When Renault and American. Motors Corporation joined forces to introduce the 1983 Alliance, they decided to add one uniquely American feature, a highly responsive, low cost electronic fuel injection system. Bendix was selected to develop the fuel controls for the 1.4-liter engine utilizing an innovative single point system concept. The high precision fuel injection system makes the Alliance one of the most fuel efficient cars manufactured in America. With the Bendix system, the small engine produces solid performance and meets EPA emission standards with a relatively small catalytic converter.
The Bendix system consists of a multiprocessor electronic control unit, a throttle body assembly including a single point injector, pressure regulator and an idle speed actuator, a low pressure fuel pump, a manifold pressure sensor, and two temperature sensors. Adaptive control, automatic idle speed regulation, and on-board diagnostics are some of the features that distinguish the system as an advanced engine control system. Modern digital electronic technology makes possible a base system that is easily adapted to a variety of vehicles.
