Abstract
This paper presents a novel Variable Length Intake Manifold System (VLIMS) designed to enhance the performance and efficiency of internal combustion engines, with a focus on production vehicles. Unlike conventional cast intake manifolds that restrict geometric flexibility, VLIMS dynamically adjusts intake runner lengths to optimise torque and power across the entire RPM range. By incorporating advanced mechanisms for runner length control and smooth plenum movement, the system ensures uniform airflow while minimising eddy formation and resonance. The use of lightweight, nylon-filled polymers not only reduces production costs but also improves combustion efficiency through better swirl and air-fuel mixing. Modelling and simulation conducted in SolidWorks and GT-Suite validate the feasibility of VLIMS, demonstrating significant improvements in engine efficiency and fuel economy. Tailored for a KTM 390 engine, this system addresses the demand for a cost-effective, high-performance intake manifold solution suitable for mass production.
