Atom has a unique experience in designing different powertrains; combustion engines, hybrid and electric solutions.
By deploying the latest in CAE tools like topology optimization, FEA, CFD, multi body simulation, modal and thermal analysis- the development time can be extremely effective.
Atom can assist at any stage during the powertrain development.
Atom has the experience to design different types of combustion engines and can handle any engine design projects. Atom has so far been responsible for ground up engine designs in these configurations:
1-cylinder optical research
3-cylinder turbocharged
6-cylinder naturally aspirated
8-cylinder naturally aspirated and turbocharged
9-cylinder naturally aspirated
12-cylinder naturally aspirated
Design of Engine Components
Cylinder Head Design
Atom started as a cylinder head porting and dyno company to achieve maximum performance. The cylinder head design has to give the needed performance and at the same time provide high efficiency and low emissions. Atom has been able to fulfill these needs by utilizing innovative solutions to combine efficient combustion with extreme BMEP levels.
Atom has the experience of designing:
High pressure optical combustion engines
Turbocharged PPC and HCCI engines
Naturally aspirated racing engines, 2-stroke and 4-stroke
Turbocharged 2-stroke and 4-stroke engines
Camless engines
Engine Block
Atom was a pioneer in designing fully machined engine blocks. The billet engine block is perfect for prototypes and can be made in a variety of alloys, especially important when the time frame is short.

Crankshaft Design
Crankshaft design is truly a specialty at Atom and the foundation for a successful engine design. The design has to handle many aspects like weight, engine balance, lubrication needs, fatigue properties and manufacturing feasibility. Having done a variety of engine types and successful designs- Atom can do almost anything in this area.
