2011 Kawasaki Teryx 750 FI 4x4 LE Owners Manual - Page 7

EMISSION CONTROL INFORMATION To protect the environment in which we all live, Kawasaki has incorporated crankcase emission (1), exhaust emission (2), and evaporative emission (3) control systems in compliance with applicable regulations of the United States Environmental Protections Agency and California Air Resources Board. 1. Crankcase Emission Control System A sealed-type crankcase emission control system is used to eliminate blow-by gases. The blow-by gases are led to the breather chamber through the crankcase. Then, it is led to the air cleaner. Oil is separated from the gases while passing through the inside of the breather chamber from the crankcase, and then returned back to the bottom of the crankcase. 2. Exhaust Emission Control System The exhaust emission control system applied to this engine family is engine modifications that consist of a fuel injection and ignition system having optimum ignition timing characteristics. The fuel injection has been calibrated to provide lean air/fuel mixture characteristics and optimum fuel economy with a suitable air cleaner and exhaust system. A maintenance free ignition system provides the most favorable ignition timing and helps maintain a thorough combustion process within the engine which contributes to a reduction of exhaust pollutants entering the atmosphere. 3. Evaporative Emission Control System The evaporative emission control system for this vehicle consists of low permeation fuel hoses and a fuel tank.
