Overview
Engine Electromagnetic Valve Actuation is a new technology based on electromagnetic actuators and control electronics instead of pure mechanical valve driving.
The general objective of the ELVAS project was to develop an improved Electromagnetic Valve Actuation System with lightweight valves and materials to reduce valve actuation power losses and be in a position to maximise fuel economy.
Funding
Results
The EU-funded ELVAS project has successfully designed, produced and tested an improved electromagnetic valve actuation system for car engines, delivering optimised fuel efficiency and reducing CO2 emissions.
In a working engine, the new system delivers:
- CO2 emissions reduced by up to 15%;
- Car engine noise reduced by up to 10dB at 3000 rpm;
- Fuel consumption reduced by up to 15%;
- Materials 100% recyclable;
- Weight savings of 25%, compared with conventional system;
- Reduced electrical consumption.
In addition, ELVAS partners have developed a new set of testing guidelines for valve actuation system components, as well as a number of new manufacturing processes.
