Title: JangSu Lee: Innovator in Automotive Technology

Introduction

JangSu Lee is a prominent inventor based in Yongin, South Korea. He has made significant contributions to the automotive industry, particularly in the field of variable valve lift systems. With a total of 7 patents to his name, Lee continues to push the boundaries of automotive technology.

Latest Patents

One of his latest patents is a method for diagnosing and controlling a two-step exhaust variable valve lift (VVL) system. This innovative method involves a controlling device that acquires an operation state signal of a vehicle. When the vehicle is in the over-run state, the controlling device outputs a mode conversion signal for the two-step exhaust VVL system. An air mass sensor measures the air mass entering the engine, and the controlling device compares a predetermined prediction value of the air mass with the measured air mass. If the difference corresponds to a predetermined mode conversion comparing amount, the controlling device determines that the mode conversion is complete. Conversely, if the difference does not correspond, the system is deemed faulty, and a result is outputted.

Another notable patent is a method for calculating oxygen concentration in a combustion chamber. This method calculates the volume efficiency of the combustion chamber while the variable valve lift is in an on state. It also calculates the mass of internal EGR from the pressure and temperature of the exhaust manifold, providing valuable insights into combustion efficiency.
