Embodiment Construction

[0032] Although the present invention is capable of various modifications and alternative forms, specific embodiments have been illustrated in the drawings by way of example and described in detail below. However, it is not intended to limit the invention to the specific embodiments described. On the contrary, the present invention is intended to cover all modifications, equivalent structures, and alternatives falling within the scope of the present invention defined by the appended claims.

[0033] Figure 1-Figure 4 A two-stage turbocharging system according to the principles of the present disclosure is depicted. Generally, the system 10 includes a VEE-structure engine 12, a low-pressure turbocharger 14, an intermediate air cooler 16 (or intercooler 16), a high-pressure turbocharger 18, a charge air cooler 20 (or after-cooling 器20) and exhaust manifold 22 ( Figure 7A-Figure 7B ). As described in more detail below, turbochargers 14, 18, coolers 16, 20, and exhaust manifold 22...

Abstract

The invention relates to an exhaust manifold for a two-stage engine charge air system. An exhaust manifold is provided comprising a first log comprising a plurality of inlet segments each having a pair of inlet ports configured to receive exhaust gas from a pair of cylinders of an engine, a second log comprising a plurality of inlet segments each having a pair of inlet ports configured to receive exhaust gas from a pair of cylinders of the engine, and a collector coupled to the logs, the collector comprising a first pair of intake openings configured to receive exhaust gas from the first log, a second pair of intake openings configured to receive exhaust gas from the second log and an outlet configured to route the exhaust gas to a turbocharger, wherein the first pair of intake openings are coupled to a pair of bellows of the first log, each of the pair of bellows being coupled to an inlet segment.

Description

Technical field [0001] The present invention relates generally to a charge air system, and more specifically to an exhaust manifold for a two-stage engine charge air system packaged in a VEE on a spark ignition engine. Background technique [0002] Typically, vehicle engines and engines used in other applications are housed in an engine compartment or other types of accessories. It is often a challenge to package the engine and various components on the engine (for example, turbocharger, aftercooler, etc.) in the small space provided. [0003] In many applications, some engine components are installed adjacent to the side of the engine. However, the more engine accessories or parts installed along the side of the engine, the more difficult it is to access the engine for activities such as maintenance. [0004] In VEE-build engines, it may be desirable to install certain engine components "in the VEE" along the top of the engine. Some engine designs include aftercooler turbo and wh...
