100% LPG Long Haul Truck Conversion - Economy and Environmental Benefits

2012-09-24
2012-01-1983
Advanced Vehicle Technologies (AVT), a Ballarat Australia based company, has developed the World's first diesel to 100% LPG conversion for heavy haul trucks. There is no diesel required or utilized on the trucks. The engine is converted with minimal changes into a spark ignition engine with equivalent power and torque of the diesel. The patented technology is now deployed in 2 Mercedes Actros trucks. The power output in engine dynamometer testing exceeds that of the diesel (in excess of 370 kW power and 2700 Nm torque). In on-road application the power curve is matched to the diesel specifications to avoid potential downstream power-train stress. Testing at the Department of Transport Energy & Infrastructure, Regency Park, SA have shown the Euro 3 truck converted to LPG is between Euro 4 and Euro 5 NOx levels, CO2 levels 10% better than diesel on DT80 test and about even with diesel on CUEDC tests.

1500 Hp Diesel Electric Tractor

1976-02-01
760647
The experience accumulated with a prototype 1000 HP diesel electric tractor since 1969 is described. The new 1500 HP V220 diesel electric tractors are described along with some of the initial operation of these two units. Experience with the initial 1000 HP unit and the two 1500 HP tractors confirm the necessity of additional testing and experimentation to refine the design to get greater productivity with reduced operator fatigue. The unpredictability of the load and operating surface are major problems that present a real challenge to the engineer.

1983 Ford Ranger Truck HSLA Steel Wheel

1982-02-01

The demand for improved fuel economy in both cars and trucks has emphasized the need for lighter weight components. The application of high strength steel to wheels, both rim and disc, represents a significant opportunity for the automotive industry. This paper discusses the Ranger HSLA wheel program that achieved a 9.7 lbs. per vehicle weight savings relative to a plain carbon steel wheel of the same design. It describes the Ranger wheel specifications, the material selection, the metallurgical considerations of applying HSLA to wheels, and HSLA arc and flash butt welding. The Ranger wheel design and the development of the manufacturing process is discussed, including design modifications to accommodate the lighter gage. The results demonstrate that wheels can be successfully manufactured from low sulfur 60XK HSLA steel in a conventional high volume process (stamped disc and rolled rim) to meet all wheel performance requirements and achieve a significant weight reduction.

1990 Clean Air Act Impacts on Finishing Technology and Operations in the Medium and Heavy Duty Truck & Bus Industry

1995-11-01
952662
The Clean Air Act Amendments of 1990 have brought about wholesale changes in the mandated requirements for the EPA and states to bring clean air to the country. Of particular interest to the light and heavy duty truck and bus industry are the requirements for VOC reductions in Title I, the hazardous pollutant reductions requirements in Title III, and the new permitting scheme required under Title V of the Act. The inter-relationship of lower VOC coatings, hazardous pollutant reduction, and permitting requirements will be presented. Since the Act does not fully mesh these requirements, the pathways that coating suppliers and coating application facilities can use to come into compliance will be explored. Specific VOC content of conforming coatings will be presented, how they will impact application processes, and how hazardous air pollutant reductions can be achieved is explored.

1990-The Engineer and TQM

1990-04-01
900894
This paper will identify the role of the engineer in the Total Quality Management movement. In the latter 1980's quality and reliability were identified as being a result of good business practices, rather than only being effected by manufacturing and design systems. In the past, engineers were given total design responsibility with little or no control once the design left their hands. Product cost analysis recently identified approximately 65% of product cost comes from areas which the engineer cannot control. This paper will show how the skills of the engineer are being integrated into the total business environment through a structured planning system, resulting in products and services with customer focus. Quality and reliability in the 1990's will be a result of this well defined and applied business system.
