[This] engine is conventional, though novel. Don't expect high efficiency.
Losses in Crankshaft
On Oct. 5, 2005, former NEC member, Douglas Mann wrote:
ANY engine that has a standard crankshaft rod type system by design will have very poor efficiency. The percent of force that the effective cylinder applies to the piston that can be converted to toqure is less than 20% max point with an over all mean of less than 7%. This factor is why standard engine designs have not been able to improve. Rotory design offer some improvment with other problems but even then most design convert less than 25% of the applied force to the load. Turbo engines can convert 50% of applyed force but the open combustion is the problem there.
My engine called the Dmannd Engine has a mean conversion rate of over 90%. It is a very advanced form of the Bourke engine design. Being a two cylinder op engine with yoke drive crank system.
On Oct. 7, 2005, NEC member, Ken Rauen responded to Douglas Mann:
- Nonsense. Engines have been tested by the thousands that achieve 30% absolute efficiency. This is far above your 7 and 20% mechanical transfer figures.
