Q: Is the TITAN EXP Fuel Injection System certificated?
A: No. The TITAN EXP Fuel Injection System is not certificated at the present time. It is eligible for experimental aircraft.

Q: Does ECi intend to certificate the system?
A: The answer to that question will be determined by market demand.

Q: Is the system compatible with unleaded gas?
A: Yes. However, the owner/operator must determine the compatibility of unleaded fuels with the requirements of the engine and installation. The materials in the valves, valve seats and valve guides of the ECi TITAN KitEngineâ„¢ cylinders require the use of 100LL aviation fuel for initial break-in, approximately the first 25 hours of engine operation. ECi does NOT recommend the use of current unleaded fuel in any engine having a compression ratio in excess of 8.5:1, in any engine subject to operation in excess of rated RPM nor in engines that are supercharged.

Q: Can the TITAN EXP Fuel Injection System be overhauled in the field?
A: Yes. Overhaul data and competitively priced replacement parts will be available. In addition, a Calibration Kit is available from ECi.

Q: Will all TITAN KitEngines come equipped with the TITAN EXP Fuel Injection System?
A: No. This will be a kit option.

Q: What type of pump does the system use?
A: A mechanically driven vane type fuel pump that operates at pressures up to 30 psi. The pump attaches to the accessory housing by means of an AN pad and is gear driven.

Q: Are the vane type fuel pump and the automotive diaphragm type fuel pump interchangeable on the same accessory case?
A: No, but soon you will be able to mount the fuel pump on the vacuum pump pad on those aircraft not using a vacuum pump.

Q: What happens if the pump fails?
A: The mechanical system is backed up by an electrically driven boost pump for engine starting and emergencies.

Q: Does it make any difference if the airplane has a high wing or a low wing?
A: No.

Q: How does the return fuel line work?
A: The outgoing and the return fuel lines are routed as a pair and are simultaneously controlled by a fuel selector valve manufactured by Andair Ltd. When the fuel selector valve is turned to the desired tank, fuel is taken from the tank and the excess fuel is returned to the same tank.

Q: Will the TITAN EXP Fuel Injection System only work with the TITAN EXP Cold Induction System?
A: No. TITAN EXP Fuel Injection System will work with any induction system currently on the market but enhances engine performance the most when used in conjunction with the TITAN EXP Cold Induction System.
