The Power-Train Control Module (PCM) software which controls the cylinder deactivation function may not operate correctly, and may cause an Intake Valve Rocker Arm
to move out of position and make contact with other internal engine parts.'
The automotive rocker arm
is an important part of the internal combustion engine.
Eaton (eaton.com) is taking advantage of the fundamental architecture of a diesel engine to address exhaust gas emissions by deploying a switchable roller rocker arm
on each cylinder that's electro-mechanically actuated (not hydraulically) so that the exhaust gas recirculation system can kick in right away, even during cold starts, so that the selective catalytic reduction (SCR) system can do its job sooner rather than later.
The purpose of the work is to develop sequence of actions for kinematic research of velocities of points that coincide with the geometric centers of kinematic pairs of the second order fourth class structural group with a movable closed loop formed by three connecting rods and one rocker arm
, based on provisions of the course of the theory of mechanisms and machines on the structural property of mechanisms with structural groups to change the class depending on the conditionally selected other possible initial mechanism, that becomes part of the structure of driven links of the mechanism, provisions on "singular points" and applies the method of theoretical mechanics course on kinematic study of the material points mechanical system with instantaneous velocity center (I.V.C.).
Extreme wear was found on pushrod ends and the rocker arm
This shortened length results in less contact stress on the brake rocker arm
and camshaft (Figure: 4)
The Ace's pumping action was achieved by a horizontal slot in the rocker arm
. A crank pin fit into this slot.
Once Scorpion's engineers felt they had the ultimate design for a shaft mount rocker arm
with endurance qualities, the manufacturing crew produced prototype components for testing.
The fuel/water separator's vent lines that mount into engine's rocker arm
Low-friction technologies such as an offset cylinder and a roller rocker arm
are supplemented by such techniques as intelligent control to lessen friction during power generation and the first adoption of a shell-type needle bearing for the rocker arm
SKF (UK) has launched a new Rocker Arm
Bearing Unit developed to enhance the operating of valve mechanisms in 4-stroke engines.
