Problems solved by technology

The limiting factor in the injection molding process is the processing (such as cooling) time, which depends significantly on the spatial dimensions (such as thickness) of the shell. Therefore, if the shell thickness at certain points is large, the manufacturing has Runners in thicker sections can be inefficient and cost-effective
Furthermore, the layer stacking of the shell may result in welded thick sections in the shell, which add excess weight to the intake manifold in addition to increasing manufacturing costs

Embodiment Construction

[0016] The following description relates to systems and methods for a modified intake manifold of an engine that includes a modified intake runner having negative ribs. figure 1 An example engine system including a modified intake runner coupled to each engine cylinder is shown in . The intake manifold of the engine includes an air chamber and a plurality of intake runners positioned between the air chamber and a corresponding intake port for each cylinder. figure 2 A single cylinder of an engine system including a modified intake runner is shown in . A section of each intake runner may include negative ribs formed on the façade, such as image 3 shown in. Figure 4 to Figure 6 More details are shown of the interior portion of the intake runner, the interior portion including a recess formed below the facade, the recess having negative ribs that promote airflow through the intake runner.

Abstract

The present disclosure provides an engine intake manifold with internal ribs. Methods and systems are provided for a modified intake runner including ribs in an airflow direction. In one example, a system may include an intake manifold adapted to be coupled to an intake passage via an intake runner. Inside the intake runner, a plurality of negative ribs may be arranged in the direction of airflow on the facade of the interior portion.

Description

technical field [0001] The present description generally relates to methods and systems for modified intake runners that include ribs in the direction of airflow. Background technique [0002] In an internal combustion engine, air is introduced into the intake manifold via an intake throttle. The intake manifold usually consists of air chambers and intake runners. The intake runner also directs airflow into the engine cylinder from a first end of the intake runner proximate the plenum through a second end of the intake runner proximate the cylinder. Such intake runners are shaped to improve flow pressure and airflow dynamics through the runners. In order to obtain the desired shape of the air flow through the intake runners, multiple moulded parts (housings) are welded together. [0003] Various methods have been developed to improve flow dynamics in engine intake manifolds. An example method is shown by Kulkarni in US 8,955,485. Among other things, Kulkarni introduced ...
