Some 80's Mitsubishi 4 cylinders ( also found in Chrysler products ) used the same process called MCA Jet. It is far easier to light off a rich mixture than a lean one. On the Mitsu it really isn't a pre chamber, it is a nozzle that directs a small amount of a rich mixture towards the spark plug that is in the standard location.
