One of the objectives is to take parts to powder coat by tomorrow (March 11th 2015)
– Get every part that needs to be powder-coated
o Frame, Swing Arm, License Plate Holder, Battery Box and Cover, Oil Reservoir, Brake Covers.
o Color will be shiny black
o We won’t be powder coating the gas tank.
The two articles on Engine Combustion
– Heavy crude, light crude and sweet crude oil
o Heavy and light has to do with density
o Sweetness has to do with impurity—sulfur
– What we call gasoline is not really C8H18, but it’s in the middle of the distribution of the refining process
– 10% of crude oil gets turned into gasoline
– Cracking
o Thermal vs Catalytic
- Influences a lot about how much gasoline you will get in the end
– Octane reaction à exothermic, 44.4KJ/g for C8H18
– The air to fuel ratio (AFR) is 15 ~ 14.7
– Our engine displace = 200 cc, how much does 200cc of air weigh?
o .257 grams after stoichiometry
o fuel = (1 / 15) * .257 = .0171
o Thus, maximum energy release per explosion is 759 Joules
– After a series of calculations, at top engine speed, we have 50 explosions per second.
– Gasoline engines are about 1/3rd efficient
