SAE Truck & Off-Highway Engineering: December 201919TOFHP1212/05/2019
Heavy-duty engine design What are the most significant factors influencing the way engine developers approach near-term design and development cycles? Two experts provide their insights from recent programs. Reducing winter range loss for electric trucks Researchers at the Austrian Institute of Technology have developed an air exchange system that's capable of reducing heat load by 37% in real-world tests. Narrower focus, bigger payoff Design teams are targeting focused markets for their commercial electric-vehicle programs to combat challenges like range and infrastructure. Removing complexity for autonomous trucks Narrowing the operating domains for driverless commercial vehicles reduces the requirements of autonomous technology and speeds time to market.

Statistical Experimentation of Fuel System O-Ring Interface2011-01-051404/12/2011
O-rings are regularly utilized as a means of creating a seal between two components. Since the introduction of mini-concentric fuel pressure regulators, several issues have arisen related to assembly. In many cases, severe leaks are masked by lubricants used to aid in assembly. A lubricant is required which will not mask such leaks. The purpose of this study is to determine the impact on assembly between alcohol and oil based lubricants and to determine the optimum assembly parameters when using alcohol lubricants. Several variables were identified as being major contributors to the assembly process. A total of 6 variables were chosen to be examined as well as 2 noise factors. Each variable, or factor, was assigned several levels for this experiment. Several measurables were defined outputs from the experiment. To maximize the efficiency of testing, an orthogonal array was used to structure the experiment. An L18 orthogonal array was chosen composed of 72 trials. When conducting a

Development of Leak Tightness Specifications for Automotive Fuel System Components as Required to meet Hydrocarbon Emission Regulations using the Equivalent Channel Concept and its Implementation Method for Production Leak Testing2010-01-110404/12/2010
Determination of appropriate leak tightness specifications for production leak testing of fuel system components has challenged the automotive industry for many years. This process has become more complicated as hydrocarbon emission regulations have been lowered (US-EPA, CARB LEVII, Euro5, etc.). Application of the equivalent channel (EC) concept can significantly simplify the process of determining leak tightness specifications. This paper describes the test procedure and results of a hydrocarbon emission study designed to define a critical geometry (known as Equivalent Channel-EC) that will plug after exposure to gasoline, resulting in no HC emission due to leaks during Vehicle SHED (Sealed Housing for Evaporative Determination) tests. This critical geometry will stop any measurable hydrocarbon leakage after enough time has elapsed for the channel to plug. Micro-channels of several diameters and lengths were tested in a Micro-SHED at 40 degrees Celsius for 24 hours. SHED tests were

Ultrasound Techniques for Leak Detection2009-01-215905/19/2009
Leak detection of vehicle cabin interiors is an important quality inspection phase that typically has been handled with various time consuming, or potentially product damaging techniques. Leak detection in tank or pressure vessel applications is almost always a concern for gas or fluid containment in vehicles and in many other industries. Numerous techniques exist for the detection of leaks in these and other types of structures. When testing is required in a production environment, often the speed of leak detection is very important if all samples must be tested. The use of several ultrasound based methods for leak detection in vehicle cabins and pressure vessel applications is presented here. Ultrasound waves are typically classified as having spectral content greater than 20 kHz. In the case of leak detection in a production environment, frequently the ultrasonic spectrum is largely free from background noise content that dominates the audible spectrum. The method for the response

Gas-Based Production Leak Testing Techniques For Automotive Components2006-01-140804/03/2006
This paper outlines the methodology to 1) determine what leak rate specification is appropriate for a given automotive component, 2) arrive at the gas-based leak test method that is best suited for the situation, and 3) perform the requisite calculations to confirm the choice of test method. Also provided are summary tables (based upon actual industry experience) relating component type, typical leak rate specification, test method used, and (production) sensitivity range of the method utilized.
