Closed loop diesel engine control
TLDR
In this article, a method and apparatus for achieving optimized efficiency combustion in a diesel internal combustion engine utilizes a cylinder pressure detector which measures peak cylinder pressure relative to crankshaft timing and compares it with a speed-load-timing map comprising several engine parameters including engine speed and engine load in order to compensate for various unknown combustion characteristics of the fuels to be used in compression ignition engines, and automatically adjusts fuel injection timing for optimum efficiency.Abstract:

Ignition systems for internal combustion engines
TL;DR: In this paper, the advance and retard of the spark ignition in an internal combustion engine are achieved by generating two series of pulses in synchronism with the engine using one series as a reference for maximum advance and the other series to operate a counter to count down the requisite number of pulses beyond the maximum advance point before the spark is initiated, the count of the counter being varied from a computer in accordance with speed and load on the engine.
