Efficient light vehicle pcu to meet rota 2030 targets

Abstract

The contribution of the Power Cell Unit (PCU) to the overall engine efficiency through friction reduction has been widely discussed along the past years. The recent launch of the new governmental legislation named ROTA 2030 as replacement for INOVAR-AUTO has established new challenging targets of fuel consumption reduction, making the need for new modern technologies even more prominent. The adoption of downsized engines sometimes combined with turbocharger technology has shown to be the choice of car manufacturers to comply with the new rules. As a result, PCU components will have to contribute to fuel consumption reduction, besides being more demanded in terms of performance and robustness. Car manufactures that do not comply with the new targets by 2022 will be in cost disadvantage in a very competitive market. Using the experience gained on INOVAR-AUTO, a high feature PCU was selected to attend this new market demand. Results of numerical simulation and fuel consumption in a dynamometer bench tests are presented to support the discussions.

Influência do perfil do anel de controle de óleo no consumo de óleo em tempo real e emissões de particulado

“…There is already available technology to decrease the vehicles emissions, for example optimized combustion engine power cell unit (PCU) [3] and post-treatment systems. Moreover, the automotive industry challenge is to enhance even more the components durability generating lower emissions.…”

“…OEM´s are putting more efforts towards engine efficiency increase in the past few years. The reason for that is known: besides reduced fuel consumption driven by customers, tax reduction given to more efficient engines can also improve competitiveness [1]. Such incentives are linked to programs like ROTA 2030.…”
