Study on effects of ammonia-diesel blends in CI engines

Green Car Congress

An international team from the Middle East has investigated the characteristics of diesel engines powered by petroleum diesel fuel blended with different volumetric percentages of aqueous ammonia. In the simulations, the team used a constant engine speed of 1500 RPM, an injection pressure of 160 bar, and 20° BTDC injection timing.

Alumobility study: aluminum top hat provides automakers a lighter, sustainable alternative

Green Car Congress

Further, the aluminum top hat can meet or exceed performance criteria while using the same package space as steel, offering an opportunity for weight savings that translates into improved fuel economy and lower emissions on an internal combustion engine vehicle, or greater performance and range or reduced battery size for electric vehicles.

U-M researchers challenge USPS EV environmental study

Green Car Congress

A new University of Michigan study finds that making the switch to all-electric mail-delivery vehicles would lead to far greater reductions in greenhouse gas emissions than previously estimated by the US Postal Service (USPS). The Postal Service has not commented on the U-M study. Earlier post.). The USPS estimate was 10.3
