10/4/99 - Virtual 4-Stroke®: Design and Simulation of Four-Stroke Engines PITTSBURGH, PA, October 4, 1999 - OPTIMUM Power Technology has finalized an agreement with the Society of Automotive Engineers (SAE) to promote and sub-license OPTIMUM’s four-stroke engine simulation software product, Virtual 4-Stroke Design and Simulation of Four-Stroke Engines (CD-ROM) This software is sold through SAE as SAE Order No. R-186M. The Virtual 4-Stroke SAE Edition engine design and simulation software consists of four main components: Design, Simulation Explorer, Analyze and Dynoscope. Design is a preprocessor interface for the engine simulation software. Simulation Explorer is an integrated database for storage of input and output data. Analyze allows the user to access the results for tests that have been simulated and produce graphical output in terms of standard performance measurements. Dynoscope allows the user to produce transducer output graphs from throughout the engine. This engine simulation model will simulate a single-cylinder naturally-aspirated four-stroke engine with the following attributes: almost any two-valve or four-valve cylinder head; variable intake ducting geometry and simple silencer; and variable exhaust ducting geometry and simple silencer. This software product is sold in conjunction with Professor Gordon P. Blair’s book Design and Simulation of Four-Stroke Engines. (SAE reference R-186) Users must have Microsoft® Excel available on their computer to observe the graphic output data from the simulation. OPTIMUM Power Technology applies computer technology to two and four-stroke engines. Research at OPTIMUM focuses on enhancing the performance of and reducing emissions from these engines. OPTIMUM’s products span from engine simulation software to vehicle data acquisition. Products are available for pressure trace analysis, engine management systems, fuel injection, and dynamic testing. OPTIMUM Power Technology is located in Bridgeville, Pennsylvania.
