A method 110 of deriving reciprocating device 12 component health includes receiving 114 a signal from a knock sensor coupled to a reciprocating device 12, deriving 118 total harmonic distortion (THD) at one or more frequencies, and determining 120 whether...

A method of monitoring an operating event of a combustion engine includes receiving a noise signal sensed by a knock sensor disposed in or proximate to the combustion engine, correlating the noise signal with a fingerprint (130) having at least an ADSR env...

The device has a protection plate (1) connected to pin guides (2) by reinforcements (3). The plate is screwed on a cylinder head by a screw (5). A reinforcing stand (4) is screwed on a cylinder case (8) and on the plate, using a screw (6). The guides are p...

Device for monitoring the cylinder pressure in a cylinder (1) of a diesel engine comprises a measuring unit (12) formed as a distance sensor and/or a spacer sensor. Independent claims are also included for the following: (1) Process for monitoring the cyli...

A combustion pressure sensor (1) for an internal combustion engine is provided. The sensor includes a sensing element such as a piezoelectric device (122) sensitive to a physical load applied thereto to produce an electric signal indicative thereof and a b...

The piston ring has a slide surface (10) formed on a ring edge zone (11,12). The edge zone has a worked modification (5) acting with a sensor to generate ring wear information. The modification is located in an edge section of the edge zone on the upper an...

The reference element (100) is provided by a ring fitted coaxially to the crankshaft and divided into different sections (101,102) around its periphery. The ring can cooperate with a sensor for providing detectable impulses during the crankshaft rotation. ...

First brake components (9a, 9b) rotate with the engine components. Associated braking components (12a, 12'a) are controlled to move between braking and released positions, to brake rotary parts of the engine. An Independent claim is included for the corres...
