ok, did i say poppet valves. i said valves. just like those used in a 4 stroke engine. research the detroit engine. from and inline 2 to a v24 they used mushroom valves just as those in all cars & trucks and alike. using a cam, rockers, springs and push rods. only on the exhaust side, every...
more 4 stokes, is because of epa reg's that all, but put a valve train on the exhaust side and a forced induction system. this will clean the old burnt fuel, for the new air charge. and there you go. with the time to have direct injection.
if its a time issue, wouldn't the addition of more injectors put the proper fuel mix into the cylinder. or is this because it wouldn't have time to spread the fuel about the area fast enough to mix properly. even using fast spraying high flow injectors. but it that's still the problem. so how...
i never saw a bore size. so this may be a problem. with size limiting factors for extra injectors. so how many can be mounted in a given space without detrimental head strength loss.
ok, then multiple high flow injectors in the head, should cover the fuel needs and a balanced air fuel mix across the piston, with a centrally located spark gap plug. may cover the needs.
i've been reading on this string. why are you worried about the waist of gasses out the exhaust. if the gasses doesn't suspend fuel. direct injection! much like a 2 stroke detroit diesel. supercharged and with direct injection, there is no waist of fuel on the return trip of the piston. the...
