This paper presents an investigation report of different components failure which affect the performance of an automobile engine. The premature breakage of a four cylinder diesel engine block, crankshaft, camshaft, crankshaft bearing, camshaft bush, engine oil pump was reported. It is found that the failure of each component having the same reason for its failure as reported from different plac...

The challenge for Automobile is present emission norms that demands engine for green environment with high performance and low emission. The Low Heat Rejection Engine (LHR Engine) is a technology, which minimizes heat loss to the coolant by providing heat resistance in the heat flow to the coolant. As LHR Engine is used, the heat is not transferred to the surroundings. Another method to improve...

With gasoline at a record $2.50 a gallon in the United States, and with the passage of the Energy Policy Act of 2005, now is a good time to see where the United States has been and where it might be heading in the near future, in regard to automobiles and government policies to regulate their efficiency. In this paper, I will first look at the recent history of American energy policy as applied...

This race is particularly visible in the automotive field. Companies around the globe are vying to build a new, less polluting automobile engine that does not run on gasoline. In the US, for instance, General Motors (GM) spent over US$1 billion on developing an electric car that runs on a hydrogen fuel cell. It originally chose hydrogen fuel as the basis for the engine. Yet mass production of a...

The shaft bearing is the key component of water pump and its fatigue failure results in abnormal operation system. However, mechanisms are still unclear. In this paper, analysis on engine was carried out by using measurement material composition properties, observation macro micro morphologies, theoretical failure. wear behavior were clarified, prevention measures further proposed. reflected fr...
