Throttle valve for internal combustion engines

The present disclosure generally relates to a self-cleaning throttle valve (80) to be used in an internal combustion engine. The disclosed throttle valve (80) may comprise a valve body (100) configured to be rotatably arranged within a housing (90). The valve body (100) may comprise a circumferential wall (102) and an opening (108) therethrough. The opening (108) may be rotated into at least partially alignment or fully out of alignment with an outlet (96) of the housing (90), thereby enabling or restricting exhaust gases to pass through the outlet (96). At least one scraping element (140) may be externally attached to the circumferential wall (102) and may be configured to scrape over an inner surface of the housing (90) when the valve body (100) is rotated.
