Abstract

A torque spike cancellation device for an internal combustion engine is provided. The torque spike cancellation device comprises a first member, a second member, and a third member. The first member is in driving engagement with an output of the internal combustion engine. The second member is in driving engagement with the first member. The third member is in driving engagement with the second member. An angular deviation between the first member and one of the second member and the third member causes a cyclical acceleration of the third member. The cyclical acceleration of the third member adjusts a torque applied to the third member by the internal combustion engine.

Description

[0001] related application [0002] This application claims the benefit of US Provisional Application No. 61 / 787,319 filed March 15, 2013, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to internal combustion engines, and more particularly to torque peak canceling devices for internal combustion engines. Background technique [0004] Due to recent improvements in combustion engine technology, there has been a tendency to downsize internal combustion engines used in vehicles. Such improvements also result in more efficient vehicles while maintaining similar performance and vehicle form factors favored by consumers. [0005] A common improvement for internal combustion engines is the addition of a supercharger or turbocharger. Typically, the addition of a supercharger or turbocharger is used to increase the performance of an engine that has been reduced in displacement or number of engine cylinders. Such imp...
