FP7 green cars initiative project

Proposal full title: Libralato Engine Prototype
Proposal acronym: LIBRALATO
Work programme topics addressed:
GC.SST.2010.7-3. Optimised thermal engine development and integration

New engine designs are required which meet the demands of Hybrid Electric Vehicles (HEV) and Plug In Hybrid Electric Vehicles (PHEV):-

  • aggressively downsized and integrated within series or parallel hybrid electric vehicles;
  • designed for 'steady state' operation within their BSFC peak efficiency zone;
  • exceeding Euro 6 emissions standards;
  • with reduced production and maintenance costs,
  • with exceptionally low NVH behaviour;
  • with compact proportions that can be easily integrated within vehicles.

Name Improvement over current technology status Benchmark How measured
Production cost 30% Toyota Prius 1.8L 2ZR-FXE Using estimates prepared by the IAG and comparing with published data on the Toyota engine
Size 50% Toyota Prius 1.8L 2ZR-FXE Measured in litres/kW; based on manufacturing predictions
Weight 50% Toyota Prius 1.8L 2ZR-FXE Measured in kg/kW; based on manufacturing predictions
Thermodynamic efficiency Improvement to 39%; (30% over current technology) Toyota Prius 1.8L 2ZR-FXE and Revetec engines At least 39%, measured during hot tests using laboratory instrumentation
Exhaust emissions Significant improvement over Euro 6 25% HC and particulate matter; 25% NOx Measured during hot tests using normal laboratory instrumentation
Packaging effectiveness Demands less packaging volume by 25% Smartfortwo Will accommodate a hybrid configuration with a 25% margin over a current technology solution
