摘要： A turbocharged internal combustion engine system includes at least one high pressure turbocharger and at least one low pressure turbocharger arranged in series. A fuel source that provides fuel for gaseous fuel induction operation of the engine is connected to inject fuel between the low pressure compressor of the low pressure turbocharger and the high pressure compressor of the high pressure turbocharger.

摘要： An engine includes a cylinder having an internal combustion chamber and extending longitudinally, a cylinder head coupled to the cylinder, and a fuel-fed pre-chamber positioned within a portion of the cylinder head. The pre-chamber includes a pre-chamber volume and plurality of nozzle holes extending from the pre-chamber volume. The engine also includes an ignition source positioned longitudinally above the pre-chamber volume and a locating member positioned on at least one of the pre-chamber and the cylinder head. The locating member is configured to position the pre-chamber in a predetermined orientation within the cylinder head.
