This practice describes recommended performance requirements of fuel tank closures used in conjunction with fuel level senders and fuel delivery systems. It provides guidelines that assure interchangeability and compatibility between fuel tanks and fuel pump/sender closure systems without specifying a specific closure system design. These systems may be used in rigid fuel tank systems made of plastic or metal. Complete details of specific designs shall be established by mutual agreement between customer and supplier. The dimensions and performance requirements are selected to optimize a The closure system, durability and reliability with respect to — Vehicle SHED measurements — Fuel system / crash integrity — LEV – II useful life b Assembly and service ease and reliability c Packaging of fuel tanks and their sending units d Interchangeability of sender closures between various fuel tank designs

Compressible Brake Fluid Turbulent Flow Simulation and Experimental Verification on Brake Bleeding Performance Improvements of an EPB Caliper

Mando-Jang-Oh Mo
Published 2018-10-05 by SAE International in United States
Brake bleeding is the process of removing air bubbles present on hydraulic brake systems from the master cylinder to the calipers of a vehicle, including the brake pipes and hoses. This is very important procedure affecting on brake performance, but still has been a key issue in automobile industry for last decades because reaching best bleeding performance has a limit that there is always remaining air in brake system. In this paper, it is reported on numerical and experimental investigations into the topic of bleeding performance improvements. Compressible brake fluid turbulent flow simulation with two-phase mixture model was performed to investigate the details of the bleeding performance drop during its cycles. The rig test of the hollow cylinder was carried out in order to secure the brake consumption amount curve whose results were used for the criterion of the parametric simulations using Tait equation to estimate the property of the brake fluid with the bulk modulus of 19,535 bar and 0.00016%. It was observed that the experimental curve data from the rig test of the…

Direct Injection Gasoline Fuel Injector Characterization

Gasoline Fuel Injection Standards Committee
  • Ground Vehicle Standard
  • J2713_201808
  • Current
Published 2018-08-28 by SAE International in United States
This SAE Recommended Practice promotes uniformity in the evaluation and qualification tests conducted on GDI fuel injectors used in gasoline engine applications, where fuel pressures are typically well above 1 MPa. The document scope is limited to electrically-actuated fuel injection devices used in automotive GDI systems and is primarily restricted to bench tests.

Motor Vehicle Brake Fluid Container Compatibility

Brake Fluids Standards Committee
  • Ground Vehicle Standard
  • J75_201807
  • Current
Published 2018-07-12 by SAE International in United States
Motor vehicle brake fluid must conform to the requirements of SAE J1703 or J1704, not only when manufactured, but also after extended storage in any commercial packaging container. The purpose of this SAE Information Report is to generate an awareness of the major problems involved in the storage of brake fluids and, to some extent, provide means of circumventing them. It is also the purpose of this document to relate to experience and to test data accumulated and to list certain conclusions which should aid in the proper selection of containers for brake fluid.

Speed Tracking Control for All-Terrain Vehicle Considering Road Slope and Saturation Constraint of Actuator

Tongji University-Manfei Bai, Lu Xiong, Zhiqiang Fu, Renxie Zhang
Published 2017-09-23 by SAE International in United States
In this paper, a speed tracking controller is designed for the All-terrain vehicles. The method of feedforward with state variable feedback based on conditional integrators is adopted by the proposed control algorithm. The feedforward is designed considering the influence of the road slope on the longitudinal dynamics, which makes the All-terrain vehicles satisfy the acceleration demand of the upper controller when it tracks the desired speed on the road with slope varying greatly. The road slope is estimated based on a combined kinematic and dynamic model. This method solves the problem that road slope estimation requires an accurate vehicle dynamic model and are susceptible to acceleration sensor bias. Based on the vehicle dynamic model and the nonlinear tire model, the method of conditional integration is used in the state variable feedback, which considers the saturation constraint of the actuator with the intention of preventing the divergent integral operation. The control algorithm proposed in this paper can meet the requirements of vehicle speed tracking by controlling the engine driving torque and EHB brake fluid pressure. In…

Brake Hydraulic Component Flow Rate Measurement for High Differential Pressure (>5 bar)

Hydraulic Brake Components Standards Committee
  • Ground Vehicle Standard
  • J3052_201705
  • Current
Published 2017-05-18 by SAE International in United States
This recommended practice provides a method, test set-up, and test conditions for brake hydraulic component flow rate measurement for high differential pressure (>5 bar) flow conditions. It is intended for hydraulic brake components which affect the brake fluid flow characteristics in a hydraulic brake circuit, that are part of a circuit for which the flow characteristics are important to system operation, and that are exposed to high operating pressure differentials (in the 5 to 100 bar range). Typical applications may include measurement of flow through chassis controls valve bodies, orifices in the brake system such as in flow bolts, junction blocks, and master cylinders, and through brake pipe configurations.

Comprehensive Diagnostic Methodology

Ford Motor Company-Gopal K. Chamarthi, Andrew Sarkar, Paul Baltusis, Mark Laleman
Published 2017-03-28 by SAE International in United States
An average luxury car contains more than 50 sensors connected, to over 28 microprocessors, through multiple communication networks. What makes these complex machines diagnosable at a dealership, is the ability of sophisticated diagnostics algorithms. Besides use of diagnostics in service, diagnosing a failure is also key for functional safety and vehicle availability. Safety related diagnostic functions such as loss of Brake fluid and leaky fuel system detection are critical. Once a failure is detected, Vehicle availability functions extend vehicle operation, so that one could reach the dealership without being stranded. The number of failure modes in a car could far exceed tens of thousands, thereby identifying key failure modes that require diagnostics can be a challenge. Although regulations have done a great job of enforcing key diagnostic requirements through law, it is still essential to understand the science behind diagnostics development to provide high level of serviceability, Safety and Customer experience. This paper shares an approach for Comprehensive Diagnostics Methodology based on Sub-System Functional Failure Modes and Effects Analysis (FMEA), which is different than conventional…
