Closeup model of the AT IC motor 1 (gasoline version). The AT IC 1 motor is a line motor, double-overhead cam motor, with 16 valves, and 4 cylinders (L4, DOHC, 16V). The model is fitted with 2 fuel tanks, one with nitrous oxide, the other with ethanol. The nitrous oxide tank has a chamber filled with oil around it and heater coils, aswell as an air pipe that can distrubite cold to the oil. Depending on the ambient temperature, one of both may be activated to heat or cool the oil (and with it, the nitrous oxide inside the tank) to a temperature that is high enough to allow deflagration when it arrives at the combustion chamber. Nitrous oxide is said to deflagrate somewhere around 600° Fahrenheit (315°Celsius), so the 17 bar (5 bar + 12 bar from compression by piston) and the 1000°C should be enough to allow it to deflagrate. Do note that the nitrous oxide can only be used when the motor has warmed up, which means that the motor should first run a short while on ethanol. The motor is also fitted with: an SU-type carburetor (based on the SU HS6), a dynamo, a magneto ignition (which creates the spark at the spark plugs), a centrifugal pump, an oil pump (gear pump), a simplified thermostat, and fuel injectors. The oil pump pumps the oil around, ensuring suitable lubrication of the moving parts. Note that the cam rods, springs, ... and the buildup of the motor is designed in such a way that everything can be easily assembled/disassembled. The oil system used is a wet sump system. The diaphragm pump for pumping the ethanol is not essential, since the ethanol fuel supply is gravity-powered anyway. The nitrous oxide is directly injected (direct injection/DI) using the fuel injectors. The air pipe connected to the carburetor is fitted with valves to allow regulating the air stream, just before the carburetor, an air meter is placed for precise measurement and automated control using a PCB. Before the branching of the manifold pipe into 4 pipes, another valve is present to regulate the air+gasoline flow into the combustion chambers. The valve can also be closed when the motor switches to nitrous oxide. For details on the water circulation, see the IC_1_setups model and text. See the 'Purchasing_the_models' link at appropedia's AT_CAD_Team for additional information on the model. The system was inspired on the nitrous-only design built by Trevor Langfield of NOSwizards.
