Abstract:

In order to develop more efficient engines, it is essential to optimize the lubrication circuit of the power train systems.

Two elements have been added to the lubrication circuit in the modified engine. These elements are hydraulic lifters and an Anti-drain valve.

The analyses are done by Flowmaster7.6 and AVL EXCITE7.02 software and an accessory code.

 Finally, theoretical results are validated by a completely controlled lubrication functional test.

 Keywords:

Lubrication Circuit

Bearing Map

Chain Tensioner

Flowmaster

Journal Bearings

Introduction:

Modern engines are being designed to operate at high engine speeds and loads. In order to fulfill the requirements of developing new engines, lubrication system must be improved.

üYiqing Yuan et al, in 2007, established a methodology for predicting lubrication flow in the rod bearings and oil circuits that can be used to guide engineering designs.

üYaguo Lu et al. [10], in 2009, developed a software for simulating aero-engine lubrication system.

In this paper, two important components, chain tensioner and anti-drain valve, have been investigated as well as other components in the lubrication system.

Engine description:

There are three important reasons for improving the base engine to the modified engine:

 (1) using inexpensive and locally abundant CNG fuel,

 (2) demanding higher power and

 (3) modifying weaknesses of the base engine. The engine parameters are listed in table.

A Survey on Wireless Sensor Network Clustering Protocols Optimized via Game Theory

اختصاصی از فی بوو A Survey on Wireless Sensor Network Clustering Protocols Optimized via Game Theory دانلود با لینک مستقیم و پر سرعت .

ABSTRACT
Wireless sensor network (WSN) consists of low size, power
constrained nodes that sense the environment and communicate
this information through wireless links. There are a number of
research issues in WSN with energy efficiency being one of the
prime issues for WSN applications. In clustering-based routing
protocols, cluster head selection has significant effect on
performance of the protocol, along with routing technique. Game
theory as a mathematical notion, being able to analyze interactive
decision situations, is applicable to a wide spectrum within WSN.
It can assist in designing more efficient protocols. This article
surveys the application of game theory in wireless sensor network
protocols, specifically in the domain of communication protocols
involving cluster formation i.e. clustering protocols in WSN and
how it optimizes the functioning of these protocols.
