Fuel properties of loofah oil and its ethyl ester blended with diesel were experimentally determined. Biodiesel blends (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100%) of loofah oil and its ethyl ester by volume with diesel was used. The fuel properties of the biodiesel blends were determined according to American Society for Testing and Materials (ASTM) standards. Pure Automotive Gas Oil (AGO) wa...

--Stringent emission norms and environment degradation due to pollutants from the automotive vehicles lead us to find the suitable alternative for the petro-diesel. Among the alternatives the non-edible vegetable oil seems to be most promising one. When the vegetable oil is used as fuel in diesel engine, it does not cause any major problem if used for a short period. However in the long run it ...

In the wake of growing concerns over petroleum supplies and air pollution, electric vehicles (EVs) – including hybrid electric vehicles (HEVs) – are being developed and refined as cost-effective, reliable and safe alternatives to conventional gasoline and diesel engines. The race is on to design electric batteries as the power source for this new class of vehicles. Competition is intense and th...

The FDI approach to model-based diagnosis is considered. We present a method for residual generation that combines integral and derivative causality, and also utilizes equation system solvers and theory of differential-algebraic equation systems. To achieve this, a framework for computation of variables from sets of dependent differential and/or algebraic equations is introduced. The proposed m...

The MEMS pressure sensor has been introduced and presented in this paper. The types of pressure sensor and its theory of operation are also included. The latest MEMS technology, the fabrication processes of pressure sensor are explored and discussed. Besides, various device applications of pressure sensor such as tire pressure-monitoring system, diesel particulate filter and others are explaine...

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...

A full 3D numerical simulation of the two-phase flow made up (bio)diesel and particles, has been carried out to reproduce deposition pattern particles in a BOSCH automotive filter. From probability density function (PDF), simple Eulerian-Eulerian model is proposed for diesel particles. The formulation allows detailed description relationship between velocity size Brinkman-Darcy approximation co...
