CAR POLLUTION MEASUREMENT (A STUDY ON ‘HEALTH’ ENVIRONMENT)

ABSTRACT A fact that vehicles, especially cars both which use gasoline or diesel fuel significantly effect air pollution. Such a condition needs a measurement of the air pollution intensity as a basic of solution of the air pollution increase. Therefore the aim of this article is to study the measurements of: (1) engine CARB test; (2) constant volume sampling system (CVS); (3) driving cycle for emission test; and (4) engine exhause smoke. The method used is the study of the CARB test to measure gas emissions, where the cars are arranged on the chassis dynamometer that can stimulate the attraction following the road and cars are tensioned moisture; CVS system, in which a positive displacement fan draw air into the aqueous and mixing with the flue gas; then cycle for emission test, where the car is placed on a chassis dynamometer, starting from a cold engine and driven through the 23-minute driving cycle, and the engine smoke measurement performed on an experimental place, and the machine is turned on and then gassed, no load. The result of this study shows that for: (1) engine CARB test results a condition stimulation of continously speed and load vehicles in an engine test; (2) CVS with constituent results a light exhaust gas with a higher clean volume air, a less pollutant, and a good calculation and accurate; (3) driving cycle of emission test results a tighter emission control development; (4) smoke of engine for a certain speed and a maximum load results smoke concentration more accurate.
