Depleting oil reserves and the growing concerns of global warming, have made it compulsory to seek alternative in form of environment friendly technologies like renewable energy sources. The advantage of hybrid power systems is the combination of the continuously available diesel power and locally available, pollution-free wind energy. With the Wind-Diesel hybrid power system, the annual diesel...

BACKGROUND Diesel exhaust (DE) exposures are very common, yet exposure-related symptoms haven't been rigorously examined. OBJECTIVE Describe symptomatic responses to freshly generated and diluted DE and filtered air (FA) in a controlled human exposure setting; assess whether such responses are altered by perception of exposure. METHODS 43 subjects participated within three double-blind cros...

Effect of organic compounds on nanoparticle formation in diluted diesel exhaust U. Mathis, M. Mohr, and R.

This study investigated the emission characteristics of ultrafine particles based on test bench and on-board measurements. The bench test results showed the ultrafine particle number concentration of the diesel engine to be in the range of (0.56-8.35) x 10(8) cm(-3). The on-board measurement results illustrated that the ultrafine particles were strongly correlated with changes in real-world dri...

diesel exhaust particles are a complex mixture of thousands of gases and fine substances that contain more than 40 different environmental contaminants. being exposed to these exhaust particles (called soot) can cause lung damage and respiratory problems. diesel particulate filters are used in many countries for mobile sources as a legal obligation to decrease harmful effect of these fine parti...

Due to diminishing petroleum reserves and the environmental negative effects of exhaust gases from diesel engines, alternative fuels for diesel engines are becoming increasingly important Egyptian waste cooking oils have special specifications because it expose to high temperatures during use for long hours. In the present experimental study, the performance and emissions of a four strokes, sin...

Evaluations of air quality impacts from vehicle emissions are based on the assumptions that all the important reactive species in the exhaust have been identified and quantified and that they are accurately represented in airshed models. To test this, environmental chamber experiments were carried out with exhaust from vehicles fueled by LPG, M100, M85, CNG, diesel, and Phase 2 reformulated gas...

Regarding the power, the efficiency and the discharge questions of the low-speed diesel engine, this article studied emphatically the Miller cycle, the analysis technology for the air intake system, and the matching technology for the intake and the exhaust. On the foundation of the twin inlet structure the paper analyzed the intake swirl control area and its influence to the gas charging effic...
