Cooler Fuel Tank Q004457E Operation Section 1– SUPPLY PUMP 2.1 Change Item z The supply pump Suction Control Valve (SCV) has been changed from the SV2 type to the SV1 type (Refer to [SCV types (SV1, SV2)] on P1-7.) to Fuel Tank to Fuel Tank to Rail from Fuel Tank SCV Fuel Temperature Sensor Fuel Temperature Sensor Q004458E 2.2 Suction Control Valve (SCV) z The supply pump is equipped with a normally closed type SCV z When the solenoid is energized, the needle valve is pressed upon (in the compact SCV, the cylinder is pulled upon) by the armature, completely opening the fuel passage and supplying fuel to the plunger (Total quantity suctioned → Total quantity discharged) z When power is removed from the solenoid, the return spring presses the needle valve back to the original position, closing the fuel passage z The solenoid is actuated by duty ratio control Fuel is supplied in an amount corresponding to the open surface area of the passage, which depends on the duty ratio The fuel is then discharged by the plungers Needle Valve Armature Return Spring Valve Body Solenoid Q004459E 1– Operation Section Feed Pump Plunger Cylinder Supply Pump SCV Q002505E Operational

SCV types (SV1, SV2) • The SCV is available in the SV1 type and SV2 type The SV2 is a compact SCV, while the SV1 is a bit larger than the SV2 SV1 Type SCV SV2 Type SCV Q003726E Operation Section 1– 14 (2) Control outline • The difference between the final injection quantity and the actual injection quantity are learned based on the loop in the figure below Next, the following two items are compared: 1) the results of the actual injection quantity estimate based on the ideal state for NE input, and 2) the results of the actual injection quantity estimate based on the actual NE input (detected value.) Difference Between Both Values Learned Command Injection Quantity Actual Injection Quantity Command Output Wide-Range Injection Quantity Learning Actual Rotational Speed Rotational Speed Output
