These methods can measure with a high accuracy and have proven its practicability in the fuel economy test, but require the test vehicle to be modified to supply hydrogen from an external, rather than the on-board fuel tank. As these vehicle modifications necessitate technical assistance of the vehicle manufacturer, a simpler no-modification method such as the carbon balance method for gasoline- and diesel-fuelled vehicles is desired. Therefore, the authors have developed new method using only FCV exhaust emissions. This paper describes the principles behind the new method as well as test equipment and results, influence factors in error and issues. As a result, its real-time fuel consumption measurement characteristics were improved by reducing the volume of the gas sampling system and by correcting the time lag in oxygen concentration analysis. Error of the new method was from -3% to +1% as compared with the flow method for the fuel cell system operating in JC08 test cycle.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"42 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88832568","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}

Human beings are faced with health challenges as they breathe air in their living environment. The breathing in of carbon monoxide has caused reduction of oxygen in take by man; because when carbon monoxide is breathed into the lungs, it sticks to the haemoglobin thereby preventing oxygen flow. This affects the transportation of oxygen by the blood which causes suffocation in man. The cluster of automobiles on roads and streets globally has posed health challenge. Hence this research is focused on finding solution to the effect of carbon monoxide CO on human health. To carry out this study the researcher used two automobiles that have different type of exhaust system. The researcher exposed four English rabbits to the two different exhaust systems in different rooms together with white fabrics in each of the rooms for one week to check for level of carbon deposits on the white fabrics after one week of the experiment. Observations were made in respect to body temperature, weight, nasal discharge, vomiting rate and feeding habits of the four rabbits used in the experiment. Findings were discussed based on observations as shown on records and recommendations were made to guide the researcher in making conclusion.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"7 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2016-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77067040","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}

AVLT enables engine power improvement by increasing valve timing and lift at high engine speed and load operating regions. It utilizes engine fluids pressure difference with respect to engine speed to actuate the AVLT mechanism which will make the valve lift higher and longer duration at higher engine speed and loads. Since engine speed and load can be linearly correlated to these pressures, a mechanical sliding arm valve actuation mechanism is constructed based on their transient behavior. Therefore, a continuously dynamic valve lift profile with respect to engine speed can be achieved to increase brake power of the engine. Dynamics analysis performed using MSC Adam software showed that tappet translation increased by 32% from 9.09 mm to 12.01 mm by varying translational skate position between 0o and 10o. The results from this simulation are then set as intake valve profile in Lotus Engineering software simulation. With AVLT, brake power at speed between 5000 and 6500 rpm increased between 2% to 7%. Maximum torque improvement was realized at 7000 rpm while BSFC was reduced by up to 2% at 7000 rpm. The increased in brake power and torque are direct results from volumetric efficiency linear improvement between 1.5 and 6% at speed range of 5000 to 7000 rpm.","PeriodicalId":7286,"journal":{"name":"Advances in Automobile Engineering","volume":"11 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2016-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76870583","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}
