Abstract: An air cleaner assembly can contain an air filter element to filter contaminant material out of an air stream. In some examples, the air cleaner assembly includes a housing with an integrated noise suppression chamber for supplying air to a downstream compressor. The housing forms a cavity into which an air filter element is inserted. Contaminated air enters the housing and passes through the air filter. Filtered air can discharge from the housing through a first opening supplying air to a combustion engine and a second opening supplying air to a compressor. Air supplied to the compressor passes from the interior of the housing containing the filter element and through the integrated noise suppression chamber before being discharged. The acoustic energy released by the filtered air stream exiting the air cleaner assembly may be reduced by passing through the noise suppression chamber.

Abstract: Systems and methods for regulating oil flow to an engine are described herein. An oil pressure target for the engine is determined based on one or more engine operating parameters. Oil flow to the engine is controlled based on the oil pressure target. Closed-loop feedback of oil pressure of the engine is obtained from at least one sensor during the controlling of the oil flow to the engine. A pressure difference between the oil pressure target and the closed-loop feedback of the oil pressure of the engine is determined. The oil flow to the engine is adjusted based on the pressure difference.
