Embodiment Construction

[0045] The following description relates to systems and methods for a variable displacement engine (VDE). Figure 1 to Figure 3 Various views of the VDE are shown. Figure 4 A method for operating a VDE comprising one or more balance shafts is shown. Figure 5 A method is shown for operating one or more balance shafts in response to engine speed. Figure 6 A method is shown for operating one or more balance shafts in response to one or more cylinders being deactivated. Figure 7 Graphs illustrating the operating range during cylinder deactivation for previous examples of engine-only actuated balance shafts and examples of the present disclosure for one or more balance shafts that may be selectively operated via an electric motor or engine are shown picture.

[0046] Figure 1-3 Example configurations are shown with relative positioning of various components. In at least one example, if shown as being in direct contact, or directly coupled, with each other, such elements m...

Abstract

The disclosure relates to an engine assembly, and an internal combustion engine assembly for a motor vehicle is provided. The engine assembly comprising: an engine; an electric motor; and a balance shaft comprising an eccentric mass, wherein the electric motor is configured to selectively rotate the balance shaft in order to balance a vibration characteristic of the engine. A method of operating the engine assembly is also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to UK Patent Application No. 1619819.4 filed 23 November 2016. The entire content of the above-mentioned application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present disclosure relates to an engine assembly for a motor vehicle, and particularly, but not exclusively, to an engine assembly configured to improve fuel consumption of a motor vehicle. Background technique [0004] Internal combustion engines for vehicles, such as motor vehicles, may be used in many different configurations, which may include different numbers of cylinders and different arrangements of cylinders with different firing timings and / or firing orders. Some engine configurations may result in an inherent imbalance in the forces exerted on the crankshaft of the engine during engine operation. This can result in reciprocating, rocking, or torsional vibrations...
