COMBUSTION IN PISTON ENGINES (HB)

Combustion in Piston Engines presents the technique of pressure diagnostics to measure the fuel consumption in an engine cylinder and to monitor the operation of micro-electronic systems for its control. It provides a recipe for bridging the gap between the hydrocarbon-fed combustion technology of automotive powerplants of today and electro-magnetic technologies of the future. The author proposes and introduces a model for the design of a MECC (micro-electronically controlled combustion) systems to modulate combustion in engine cylinders. This system yields significant reduction in the formation of pollutants and the consumption of fuel, so that, eventually, emissions using any clean hydrocarbon fuel will be acceptable and gas mileage could be doubled.

Upon a synthesis of the technology of Combustion in Piston Engines, its past, present and future, the book provides a recipe for its advancement. Engines of the future are visualized as featuring distributed combustion (vid. photograph on the front cover) executed by means of PJI&I (Pulse Jet Injection and Ignition) actuators, modulated by MECC (Micro-Electronically Controlled Combustion) systems in response to signals provided by pressure sensors. To assist in the development of such engines, the book provides the method of pressure diagnostics – an analytical technique for interpreting the signal provided by a pressure sensor to assess the effectiveness with which fuel is utilized in an engine cylinder, and to monitor the operation of MECC in optimizing the performance of a PJI&I system. It is on this basis that a demonstration is produced of a representative car engine, for which, by the use of these systems, the formation of pollutants can be reduced by orders of magnitude, while the consumption of fuel is halved.
