  • Patent number: 10605147
    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.

  • Patent number: 10584655
    Abstract: An exhaust passage 53 includes: a first passage (high-speed passages 24b, 25b, and 26b); and a second passage (low-speed passages 24c, 25c, and 26c). A turbine housing 560 is connected to the exhaust passage 53 downstream from the collector 54. An exhaust device 100 of an engine 1 includes a valve (an exhaust variable valve 3) to open and close the first passage. A controller (an engine controller 7) closes the valve if an engine speed of the engine 1 is lower than a predetermined engine speed and opens the valve if the engine speed of the engine 1 is higher than or equal to the predetermined engine speed. The controller opens the valve even though the engine speed of the engine 1 is lower than the predetermined engine speed if performing the fuel cut control.
