Abstract: A lubrication bypass system is disclosed for controlling flow of a lubricant to a reciprocating machine, such as two-stroke engines and two-stroke compressors, based upon one or more operating parameters. The lubrication bypass system can be positioned in fluid communication with a lubrication system that transports a primary flow of the lubricant from a lubricant reservoir to the reciprocating machine cylinder at a predetermined primary flow rate. The lubrication bypass system can be configured to divert a portion of the primary flow, a bypass flow, from the lubrication system at a bypass flow rate based upon the operating parameters. As a result, a secondary flow of lubricant remaining within the lubrication system can be supplied to the reciprocating machine at a secondary flow rate that is less than the primary flow rate. In this manner, the lubrication bypass system can regulate the secondary flow rate.

Abstract: A low emissions 2-stroke natural gas fueled engine includes at least one cylinder with an exhaust port in communication with a silencer/catalytic converter unit. The unit has first and second volumes in communication with each other. The first volume dampens spurious exhaust pressure excursions and removes particulates in the exhaust. The second volume houses an oxidation catalyst for treating exhaust to reduce exhaust emissions. The engine oil has at most 10 ppm zinc content to reduce metal poisons contained in the exhaust prior to contact with the oxidation catalyst. The engine oil preferably has a very low ash content to minimize sulfur combustion components in the exhaust to reduce masking of the oxidation catalyst. The first volume preferably has a pressure relief valve set to relieve at a pressure greater than the maximum normal operating pressure of the engine to avoid excessive pressure excursions of the engine exhaust from damaging the oxidation catalyst.

Abstract: A hydrocarbon adsorber and a thermoplastic resin combined and formed to a porous scavenger for insertion into the air intake system of a motor vehicle engine. The resulting porous scavenger adsorbs volatile hydrocarbon molecules from raw fuel remaining in the air intake when the engine is shut off. The adsorbed molecules are then stripped or purged from the scavenger and reintroduced into the air intake when the engine is next started.

Abstract: A system and method for processing thermal signature data is provided. The system provides a thermal signature data processor that analyzes one or more pixels to determine whether an aspect of an alarm-worthy event has occurred. In one embodiment, the system analyzes visual data with relation to the thermal signature data to determine whether an alarm-worthy event (e.g., intrusion) has occurred and subsequently generates an alarm to indicate an intrusion or alarm-worthy event.
