First MCE-5 VCRi Vehicle To Be Unveiled in Geneva Motor Show
Among the highlights of the 79th International Motor Show in Geneva include the unveiling of a 1.5 L MCE-5 VCRi engine integrated into a car prototype with two-stage Turbocharger – 420 Nm and 160 kW.
MCE-5 technology already has a 12 year lead on what should be a fundamental stage in the development of IC engines: an “intelligent” variable compression ratio. VCRi heralds the renewal of car engine technology.
The Peugeot 407 type demonstration vehicle presented on the MCE-5 DEVELOPMENT stand (No 3000 in the Green Pavilion) is powered by a 1.5L MCE-5 VCRi engine that develops 220 hp, equal to that of a 3.0L V6 engine, and 420 Nm of torque as of 1500 rpm, comparable to that of a V8 gasoline engine.
A 2010 version of MCE-5 VCRi engine will be equipped with GDI, optimized combustion chambers as well as the advanced management of engine temperature, of the cylinder head, pistons and exhaust manifold.
The power and torque will respectively be ramped up to 270 hp and 460 Nm, while average consumption on the NDEC will drop under the 6.0 L / 100 km mark (less than 140 g of CO2/km). With this type of engine, reaching the target of 120 g of CO2/km seems realistic by 2012-2013 for high-performance vehicles, with a strong reduction in fuel consumption for the whole vehicle range.
This proposal makes even more sense in the current economic, energy and environmental context, by addressing the main factor that will condition the automotive industry for the next 20 to 30 years: gasoline engine efficiency.
