Potential of use of neat renewable hydrotreated vegetable oil fuel in agricultural machinery: Performance and regulated emissions under quasi steady and transient load increase

The performance and regulated emissions from a Stage V tractor engine using a neat hydrotreated vegetable oil (HVO) and a typical agricultural diesel fuel were evaluated. Tests were carried under different quasi-steady state modes and with a continuous load variation test reaching maximum torque (fu...
