Significant benefits through vehicle and system measures, such as kinetic energy recovery and improved aerodynamics are expected to deliver substantial improvements but the primary The conventional Diesel cycles engine is now approaching the source of loss in the system, the prime mover, is more challenging. practical limits of efficiency. The recuperated split cycle engine is an Reductions in powertrain friction and improvements in combustion alternative cycle with the potential to achieve higher efficiencies than efficiency are likely to deliver brake efficiencies as high as 50% from could be achieved using a conventional engine cycle. In a split cycle conventional compression ignition technologies [1]. The addition of engine, the compression and combustion strokes are performed in waste heat recovery will also drive performance beyond 50%, but there separate chambers. This enables direct cooling of the compression is a broad consensus that brake efficiencies in the range of 50-55% cylinder reducing compression work, intra cycle heat recovery and low represents the technology limit from an advanced compression ignition heat rejection expansion. Previously reported analysis has shown that propulsion system with waste heat recovery. brake efficiencies approaching 60% are attainable, representing a 33% improvement over current advanced heavy duty diesel engine. -

Abstract Heavy and medium duty Diesel engines, for marine and commercial vehicles applications, reject more than 50-60% of the fuel energy in the form of heat, which does not contribute in terms of useful propulsion effect. Moreover, the increased attention towards the reduction of polluting emissions and fuel consumption is pushing engine manufacturers and fleet owners in the direction of increasing the overall powertrain efficiency, still considering acceptable investment and operational costs. -

Service Contract (Lecom029)
SERVICE CONTRACT (LECOM029) APPENDIX A TO STATEMENT OF WORK (SOW) DES LE PfMO PEng Eng - Technical Publications Portfolio Review As At 11 June 2014 11 June 2014 DES LE PfMO PEng Eng - Technical Publications Portfolio Review Summary This review covers 96 publications from the DES LE PEng Eng Technical Publications Portfolio. All of the standards were reviewed by experts in the various fields covered across the 96 documents. The documents’ content, spelling & grammar as well as the currency of any other standards, organisations or materiel referred to, were all taken into account during the reviews. In a few cases, the need for the document at all was questioned, these were: • AESP 0200-A-201-013 – Welding Cutting and Brazing • AESP 0200-A-207-013 – Wet Abrasive Cleaning Process • AESP 0200-A-210-013 – Repair of Threaded Holes by Insert • AESP 0200-A-232-013 – Timber Selection, Preservation and Finishing • AESP 0200-A-237-013 – Fibre Optic Technology • AESP 2610-A-409-8 Pneumatic Tyres and Tubes Associated Road Wheels • Def Stan 34-1 – Flux, Soldering (Zinc Chloride Solution) • Def Stan 68-199 – Windscreen Wash Liquid Concentrate It is recommended that the usage and necessity for these documents is investigated Additionally, it is noted that all Def Stans feature the following preliminary paragraph: “3.3 In consideration of clause 3.2 above, users shall be fully aware of the issue and amendment status of all normative references, particularly when forming part of an Invitation to Tender or contract. Responsibility for the correct application of standards rests with users.” This could be overcome by not making specific reference to issue levels and years of release in the main body of the document. -
