Embodiment Construction

[0032] The following description relates to systems and methods for adjusting the vibration frequency of a resonant system to vary the volume of an engine intake manifold based on engine speed. An exemplary embodiment of an engine system including an intake system and an exhaust system is in Figure 1-4 shown in . In each example embodiment, the intake system further includes one or more resonance systems to vary the volume of the intake system. The engine controller can be configured to execute control routines ( Figure 5 Exemplary routine for ) to vary the volume of the intake system based on engine speed by adjusting the resonance system.

[0033] refer to figure 1 , an engine system 2 for a vehicle such as a motor vehicle includes an engine 4 , an intake system 6 , an exhaust system 8 and a turbocharger 12 .

[0034] The intake air enters the intake duct 10 of the intake system 6 via an intake port 14 before being compressed by the turbocharger compressor 12a. The tu...

Abstract

Methods and systems are provided for varying the volume of an engine intake system to increase the volumetric efficiency of the engine. In one example, a resonance system may be coupled to the engine intake system and a position of a movable element in the resonance system may be varied to vary the volume of the chamber in accordance with engine speed. The intake system provides improved volumetric efficiency for the engine.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to UK Patent Application No. 1602324.4, filed 9 February 2016, and UK Patent Application No. 1602345.9, filed 10 February 2016. The entire contents of each of the above applications are incorporated herein by reference for all purposes. technical field [0003] The present invention generally relates to systems and methods for an engine having an air intake system configured to increase the volumetric efficiency of the engine. Background technique [0004] Air intake systems for motor vehicle engines are typically designed with a fixed geometry tuned to most efficiently provide air to the engine's cylinders at a particular desired engine operating speed. The desired engine operating speed may be the speed at which the engine produces peak power or peak torque. Alternatively, the desired engine operating speed may be the speed at which the engine operates most efficiently when the vehi...
