Title: Innovations by Steven G Smith

Introduction

Steven G Smith is an accomplished inventor based in Roseville, MN (US). He has made significant contributions to the field of engine diagnostics, holding 2 patents that enhance the understanding and performance of internal combustion engines.

Latest Patents

One of his latest patents is titled "System and method for diagnosing output power of an internal combustion engine." This invention includes means for diagnosing potential causes of low engine output power or torque and methods for estimating actual engine output power or torque. The process begins by investigating the authenticity of low engine output power conditions. If a low output power condition is confirmed, a zero fueling engine cranking test is performed to check the relative compression values of each cylinder. If issues are found, they are addressed by service personnel. If the problem persists, a snap-throttle cylinder balancing test is conducted to balance the power contribution from each cylinder. Finally, a road test is performed to estimate the actual engine output power for comparison with the rated output over a range of engine speeds.

Another notable patent is the "System and method for engine cylinder power diagnosis by cylinder(s)." This invention measures individual cylinder power contribution by cutting out individual cylinders of a multi-cylinder engine and performing a snap-throttle test. During each test, engine speed versus time data is collected and stored. This data is then analyzed to calculate the power contribution from each cylinder using various methods, including least squares analysis or kinetic energy analysis.
