Balancing the requirements for low emissions, low fuel consumption and reliable traction power-MAN Ruston's solution

Abstract

Ruston diesel engines have been operating in locomotives since 1933. Increasing concerns about global warming and depletion of fossil fuels have led to regulations from many agencies to place controls on end users of diesel fuelled prime movers. The paper seeks to define and explain the regulations, present a summary of combustion chemistry and then to explain one manufacturer's thorough approach to the most efficient reduction of fuel born pollution as it relates to engines for traction applications. Reduction in fuel used and pollutants emitted are presented and the improved economies discussed.
