AVL BOOST Hydsim

INJECTION SYSTEM SIMULATION

AVL BOOST™ Hydsim

BOOST™ Hydsim is a software tool for the dynamic analysis of non-stationary hydraulic and hydro-mechanical systems. It is based on the theory of one-dimensional fluid flow and vibration of multi-body systems. The main application area of BOOST™ Hydsim is the simulation of fuel injection.

AVL Approach

Historically, BOOST Hydsim has been developed for the simulation of diesel injection systems. Today, BOOST Hydsim is well suited for the modeling of gasoline, heavy oil, gas, alternative fuel injection etc. All types of common rail and other (e.g. unit, in-line pump) injection systems are covered. New applications such as hydraulic transmissions, valve trains and actuators have also been considered.
