By Terry Edwards Last month we covered some of the differences between engines designed for aircraft and those that might be converted from auto use. Topics included propellers and speed-reduction units, cooling and lubrication systems. Complete Taekwondo Poomsae Pdf Printer.

This time we conclude with other systems that deserve careful attention when considering flight with an auto engine. Sparking Automobile ignition systems have progressed from points, condenser coil and distributor types, through solid-state switch systems, through integrated computer-controlled engine management systems. Modern engines will not run without all the sensors and controls, so when selecting a candidate engine, the ignition system should be included. Factors that are not considered by automobile engine designers are radio frequency (RF) shielding and high-altitude operation. Modern engines are known to emit RF interference that can be picked up with a VHF radio. GPS systems are also sensitive to stray interference. The high-voltage portion of the system is the most susceptible to dielectric breakdown at high altitudes due to the lower air pressure.

Aircraft engines have used sealed or pressurized magnetos to overcome this. Careful testing should reveal whether this is a problem. Some redundancy should be incorporated into the ignition system. FAR 33.37 for certified engines requires dual spark plugs per cylinder, a dual ignition system, and two separate electric circuits with separate sources of electrical energy, or a system of equivalent in-flight reliability.

While it may not be possible to have two spark plugs per cylinder due to cylinder-head design, other portions of the system can be made redundant. Hp Probook 4520s Drivers For Windows 7 32 Bit. The choice of fuel requires careful consideration. Table 1 illustrates the major differences between aviation and automotive gasolines. Comparing fuels. Avgas 100LL has a low and fixed vapor pressure all year to minimize vapor lock at all altitudes. Contrasting this, all grades of mogas vary the vapor pressure throughout the year to provide easy starting, but this leads to increased susceptibility to vapor locking.
