Embodiment Construction

[0013] The following description relates to systems and methods for an engine with partial deactivation. figure 1 The cylinders of a first embodiment of an internal combustion engine applying ignition are schematically shown. figure 2 A schematic diagram of an engine included in a hybrid vehicle is illustrated. image 3 shown for the figure 1 with figure 2 the way the engine runs. Figure 4 An engine operating sequence illustrating various engine operating conditions as engine parameters change is shown.

[0014] Figure 1-Figure 2 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 may be referred to as being in direct contact or directly coupled, respectively. Similarly, elements shown as adjacent or adjacent to each other may, in at least one example, be adjacent or adjacent to each other, respectively. As an example, compo...

Abstract

The invention relates to methods and systems for engine with partial deactivation. Methods and systems are provided for an engine configured to deactivate at least some cylinders. In one example, an engine system may comprise a first group of cylinders having a first compression ratio and a second group of cylinders having a second compression ratio greater than the first.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from German Patent Application No. 102018200298.3 filed on January 10, 2018. The entire content of the above-mentioned application is hereby incorporated by reference in its entirety for all purposes. technical field [0003] The present invention generally relates to an engine having cylinder banks partially deactivated and having different compression ratios in order to increase fuel efficiency at different engine loads. Background technique [0004] Internal combustion engines may be boosted by turbochargers or superchargers to increase engine performance, such as engine power output. Additionally, some internal combustion engines may include deactivatable cylinders to enable a portion of the engine's cylinders to be deactivated when power provided by all or some of the cylinders is not desired, such as during lower engine loads. Deactivation of the cylinders may include one or mor...
