Abstract: An exhaust system of the internal combustion engine is provided, which includes an exhaust manifold mounted in a multiple cylinder engine of the internal combustion engine and configured to expel air burned in the cylinder when an exhaust valve is opened, a plurality of exhaust pipes connected to the exhaust manifold and configured to dispense an exhaust gas to the outside, a muffler and a plurality of exhaust balancers configured to function as a condenser are selectively mounted in the exhaust system so as to fill a part of the exhaust gas inside and then re-exhaust the filled exhaust gas when the exhaust is completed. The exhaust system improves a power of the engine by lowering exhaust pressure generated from exhaust resistance than that of the cylinder.

Abstract: The present invention provides an intake system for supplying intake air to a multiple cylinder internal combustion engine. The intake system includes an air intake having a suction pipe with a frame therein and a plurality of wings attached to the frame wherein the wings generate a swirl state in the intake air. The system further includes an air cleaner, an intake pipe, an intake manifold having a surge tank, a plurality of first suction chambers and a plurality of first suction balancers. The system also includes a second suction chamber and a second suction balancer. The second suction balancer is configured to accommodate intake air that flows reversely through the second suction chamber and the second suction chamber is configured to mix the intake air from the air intake and the intake air from the second suction balancer and dispense mixed air to an intake port of the engine. The system provides for sufficient air intake at a vast range of engine speeds and loads.
