Managing engine oil temperatures and extending service intervals has caused many engine designers to consider crankshaft windage trays. With benefits such as reducing oil aeration and oil temperature while improving engine performance, windage trays have long been used in performance engines. Most automotive engines would benefit from the introduction of windage trays. This paper outlines a new approach in the form of an oil management module for the lower engine, a one piece glass-reinforced nylon composite system which integrates a windage tray with other oil system components such as: pan gasket, pick-up/strainer, baffling and sensor interface. The oil management module is very near to reality since it is the integration of proven nylon composite applications and not a totally new application.

A new design of an air induction system for a Four-cylinder automobile engine is described. The principle function of the system is the reduction of air induction noise. The potential and theory for improved engine performance is discussed. The system incorporates multiple side branch resonators tuned to the frequency of the fundamental air induction tone over the critical operating range of the engine, typically 2000 to 5000 rpm. The resonators are packaged in unique ways permitting a variety of configurations which can conform to available “low priority” space under the hood. The flexibility of this system allows it to be integrated into the hood or secondary dash, for example. Rules governing design are given. Packaging concepts are offered. Manufacturing and assembly considerations are discussed.
