Melbourne Automobile Emissions Study
The University of Denver's remote sensor (FEAT) was used for an on-road motor vehicle carbon monoxide (CO) and hydrocarbon (HC) emissions survey in Australia during April and May, 1992. Twelve locations in Melbourne area were selected as the survey sites. Most of these locations were the on or off ramp of a freeway or a two way road divided by a solid or painted traffic island. The raw data fro...
متن کاملCombustion Improvement for Reducing Exhaust Emissions in DI Diesel Engine
Multidimensional modelling of open-cycle process of OM355 engine was developed. Calculations for computational mesh were carried out. The results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. Results included pressure, temperature, emission and Rate of heat rel...
متن کاملIntegrated Inspection Planning and Preventive Maintenance for a Markov Deteriorating System Under Scenario-based Demand Uncertainty
In this paper, a single-product, single-machine system under Markovian deterioration of machine condition and demand uncertainty is studied. The objective is to find the optimal intervals for inspection and preventive maintenance activities in a condition-based maintenance planning with discrete monitoring framework. At first, a stochastic dynamic programming model whose state variable is the ...
متن کاملAutomated CAD-Guided Automobile Part Dimensional Inspection
Structured light is one of the well-known methods in part dimensional inspection that have been successfully employed in various applications in the past decades. In this method, the positioning of the camera is very critical, which a ects the accuracy and e ciency of the whole inspection system. Here we develop a CADguided camera positioning system to aid the 3-D part inspection. The geometric...
متن کاملVisualizing sphere-contacting areas on automobile parts for ECE inspection
To satisfy safety regulations of Economic Commission for Europe (ECE), the surface regions of automobile parts must have a sufficient degree of roundness if there is any chance that they could contact a sphere of 50.0 mm radius (exterior parts) or 82.5 mm radius (interior parts). In this paper, a new offset-based method is developed to automatically detect the possible sphere-contacting shape o...
