Fuel Injection and EGR Adjustments on The Renault R17 TS 720518

Because of low nitrogen oxide emissions, a version of the Renault R17 TS equipped with a high-performance engine was selected for the American market. This paper discusses problems encountered in adapting a Bosch electronic fuel injection system to a 1600 cm3 engine to meet American standards up to 1974. The principal problems solved were those posed by intermediary operating speeds. This study also gives an idea of the pollution limits which can be obtained with an injection system which incorporates various important adjustment factors.
Engine specifications are presented, as are decriptions of the electric regulation, electric and pneumatic cold-start, and fuel feeding circuits. The various modifications to the engine are also described.
