A solenoid valve is an electromechanical valve controlled by an electric current. A solenoid creates a controlled magnetic field when an electrical current is passed through it. This magnetic field affects the state of the solenoid valve, causing the valve to open or close. Diesel fuel shut-off solenoids transport diesel fuel from a machine’s gas tank to its engine.
A glow plug is a heating device used to start diesel engines. The glow plug is a pencil-shaped piece of metal with a heating element at the tip. This heating element, when electrified, heats due to its electrical resistance and begins to emit light in the visible spectrum, hence the term “glow”-plug. The fuel injector spray pattern then impinges directly upon the hot tip of the glow plug during the injection of fuel at top dead centre. This enables the fuel to ignite even when the engine is insufficiently hot for normal operation.
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
