Engine oil consumption is an important source of hydrocarbon and particulate emissions in modem automobile engines. Great efforts have been made by automotive manufacturers to minimize the impact of oil consumption on engine emissions. Research engineers in the last decade have been trying to study the sources and driving mechanism of oil consumption. In contrast to oil consumption mechanisms i...

With the rapid development of automobile industry, number automobiles in China has exceeded 290 million. The increase car ownership promoted auto repair industry to a certain extent, but it is an indisputable fact that overall level China’s low. In recent years, performance engines been rapidly developed, not only power and horsepower have greatly improved, also reliability engine failure still...

The requirement for the advancement of internal combustion (IC) engines and enhance methods cycle is increasing day by day. four-stroke engine extensively used due to better fuel economy less exhaust smoke. However, major drawback includes a considerable amount extra heat energy generation that directly adds up waste energy. In order overcome limitation, idea computing two strokes in utilize ha...

Various research groups across the globe have developed models for engine condition monitoring and fault diagnosis based on the data from steady state performance measurements over the last two decade. However, these performance data are not amenable for easy collection in some situations and some of the data may show little performance deviation at the steady state conditions of operation. In ...

The exhaust system has a number of requirements to fulfil. The major ones are to reduce the noise level created by the engine, to channel the waste gases out the rear of the automobile, to minimize the reduction in engine performance, and to have an acceptable service life and cost1. The exhaust system is divided into two main parts, the hot end and the cold end. The components comprising the h...

In order to meet the recently enhanced emission standards at home and abroad, it is necessary to develop the CRDI ECU control algorithm that users can adjust fuel injection timing and amount in response to their needs. Therefore, this study developed the simulator for knocking analysis that enables knocking discrimination and engine balance correction applicable to the ECU exclusive to the indu...

The rising complexity of modern automotive engines with an increasing number of actuators and sensors to minimise emissions and fuel consumption and to maximise engine driveability require a detailed supervision for fault detection and on-board diagnosis. The European Community Directive 98/69/EC requires on-board diagnosis for spark ignition engines and will require it for diesel engines as of...

After the oil crisis of the 1970's, stringent government standards placed on automobile manufacturers have led the industry to explore more fuel efficient alternatives to the vehicle with a conventional internal combustion engine/transmission powertrain. This is the motivation behind Mr. David F. Moyer's hybrid internal combustion engine concept. A vehicle using this engine should attain higher...
