Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...

AbstractStringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. The oxygenated fuel used is dibutyl ether(DBE). While injection pressure is 200 bar and injection timing is 20.5 0 BTDC we get higher brake thermal efficiency and lower brake specific fuel consumption for DBE10 compare to diesel.

The knowledge of the actual engaged gear is essential to achieve highquality control of an automotive power train. In cars equipped with manual gear shift, this information is not directly available. A hybrid observer for on–line identification of the actual engaged gear is proposed. Two hybrid models of an automotive driveline, a detailed one for verification and a reduced-order one for synthe...

This paper provides a comprehensive review of the technical feasibility of DME-Diesel blend as an alternative fuel for compression-ignition engines for automotive applications. DME is a synthetic fuel produced by the conversion of various feedstocks such as natural gas, coal, oil residues and bio-mass. The compatible properties such as high cetane number and low auto-ignition temperature with s...

Introduction Currently, one of the major drawbacks of Diesel engines compared to classic gasoline engines is their noise. Legislation on maximum noise levels is becoming more stringent all over the world, and the demand for quiet engine designs is growing day by day. For these reasons, many efforts are being undertaken in order to reduce this disadvantage, especially as acoustical comfort now b...

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...

Use of liquefied petroleum gas (LPG) in compression-ignition (C-I) engines has always been considered important in the diesel engineering field. This is due to its easy accessibility and good combustion characteristics. In this paper the application of LPG fuel along with diesel oil in a direct- injection automotive diesel engine is experimentally investigated. In order to convert the pure dies...

Theoretical models play an important role in the design of engine control and diagnostic systems, allowing to reduce development time and costs. The paper describes a control-oriented theoretical model for the simulation of an automotive Diesel engine built up using a “simulation library” developed in Simulink environment. Library blocks, defined for engine components and subsystems, were assem...

As compared to petroleum diesel, biodiesel is more corrosive for automotive materials. Studies on the characterization of corrosion products of fuel exposed automotive materials are scarce. Automotive fuel system and engine components are made from different ferrous and non-ferrous materials. The present study aims to investigate the corrosion products of different types of automotive materials...

Treatment of NOx in diesel engine exhaust represents a big opportunity for the environmental application of low-temperature plasmas. In this paper NOx conversion to N2 was investigated by Plasma/Catalyst System Catalytic activity was enhanced by the assistance of plasma ,and the plasma/Catalyst system showed higher NOx conversion. It is shown that the plasma by itself cannot chemically reduce N...
