The thermal ignition combustion system comprises means for providing walls defining an ignition chamber, the walls being made of a material having a thermal conductivity greater than 20 W/m.degree. C. and a specific heat greater than 480 J/kg.degree. C. with the ignition chamber being in constant communication with the main combustion chamber, means for maintaining the temperature of the walls above a threshold temperature capable of causing ignition of a fuel, and means for conducting fuel to the ignition chamber.

The disclosure illustrates a fuel mileage indicator which gives a dynamic reading of the fuel mileage for a vehicle powered by an internal combustion engine. As a result it indicates to the driver whether he is driving efficiently and is conserving fuel. The device consists of a variable resistance device responsive to a fuel system parameter or other engine parameter which is proportional to engine fuel flow. This variable resistance device is connected in series with a generator having a D.C. voltage output directly proportional to vehicle speed. An ammeter indicates current through the circuit and is calibrated to give an output of miles per gallon.
