integration possibilities in industry fabrication standards
reduced emissions

The above fuel economy benefits are based on two independent engine friction models extensively used in the industry. While piston friction accounts for more than 1% of total energy consumption in the US, the RLE is expected to reduce piston mechanical losses
by 50-70%. Based on the preliminary prototype results, these estimates are confirmed.
