What do you think about the future car

Silver Pilate: That is very interesting. I haven't heard of that technology yet.

On the propane issue. The main disadvantages are as follows:

- It is a gaseous fuel and delivery is not as efficient, because it is not in liquid form.
- Propane tends to wash oil from the interior engine surface. This is more evident in 2-Strokes, but to a much lesser degree it still occurs in 4-strokes.

The advantages are:

- It has a high octane number which allows a higher compression ratio, hence it is more efficient. RON = 112 MON = 97
- Heating value is 46 MJ/kg, which is higher than gasoline's 40 MJ/kg
- It is stored as a liquid at ambient temperatures and relatively low pressures (100's of psi, not thousands)



However, Hydrogen is probably the fuel of the future, b/c:

- Low emission of hydrocarbons and carbon monoxide
- Readily available (as long as clean electric power is available)
- High energy content (120 MJ/kg)

The disadvantages of Hydrogen are as follows:

- It is a heavy fuel to store.
- Storage as a liquid requires very high pressure and very low temperatures
- Need a sealed fuel system
- Right now b/c of the infrastructure the cost would be high
- It uses a very high flame temperature, so NOx formation is greater
- It is very easily ignited, which can obviously be dangerous

It will be interesting to see what happens. As long as Mustangs stay Fast, RWD, and have a boat load of Torque, I'll probably be happy.
