This work is a continuation of previous durability studies that identified three key technical risks after running gasoline-like fuel through a heavy-duty, common rail injection system: (i) cavitation damage to the inlet check valve of the high-pressure pump, (ii) loss of injector fueling capacity, (iii) cavitation erosion of the injector nozzle holes. Upgraded hardware solutions were tested on a consistent 400- to 800-hour NATO durability cycle with the same gasoline-like fuel as previous studies. The upgraded pump showed no signs of abnormal wear or cavitation damage to the inlet check valve. In contrast to previous studies, there were no signs of pump performance degradation observed after 400 hours of testing. Material selection and design upgrades were also made to the injector which, only showed a 6.5% loss in fueling capacity after 800 hours of durability testing compared to 49.3% previously. Finally, geometric nozzle hole features such as higher inlet radius of curvature and higher K-factor were found to correlate with reduced cavitation erosion. However, mitigation of eccentric radial needle motion (i.e., wobble) is likely needed to further suppress cavitation. In general, the results from this study indicate there are viable hardware-based solutions for improving the endurance of high-pressure systems when running with gasoline-like fuel.]]> Tue, 20 Feb 2024 10:05:40 GMT https://trid.trb.org/View/2341900 Development of New Generation Low Ash Type Diesel Engine Oils for Heavy Duty Vehicles https://trid.trb.org/View/1782313 Wed, 07 Feb 2024 16:52:59 GMT https://trid.trb.org/View/1782313 Investigation of the Helical Inlet Port https://trid.trb.org/View/1782166 Wed, 07 Feb 2024 16:52:59 GMT https://trid.trb.org/View/1782166 Anisotropic structural modeling of fiber-reinforced polymers used in engine peripheral components https://trid.trb.org/View/2325826 Mon, 22 Jan 2024 15:31:33 GMT https://trid.trb.org/View/2325826 Influence of valve spool shoulder wall angle on steady-state hydraulic force https://trid.trb.org/View/2289225 Fri, 22 Dec 2023 08:46:59 GMT https://trid.trb.org/View/2289225 A Knowledge-Based Model for Multi-Valve Diesel Engine Inlet Port Design https://trid.trb.org/View/1794089 Mon, 04 Dec 2023 12:27:08 GMT https://trid.trb.org/View/1794089 API CI-4: The First Oil Category for Diesel Engines Using Cooled Exhaust Gas Recirculation https://trid.trb.org/View/1794076 Mon, 04 Dec 2023 12:27:08 GMT https://trid.trb.org/View/1794076 Study the Effect of Pneumatic Valve Characteristics due to Linear and Non-Linear Damping System https://trid.trb.org/View/2296615 Tue, 28 Nov 2023 11:32:58 GMT https://trid.trb.org/View/2296615 Experimental Comparison of a Rotary Valvetrain on the Performance and Emissions of a Light Duty Spark Ignition Engine https://trid.trb.org/View/2289560 Mon, 13 Nov 2023 16:14:18 GMT https://trid.trb.org/View/2289560 Performance Prediction of an e-Compressor Using 3D CFD Simulation https://trid.trb.org/View/2259898 Tue, 03 Oct 2023 15:41:48 GMT https://trid.trb.org/View/2259898 High Performance and Near Zero Emissions 2-Stroke H2 Engine https://trid.trb.org/View/2250349 Tue, 19 Sep 2023 16:20:21 GMT https://trid.trb.org/View/2250349 Preliminary experiences in the design of an electromechanical valve actuator https://trid.trb.org/View/1791898 Mon, 28 Aug 2023 09:29:04 GMT https://trid.trb.org/View/1791898
