PENGARUH VARIASI DURASI CAMSHAFT TERHADAP UNJUK KERJA MOTOR BAKAR 4 LANGKAH
Abstract: To obtain maximum
engine performance one way to do is to do modification the camshaft . Changes
can be made to alter or modify the time to open and close the valve. As already
unknow that big power generated by the engine is affected by the amount of
residual gases that exit the combustion chamber. The amount of air and fuel
mixture entering the combustion gases and regulated by the duration of the
opening and closing of the valve.For it was necessary to study the extent to
which the effect of the change by the duration of the camshaft to the increased
power and torque of the engine, which can then be recovered size is definitely
the most appropriate duration to generate great power and torque. Effective
power produced at 220 ° camshaft duration variation is at 6000 RPM of 7.7 HP,
variations in camshaft duration 227 °, ie at 8.49 HP at 6500 RPM, variations in
camshaft duration 233 °, ie at 6500 RPM at 8.77 HP, variations in camshaft
duration 239 °, ie at 9.53 HP at 6500 RPM. Average turning moment - resulting
in maximum average variation of camshaft duration 220 °, ie at 6000 RPM of 1.37
Nm Variations camshaft duration 227 °, ie at 6000 RPM 1.43 Nm Variations
camshaft duration 233 °, ie at 1.47 Nm at 6000 RPM Variations camshaft duration
239 °, ie at 6500 RPM of 1.51 Nm
Keywords: effect of variations
in the duration of the camshaft, power, torque, and fc (fuel concumtion)
