cone angle plane angle injection angle help

[toseland]

that would be ideal... but bear in mind as Darren says the dynamics of the spray become very important when yuou start to get bigger numbers..

specifically the HDi injectors are designed to desposit the fuel in the recess in the piston.. if you start to get detonation or the beginings of detonation outside of this then you will start to crack pistons because of the unequal forces..

the plane angle is vitally important in tuning to higher levels, moreso i would say than the cone angle
