Abstract: An apparatus is provided to test valves. The apparatus includes a sensor and a driving mechanism. The driving mechanism is configured to control an external camshaft that is coupled to a valve train of an engine head. The apparatus controls the driving mechanism to control a rotation of the external camshaft that further controls an activation of each valve of the valve train associated with the engine head. The apparatus further controls the sensor to acquire information associated with the activation of each valve of the valve train based on the rotation of the external camshaft. The apparatus further compares the acquired information with pre-stored information, to determine an abnormality in each valve of the valve train, and generates a notification based on the comparison.

Abstract: An apparatus is provided to test valves. The apparatus includes a base and an actuation mechanism with an actuator having a first end coupled to the base and a second end retractably extends from the base. The apparatus further includes a common platform with a first surface and a second surface. The first surface coupled to the second end of the actuator and moves from the base, based on an extension of the actuator. The apparatus further includes a plurality of engagement members each of which includes a first portion coupled to the first surface and a second portion coupled to the second surface. The apparatus further includes a plurality of sensors coupled to the plurality of engagement members such that each sensor of the plurality of sensors is coupled to corresponding member of the plurality of engagement members and coupled with a valve associated with a machine.

Abstract: An apparatus is provided to test valves. The apparatus includes a support structure and a plurality of engagement members coupled to the support structure. Each member of the plurality of engagement members is coupled with a valve of a valve train associated with an engine head. The apparatus further includes a camshaft, which includes a plurality of lobes coupled to the support structure. Each lobe of the plurality of lobes are equally spaced from each other and coupled to a member of the plurality of engagement members. The apparatus further includes a driving mechanism coupled to the camshaft, which is configured to rotate the camshaft and control each member of the plurality of engagement members to further control an activation of each valve of the valve train associated with the engine head.

Abstract: An apparatus is provided to test valves. The apparatus includes an actuation mechanism having an actuator that seals a valve of a combustion chamber of an engine. The apparatus further includes a flow control device that controls a flow of a pressurized fluid to the combustion chamber. The apparatus further includes a plurality of sensors having a first sensor and a second sensor. The first sensor is disposed in an inlet port of the combustion chamber to detect a first flow rate of the pressurized fluid in the inlet port. The second sensor is disposed in an exhaust port of the combustion chamber to detect a second flow rate of the pressurized fluid in the exhaust port. The apparatus further includes a notification device configured to generate an alert based on the detected first flow rate and the detected second flow rate.
