Abstract: The exhaust system of a diesel engine includes components such as a turbocharger and an exhaust manifold which can have very high internal temperatures (e.g., any surface having a temperature above 135° C.). In accordance with the invention the components subject to the high temperatures are coated with at least a first layer of thermally insulating material and a second layer overlying the first layer to provide surface protection. So coated, the temperature of the outer coated surfaces of these components is brought below an undesirably high level. Also, selected ones of the components may be water cooled and/or have a fitted jacket and/or be placed within an explosion proof enclosure. The input fuel line may also include a magnetic explosion proof fuel economizer to control the combustion process and reduce the internal temperature.

Abstract: Explosion proof enclosures and explosion proof connectors and sensors are used to render a machine, intended to be operated in an explosive environment, explosion proof. An explosion proof connector includes an intermediate section having an input portion to receive a cable from a terminal external to an explosion proof enclosure and an output portion for passing the cable for connection to a terminal within an explosion proof enclosure. A sealing tube which extends between the input and output portions has a central opening for enabling a cable to be passed through. A sealant may be injected into the sealing tube to form an air tight connection between the cable and the inner walls of the sealing tube which inhibits a hazardous condition from passing through and around the sealing tube. An explosion proof sensor includes potting and encasing the sensor in its own explosion proof case.
