The main Carburetor functions are: • To form a proper homogeneous inflammable mixture of fuel and air • To supply the engine with varying amounts of this mixture The fuel-air mixture is formed through vapourising and by uniformly spraying fuel into the airstream or at least by atomising it into very small droplets. Atomization takes place in this way: liquid fuel from the atomiser nozzle meets the flow of air which carries it, broken into very fine droplets, to the combustion chamber. We have spoken of a “proper” mixture because the mixture strength, defined as the amount of air in weight mixed with a fuel unit of weight, must have a precise value, ie it must be within the limits of inflammability so that the mixture can be easily ignited by the spark in the combustion chamber. lnflammmability limits for commercial petrol are: 7: 1 (rich limit ie. 7 kgs of air and 1 kg of petrol) , down to 20: 1 (lean limit ie. 20 kgs of air and 1 kg of petrol) . To obtain optimum combustion between these inflammability limits, a value very close to the so- called stoiciometric value is needed ie. about 14.5 – 15.0 kgs of air to 1 kg of petrol. A stoiciometric mixture ratio is one which ensures complete combustion of fuel with only the formation of water and carbon dioxide. The stoiciometric mixture ratio depends on the kind of fuel used, so if the fuel is changed, this fuel- air ratio will also change (see SECTION 5.1 ) .

EMISSION CONTROL SYSTEMS FUEL INJECTION SYSTEM SV1000S motorcycles are equipped with a fuel injection system for emission level control. This fuel injection system is precision designed, manufactured and adjusted to comply with the applicable emission limits. BEFORE-PRESSURIZED FUEL PRESSURIZED FUEL * I’ RELIEVED FUEL ~%~~~ Ift 0 0 9 0 0 0 EMISSION CONTROL INFORMATION 9-3 CRANKCASE EMISSION CONTROL SYSTEM The engine is equipped with a PCV system . Blow-by gas in the engine is constantly drawn into the crankcase, which is returned to the combustion chamber through the breather hose, air cleaner and throttle body . C * FRESH AIR FUEL/AIR MIXTURE 411111110 BLOW-BY GAS 9-4 EMISSION CONTROL INFORMATION EXHAUST EMISSION CONTROL SYSTEM (PAIR SYSTEM) The exhaust emission control system is composed of the PAIR system and THREE-WAY CATALYST system. The fresh air is drawn into the exhaust port with the PAIR solenoid valve and PAIR reed valve . The PAIR solenoid valve is operated by the ECM, and the fresh air flow is controlled according to the TPS, ECTS, IATS, ZAPS and CKPS. H02 sensor (Except for USA) I 0 0 0 0 0 NOISE EMISSION CONTROL SYSTEM TAMPERING WITH THE NOISE CONTROL SYSTEM PROHIBITED : Federal law prohibits the following acts or the causing thereof: 1. The removal or rendering inoperative by any person, other than for purposes of maintenance, repair or replacement, of any device or element of design incorporated into any new vehicle for the purpose of noise control prior to its sale or delivery to the ultimate purchaser or while it is in use, or 2. The use of the vehicle after such device or element of design has been removed or rendered inoperative by any person. AMONG THOSE ACTS PRESUMED TO CONSTITUTE TAMPERING ARE THE ACTS LISTED BELOW : • * Removing or puncturing the muffler, baffles, header pipes, screen type spark arrester (if equipped) or any other component which conducts exhaust gases . • * Removing or puncturing the air cleaner case, air cleaner cover, baffles or any other component which conducts intake air . • * Replacing the exhaust system or muffler with a system or muffler not marked with the same model specific code as the code listed on the Motorcycle Noise Emission Control Information label .

TERMS AND DEFINITIONS OF FUEL INJECTION MANAGEMENT SYSTEMS

Throttle Body Assembly (TBA) — The throttle body assembly (also called air valve), controls the airflow to the engine through one, two or four butterfly valves and provides valve position feedback via the throttle position sensor. Rotating the throttle lever to open or close the passage into the intake manifold controls the airflow to the engine. The accelerator pedal controls the throttle lever position. Other functions of the throttle body are idle bypass air control via the idle air control valve, coolant heat for avoiding icing conditions, vacuum signals for the ancillaries and the sensors. FUEL INJECTOR — There are basically three approaches in delivering the fuel to the engine: • Above the throttle plate as in throttle body injection • In the intake port toward the intake valves as in multi-port injection or central multi-port injection. • Directly into the combustion chamber as in gasoline direct injection systems (GDI). The fuel injector is continuously supplied with pressurized fuel from the electric fuel pump. The pressure across the metering orifice of the injector is maintained constant by the fuel pressure regulator. The fuel injector is an electromagnetic valve that when driven by the ECU delivers a metered quantity of fuel into the intake manifold (or combustion chamber in the GDI system). The ECU controls the fuel flow by pulse width modulation. The time the injector is driven into an open condition is determined by the following sensor inputs: • Engine RPM • Throttle position (TPS) • Manifold absolute pressure or mass air flow • Engine coolant temperature • Oxygen sensor feedback voltage • Intake air charge temperature • Battery voltage CENTRAL POINT INJECTION SYSTEM (CPI) — Electronic fuel Injection system consisting on a single fuel injector mounted in the throttle body. DIGITAL FUEL INJECTION (DEFI OR DFI) — Electronic fuel injection system controlled by digital microprocessors as opposed to earlier systems that were of analog design. The analog input signals to the microprocessor are converted from analog to digital before being processed.
