0 ECENT modifications to the Bristol
AVW six-cYlindered oil engine have improved the maximum power output and fuel economy by 5 per cent. Basically, the combustion characteristics of the early Bristol engine, using the induction swirl with a special venturi choke, have been retained. • In the new design of head, the relation between the piston cavity, injector and valves has been rearranged, bcith valves now coming within the cylinderbore area, No local recesses are now needed in the cylinder liners.
Not only has the new head design improved output and fuel consumption, but it is considered that valve and valveseat life will be increased. While the head was being redesigned, the opportunity was taken to improve the water flow both in direction and volume. At the same time art improved water pump of larger capacity was introduced.
