Abstract

A flame trap housing 36 for a flame trap 34 of a compression ignition engine has an inlet 38 configured to engage an air outlet of a turbocharger and an outlet 40 configured to engage an inlet of an inlet after-cooler. The housing 36 is double skinned, having an inner skin 46 defining a flame trap compartment 35 and an outer skin 48 arranged in a spaced relationship relative to the inner skin 46 , to define a fluid flow path 52 for the flow of a cooling fluid about the inner skin 46 of the housing 36.

Claims (10)

1. A flame trap housing for a flame trap of a compression ignition engine, the housing having an inlet configured to engage an air outlet of a turbocharger and an outlet configured to engage an inlet of an inlet after-cooler, the housing being double skinned, having an inner skin defining a flame trap compartment and an outer skin arranged in a spaced relationship relative to the inner skin, to define a fluid path for the flow of a cooling fluid about the inner skin of the housing.

2. The housing according to claim 1 , which defines a cooling fluid inlet and a cooling fluid outlet of the fluid path.

3. The housing according to claim 1 , in which the cooling fluid outlet is situated at a furthermost position on the housing relative to the cooling fluid inlet.

4. A fluid input assembly for a compression ignition engine, the assembly including:

a turbocharger;

a flame trap including a housing comprising an inlet connected to an air outlet of a turbocharger and an outlet configured to engage an inlet of an inlet after-cooler, the housing being double skinned and having an inner skin defining a flame trap compartment and an outer skin arranged in a spaced relationship relative to the inner skin, to define a fluid path for the flow of a cooling fluid about the inner skin of the housing; and

an inlet after-cooler connected to an outlet of the flame trap housing.

5. The assembly as claimed in claim 4 in which the turbocharger includes a component comprising a turbocharger housing defining a chamber for a predetermined part of the turbocharger; and a jacket surrounding the turbocharger housing, the jacket being arranged in a spaced relationship relative to an outer surface of the turbocharger housing to define a fluid path about the outer surface of the turbocharger housing, the component having a cooling fluid inlet and a cooling fluid outlet.

6. The assembly as claimed in claim 5 , in which the cooling fluid outlet of the turbocharger housing of the component is in fluid communication with a cooling fluid inlet of the housing of the flame trap.

7. A compression ignition engine which includes the fluid input assembly as claimed in claim 4 .
