摘要： A removable blade assembly with an attachment arm slidably mounted over the support boom of a trencher machine. The attachment arm is stabilized in place on the support boom with pressure point bolts. From the attachment arm extend an angle support and an extending support block to stabilize a stabilization post leading to the blade-pivot assembly. The blade-pivot assembly includes a blade assembly pivotally mounted on a triangular-shaped housing frame. The blade can be swiveled in each direction from the trencher machine to backfill debris as desired.

摘要： A reciprocating internal combustion engine has a pilot mask situated about the intake valve seat and extending into the engine cylinder and a variable camshaft timing drive system which positions the camshaft such that the lift of the intake valve and the height of the pilot mask are approximately equal when the piston is moving at the point of its greatest velocity during the intake stroke.
