Prognostics is an engineering discipline focused on predicting the time at which a system or a component will no longer perform its intended function. What is the value of predicting failure? How do you select the right information to create an algorithm? How do you test an algorithm to make sure you are predicting failures properly? This session will explore new algorithms to catch anomalies on various automotive systems. Catching the failure before it happens is the key. Meet the experts.

A new air-cooled SI two-stroke gasoline engine has been developed for an arborist-chainsaw. This engine has a displacement of 25 mm3 and generates about 1.1 kW and complies with the latest CARB and EPA exhaust regulations by optimizing scavenging flows and the use of a catalytic converter. Characteristics of lightweight, compact and high power-to-weight ratio are required for handheld chainsaws, especially for arborist chainsaws. As a matter of course, these characteristics are needed for engine itself in order to satisfy such market requirements for hand-held power equipment. To realize lightweight and compact design, the placement of catalytic converter is optimized for the engine and a two-piece crankshaft is adopted.

The worldwide increasing energy consumption, the decreasing energy resources and the continuous restriction of emission legislation cause a rethinking in the development of internal combustion engines and fuels. Alternative renewable fuels, so called bio-fuels, have the potential to counteract these problems. This study concentrates on the usage of alcohol fuels like Ethanol, Methanol and Butanol in non-automotive high power engines, handheld power tools and garden equipment with the focus on mixture formation and cold start capability. Although bio-fuels have been investigated intensely for the use in automotive applications, the different propulsion systems and operation scenarios of non-automotive applications raise the need for specific research. Therefore, a zero dimensional vaporization model was set up to illustrate the connections between physical properties and mixture formation.
