One or more components in an Internal Combustion Engine and method of manufacture thereof
Problem Statement

The increasing number of vehicles has led to a higher demand for fuel, making fuel consumption a critical issue. Traditional methods have focused on lightweighting autobodies, but there is a need to reduce the weight of engine components to further enhance fuel efficiency and reduce emissions.

Abstract

The invention pertains to lightweighting engine components such as the cylinder head, connecting rod, and cylinder liner in an internal combustion engine. This technology aims to reduce the overall weight of the engine, thus enhancing fuel efficiency and reducing emissions. By redesigning these components to be manufacturable using sheet metal, significant weight reduction is achieved while maintaining performance.

Uniqueness of the Solution
  • Redesign of Engine Components: Components like the cylinder head, connecting rod, and cylinder liner are redesigned using sheet metal 
  • Weight Reduction: Achieves up to a 25% reduction in weight for components such as the connecting rod 
  • Manufacturing Techniques: Utilizes processes such as drawing, welding, and Metal Injection Molding (MIM) for manufacturing the components 
  • Cooling System: Integrated fins and liquid-filled gaps enhances engine cooling efficiency without the need for additional radiators 
  • Material Selection: Use of materials like Al-SiC, pure aluminum, and aluminum alloys for high thermal conductivity and lightweight properties 
  • Enhanced Fuel Efficiency: Lighter engine components contribute to lower fuel consumption and reduced emissions 
  • Cost-Effective Manufacturing: The use of sheet metal and advanced manufacturing processes reduces material and production costs
Prototype Details

Prototypes include redesigned connecting rods, piston heads, and cylinder liners. These prototypes have been tested to ensure they meet the required performance standards under both static and dynamic conditions.

Current Status of Technology

The technology has been developed and prototyped, demonstrating significant weight reduction and performance improvements in engine components. Further refinement and large-scale manufacturing adaptations are underway.
