The article examines the design and development of electronic vehicle ignition systems and their role in improving fuel consumption and reducing air pollution through greater efficiency. Although existing contact breaker-based systems are comparatively cheap to replace, they are inefficient due to mechanical limitations. Present electronic ignition systems such as the piranha, which are likely to be incorporated in high-volume production vehicles, will probably retain the existing distributor unit but replace the contact breaker assembly with magnetic sensors or opto-electronic devices. Another development is the introduction by Petrol Injection Ltd. Of an electro-pneumatic emission control fuel injection system. This equipment features electronic switching to control air/fuel ratio resulting in fuel savings of 10-20% when compared with carburettor systems. /TRRL/
