Esgee to Present at SAE World Congress 2019: High-Fidelity Numerical Modeling of Spark Plug Erosion

April 8th, 2019

Esgee Technologies will present “High-Fidelity Numerical Modeling of Spark Plug Erosion” at the SAE International World Congress Experience 2019, April 9-11, at the Cobo Center in Detroit, Michigan. Abstract Spark plug erosion is critical in determining the overall efficiency of a spark ignition engine. Over its lifetime, a spark plug is subject to millions of firings. Each spark event results in material erosion due to several mechanisms such as melting, vaporization, sputtering and oxidation. With electrode […]


Esgee to Present at SAE World Congress 2019: Simulation of Spark-Initiated Combustion

April 8th, 2019

Esgee Technologies will present “Simulation of Spark-Initiated Combustion” at the SAE International World Congress Experience 2019, April 9-11, at the Cobo Center in Detroit, Michigan. Abstract There has been an increased interest in understanding the initial stages of flame kernel formation in internal combustion engines as it offers a potential way of improving their thermal efficiency. For spark-ignited engines, the dynamics that govern the initial spark and its transition into a flame kernel play an important […]


Esgee to Present at IAV in Berlin: Spark Plug Life

November 27th, 2018

Esgee Technologies is excited to attend the International Conference on Ignition Systems for Gasoline Engines next week, December 6-7, in Berlin, Germany. Join Esgee Tech’s Doug Breden for his talk on “Numerical Modelling of Electrode Ablation for Spark Plug Lifetime Prediction.” He’ll discuss how high-fidelity arc simulation, combined with dynamic surface deformation and timescale acceleration techniques, can be used to effectively predict spark plug life. This capability reduces the need for field testing, expands design […]


Esgee to Present at SAE World Congress 2018: Spark Plug Life Simulation

March 5th, 2018

  Esgee Technologies will present “Modeling of Electrode Erosion for Prediction of Spark Plug Lifetime” at the SAE International World Congress Experience 2018, April 10-12, at the Cobo Center in Detroit, Michigan.   Abstract: The maximum lifetime of a spark plug is limited by electrode erosion.  Over the course of millions of repeated sparking events, the electrode material ablates and the electrode gap increases which degrades performance.  Once a critical gap is reached, the spark […]


Esgee to Present at SAE World Congress 2018: Arc Quenching in EV Relays

March 5th, 2018

  Esgee Technologies will present “Simulation of Arc Quenching in Hermetically Sealed Electric Vehicle Relays” at the SAE International World Congress Experience 2018, April 10-12, at the Cobo Center in Detroit, Michigan.   Abstract High-voltage relays perform a key role in determining safety and protections of Electric Vehicles(EV)/ hybrid automotive systems. The primary function of a high voltage relay is to mechanically separate electrodes under a short circuit situation, and isolate the motor drive electronics […]
