Summary

00:00 - Alistair's asked, could you re explain the principal of MBT? Yeah absolutely so MBT stands for maximum brake torque timing or minimum timing for best torque.
00:10 And essentially what we're trying to do remember is just choose an ignition timing event so that we end up with peak cylinder pressure occurring at the optimal point in the engine cycle.
00:22 We know by experimentation that this happens to be somewhere around about 16 to 18 degrees after TDC.
00:27 So MBT is simply the ignition timing that produces peak torque.
00:33 If it's producing peak torque we also know that this means we're achieving peak cylinder pressure inside the engine at that optimal point in the engine cycle.
