MOTORES DE BAIXA CILINDRADA: desempenho e potência na atualidade

Abstract

This study investigates the evolution of the automotive industry, focusing on improving engines for better efficiency, fuel economy, and environmental compliance. The aim is to compare a downsized 1.0-liter engine with advanced technologies to an older 2.0-liter engine, identifying differences, design improvements, and assessing their durability, without considering a specific schedule. The research focuses on reducing engine size to lower emissions while maintaining performance and durability. The hypothesis supports that the new downsized engines will have performance and durability equivalent to larger engines. To achieve these goals, the research selects engines for comparison, analyzes employed technologies, evaluates environmental standards, compares old and new technologies, collects engine data, and presents the results. The study is justified by the need to reduce CO2 emissions and modernize automotive technology. Focusing on the EA 211 engines with direct injection, turbochargers, and innovations, along with the older EA 113, the work underscores the necessity of technological updates. The theoretical framework covers the history of internal combustion engines, basic concepts, details of EA 113 and EA 211 engines, and a performance comparison between them, highlighting fuel injection technologies, turbochargers, and variable valve timing systems.The methodology involves bibliographic research, field data collection, exploratory research, and comparative engine analysis to enhance understanding of the proposed topic.
