In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems. In this paper, during an engine design and development process, a network analysis of the engine lubrication system is described in detail. Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-d...

− In this two-part paper, a topological analysis of powertrains for refuse-collecting vehicles (RCVs) based on the simulation of different architectures (internal combustion engine, hybrid electric, and hybrid hydraulic) on real routes is proposed. In this first part, a characterization of a standard route is performed, analyzing the average power consumption and the most frequent working point...

In this two-part paper, a topological analysis of powertrains for refuse-collecting vehicles (RCVs) based on simulation of different architectures (internal combustion engine, hybrid electric, and hybrid hydraulic) on real routes is proposed. In this second part, three different hybrid electric powertrain architectures are proposed and modeled. These architectures are based on the use of fuel c...

Abstract Engine mount system affects the automobile NVH performance. Active mounts would achieve excellent vibration isolation and relative displacement control performance in a broad frequency bandwidth by outputting controlled force to mounting system. The actuator method of active determine In this paper, an based on smart material, i.e., Terfenol-D rod, is proposed, which mainly includes th...

A hydraulic engine mount (HEM) is an advanced tuned mass damper (TMD) system used to isolate the noise and vibration from chassis. This paper aims design a semiactive HEM based on TMD model, which only tunes damping without affecting other lumped parameters of system. Firstly, dynamic equations modeled as are derived linear parameter model (LPM). Each analyzed identify relevant that affect damp...

model or time remaining. The planner is designed to be generic to tutors that teach troubleshooting for complex physical devices. It controls the Lower Hoist Tutor, a prototype tutor for the Mark-45 naval gun mount. This tutor teaches troubleshooting of the lower hoist, a complex hydraulic-electronic-mechanical assembly of the Mark-45 The tutor implementation demonstrates the planner’s operatio...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...
