ABSTRACT:
A system for limiting the air intake to a diesel engine or the like under restricted operating conditions. A closure valve is mounted in the air intake passage of a diesel engine. The system includes a fluid pressure responsive mechanism for closing the valve under restricted operating conditions, and an orifice positioned downstream of the valve and sized to the particular engine associated therewith. The orifice is sized to permit air flow into the air intake passage of the engine at a rate which is about 60% of the normal, full-flow rate for normal engine operation at specified RPMs. The pressure responsive mechanism is coupled to a closed atmosphere pressurizing system so as to be actuated in closing the air intake valve when the pressurizing system is activated and to automatically permit the air intake valve to be opened when the pressurizing system is deactivated or when its pressurized fluid is exhausted.
