Conventional Otto, Diesel and Wankel cycle engines even if constructed in advanced light-weight materials cannot meet the required power-to-weight and volume ratios and have high cost. A breakthrough in engine design, operational simplicity and ability to efficiently burn heavy fuels (JP-5, JP-8, DS2) has been demonstrated in a small 2 Hp engine exhibiting 1.1 Hp/lb which has been termed VS-engine. This patented VS-engine when constructed in advanced light-weight materials can be projected to produce power-to-weight ratios in the 1.5 - 2.5 Hp/lb, power-volume ratio approximately 7.5 Hp/in3, power density of 200 - 300 Hp/ft3, and produced at approximately � the cost of an Otto engine. In a joint program with Southwest Research Institute (SwRI), the VS-engine will be modeled utilizing advanced materials to define performance potential, and an engine will be produced in advanced materials and operated with heavy fuels to demonstrate exemplary performance. Benefits: This will provide an engine that can be used for versatile applications such as the aerospace industry for small planes (manned and unmanned) and in the automotive industry for motorcycles, hybrids, cars, buses, and military vehicles.
