用壳牌合成润滑油进行广泛的本地研究，提供了强大的燃油经济性效益

随着运营成本的增加，运输业不断追求效率。对于所有尺寸的卡车队列，主要成本投入是燃料和润滑剂，以保持它们移动。在澳大利亚运输业，Viva Energy，这一国家的壳牌产品的驾驶能源中占领职位，设定了进行广泛的研究，以确定是否存在直接的燃油雷电竞经济性益处，从使用合成润滑油。

在使用壳合成润滑剂产品时，结果尚未起诉，并指出潜在的燃油经济性较高且较高2.5％。壳牌合成润滑剂不仅提供了提供潜在的燃油效率改进的机会，而且提供更好的组件保护和可靠性超过更长的排水区间。

虽然多年来，虽然多年来，较多的研究效率，大多数情况下，如果并非所有人在欧洲或美国进行，并且与在澳大利亚的日常运输公司的情况有限。

雷电竞Viva Energy Chent几个月建立可信的研究模式，以测试壳牌矿物和合成运输动机润滑油系列，并专注于与澳大利亚的运输公司所有者和决策者相关的内容。

The theory behind the research brief was straight forward, but had some challenges in the application. To perform a series of chassis dynamometer tests on a heavy duty truck to determine whether a fuel consumption benefit can be derived from the replacement of mineral based engine, transmission and axle oils with synthetic alternatives.

“Our Shell Lubricants team devised a wide ranging research study that was totally focused on Australian driving conditions. We took the step to commission the work after highly credible partners were identified to independently oversee the research. As the licensee of Shell products in Australia, the importance of rigorously testing the full range of Transport Lubricants was an important step to allow us to further understand the performance of the Shell Synthetic Lubricants range across a broad range of conditions,” said Paul Smallacombe, Viva Energy’s Product Support Engineer.

Viva Energy worked with Industry specialists who have the track record and equipment in identifying potential fuel efficiency gains. First up, Melbourne based Kangan Institute Automotive Centre of Excellence was engaged to supply the chassis dynamometer together with expertise on the operation of the sophisticated dyno. The transient drive cycle selected provided a representative mix of Australian congested city, urban fringe and highway driving.

Secondly, it was decided that the test should be conducted by a specialist transport research company and ABMARC was chosen. ABMARC is an independent Australian company with a team of highly experienced engineers and research staff who deliver a broad range of services to the transport and energy sectors. ABMARC are specialists in precisely measuring fuel efficiency improvements and have a long history of similar projects in the industry.

“雷电竞Viva能源接近ABMARC，简要了解合成润滑剂的真实世界表现，作为与传统矿产润滑油相比减少燃料消耗的贡献者，”Abmarc环境和技术服务经理James Payne解释说。“该研究的设计模拟了重型车辆的真实世界条件，但在受控实验室环境中。我们使用的燃料测量技术是澳大利亚唯一的类型，提供最精确的测量。我们的测试方法提供了出色的重复性和统计学意义，使Viva能量对结果提供了高度信心。“雷电竞

Rather than utilising a brand new low km vehicle, Viva Energy decided to use a representative on highway configuration truck for the testing. A Western Star 5800SS with a Detroit Diesel 14.8L engine with 370,000km on the clock was chosen and the various parties then established the clear parameters for the testing to commence.

一个综合测试程序，由多个驱动循环重复组成，发动机变暖是整体策略。测试中使用的驱动周期是澳大利亚的驱动周期，反映了典型卡车操作员在澳大利亚的道路上经历的驾驶条件。它包括一系列地铁停车，外城和公路跑，以反映实际的道路状况。

The impact of changing the lubricants was assessed based on fuel consumption in transient conditions, simulating driving the heavy duty on-highway truck in an Australian environment.

The fuel measurement system was connected to the three fuel lines:

• Fuel flow from tank (at the exit of the pre-filter)
• 燃料流向发动机（在进入主滤波器时）
• Fuel return from engine (at the tee, leading to the LHS/RHS tanks)

This allowed the net fuel consumption to be measured with a single fuel flow meter, improving test measurement accuracy and repeatability.

为了模拟牵引拖车的测试车辆并提供现实世界中的燃料消耗最逼真的迹象，可以通过测功机中的最小化轮胎滑动在滚筒上的最大惯性。模拟车辆惯性为25,000千克。这代表了通过测试模拟的总车辆质量。

对测试制度结果至关重要的是使用的壳牌运输润滑剂。用矿物油进行测试循环，然后用合成液重复。

Summary of Oils Tested

All lubricants were filled to the dipstick maximum in the case of the engine oil and filled to level via the transmission and axle fill points.

尽管矿物和合成润滑油both approved for use by the engine manufacturer, to limit the effect of carry-over from previous oils used in the Western Star truck, a process was devised for oil changes to remove any chance of cross contamination of the lubricant products as follows:

• Drain previous oils
• Fill to level with fresh oils, replacing engine and transmission oil filters
• Vehicle warm up and flush by driving transient cycle
• Drain oil
• Final fill with fresh oils, replacing engine and transmission oil filters

The first round of tests was conducted with Shell mineral oils then substituted with Shell Synthetic oils. All testing was conducted to the same parameters and conditions by ABMARC at the Kangan Institute Automotive Centre of Excellence.

Sixteen tests (8 mineral, 8 synthetic) were used as the basis for the research conclusions. Based on the drive cycle tests, there was on average a 2.5% reduction in fuel consumption using the Shell Synthetic Technology Oils in the Western Star test vehicle compared to using the mineral based oils. ABMARC’s report confirmed with 95% confidence that this fuel consumption reduction can be attributed to replacing the mineral engine, transmission and rear axle oils with the Shell Synthetic Technology Oils.

The series of testing and monitoring on the chassis dynamometer coupled with the highly sophisticated fuel measurement system utilised for this study has provided new data that is a potential first in testing on Australian driving cycles.

“The fuel consumption saving results achieved in the testing were impressive. The Shell Synthetic Lubricants range of products performed faultlessly throughout the testing regime and this research has the potential to offer real substantive benefits to the Australian transport industry,” concluded Paul Smallacombe. “A 2.5% reduction in one of the largest cost components for transport operators is significant.”
