Ignition systems

I know you've "heard it all" when it comes to ignition enhancements that are supposed to increase power, mileage and decrease emissions. You've seen special ignition modules, magical plugs, special wires and fancy distributor caps. They cost a fortune and promise you the moon.

Pilot Ignition System On a pilot ignition oven, there is a pilot which is an actual gas flame although very small in the oven. What happens in this system is that the pilot stays lit all the time and when the oven thermostat is turned on, the pilot flame extends gets bigger to envelope the thermocouple bulb of the oven safety valve.

The thermostat controls gas flow to both the pilot and to the oven safety valve. Once the oven safety valve's thermocouple senses appropriate heat, the safety valve opens to allow gas flow to the oven burner where the pilot flame ignites the gas.

Oven not heating On a pilot ignition Ignition systems the pilot flame must be lit for the Ignition systems burner to receive gas. The oven control knob may have to continue to be held in for up to a minute after the pilot has been re-lit. If the pilot IS lit but the oven burner is not lighting, the pilot flame will need to be inspected as the thermostat is turned on.

If the pilot is not extending when the thermostat is tuned to ON, the oven thermostat may be defective. If the pilot is extending but the oven gas valve is not opening, that oven safety valve may be defective or its sensor bulb may be out of position on the pilot or just dirty causing it to not sense the proper temperature of the pilot flame.

A dirty pilot can also cause a reduced size pilot flame so the oven safety valve can not sense the proper temperature to open. Observations necessary to diagnose problems Is the pilot lit?

Does the pilot extend get bigger when the thermostat is turned on? Is the safety valve's sensor properly mounted in the pilot? It was a fairly reliable setup. On this style of ignition system there is a constantly burning pilot similar to the pilot ignition system described above but the pilot flame does not change in size as the control is turned on.

This system uses a 'flame switch' to detect that the pilot is lit instead of a safety valve like on the pilot ignition system. The thermostat on such a system is just electrical and does not alter gas flow to the oven.

The pilot flame should heat the tip of the flame switch's sensor bulb to a red colour. If the flame switch detects sufficient heat on its sensor bulb at the pilot, it will close an electrical contact in its base. Once the thermostat is turned on, current will be allowed to flow through the flame switch to the oven valve to allow it to open.

If the flame switch's sensor is not heated sufficiently, the electrical contacts of the flame switch would remain open preventing any power from reaching the oven valve which in turn would prevent gas from flowing to the oven burner.

In a properly operating system it should usually only take in the area of seconds for the oven burner to receive gas and to light. Oven burner not getting gas The pilot must be lit before electrical current will flow through the flame switch to the oven gas valve to allow gas to the oven burner.Electronic Ignitions systems for 4 and 6 cyclinder aircraft.

Spark Plugs: How would you like to be shut in a chamber with temperatures of up to °C, splashed with petrol and given a 30, volt electric shock 25 times a second, and be subjected to pressures 50 times greater than normal atmosphere? The document you're reading here (and below) is primarily about the Vision Electronics with emphasis on solving ignition problems.

The distributor unit consists of a metal bowl containing a central shaft, which is usually driven directly by the camshaft or, sometimes, by the crankshaft.
