Energy storage devices for fluid power applications that are significantly more compact than existing ones will enable energy regeneration for many applications, including fluid power hybrid vehicles and construction equipment. The current approach to hydraulic energy storage makes use of a compressed gas enclosed in a closed chamber. As the system must contain the expanded gas and the hydrauli...

We conducted experiments to determine whether diesel engine exhaust affects reproductive endocrine function in growing rats. The rats were assigned to three groups: a group exposed to total diesel engine exhaust containing 5.63 mg/m3 particulate matter, 4.10 ppm nitrogen dioxide, and 8.10 ppm nitrogen oxide; a group exposed to filtered exhaust without particulate matter; and a group exposed to ...

This study was conducted to determine the impact of diesel exhaust inhalation on the fetus. Seventy-two pregnant rats and 18 nonpregnant rats were divided into three groups: a group exposed to total diesel engine exhaust containing 5.63 mg/m(3) particulate matter, 4.10 ppm nitrogen dioxide, and 8.10 ppm nitrogen oxide; a group exposed to filtered exhaust without particulate matter; and a group ...

Trends Light fossil fuel vehicles are now turning to electricity. The electric vehicle transition begins with a hybrid car. Hybrid uses an internal combustion engine as generator. Controller systems, driving safety and entertain light growing so that they consume lot of electricity, Safe devices lifestyle support. An additional battery charging system for car is being developed by the automotiv...
