The engine mount transmission force can be used as an important basis to evaluate the vibration isolation performance of mounting system. However, there is a lack testing equipment and methods for force. sensor test method studied. finite element model established analyze arrangement position sensor. developed based on resistance strain gauge. arranged in middle intermediate bolt. system at sam...

Mechanical vibrations have a significant impact on ride comfort; the driver is constantly distracted as result. Volumetric engine inertial unbalances and road profile irregularities create mechanical vibrations. The purpose of this study to employ optimization algorithms identify structural elements that contribute vibration propagation provide optimal solutions for reducing induced by unbalanc...

Cam phasing, or Variable Valve Timing (VVT), is an electro hydraulic and mechanical camshaft control concept managed by the vehicle's microcontroller engine management system. Development and implementation of cam phasing mechanisms is pursued by the automotive industry today because it gives measurable increase in performance, and reduction in undesired engine emissions. This paper illustrates...

Hydraulic hybrid propulsion and energy storage components demonstrate characteristics that are very different from their electric counterparts, thus requiring unique control strategies. This paper presents a methodology for developing a power management strategy tailored specifically to a parallel Hydraulic Hybrid Vehicle (HHV) configured for a medium-size delivery truck. The Hydraulic Hybrid V...

Recently, the high-pressure fuel injection performance of common-rail direct injection (CRDi) engines has become more important, due to the need to improve the multi-injection strategy. A multiple injection strategy provides better emission and fuel economy characteristics than a normal single injection scheme. The CRDi engine performance changes with the type of high-pressure electro-mechanica...

Do leaks of hydraulic fluids and jet engine lubricating oils cause potentially toxic fumes to be released into the cabins of commercial airliners? If so, do those fumes cause acute and chronic health problems such as headache, nausea, fatigue, memory loss, and neuromuscular damage in airline crew members and passengers? Those simple questions are at the heart of a brewing controversy. Advocacy ...
