It produces aerosol mist of low particle size (below 10 microns) & has fleece media for separation. Aerosol emission of test Engine is reaching till 3.0 gm/hr when operated at rated speed. Particle size measurement using light refraction technique reveals high count of aerosol particles having size below 10 microns. To understand formation of lighter size aerosol mist, turbo charger lubrication is disconnected from engine during measurement. 20 % improvement in aerosol emission observed without turbo charger lubrication. Deflectors are designed in turbo charger oil drain circuit which help the small size oil droplets to coalesce & covert to bigger droplets (above 10 microns) which can be separated more efficiently in the fleece separator. Oil aerosol emission improvement of 20 % observed with introduction of deflectors in turbo charger oil drain circuit. Improvement can be seen across all Engine speed load conditions. Oil aerosol emission optimized without making any change in standard oil separator system.]]> Wed, 07 Feb 2024 11:27:46 GMT https://trid.trb.org/View/2334702 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 Cast Iron Cylinder Blocks: Same Weight as Aluminum; Lower Emissions https://trid.trb.org/View/2155845 Wed, 19 Apr 2023 16:34:20 GMT https://trid.trb.org/View/2155845 On the Potential of Transfer Port Injection Strategies for a Two-Stroke Engine https://trid.trb.org/View/2104331 Mon, 23 Jan 2023 16:23:15 GMT https://trid.trb.org/View/2104331 Experimental Investigation on the Wear and Tear Characteristics of Chrome and Moly Coated Piston Rings Used in Automobile Engine Application https://trid.trb.org/View/2096173 Mon, 09 Jan 2023 16:59:01 GMT https://trid.trb.org/View/2096173 Predictive-Cum-Experimental Analysis of Torsional / Bending and Crankcase Vibrations and Design of Optimum Tuned Damper https://trid.trb.org/View/1799255 Tue, 27 Sep 2022 09:21:06 GMT https://trid.trb.org/View/1799255 Sensitivity Analysis for Structure Borne Noise Reduction of Diesel Engine https://trid.trb.org/View/1795997 Mon, 26 Sep 2022 17:22:21 GMT https://trid.trb.org/View/1795997 Digital AI Based Formulation Development Platform for Crankcase Lubricants https://trid.trb.org/View/2018360 Fri, 23 Sep 2022 17:03:08 GMT https://trid.trb.org/View/2018360 Oil Conditioning as a Means to Minimize Lubricant Ash Requirements and Extend Oil Drain Interval https://trid.trb.org/View/1818814 Mon, 29 Aug 2022 09:27:35 GMT https://trid.trb.org/View/1818814 An Electrical Distribution System for In-Crankcase Applications https://trid.trb.org/View/1820565 Wed, 10 Aug 2022 16:38:44 GMT https://trid.trb.org/View/1820565 Conceptual Design Proposal for Adapting D-Cycle Technology in Agricultural Tractor Engine https://trid.trb.org/View/2004597 Wed, 10 Aug 2022 11:37:27 GMT https://trid.trb.org/View/2004597 Multidimensional CFD Studies of Oil Drawdown in an i-4 Engine https://trid.trb.org/View/2004558 Wed, 10 Aug 2022 11:37:27 GMT https://trid.trb.org/View/2004558 Establishing the Method of Evaluation and Layout Optimization of Crank Case Blow-by Circuit for 3 Cylinder Diesel Engine https://trid.trb.org/View/1822457 Wed, 29 Jun 2022 10:30:28 GMT https://trid.trb.org/View/1822457
