摘要

Robert Bosch GmbH is developing a common-rail fuel-injection system for diesels that would achieve efficiency-enhancing pressures of around 36,200 psi (2,500 bar) or even 43,500 psi (3,000 bar), far higher than current-production, best-in-class 26,100-psi (1,800-bar) systems, or next-generation 29,000-psi (2,000-bar) systems. Stefan Kampmann, senior vice president of engineering for Bosch diesel systems, says the program for HADI, or Hydraulically Assisted Diesel Injection, still is in advanced development. Higher pressure results in more control of the combustion process. Engineers can use the higher pressure to reduce emissions or improve fuel economy.
