Filed:

Dec 26, 2019

Appl. No.:

17/789211

Inventors:

- Cermont-Ferrand, FR

Neal LEIFHEIT - Greenville SC, US

International Classification:

B60C 19/00

Abstract:

A tire having an adhesive sealant applied to the radial interior of the tire in the region of the belt reinforcements of the crown with a noise-dampening foam ring having circumferential grooves in the radial outside surface of the foam is applied to the adhesive sealant. The grooves of the foam are laterally aligned with the circumferential grooves of the tire such that the foam touches the sealant on areas that are not laterally aligned with the longitudinal grooves of the tire.

International Classification:

F02D 41/30

Abstract:

A control system of an engine is provided. The control system includes an inlet sensor configured to generate a signal indicative of an engine inlet air temperature and an intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature. The control system includes a control module communicably coupled to the inlet sensor and the intake manifold sensor. The control module is configured to determine the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine a pre-stored de-rate modifier corresponding to an engine speed. The control module is configured to determine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.
