Abstract:
A method for monitoring torque in an engine for use in a motor vehicle, said engine having a lambda probe giving a lambda for the operation of the engine, said method comprising the steps of:operating the engine in a stratified condition, wherein lambda is greater than 1.4, said operating said engine in said stratified condition comprises the steps of:identifying a speed (n) of the engine;identifying a fuel mass (K) supplied to the engine;deriving a reference torque value (M.sub.g) from said speed (n) and said fuel mass (K);comparing said reference torque value (M.sub.g) with a torque value (M.sub.max) specified by a driver of the vehicle;performing torque-reducing intervention means if said reference torque value (M.sub.g) exceeds said torque value (M.sub.max) by a specifiable amount.
