Began preliminary testing on RLE and baseline engine to determine friction reduction estimates and face seal reliability
2021
Preliminary testing confirmed face seal reliability under high pressure and fuel consumption benefits of up to 40% at idle conditions
2022
Testing under approximately 30% load proved fuel economy benefit of 12% - 14%
2023
Interest expressed by a major Tier I manufacturer, Mahle Current - Validating fuel economy benefits at higher loads
