2. OUTLINE OF SYSTEM 2.1 Common Rail System Characteristics
The common rail system uses a type of accumulation chamber called a rail to store pressurized fuel, and injectors that c
tronically controlled solenoid valves to inject the pressurized fuel into the cylinders. Because the engine ECU controls t
system (injection pressure, injection rate, and injection timing), the injection system is independent, and thus unaffected b
speed or load. This ensures a stable injection pressure at all times, particularly in the low engine speed range, and dram
creases the amount of black smoke ordinarily emitted by a diesel engine during start-up and acceleration. As a result, exhau sions are cleaner and reduced, and higher power output is achieved.
2.2 Features of Injection Control (1) Injection Pressure Control • Enables high-pressure injection even at low engine speeds. • Optimizes control to minimize particulate matter and NOx emissions.
(2) Injection Timing Control
You'rewith Reading a Preview • Enables finely tuned optimized control in accordance driving conditions. (3) Injection Rate Control

3. SUPPLY PUMP 3.1 Outline
The supply pump consists primarily of the pump body (eccentric cam, ring cam, and plungers), SCV (Suction Control temperature sensor, and feed pump.
The two plungers are positioned vertically on the outer ring cam for compactness.
The engine drives the supply pump at a ratio of 1:1. The supply pump has a built-in feed pump (trochoid type), and dr from the fuel tank, sending it to the plunger chamber.
The internal camshaft drives the two plungers, and they pressurize the fuel sent to the plunger chamber and send it to
quantity of fuel supplied to the rail is controlled by the SCV, using signals from the engine ECU. The SCV is a normal (the intake valve opened during de-energization).

The pressure limiter releases pressure when the internal pressure of the rail becomes abnormally high. The pressure limiter
internal pressure reaches 221MPa (2254 kg/cm2) and closes when rail pressure reaches a given set pressure. Fuel releas pressure limiter is returned to the fuel tank.

(2) Injection
• When current is initially applied to the solenoid, the attraction force of the solenoid pulls the solenoid valve up, effectiv

• The fuel that flows past the outlet orifice flows to the leak pipe and below the command piston. The fuel that flows belo lifts the piston needle upward, which helps improve the nozzle's opening and closing response.

10. VARIOUS TYPES OF CONTROL 10.1 Outline
This system effects fuel injection quantity and injection timing control more appropriately than the mechanical governo
used in the conventional injection pump. The engine ECU performs the necessary calculations in accordance with the sens
on the engine and the vehicle. It then controls the timing and duration of time in which current is applied to the injectors realize both optimal injection and injection timing.
10.2 Fuel Injection Rate Control Function
Pilot injection control injects a small amount of fuel before the main injection.
10.3 Fuel Injection Quantity Control Function
The fuel injection quantity control function replaces the conventional governor function. It controls the fuel injection to injection quantity based on the engine speed and accelerator position signals.
10.4 Fuel Injection Timing Control Function You're Reading a Preview

10.5 Fuel Injection Pressure Control Function (Rail Pressure Contro tion)
The fuel injection pressure control function (rail pressure control function) controls the discharge volume of the pump by
the fuel pressure at the rail pressure sensor and feeding it back to the ECU. It effects pressure feedback control so that t volume matches the optimal (command) value set in accordance with the engine speed and the injection quantity.

11. FUEL INJECTION QUANTITY CONTROL 11.1 Outline
This control determines the fuel injection quantity by adding coolant temperature, fuel temperature, intake air temperatur
air pressure corrections to the basic injection quantity. The engine ECU calculates the basic injection quantity based on operating conditions and driving conditions.
11.2 Injection Quantity Calculation Method
The calculation consists of a comparison of the following two values: 1. The basic injection quantity that is obtained from t
pattern, which is calculated from the accelerator position and the engine speed. 2. The injection quantity obtained by ad types of corrections to the maximum injection quantity obtained from the engine speed. The lesser of the two injection used as the basis for the final injection quantity.

Fuel injection timing is controlled by varying the timing in which current is applied to the injectors.
12.2 Main and Pilot Injection Timing Control (1) Main Injection Timing
• The engine ECU calculates the basic injection timing based on the engine speed and the final injection quantity, and adds v of corrections in order to determine the optimal main injection timing.
(2) Pilot Injection Timing (Pilot Interval)
• Pilot injection timing is controlled by adding a pilot interval to the main injection timing. The pilot interval is calculated

• Learning control sends ISC (target speed correction quantity) and FCCB (cylinder-to-cylinder correction quantity) feedb
engine speed to apply injection control. The correction quantity is added to each cylinder based on ISC and FCCB corre mation. The corrected injection quantity is then calculated.
Through the use of quantity learning control, injection is divided into 5 injections. In this state, the value for ISC and FCC injection quantity that has been divided into five injections is calculated as the "learning value".

13. FUEL INJECTION RATE CONTROL 13.1 Outline
While the injection rate increases with the adoption of high-pressure fuel injection, the ignition lag, which is the delay fr
fuel is injected to the beginning of combustion, cannot be shortened to less than a certain value. As a result, the quantity
is injected until main ignition occurs increases, resulting in an explosive combustion at the time of main ignition. This in NOx and noise. For this reason, pilot injection is provided to minimize the initial ignition rate, prevent the explosive bustion, and reduce noise and NOx.
