Engine overhaul

[BorisMulder]

To achieve this feature, I would suggest looking at these steps in order:

1. Petrol Engine

• create a new empty Feature in it's own directory in the repo
• see how the GT6 Diesel engine works by looking at the code.
• create an exact copy of the gt6 diesel engine named "Petrol Engine"
• for Ethanol and Petrol fuels, allow to burn them in the Petrol Engine but remove them from the Diesel Engine
• create the Filter machine part, add them for the materials Platinum, Palladium, Rhodium, Zinc
  • the recipe should be 8 fine wires in a loom with selector tag 8
  • change the fluid/item filter cover recipe to use one Zinc filter instead of 4 zinc foils
  • add a grate-like texture for the item with the correct color for the material
• create the Catalytic Converter part, add versions made of Platinum, Palladium, Rhodium
  • the recipe should be 1 small stainless steel fluid pipe, 2 filters of the corresponding material on the sides, and 1 hammer somewhere on the grid
• add the recipe for the Petrol Engine, which is the same as the GT6 Diesel Engine except the small pipe is replaced by a Palladium Catalytic Converter

2. Diesel Engine

• create an exact copy of the gt6 diesel engine named "Diesel Engine"
• see if you can add the same mechanism from the GT6 steam engine to it, causing it to start at low efficiency (25%) and going up with 1% every second up until 100%. Decreased efficiency should cause greater fuel consumption rather than lower energy output.
• replace the white square by a colored square that's green at 25-49% efficiency, yellow at 50-74%, orange at 75-99%, and red at 100%. Both while stationary (always green) and while running (optionally animated if you find out that's not too hard to do).
• allow Kerosine, Diesel and Fuel Oil to be burned in the new Diesel Engine, but no longer in the old gt6 diesel engine. Increase their energy value by 50% to allow them to compete with petrol.
• add the recipe for the Diesel Engine, which is the same as the GT6 Diesel Engine except the small pipe is replaced by a Platinum Catalytic Converter
• Disable the old Gt6 diesel engine in the recipe, in NEI, and in the NEI recipes for fuel burning.

3. Large Gas Turbine

• Change the recipe so it requires a Rhodium Catalytic Converter.

4 New Fuels

• Add a mixer recipe for 15L Petrol + 85L Ethanol = 100L "E85 fuel". this fuel should have an energy value (GU/L) greater than that of the sum of its parts divided by the ratio, and can be burned in the Petrol Engine. Maybe 25% higher, but do factor in the energy cost of the mixer so that does not become too expensive.
• same for 95L Petrol + 5L Ethanol = 100L "Euro 95". Same rule applies about energy value.
• Add Bio Diesel:
  • mixer recipes: 0 NaOH (catalyst) + 3U ethanol + 10U plant oil (e.g. seed oil, nut oil, etc.) = 1U glycerol + 12U Biodiesel
  • same energy value of Diesel
  • burn it in diesel engine
