摘要:
An electric power generation system (20) is disclosed, which includes a back-up electronic power generator (22) driven by a four-cycle internal combustion engine (30). The engine (30) includes a plurality of reciprocating cylinder (C1-C6) each rotatable coupled to a crankshaft (34), which drives the electric power generator(22). The engine (30) also includes a compressor (72) along an intake pathway (50) to deliver pressurized air to the cylinders (C1-C6) and a turbine (78) along an exhaust pathway (60) to power the compressor (72) when driven by exhaust discharged from the cylinders (C1-C6). The engine (30) is prepared to accept a generator load by increasing boost pressure provided by the compressor (72). This increase is accomplished by skip-firing the cylinders (C1-C6) in a selected pattern, retarding ignition timing for the cylinders (C1-C6), or a combination of these techniques. A unique skip-fuelling control pattern is also disclosed.
摘要:
An engine oil capacitor which allows a larger volume of oil to be used in an internal combustion engine without reducing fuel economy or increasing engine package size. Oil flow through the normal oil drainback holes (34) is partially restricted, resulting in a substantial quantity of oil being temporarily stored in the camshaft compartment (32), during engine operation.
