The specific power output of the gasoline and diesel engine variants within engine families covers an increasingly broad spectrum. Alongside engines with an average power output and a moderate mean effective pressure, more and more high-powered variants are coming onto the market. An analysis carried out by AVL highlights the specific modifications to the engine components and the development process that are needed in order to put in place a modular strategy.
Efficiency and Performance Concepts for Gasoline and Diesel Engines
Increasing differentiation can be observed in gasoline and diesel engines between concepts oriented towards fuel economy and extremely performance-oriented concepts. Consistent throughout is the use of turbocharging and direct injection [1, 2, 3]. The efficiency concepts focus on valvetrain variability, internal and external exhaust gas recirculation, and increasingly extended expansion by Miller- or Atkinson cycle. The combination of part load efficiency...
