Engine Building

HWA AG can be implement the following projects in a very short time with a high technical and personal standard:

  • Development, design and calculation of high-performance engines for motor racing and road sports vehicles
  • Construction of test and competition engines
  • Production of prototype and small series engines
  • Quality management according to ISO 9001:2008
  • Servicing and maintenance of engines after delivery
  • Overhaul and repair of complete engines
  • Component development on several flexibly structured component test stands

Project stages: engine development

The following project stages is an example for an engine development:

  • Customer discussion re. wishes and feasibility of engine development
  • Discussion and definition of specification on the basis of customer requirements
  • Preparation of feasibility studies and project plans incl. timetabling and costs
  • Calculation and design of engine components using modern computer programs
  • Networked simulation calculations for loading changes and mechanics
  • Manufacture of prototype engines with rapid prototyping cast components for preliminary investigations
  • Construction of first test samples
  • Commissioning of test engines on engine test stand
  • Carrying out test stand investigations as per specification
  • Optimising performance, consumption and durability using automated measurement cycles
  • Provision and support of applied prototype engines for initial vehicle testing
  • Project management to comply with defined timetable and budget
  • Carrying out the necessary certification tests
  • Preparing parts lists and manufacturing plans for the production of the engines
  • Production of engines in engine production incl. documentation
  • Quality assurance of completed engines re. performance and function on test stands

Engine Test Dynos

The Engine Test Dynos consist of

  • 3 engine dynos for combustion engines with up to 9000 rpm and a power of up to 830 kW. Static and transient testing possible.
  • 1 powertrain dyno for development and endurance testing of complete powertrains with up to 800 kW brake power. High-dynamic simulation of test tracks. Optionally input over electric motors with a power of up to 960 kW for development of gearboxes.
  • Several test rigs for selective development of engine components (cylinder head, valve train, oil pumps, water pumps etc.)

To achieve a high measuring quality, various development tools are used, as for example

  • Flexible automation systems with different interfaces to car systems
  • Modern software for engine application
  • Conditioned combustion air regarding temperature, humidity and pressure, for static tests as well as or transient use.
  • Comprehensive measurement equipment to record all engine-relevant data
