Engine & Systems
hofer combines all competencies for the development and construction of entire drive units and the controls to operate them, as well as functional and calibrational activities.
Focus on:
- Concept development, engine construction and engine application
- Lightweight construction concepts, cast magnesium and cast optimization
- Cylinder head and valve operation components as well as camshaft phasers
- Construction and operation of units for use with alternative fuels
- Retrofitting of units for gas operation
- Retrofitting of units for seawater-proof operation
From concept to series: elaboration of function requirements, concept CAD and FEM simulation, prototype set-up and validation all the way to the testing of units under customer-premise-related conditions.
