Title: David J Schouweiler, Jr: Innovator in Combustion Technology

Introduction

David J Schouweiler, Jr. is a notable inventor based in Minneapolis, MN (US). He has made significant contributions to the field of internal combustion engines, holding a total of 5 patents. His innovative designs focus on improving combustion efficiency and performance.

Latest Patents

One of his latest patents is for a fuel-stratified combustion chamber in a direct-injected internal combustion engine. This design features a combustion chamber bounded by a cylinder bore, a primary end, and a secondary end that reciprocates between a top dead center (TDC) position and a bottom dead center (BDC) position. The induction and exhaust ports are timed to facilitate the transfer of air into and gases from the chamber. The chamber achieves fuel stratification when the secondary end is positioned within a specific distance of the primary end. This stratification creates a central region, a perimeter region, and a transfer passageway between these regions. A fuel injector at the primary end injects fuel only into the central region prior to ignition, while the perimeter region pumps air into the central region, generating tumble turbulence. Combustion is initiated near TDC in the central region and concluded near TDC in the transfer passageway.
