps phi

SAE 2010-01-0152

Friction

• Statistical/data-driven analysis to produce a hierarchy of models

• Compare the performance of all models as a function of:• Choice of the objective function• Training, verification and

validation methodologies

• Final recommendation – model ranking based on technical criteria such as error measures and CPU expense.

Eco-industrial park (EIP)

Jurong Industrial Park (Singapore)

A cluster of businesses that collaborate with each other and the localcommunity to efficiently share resources, and to reduce waste and pollution.

OntoCAPE

A general-purpose ontology for applications in the domain of Computer-AidedProcess Engineering (CAPE) was adopted and extended

Extendable(can be extended to other domains: Electrical engineering, Transportation)

Specific application(chemical processes)

Biodiesel plant representation in OWL

① - IRI for biodiesel plant; ② - IRI for the surrogate model, through which its executable model (⑤) and name

information (⑥) can be extracted.③ - IRI for the mathematical programming model, through which, the GAMS code

(⑨) can be extracted.④ - IRI of the subsystems (unit operations).
