Bosch Developing Ultra-High-Pressure Diesel Injection

STUTTGART – 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.
