Climbers who discovered the body of Mallory on Mount Everest have sent a tissue sample for testing to prove conclusively the remains were those of the British explorer lost in 1924, an expedition official said on Tuesday.
ENGINE RUN-ON, DIESELING -- RO-101. DIESELING, that nasty tendency of an engine to continue to run on, coughing and sputtering, after the ignition is turned off and there is no more spark. Run-on by dieseling is caused by fuel in engine igniting without spark. Possible explanations: a.) Running winter fuel in warm weather.
Here is the process of the engine. Intake, The fuel/air mixture is first drawn into the crankcase by the vacuum created during the upward stroke of the piston. The illustrated engine features a poppet intake valve, however many engines use a rotary value incorporated into the crankshaft. During the downward stroke the poppet valve is forced closed by the increased crankcase pressure. The fuel mixture is then compressed in the crankcase during the remainder of the stroke.
