This paper discusses engine performance and exhaust emissions based on the surface area of the cyclone. It is used as an attachment to the air duct before the intake manifold. The research aims to improve the level of mixing air with fuel, thereby improving fuel combustion. The research object is engine performance, intake manifold pressure, and waste emissions. engine performance is analyzed based on engine power and torque, while exhaust emission analysis is based on HC and CO2 gases. The intake manifold diameter of 54 mm is the result of the length of the cyclone blade, and the width of the cyclone blade is determined by values of 10 mm, 20 mm and 30 mm. The surface area of the cyclone blades is 810 mm2, 1620 mm2, and 2430 mm2. Then the cyclone is placed before the intake manifold, precisely at the throttle valve. The results obtained affect when adding a cyclone with a blade surface area of 1620 mm2 of 87 Hp at 5500 rpm engine speed and the resulting torque value of 312 Nm at 3500 rpm engine speed with the resulting average effective pressure of 1049 kPa or equivalent to 10 bar at 2500 rpm engine speed. Furthermore, the power produced and the use of a cyclone only affects high engine speed because the air and fuel flow produced is higher than when the engine speed is low. However, when the engine speed is too high, the power produced is low due to the possibility of the intake valve closing before the air and fuel flow into the cylinder. In the data of torque and average effective pressure that is generated along with the high engine speed, the resulting value is also low because the friction coefficient of the piston movement is large and the degree of filling of the cylinder decreases, resulting in low torque and the resulting average effective pressure.
