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.
Basic Engine
  • Design and calculation of basic engine
  • Rigidity analysis and vibration optimization
  • Concepts for lightweight construction (magnesium, PA 6x…)
  • Cast and cast optimization
  • Valve operation design of variable valve operation (VVT / VVL)
Large Engines
hofer has been involved in the development of high power applications including large engines, transmissions and electrical drives since 20 years. Hybridising the driveline is our key competence, the combination of our expertise in e-mobility, software and electronics development as well as prototype manufacturing being crucial for achieving the short development times and best possible solutions.
