The effects of motorcycle exhaust particulate on vasoconstriction were determined using rat thoracic aortas under organ culture conditions treated with organic extracts of motorcycle exhaust particulate from a two-stroke engine. The motorcycle exhaust particulate extract (MEPE) induced a concentration-dependent enhancement of vasoconstriction elicited by phenylephrine in the organ cultures of b...

An experimental study of the oxidation of CO in exhaust gas from a motorcycle has been carried out using plasma chemical reactions in a pulsed corona discharge. In the process, some main parameters, such as the initial CO concentration, amplitude and frequency of pulses, residence time, reactor volume, and relative humidity (RH), as well as their effects on CO removal characteristics, were inve...

One of the reasons for air pollution that occurs at this time is emission motorcycle exhaust. According to some sources, trembesi leaves can absorb level exhaust emissions. By making extracts from and added part motorcycle. Because last place discharge combustion waste process on motorcycles result when has not been leaf extract produce a Nitrogen Oxide (Nox) gases 0.21 ppm. While results are d...
