Show Review 2019

2019 show sees successful rebranding and addition of two new conferences

2019 saw the 21st edition of a freshly rebranded Engine Expo + The Powertrain Technology Show return once again to the Stuttgart Messe, combining an exciting array of engine and powertrain technology launches from a diverse range of international exhibitors with two brand-new conferences: The Path Towards Euro 7 and The Powertrain Testing Conference.

From starter-generator-based mild-hybrid systems through to true hybrids, to fully electric and fuel cell vehicles, the range of powertrains on offer today encompasses much more than just ‘engines’ – and the breadth of technology on display at the show reflected this.


Meanwhile Aumet displayed its Z-engine powertrain model – an intelligent engine that uses single-fuel RCCI combustion. The system controls the ignition point to achieve the greatest efficiency and avoids too high a pressure in the cylinder. The result is a lean air-fuel mixture, containing both IEGR – for rapid fuel evaporation – and LPEGR, which contains steam that can be condensed and injected to the intake ports to control the TDC temperature. The company claims the engine offers 20% lower manufacturing costs and 20% lower weight, while remaining compatible with regular car industry components.

Exciting innovations included everything from the latest high-tech forced induction solutions from Van Der Lee Turbo Systems, through to advanced prototyping technology from AC Tech; and brand-new techniques in metal injection molding from MIMplus to leading insulation breakthroughs from Nipass, and state-of-the-art casting from Hitchiner.

Nostrum was in Stuttgart to demonstrate a sophisticated water injection system: the system provides knock mitigation, octane on demand and NOX management, and can be used in performance, efficiency or commercial engine applications. The vehicle-integrated injection system relies on a standalone controller allowing full flexibility in firing events, which can be tied to the fuel injectors or operated by more a conventional crank angle-based injection control strategy.

“The system enables the delivery of octane on demand to the engine by injecting water, enabling the performance envelope of the engine on regular fuel to be raised,” explained Nostrum’s director of engineering, Sam Barros.

A number of new solutions on display were specifically tailored for engine electrification. For example, Industrie Saleri presented a dual-mode electromechanical water pump that is able to operate in electrical mode for 95% of its life. “The key with this water pump is that it can function both mechanically and electronically, depending on the conditions of the engine,” said Annalisa Reboldi, communications specialist, Industrie Saleri Italo.
