Powertrain Design - Large Engines

A competitive economic environment and increasingly stringent emission regulations are the main drivers for optimizing the efficiency of large engines in marine, power generation, construction and other areas. Fuel efficiency, initial cost, reliability and service/maintenance life cycle cost are key considerations for the creation of optimum engine performance perfectly tuned to the customer's needs. The newest technologies for aftertreatment, waste heat recovery, auxiliary drives and cooling systems are as important as the expertise of the engineering partner. AVL has the most experienced design engineering team for the development and optimization of large engines (diesel/natural gas/dual fuel). Close collaboration through worldwide presence, technology innovation, simulation-based and production-oriented development, modern testing facilities and system integration are all expressions of AVL's technical competence and global expertise.
