The most important challenge facing automotive manufacturers for the year 2005 is the achievement of the ultra-low emission levels and up to 40% lower CO2 emission from the vehicle fleet. This paper outlines the design and development of the 1.2-liter TDI 4-cylinder engine concept. The design approach to 4 valve per cylinder in 70 mm bore is shown and discussed. The combustion system development of a production-compatible 300 cc single-cylinder engine using Lucas-Varity Common Rail (LVCR) is presented. Results demonstrate specific rating of 50 kW/liter and potential for 3 liter/100 km fuel consumption and EURO IV emissions with minimal aftertreatment.
