Revision as of 20:26, 30 July 2022
Selection
OSE's 2020 choice for an engine is the Poulan 19 hp x4 for 74 hp - [1]
Gas
The threshold for relatively inexpensive engines is 19 hp.
- 27 hp - $980 - $36/hp - [2]. And needs muffler.
- 24 hp - $870 - $36/hp [3]
- 22 hp - Briggs - $29/hp - [4]
- 20 hp - Kohler $700 - $35/hp + muffler - [5]
- 19 hp Poulan - - $20.5/hp - $390 - [6]
- 16 hp - $350 - Poulan - [7]. No gas pump, gravity feed gas. But, doesn't come with muffler.
Has 15A charging. Muffler - [8] - 16hp - $330 - Duromax, $20.6/hp - [9]
- 7 hp - $159 - $22/hp - but no electric start - [10]
- 18hp Duromax $18/hp - has muffler, but not charging
- such as for a fan - [11]
Diesel
- 30 hp Kubota $5000 - $166/hp [12]
- 33 hp Kubota - $6500 [13]
- 65 HP - $6300 - $100/hp [14]
- 200 hp - $55/HP - $11k - Cummins - [15]
- 360 HP Mack used - $10/HP - $3600
Considerations
- Until an open source engine becomes a reality, engine repair is expensive. $50/hr, easily comes to the new engine price for the $300 gas engine. This indicates that small engines are essentially disposable goods.
- For the large diesel engine, parts are expensive.
- Until the advent of the open source diesel engine, engine costs remain 10x as high as they should be.
- Until the OS engine, disposable engines are a suboptimal but acceptable strategy to keep costs of engine systems low.
- It is an immediate priority of OSE to develop open source small engines, $11B market (see Market Size) and larger ones are more like 200 billion
Engine Links
- 500 &U 1000 hour lifetime for small engines - [16]
- 2000-4000 year life of car engines [17] - 150k miles
- Tractor engines - 5-10k hours [18]
- Pellet-fired stirling engine buggy - see PDF file
- Several links to various engine types including Sterling, Wankel, Steam, etc. [19].
