Abstract:
1. An engine pre-heater system comprising: (a) a gas burner unit which includes (b) a first support element fixed to the fluid conduit, the first support element including a plurality of fluid passages defined therethrough, the fluid passages defined in said first element being in fluid communication with the outlet end of the fluid conduit; (c) a second support element fixed to the fluid conduit, the first support element including a plurality of fluid passages defined therethrough, the fluid passages defined in said second support element being in fluid communication with the outlet end of the fluid conduit via the fluid passages defined in said first support element whereby heated gas exiting the outlet end of the fluid conduit flows through the fluid passages defined in said first support element to and through the fluid passages defined in said second support element; (d) a first hollow cylindrical housing fixed to the first and second support elements, the first hollow cylindrical housing surrounding the fluid conduit near the outlet end of the fluid conduit, the first hollow cylindrical housing including (e) a second hollow cylindrical housing fixed to the first and second support elements, the second hollow cylindrical housing surrounding said first hollow cylindrical housing, the second hollow cylindrical housing including (f) first and second flexible fluid conduits extending through the ports defined through the cylindrical walls of said first and second cylindrical housings, said first flexible fluid conduit having an inlet end fluidically connected to a fluid circuit of an internal combustion engine and an outlet fluidically connected to the inside volume of said first hollow cylindrical housing, said second flexible fluid conduit having an inlet end fluidically connected to the inside volume of said first hollow cylindrical housing and an outlet end fluidically connected to the fluid circuit of the internal combustion engine; (g) a quick-connect/disconnect fitting on the inlet end of said first flexible fluid conduit; and (h) a quick-connect/disconnect fitting on the outlet end of said second flexible fluid conduit.
