The development of statistical analysis has played an important part in studying large data that captured from engine block as apart of engine monitoring and diagnose . Within this paper the application of statistical analysis was introduced by utilizing Kurtosis, I-kaz coefficient, and Crest Factor and Skewness parameter. There is potential that these statistical parameters could serve as patt...

this paper is the representation of the computational and experimental methods of a new injector nozzle for a sequential port injection cng engine. the objective of this study was to review the previous research in the development of gaseous fuel injector for port injection cng engine converted from diesel engine. next, a simulation of the fuel flow of the new injector nozzle was made using flu...

Biomaterials are low cost,easily transportable and biodegradable with time.Few exampls are cellulose,chitoson and gelatin. Here we used cellulose as a base material for designing box type sensor using Comsol Tool for the detection of bio-analytes such as engine oil,ethnal,gasoline and mercury.Results shown that differential deflection and resonant frequency as found among tested analytes.Highes...

nowadays biodiesel is receiving more attention as a most important renewable energy for using in diesel engines. inthis research, the application of response surface methodology (rsm) was highlighted to investigate the effects of biodiesel-diesel blends (b0, b20, b50 and b100), engine operating parameters (engine load and  speed) on co2 emission of a diesel engine. the experiments were conducte...

Oil pump in diesel engine has significant effect on energy consumption and environment pollution. In this paper, the modeling and simulation of a gear oil pump used in a diesel engine and its fluid flow analysis by a solver has been explained. Also the optimization and redesign of it has been discussed and then the outcomes have been compared with the experimental and previous results. The t...

Turbocharged CNG engines produce high NOx emission due to the fuel type and high combustion temperature. In this research, the effects of lean-burn and waste gate opening pressure threshold on NOx emission are studied theoretically and experimentally at WOT condition as well as 13-mode ECE-R49 test cycle. A code is developed in MATLAB environment for predicting engine NOx and the results are va...
