An engine has a housing and a working member movable within an interior of the housing and separating a combustion chamber from a non-combustion chamber. Additionally, the engine may include a chamber-ventilation system that may include a passageway with a first end of the passageway connected to the non-combustion chamber and a second end of the passageway located downstream of the first end of the passageway. The chamber-ventilation system may further include a filter system disposed within the passageway. The filter system may include a filter housing and a filter disposed in the filter housing. Additionally, the chamber-ventilation system may be configured such that, during operation of the engine, gas travels from the non-combustion chamber, into the first end of the passageway, through the passageway, to the second end of the passageway. The engine may further include a first sensor configured to sense an operating condition of the chamber-ventilation system or another operating condition of the engine that relates to an operating condition of the chamber-ventilation system and to produce a signal relating to the operating condition sensed.

What is claimed is: 1. An engine, comprising: a housing; a working member movable within an interior of the housing and separating a combustion chamber from a non-combustion chamber; a chamber-ventilation system that includes a passageway with a first end of the passageway connected to the non-combustion chamber and a second end of the passageway located downstream of the first end of the passageway, wherein the chamber-ventilation system includes a filter system disposed within the passageway, the filter system including a filter housing and a filter disposed in the filter housing, and wherein the chamber-ventilation system is configured such that during operation of the engine gas travels from the non-combustion chamber, into the first end of the passageway, through the passageway, to the second end of the passageway; and a first sensor configured to sense a pressure of gas upstream of the filter system in the passageway and to produce a signal relating to the pressure of the gas upstream of the filter system. 2. The engine of claim 1, further including: a second sensor configured to sense a pressure of gas downstream of the filter system and to produce a signal relating to the pressure of the gas downstream of the filter system. 3. The engine of claim 1, wherein the first sensor is also configured to sense a pressure of gas downstream of the filter system and the sensor is configured to produce a signal relating to the difference between the pressure of the gas upstream of the filter system and the pressure of the gas downstream of the filter system. 4. The engine of claim 1, further including: a monitoring system operatively connected to the first sensor to receive the signal produced by the first sensor and configured to selectively do at least one of storing a code and activating an alarm dependant upon the signal received from the first sensor. 5. The engine of claim 1, wherein the first sensor is configured to sense a condition relating to a magnitude of restriction created in the chamber-ventilation system by the filter and to produce a signal relating to the sensed condition. 6. The engine of claim 1, further including: an air-intake system configured to supply air to the combustion chamber; and wherein the second end of the passageway is connected to the air-intake system. 7. The engine of claim 1, further including: an air-intake system, including a supercharger, configured to supply air to the combustion chamber; and wherein the second end of the passageway is connected to the air-intake system on an inlet side of the supercharger. 8. A method of operating an engine, which engine has a housing, a working member movable within an interior of the housing and separating a combustion chamber from a non-combustion chamber, an air-intake system configured to supply air to the combustion chamber, a chamber-ventilation system that includes a passageway with a first end of the passageway connected to the non-combustion chamber and a second end of the passageway located downstream of the first end of the passageway, and a filter system with a filter housing and a filter, the method comprising: directing gas out of the non-combustion chamber through the passageway; filtering the gas as it passes through the passageway; sensing one or more operating conditions upstream of the filter relating to a magnitude of restriction created in the chamber ventilation system by the filter; and producing one or more signals indicative of the magnitude of restriction created in the chamber ventilation system by the filter based at least in part on the one or more operating conditions sensed. 9. The method of claim 8, wherein sensing one or more operating conditions upstream of the filter includes sensing a pressure of gas upstream of the filter system, and wherein producing one or more signals indicative of the magnitude of restriction created in the chamber ventilation system by the filter based at least in part on the one or more operating conditions sensed includes producing a signal relating to the pressure of the gas upstream of the filter system. 10. The method of claim 9, including: sensing a pressure of gas downstream of the filter system; and wherein said producing one or more signals indicative of the magnitude of restriction created in the chamber ventilation system by the filter based at least in part on the one or more operating conditions sensed further includes producing a signal relating to the pressure of the gas downstream of the filter system. 11. The method of claim 8, wherein sensing one or more operating conditions includes sensing a difference between a pressure of gas upstream of the filter system and a pressure of gas downstream of the filter system, and wherein producing one or more signals indicative of the magnitude of restriction created in the chamber ventilation system by the filter includes producing a signal relating to the difference between the pressure of the gas upstream of the filter system and the pressure of the gas downstream of the filter system. 12. The method of claim 8, further comprising: selectively doing at least one of storing a code and activating an alarm dependent upon the one or more signals produced. 13. The method of claim 8, wherein directing gas out of the non-combustion chamber through the passageway includes directing the gas out of the non-combustion chamber, through the passageway, into the air-intake system. 14. The method of claim 8, wherein said producing one or more signals indicative of the magnitude of restriction created in the chamber ventilation system by the filter includes producing a plurality of signals that are collectively indicative of the magnitude of restriction created in the chamber ventilation system by the filter. 15.
