    FEATURES EAS20170 FEATURES EAS15B1002 OUTLINE OF FI SYSTEM The main function of a fuel supply system is to provide fuel to the combustion chamber at the optimum air-fuel ratio in accordance with the engine operating conditions. In a conventional carburetor system, the air-fuel ratio of the mixture that is supplied to the combustion chamber is created by the volume of the intake air and the fuel that is metered by the jet used in the respective chamber.
  • Page 12: Fi System

    FEATURES EAS15B1003 FI SYSTEM The fuel pump delivers fuel to the fuel injector via the fuel filter. The pressure regulator (in the fuel pump) maintains the fuel pressure that is applied to the fuel injector at 240 – 260 kPa (2.40 – 2.60 kg/cm 34.1 –...
  • Page 13: Outline Of Anti-Lock Brake System (Xp500A)

    The operation of the Yamaha ABS brakes is the same as conventional vehicle, with a right hand brake lever for operating the front wheel brake and a left hand brake lever for operating the rear wheel brake.

  • Page 15 FEATURES 0%: There is no slip between the wheel and the road surface. The chassis speed is equal to the wheel speed. 100%: The wheel speed is “0”, but the chassis is moving (i.e., wheel lock). EAS15B1006 Brake force and vehicle stability When the brake pressure is increased, wheel speed is reduced.
  • Page 16 FEATURES EAS15B1008 ABS operation and vehicle control If the ABS starts operating, there is a tendency of the wheel to lock, and the vehicle is approaching the limit of control. To make the rider aware of this condition, the ABS has been designed to generate a reaction-force pulsating action in the brake lever.
  • Page 17 FEATURES sure. But, if there is a tendency of the wheel to lock on a slippery road surface, due to engine braking, the ABS may not be able to prevent the wheel from locking. EWA15B1004 WARNING The ABS controls only the tendency of the wheel to lock caused by applying the brakes. The ABS cannot prevent wheel lock on slippery surfaces, such as ice, when it is caused by engine braking, even if the ABS is operating.
  • Page 18 FEATURES Electronic control unit (ECU) The ECU (ABS) “1” controls the ABS and is located on the right side of the vehicle near the top of the front fork. To protect the ECU (ABS) from water damage, it is protected by a cover. ABS control operation The ABS control operation performed in the ECU (ABS) is divided into the following two parts.

Self-diagnosis (when static) A. 8/1,000 of a second 5. Self-diagnosis (when riding) Fail-safe relay The fail-safe relay controls the power supply of the hydraulic unit and is located upper the ECU (ABS). 1.
  • Page 20 FEATURES Composition and operation The fail-safe relay is composed of the solenoid relay “1” and fail-safe relay “2”. The solenoid relay is activated (continuous) by signals transmitted from the ECU (ABS). As a result, the solenoid valve “3” can be operated. If a malfunction occurs in the circuit, the solenoid relay is deactivated and it becomes impossible for the solenoid valve to reduce the hydraulic pressure of the brake fluid and normal braking is resumed.
  • Page 21 FEATURES ABS operation The ABS hydraulic circuit consists of two systems: the front wheel and rear wheel. The following de- scribes the front system only. Normal braking (ABS not activated) When the ABS is not activated port D “11” of the solenoid valve is closed because a control signal has not been transmitted from the ECU (ABS) and port A “7”...
  • Page 22 FEATURES Emergency braking (ABS activated) 1.Depressurized state When the front wheel is about to lockup, port D “11” of the solenoid valve is opened by the “depres- surization” signal transmitted from the ECU (ABS). When this occurs, the spool of the flow control valve compresses the return spring to close port B “9”.
  • Page 23 FEATURES 2.Pressurized state Port D “11” is closed by the “pressurization” signal transmitted from the ECU (ABS). Before this oc- curs, the spool of the flow control valve has compressed the return spring to close port B “9”. Brake fluid that has entered through port A “7” is further restricted by the orifice “10” and the brake fluid is sent to the brake calipers via port A “7”...
