Large Engines

AVL aims to be the industry's preferred partner throughout the entire life cycle of large engine products – from strategy all the way through to production and field operation.

Products & Services

Powertrain Design

Sustainable and clean powertrains require the permanent design improvement of the traditional IC engine. Due to the increasing complexity between the interrelation of the IC engine, transmission, electric motor, battery and controls, a comprehensive development approach is also required to deliver market-tailored, competitive powertrain solutions on schedule.

NVH Engineering for Large Engines

Mainly vibrations are the big topic for large engines. Especially for singly cylinder setups the testing layout has to be designed carefully to allow operation over the complete targeted engine speed range without running into resonances. Additionally NVH could be used for monitoring large engines and detect necessary maintenance before the engine is damaged.

Combustion and Emissions Simulation

AVL BOOST and AVL FIRE® are the industry's first choice when reliable results are needed for engine thermodynamics and combustion/emissions development. The intelligent integration of the two software tools facilitates solutions for complex tasks early in the development phase and provides unsurpassable accuracy during the detailed design phase.

Emission Certification

Emission Regulation is moving forward. Euro 6 has arrived in Europe, 40CFR1065 and 40CFR1066 in the US as well as the new Worldwide Light Duty Test Procedure has been published as Global technical regulation. And more challenges to come for the different applications. Measuring hybrid powertrains with their complexity, new measurement methods, changed procedures and real driving emissions are just a few examples.

Performance and Emission Development

Today, the development of engines is increasingly challenged by the requirement to meet future stringent emission legislation while satisfying the end-user's demand for improved operating efficiency and fuel economy. Apart from that, end-users are generally asking for permanent increase of engine performance. This requires continuous improvement of existing powertrains and the development of new engine generations. AVL offers the complete powertrain development services starting from design...

Injection Nozzle Development

AVL FIRE® offers unique capabilities for analyzing and optimizing injection nozzles in respect of transient discharge rates, the occurrence of cavitation and potentially occurring material erosion.

Mechanical Development and Validation

AVL offers mechanical testing for the verification and validation of engines, transmissions, exhaust gas aftertreatment and hybrid systems. Mechanical development activities cover all areas from component testing and engine testbeds, right up to full vehicle validation.

Analysis and Simulation/CAE

Simulation has become a key enabling factor in the development of highly competitive and advanced powertrain systems. CAE methods play a vital role in defining new powertrain concepts from hybrid to pure electric vehicles.

Simulation for Strength and Durability Analysis

In order to achieve the aim of reducing weight for better performance and lower fuel consumption, component engineering of engines and powertrains continues to approach the limits of strength and durability.
