Sažetak
Future engine designs will be more fuel efficient and environmentally friendly. These are being driven by government regulations and mandates as well as consumer demand. The International Lubricant Standardization and Approval Committee (ILSAC), which is comprised of the North America Engine Manufacturer’s Association (EMA) as well as the Japanese Automobile Manufacturer’s Association (JAMA), was formed to develop minimum performance standards for lubricants which enable vehicle and engine manufacturers to increase fuel economy, reduce emissions, and improve durability and reliability of their vehicles and engines.
The current performance category of ILSAC oil, GF-4, was introduced in July 2004. Work on the next generation oil, GF-5, began in 2005 and is scheduled to be completed in time for a commercial introduction of GF-5 oil during the 4th quarter of 2010 in time for 2011 model year vehicles. Relative to GF-4, there are three primary performance areas of GF-5 that have been identified for improvement: (1) Fuel economy and fuel economy durability, (2) Emissions system compatibility, and (3) Overall oil robustness. The desire for fuel economy improvements are being driven in part by U.S. government regulations requiring Corporate Average Fuel Economy (CAFÉ) to reach 35 miles per gallon by 2020. The current CAFÉ requirement is 27.5 miles per gallon. In addition to government mandates, record fuel prices have driven consumer demand and focus towards improved fuel economy. The ILSAC GF-5 category will include a new lab engine test which will assess the ability of engine oils with respect to fuel economy performance. In order to assure emissions compliance during the life of the vehicle, the Environmental Protection Agency (EPA) has established a 10 year/120,000 mile (194,000 km) useful life in which the vehicle must remain within certain emissions limits. In addition, the mandated use of On-Board Diagnostic (OBD) systems assure the vehicles do not exceed certain limits and continue to operate properly during their useful life. A certain amount of engine oil is burned in engines and ash forming compounds can lead to fouling of exhaust emissions systems. Therefore, besides protecting the engine from wear, compatibility of engine oil with exhaust emissions systems is an important performance parameter. The ILSAC GF-5 category will include a test and chemical limits that help assure improved emissions system compatibility.
Improvements in vehicle and engine design, as well as increased purchase costs, have resulted in customers extending trade-in cycles and, as a result, the average vehicle age has increased in many markets. Oil robustness plays a major role in extended engine life. The ILSAC GF-5 category will include engine tests and performance targets to assure proper engine oil robustness to allow extended engine durability. In this presentation, we will provide an overview of the drivers for the ILSAC GF-5 engine oil category and also discuss the performance tests and li-mits that are being established to assure the category meets the industry objectives.
