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 Multi-objective Optimization of Injection Molding Process Based on One-Dimensional Convolutional Neural Network and the Non-dominated Sorting Genetic Algorithm II https://trid.trb.org/View/2341853 Tue, 20 Feb 2024 10:04:54 GMT https://trid.trb.org/View/2341853 Riverbank Stabilization Using Low Cost Submersible Pumps https://trid.trb.org/View/2270561 Fri, 16 Feb 2024 15:30:59 GMT https://trid.trb.org/View/2270561 Weight and Drivetrain Optimization via Fuel Pump & Vacuum Pump Drive Integration on Engine Camshaft in a Pushrod Type Valve Actuated Engine https://trid.trb.org/View/2334753 Wed, 07 Feb 2024 11:27:47 GMT https://trid.trb.org/View/2334753 Experimental investigation on dehumidification and heating performance of a heat pump system concerning dew or fog removal for electric vehicles https://trid.trb.org/View/2325670 Mon, 29 Jan 2024 09:18:34 GMT https://trid.trb.org/View/2325670 DRBFM Methodology Applied to Design Changing in Fuel Supply Modules https://trid.trb.org/View/2325814 Mon, 22 Jan 2024 15:31:33 GMT https://trid.trb.org/View/2325814 Validation of Methods for Rapid Design and Performance Prediction of Water Pumps https://trid.trb.org/View/1790741 Wed, 20 Dec 2023 16:58:04 GMT https://trid.trb.org/View/1790741 Power Steering Pump with Enhanced Cold Start Priming https://trid.trb.org/View/1790519 Tue, 19 Dec 2023 17:03:48 GMT https://trid.trb.org/View/1790519 Semi-autonomous operation of a mobile concrete pump https://trid.trb.org/View/2253944 Tue, 28 Nov 2023 10:37:41 GMT https://trid.trb.org/View/2253944 Analysis of Rotor Dynamics Characteristics of Roots Hydrogen Circulation Pump https://trid.trb.org/View/2289527 Sat, 25 Nov 2023 17:29:21 GMT https://trid.trb.org/View/2289527 The Effect Of Biopolymer Treatment On The Potential Instability Of A Soft Soil Under Cyclic Loading https://trid.trb.org/View/2239154 Thu, 05 Oct 2023 09:32:28 GMT https://trid.trb.org/View/2239154
