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 […]


DC Non-Transferred Plasma Torch

October 1st, 2017 plasma-torch-simulation-vizglow

VizSpark is used to model a non-transferred direct current plasma torch in pure argon gas assuming axi-symmetry along the central axis.  A steady state thermal plasma with temperatures from 15-20,000 Kelvin forms a supersonic, under expanded jet in the ambient region with visible Mach diamonds. Plasma torches are devices that produce a steady thermal plasma jet.  There are many applications for plasma torches including arc cutting, wielding, plasma spraying and waste treatment. A plasma torch […]


Sparkplug with Cross-Flow and Electrode Ablation

June 1st, 2017 spark-plug-thermal-arc-simulation-vizspark

The VizSpark software is used to perform a 2-D simulation of a model spark plug channel with cross-flow. Coupling between arc physics and conjugate heat transfer to the electrode was performed. The ability to predict spark restrike events was also demonstrated. Furthermore, an estimate of electrode ablation is also made. The spark plug has been a reliable source of ignition for well over 100 years.  The ignition source plays a pivotal role in the efficiency […]
