For the purpose of this chapter, the following definition shall apply unless the context clearly indicates or requires a different meaning.
ENGINE COMPRESSION BRAKING. Any deliberate method of reducing vehicle speed in a manner that produces a loud noise or increased emissions, particularly including: the venting of the cylinder of an engine midway through its cycle resulting in the discharge of compressed air into the atmosphere; also, the deliberate obstruction of the exhaust manifold thereby compressing inducted air against the exhaust brake butterfly. ENGINE COMPRESSION BRAKING mechanisms are also known as compression brakes, exhaust brakes and engine retarders.
