Harry Weslake was a proflic engine designer. He has quite a
number of patents for head design and combustion chamber details in
particular. Re BMC he was responsible for the 'heart' shape of the
cylinder combustion chamber which gave good swirl to the incoming
fuel/air mixture promoting the burn characteristics he considered
optimum.
This combustion chamber was applied to a number of BMC cylinder
heads.
Harry was also given credit for the A-Series cross flow semi
downdraught head used on the late ( 1967 & 68 ) Sebring and LeMans
Sprites that used Lucas mechanical fuel injection. Good for 150mph at
LeMans with a 1293cc engine
Dan Gurney used him to design his formula one 12 cylinder
Guerny-Weslake engine
Harry also was called upon to design a single cylinder speedway bike
engine.
