Many challenging issues also arise when considering wind energy. The biggest issue, some say, is that wind energy is not reliable, dependable, or consistent enough to be taken seriously; any more than on small scale applications. Due to the inconsistent nature of wind, it cannot be a contributor for base load energy production. The industry has, and is currently addressing this issue of “intermittent” power generation from wind by means of energy storage. That is to say, produce the energy when the opportunity arises and store the energy for later use when demand levels increase. Energy storage technology has been continuously being developed for various types of renewable energy. The two primary energy platforms this applies to is wind and solar. Wind doesn't blow 24/7 nor does the sun always shine. In order to overcome these drawbacks, the following modifications requires in our traditional wind mill structure. a. By fixing solar strip over turbine blades, we could generate electricity when the wind turbine slows or stop. b. By placing hydrogen storage compartment in a turbine tower, the plant could produce hydrogen through an electrolyser when there is excess wind energy available, and then provide electricity to domestic customers via a fuel cell and a hydrogen combustion engine. The proposed solution will be especially useful in areas with insufficient power production or insufficient electricity infrastructure. For instance, stored hydrogen can be used to provide back-up/emergency power or to secure a more reliable and higher quality power supply.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"168 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115266933","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mounting the catalytic converter (DOC) at or near the exhaust manifold helps to reduce the increase in emission after a cold engine is started. The spike occurs because cold engines require a richer air-fuel mixture to run smoothly. The emission standards can be met only by appropriate design of catalytic converter along with the thin walled substrate for faster light off of the catalyst. Further the low exhaust gas temperature experienced on light commercial diesel vehicle present a very challenging environment for the successful operation of Diesel Oxidation Catalyst (DOC). Therefore to reduce HC, CO and PM engine demands catalyst with high oxidation activity at low temperatures. Consequently with ultra thin walls and PGM coatings significant improvements in DOC efficiency is achieved at low cost, by increased geometric surface area, reduced thermal mass and Precious Group Metals (PGM) formulation. In this present study, a computational analysis is carried out to design and optimize the DOC PGM loadings and experimentally design is validated by meeting the emission norms. The engine employed for this experimental activity is a 3 cylinder, CR diesel engine.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123421044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HCCI engines operates on the principle of having a dilute, premixed charge that reacts and burns volumetrically throughout the cylinder as it is compressed by the piston. In some regards, HCCI incorporates the best features of both spark ignition (SI) and compression ignition (CI) engine, the charge is well mixed, which minimizes particulate emissions, and as in a CIDI engine, the charge is compression ignited and has no throttling losses, which leads to high efficiency. However, unlike either of these conventional engines, the combustion occurs simultaneously throughout the volume rather than in a flame front. This important attribute of HCCI allows combustion to occur at much lower temperatures, dramatically reducing engine-out emissions of NOx. But, the pure CNG fueled HCCI engine successfully operates only in a narrow range of conditions bounded by severe knock on the fuel-rich side and lean misfire on the lean side and high NOx emission. It was found that RG blending with base CNG fuel in HCCI engine produces wider operating range towards lean burn boundary. Replacing CNG with RG increases measured combustion efficiency, particularly for leaner mixture. Boost pressure increases air/fuel ratio and thus increases the thermal mass to be heated by the combustion heat release resulting in expanding operating region towards high load range and reduction in exhaust emission.","PeriodicalId":123922,"journal":{"name":"Frontiers in Automobile and Mechanical Engineering -2010","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116784151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
