This chapter explores the importance of inspiration in leadership and its value in ensuring organizations thrive. The value of being inspired and inspiring others is examined, as well as the ways in which inspiration is created. Through real-life examples, autonomy, mastery, purpose and connection are deeply explored as the conditions necessary for ...

SAE Technical Paper Series, 2003
<div class="htmlview paragraph">A new “Traveling Spark Ignition” (TSI) system which, aided by a Lorentz force, propels a large plasma into the chamber of internal combustion engines, has been developed and tested on a single cylinder 4-stroke engine run on natural gas. Engine test scenarios included: conventional spark plugs with high energy CDI (

Modern ignition systems may be conveniently divided into TWO types. These are: The first system, having contact breaker points, may be as shown opposite. To improve cold start performance this system may have included into it a The second system may use one of many methods of allowing transistors to switch-off the primary current (this being the ...

The Prediction of Auto Ignition in a Spark-Ignited Engine
SAE Technical Paper Series, 1984<div class="htmlview paragraph">A constant volume combustion simulation has been used to compute the ignition delays of pure fuels and binary fuel mixtures in air. Minima in the ignition delays were predicted by a comprehensive chemical kinetic mechanism for binary fuel mixtures with methane.

Spark ignition engine torque management
Proceedings of the 2003 American Control Conference, 2003., 2004Presented in this paper is a robust feedback controller design procedure to regulate the torque of a spark ignition engine equipped with an electronic throttle mass air flow controller. To this end, a system level model of engine torque production is experimentally determined.

An investigation of the ignition of a gas by an electric spark
British Journal of Applied Physics, 1959By using flashes of microsecond duration it has been possible to obtain a series of shadowgrams showing the development of steadily propagating flames. About 100μs must elapse before any difference can be detected between the flame kernels which will propagate and those which subsequently degenerate.

A new ignition model for spark-ignited engine simulations
Parallel Computing, 2001The amount of spark energy deposited into the combustion chamber is key to an optimum ignition as one can end up with misfires when this energy is low or with other undesired effects on engine performance and byproducts when it is high. Experimentally, up to now, no one has been able to correlate the combustion outcome accurately to the spark ...

Misfire Diagnosis in Spark Ignition Engines
SAE Technical Paper Series, 2002<div class="htmlview paragraph">The paper deals with the implementation of a diagnosis procedure able to reveal if anomalies in the combustion process of a spark ignition engine appear and then to identify the responsible cylinder.</div> <div class="htmlview paragraph">The procedure, based on the processing of the exhaust pressure ...

Minimum ignition energy for laser spark ignition
Proceedings of the Combustion Institute, 2005Abstract Combustion ignition by electrical sparks and nonresonant laser sparks is preceded by breakdown, electron heating, relaxation of internal plasma energy, shock wave generation and propagation, and subsonic flows. Measurements and model calculations of these processes (which occur over times of 10 −12 –10 −1 s) in laser sparks show that the ...
