As a result, the quantity of fuel that is injected until main ignition occurs increases, resulting in an explosive combustion at the time of main ignition.Toggle navigation. The engine ECU calculates the basic injection quantity based on the engine operating conditions and driving conditions. The engine ECU performs the necessary calculations in accordance with the sensors installed on the engine and the vehicle. This closes the nozzle needle, and as a result, fuel is not injected. For this reason, the hydraulic pressure that is applied to the command piston causes the nozzle spring to compress. Page Qr Codes Operation Section - solenoid valve is pushed downward, effectively closing the outlet orifice.

The sensor is made from a semicon- ductor that uses the Piezo resistive effect to detect changes in electrical resistance based on the pressure applied to the elemental sili- con.
#COMMON RAIL FUEL INJECTION SYSTEM PPT PC#
The rail pressure sensor Pc sensor detects fuel pressure in the rail and sends a signal to the engine ECU, and the pressure limiter controls the excess pressure. A rail pressure sensor and a pressure limiter valve are adopted in the rail. Based on this information, the engine ECU calcu- lates the injection volume correction that is appropriate for the fuel temperature. With the rotation of the inner rotor, the feed pump draws fuel from its suction port and pumps it out through the discharge port.
The feed pump is driven by the drive shaft.
Multi Point Fuel Injection (MPFI)ĭue to the spring force, Plunger B is pulled in the opposite direction to Plunger A. The engine drives the supply pump at a ratio of The eccentric cam is connected to the ring cam. The two plungers are positioned vertically on the outer ring cam for compactness. Table of Contents Because the engine ECU controls the injection system injection pressure, injection rate, and injection timingthe injection system is independent, and thus unaffected by the engine speed or load.
