Abstract
An engine system with advance detection of detonation and/or pre ignition, the system comprising an engine, operative for propulsion of a vehicle by generating rotational motion, whose rotational velocity over time is monitored; and a detonation and/or pre ignition detector operative to provide an alert for impending detonation and/or pre ignition of the engine, if the rotational velocity fluctuates over time to an extent which is predetermined to be unsafe.
Claims26
An engine system with advance detection of detonation and/or pre ignition, the system comprising:
- a turbocharged engine comprising a turbo waste gate, the turbocharged engine being operative for propulsion of a vehicle by generating rotational motion, whose rotational velocity over time is monitored;
- and
- a detonation and/or pre ignition detector operative to provide an alert for impending detonation and/or pre ignition of the engine, if the rotational velocity fluctuates over time with a frequency which is predetermined to be unsafe, and
- a control coupled to said detonation and/or pre ignition detector and configured for selectively operating said turbo waste gate responsive to said alert being provided.
A system for advance detection of detonation and/or pre ignition in an engine, the system comprising:
- a detonation and/or pre ignition detector operative to provide an alert for impending detonation and/or pre ignition of an engine generating rotational motion whose rotational velocity over time is monitored, if the rotational velocity fluctuates over time with a frequency which is predetermined to be unsafe;
- and
- a control coupled to said detonation and/or pre ignition detector and configured for operating a turbo waste gate responsive to said alert being provided.
A method for advance detection of detonation and/or pre ignition in an engine, the method comprising:
- providing an alert for impending detonation and/or pre ignition of an engine generating rotational motion whose rotational velocity over time is monitored, if the rotational velocity fluctuates over time with a frequency which is predetermined to be unsafe;
- and
- operating a turbo waste gate responsive to said alert being provided.
A method for operating aircraft with advance detection of detonation and/or pre ignition, the method comprising:
- providing a turbocharged engine airlifting a structure capable of being airborne by generating rotational motion whose rotational velocity over time is monitored, the engine comprises a turbo waste gate;
- and
- providing an alert for impending detonation and/or pre ignition of the engine, if the rotational velocity fluctuates over time with a frequency which is predetermined to be unsafe
- operating the turbo waste gate responsive to said alert being provided.
A computer program product, comprising a computer usable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for advance detection of detonation and/or pre ignition in an engine, the method comprising:
- providing an alert for impending detonation and/or pre ignition of an engine generating rotational motion whose rotational velocity over time is monitored, if the rotational velocity fluctuates over time with a frequency which is predetermined to be unsafe;
- and
- operating a turbo waste gate responsive to said alert being provided.
