US 2017/0101917 A1 · ENGINE WITH EXPLOSION PROTECTION

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.

Dependent claims

An explosion protection system, for an engine having an exhaust output at which high temperature gases are discharged, comprising

a turbocharger and an exhaust manifold coupled to each other and to the exhaust output of the engine;
a first coat of thermal insulation material applied to the outer surfaces of said turbocharger and said exhaust manifold;
and
a second coat of surface protecting material applied over the first coat to protect the first coat from being scratched or damaged;
wherein said first and second coats function to decrease the temperature along the outside coated surfaces of said turbocharger and said exhaust manifold below a predetermined level.
