Re: [St] Gas mileage, a new bike selling trend

[brettwilson21@xxxxxxx]

 Thats something that has always troubled me about the internal combustion engine. Essentiallly it hasnt changed much since it was invented. Some vehicles are less enfficient now than those that have gone before. I seem to recall reading of several engineers in the US and Europe that were quite miffed at the inefficient design, not only heat loss but also the conventional layout of piston/crank/cams. So far it seems the mass producers have resisted changing to another design or making the current design more efficient.

Bertt.





You have that right gasoline is a very energy dense fuel. There is no 
other fuel that is as easy to carry with anywhere near the density of 
gasoline.?


However with that being said, the current usage of gasoline in most 
Internal combustion engines is not efficient, as most of the 
combustion energy is lost as nothing but heat to exhaust. Most 
current engines struggle to be 30% efficient, between the heat lost 
and the incomplete combustion. I mean if combustion of the fuel was 
complete, the exhaust would be full of CO2 and H20 vapors with only a 
few traces of the dangerous emmissions. There would be no need for 
catalytic converters!?


That is why I'm keeping my eyes and ears on the technologies to 
reduce or utilize the heat and increase the efficiency of the system.?
