Engine Simulations

The Inwardly Opposed Diesel Engine

The inwardly opposed piston diesel engine was first optimized using TECAT Engineering's Opposed Piston Diesel Engine Simulation, OPDES. This is a two stroke, uniflow diesel engine with upstream supercharging, intercooling, turbo-charging and turbo-compounding. The engine simulation includes the following components: turbomachinery and manifold models, a wastegate model; an injection optimization algorithm, which is limited by both manifold pressure and in-cylinder pressure; peak torque searching algorithm; peak power searching algorithm; round, elliptic or square port design capability; and a thermal network model, which tracks energy distributions out to the coolant and oil. There are currently two working engine prototypes developed from OPDES specifications.
