Two-stage engine charge air system with branch conduits

An aftercooler is provided comprising a housing, an outlet diverter coupled to the housing and having an outlet port, and an inlet diffuser comprising a forward wall having a peripheral rim coupled to the housing, an upper wall connected to the forward wall, a lower wall connected to the forward wall, a first side wall connected to the upper wall and the lower wall and having a first end disposed adjacent the peripheral rim and a second end disposed adjacent an inlet port of the inlet diffuser, a second side wall connected to the upper wall and the lower wall and having a first end disposed adjacent the peripheral rim and a second end disposed adjacent the inlet port, and a plurality of fins disposed within an interior volume of the inlet diffuser collectively distributing air across an outlet opening of the inlet diffuser for delivery to the housing.

Inlet diffusers for a two-stage engine charge air system

A lobed exhaust diffuser apparatus, system, and method configured to cool exhaust gases from an internal combustion engine comprises a diffuser having a proximal end, configured to receive exhaust gases from the engine, and a distal end, configured to expel the exhaust gases into the atmosphere. A plurality of lobes are disposed on the distal end such that at least a portion of the exhaust gases pass through the lobes, increasing the interaction surface area between the exhaust gases and the atmosphere, allowing for more rapid diffusion and entrainment between exhaust gases and atmospheric gases, resulting in more rapid cooling of the exhaust gases.

Lobed exhaust diffuser apparatus, system, and method

An engine is provided which includes various precise configuration parameters, including dimensions, shape and/or relative positioning of the combustion chamber features, resulting in a combustion process minimizing NOx emissions and particulates. The combustion chamber includes one or more of the following: a spray angle relative to an inner bowl floor angle; a vertical distance from the tip of the piston bowl to the injection orifices; a number of injection orifices; a swirl ratio; a vertical distance from the injection orifices to an inner face of the cylinder head; a radius of curvature of an outer bowl section; chamfer with dimensional parameters; and a transition radius.

Internal combustion engine producing low emissions

An engine is provided which includes various precise configuration parameters, including dimensions, shape and/or relative positioning of the combustion chamber features, resulting in a combustion process minimizing NOx emissions and particulates. The combustion chamber includes a spray angle relative to an inner bowl floor angle that maximizes the amount of fuel in contact with the inner bowl, in combination with one or more of the following: a vertical distance from the tip of the piston bowl to the injection orifices; a number of injection orifices; a swirl ratio; a vertical distance from the injection orifices to an inner face of the cylinder head; a distance from the piston top surface to the cylinder head; a radius of curvature of an outer bowl section; a radius of curvature at an edge of the piston bowl; a ratio of the piston bowl diameter to the cylinder diameter; and the cylinder diameter.
