Book Development of a Direct injected Natural Gas Engine System for Heavy duty Vehicles

Download or read book Development of a Direct injected Natural Gas Engine System for Heavy duty Vehicles written by and published by . This book was released on 2000 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The transportation sector accounts for approximately 65% of US petroleum consumption. Consumption for light-duty vehicles has stabilized in the last 10--15 years; however, consumption in the heavy-duty sector has continued to increase. For various reasons, the US must reduce its dependence on petroleum. One significant way is to substitute alternative fuels (natural gas, propane, alcohols, and others) in place of petroleum fuels in heavy-duty applications. Most alternative fuels have the additional benefit of reduced exhaust emissions relative to petroleum fuels, thus providing a cleaner environment. The best long-term technology for heavy-duty alternative fuel engines is the 4-stroke cycle, direct injected (DI) engine using a single fuel. This DI, single fuel approach maximizes the substitution of alternative fuel for diesel and retains the thermal efficiency and power density of the diesel engine. This report summarizes the results of the first year (Phase 1) of this contract. Phase 1 focused on developing a 4-stroke cycle, DI single fuel, alternative fuel technology that will duplicate or exceed diesel power density and thermal efficiency, while having exhaust emissions equal to or less than the diesel. Although the work is currently on a 3500 Series DING engine, the work is viewed as a basic technology development that can be applied to any engine. Phase 1 concentrated on DING engine component durability, exhaust emissions, and fuel handling system durability. Task 1 focused on identifying primary areas (e.g., ignition assist and gas injector systems) for future durability testing. In Task 2, eight mode-cycle-averaged NO(subscript x) emissions were reduced from 11.8 gm/hp-hr (baseline conditions) to 2.5 gm/hp-hr (modified conditions) on a 3501 DING engine. In Task 3, a state-of-the-art fuel handling system was identified.

Book Advanced Natural Gas Reciprocating Engine s

Book excerpt: The objective of the Cummins ARES program, in partnership with the US Department of Energy (DOE), is to develop advanced natural gas engine technologies that increase engine system efficiency at lower emissions levels while attaining lower cost of ownership. The goals of the project are to demonstrate engine system achieving 50% Brake Thermal Efficiency (BTE) in three phases, 44%, 47% and 50% (starting baseline efficiency at 36% BTE) and 0.1 g/bhp-hr NOx system out emissions (starting baseline NOx emissions at 2 - 4 g/bhp-hr NOx). Primary path towards above goals include high Brake Mean Effective Pressure (BMEP), improved closed cycle efficiency, increased air handling efficiency and optimized engine subsystems. Cummins has successfully demonstrated each of the phases of this program. All targets have been achieved through application of a combined set of advanced base engine technologies and Waste Heat Recovery from Charge Air and Exhaust streams, optimized and validated on the demonstration engine and other large engines. The following architectures were selected for each Phase: Phase 1: Lean Burn Spark Ignited (SI) Key Technologies: High Efficiency Turbocharging, Higher Efficiency Combustion System. In production on the 60/91L engines. Over 500MW of ARES Phase 1 technology has been sold. Phase 2: Lean Burn Technology with Exhaust Waste Heat Recovery (WHR) System Key Technologies: Advanced Ignition System, Combustion Improvement, Integrated Waste Heat Recovery System. Base engine technologies intended for production within 2 to 3 years Phase 3: Lean Burn Technology with Exhaust and Charge Air Waste Heat Recovery System Key Technologies: Lower Friction, New Cylinder Head Designs, Improved Integrated Waste Heat Recovery System. Intended for production within 5 to 6 years Cummins is committed to the launch of next generation of large advanced NG engines based on ARES technology to be commercialized worldwide.

Book Development of a Direct injected Natural Gas Engine System for Heavy duty Vehicles

Download or read book Development of a Direct injected Natural Gas Engine System for Heavy duty Vehicles written by and published by . This book was released on 2000 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of Phase 2 of this contract. The authors completed four tasks under this phase of the subcontract. (1) They developed a computational fluid dynamics (CFD) model of a 3500 direct injected natural gas (DING) engine gas injection/combustion system and used it to identify DING ignition/combustion system improvements. The results were a 20% improvement in efficiency compared to Phase 1 testing. (2) The authors designed and procured the components for a 3126 DING engine (300 hp) and finished assembling it. During preliminary testing, the engine ran successfully at low loads for approximately 2 hours before injector tip and check failures terminated the test. The problems are solvable; however, this phase of the program was terminated. (3) They developed a Decision & Risk Analysis model to compare DING engine technology with various other engine technologies in a number of commercial applications. The model shows the most likely commercial applications for DING technology and can also be used to identify the sensitivity of variables that impact commercial viability. (4) MVE, Inc., completed a preliminary design concept study that examines the major design issues involved in making a reliable and durable 3,000 psi LNG pump. A primary concern is the life of pump seals and piston rings. Plans for the next phase of this program (Phase 3) have been put on indefinite hold. Caterpillar has decided not to fund further DING work at this time due to limited current market potential for the DING engine. However, based on results from this program, the authors believe that DI natural gas technology is viable for allowing a natural gas-fueled engine to achieve diesel power density and thermal efficiency for both the near and long terms.

Book Effect of Fuel Composition on Regulated Emissions from a Lean burn Closed Loop Controlled Natural Gas Engine at High Altitude

Download or read book Effect of Fuel Composition on Regulated Emissions from a Lean burn Closed Loop Controlled Natural Gas Engine at High Altitude written by Michael S. Graboski and published by . This book was released on 1996 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this test program was to determine the effect of natural gas composition on regulated emissions and performance of a Cummins B5.9G engine. This engine is a lean-burn, closed loop control, spark ignited, dedicated natural gas engine. Testing was conducted at 5,280 ft above sea level. This engine was thought to represent the state-of-the-art in production lean-burn natural gas engine technology at the time the test program was initiated. Five different natural gas fuels were evaluated. Methane content ranged from 76.9 to 90.3% and inerts content from 3.6 to 17.3%. The engine was found to operate well on all gases and net BTU based fuel economy was not effected by gas composition. CO and PM emissions were unaffected by gas composition. NOX emissions were also unaffected. THC emissions trended downwards with increasing fuel heating value but no such trend was observed for NMHC. Emissions from this engine were below all current or proposed standards for heavy duty engines on all fuels tested.
