Faqhome / SC-1 vs competitor research single cylinder engines?

By wozander@gmail.com, on March 25th, 2013

Large cost advantage
Replacement bearings / seals / bolts / spare-parts multi-source and reasonable
Ease of build-up / teardown
- Engine features horizontally split, “Dutch dowel”, o-ringed construction; requires no gaskets or special tools
- Uses conventional split bearings and standard seals
Balance mechanism
- Low friction and Not rpm limited
- Simple bolt on weights to change balance
- No balance shaft inertia bending, gear drive, noise and torsional issues
- Balance forces are resolved in crank rather than through bearings lowering friction losses
All oil/water/electric/fuel ancillaries are remote
- No parasitic losses of ancillaries (and their variances) affecting brake data
- Initial warm ups can happen without engine rotation
- Dry sump gives:
  - Tighter control of oil temp than conventional wet sumps
  - Vacuum ability for lowered windage losses
Cylinder Head Adapter
- Wet liner
  - Supported round by adapter at high loads
  - Cooling passage CFD optimized
- Large deck can use a 4 cylinder head, firing cylinder #2
- Short deck for custom single heads and better access
