RENAULT CLIO This month I intent to focus on the Renault Clio utilising the Bosch monopoint injection system incorporating the siemans controller. There are several variants across the production range so expect some small differences. The variant chosen is compatible with the 1.2-1.4 series Clio E7F/ E7J engine codes. The throttle body injection is a low-pressure system, delivering fuel at atmospheric pressure into the manifold, not dissimilar to the carburettor The fuel pressure is maintained at a constant 1 Bar. The injector is triggered with every ignition dwell control pulse. It’s opening is the only variable factor in maintaining the correct air fuel ratio. Sykes Pickavant offer an excellent pressure kit with comprehensive adapters. The key sensor input to the siemens ECM are: - speed and position via an inductive crank sensor producing a modified sine wave located at the rear of the block. The output should exceed 5 volts peak to peak cranking, and will increase proportional to engine speed. This signal is modified to a digital signal by the ECM and sent to the composite ignition module assembly see waveform (1)
