Engine calibration methods & tools

Tougher legislation, increasing system complexities and tighter budget and resource pressures have driven the requirement for efficient and cost effective engine and vehicle calibration methods and tools that support the whole development cycle from concept through to production.

Our Approach

In response to these challenges MAHLE Powertrain has developed CalLogiq; an integrated approach to engine and vehicle calibration. CalLogiq incorporates:

• MAHLE Powertrain's extensive knowledge base which feeds into experience driven calibration approaches and toolsets
• Efficient resource utilisation ensuring data and knowledge are exchanged efficiently between all activities
• Continuous monitoring against clearly defined quality targets (Measures of Success)
• Advanced data management and analysis
• Validation, using ProLogiq™ incorporated at an early stage in a project to ensure all concerns are identified quickly and resolutions validated prior to Start of Production (SOP)

Our Tools, Facilities and Services

With a global network of offices and test facilities, MAHLE Powertrain is positioned to provide local support and expertise in North America, Brazil, China and Europe. We cover calibration activities for gasoline and diesel products from concept to production in the following areas:

• Concept demonstration including rapid development of prototype vehicles
• Software development using MAHLE Powertrain's Flexible ECU platform
• Thermodynamic engine development
• Engine mapping
• Exhaust aftertreatment specification and emissions calibration
• On board diagnostic (OBD) calibration
• Benchmarking
• Engine and vehicle validation using ProLogiq™
• Certification, master proving and Production Vehicle Evaluation (PVE) testing

Customer Benefits

CalLogiq provides a target driven calibration process that is fully flexible and can be tailored to any customer requirements. Using MAHLE Powertrain to support your engine and vehicle programmes will lead to:

• Enhanced product quality leading to a reduction in warranty claims
• Reduced costs and improved timescales achieved by efficient resource utilisation and advanced by efficient resource utilisation and advanced data management and analysis techniques. Overall there is a requirement for less resource, fewer engines and fewer vehicles.

Project Examples

CalLogiq provides an integrated calibration approach that can be applied to any project phase from concept to production. The following provide recent examples.

• High performance sports car demonstrator with a V8 turbo MPI engine to Euro 5 emissions levels
• Full OBD calibration to Euro 5 and Ultra Low Emissions Vehicle 2 (ULEVII) across a range of engines and vehicle platforms
• Fleet validation for OBD and In Use Monitor Performance Ratio (IUMPR) in USA and Europe for several major OEM's using ProLogiq™
