ENGINEERING SERVICES

DESIGN
  • Mechanical design of parts and assemblies for internal combustion engines, racing machines (two or four wheeled) and mechanical systems.

  • Solid modelling with a 'design for manufacture' approach.

  • Extensive skills in surface modelling to provide A-class quality surfaces.

  • Engineering drawings produced using Geometric Dimensioning and Tolerancing techniques.

PROTOTYPE & REVERSE ENGINEERING
  • Rapid prototype; product visualisation of parts and assembly mock-ups.

  • First off prototype parts and assemblies.

  • Reverse engineering and inspection techniques; CMM, laser scanning and CT scanning - utilising a network of companies that work in partnership with Dunbar Race Engineering Ltd

ANALYSIS
  • Engineering analysis services for specific mechanical problems/challenges.

  • During the design process analysis is targeted to ensure designs are fit for purpose.

  • Analysis can take several forms, hand calculations, extensive use of excel, or Finite Element Analysis. 

PROJECT LEADERSHIP

Engaging with Dunbar Race Engineering Ltd for engineering services is a two way process. It's about working closely with the client to understand their requirements, having documented design reviews and concise communication. From concept design through to prototype manufacture Dunbar Race Engineering Ltd will manage your project to achieve your aims and deliver excellent engineering.

PREVIOUS PROJECTS

Piston & Rod Reverse Engineering
Reverse engineering of historic piston and connecting rod.
Then redesigned to increase piston diameter by 2mm and modernise the design to increase fatigue life.
IC Engine - Gas Exchange
Top end layout and design of gas exchange package for a 4-valve per cylinder racing engine. Surface modelling and analysis of ports, combustion chamber and piston crown.
Billet Cambox
Evolution of an existing cambox design for a single cylinder racing engine to incorporate new valve train design. Machine from solid cambox, which had originally been a casting.
Two Storke Crank Redesign
Reverse engineering of a Honda RS250 (NX5 / NXA) crank assembly. Crank webs were redesigned for small batch manufacture while maintaining the same mass and CofG.
Engineering analysis was comleted and the manufacturing process defined.
This project was halted due to manufacturing cost exceeding what could be marketed.
Airbox CFD Analysis
Airbox CFD analysis to examine the flow and mixing of air with natural gas for a steady state generator engine. Using Fluent CFD package.
IC Engine Gas Exchange Analysis
Gas exchange analysis of a naturally aspirated V5 990cc racing engine.
This was done using AVL Boost 1D solver.
