2. SUPPLY PUMP
2.1 Outline
The supply pump equipped with the 4N13 and 4N14 engines is compliant with pressures up to 200 MPa.
The supply pump uses an SV3 type Suction Control Valve (SCV.)
Operation Section1–4
2.2 Suction Control Valve (SCV)
When the solenoid in the SCV is not energized, the return spring pushes against the needle valve,
completely opening the fuel passage and supplying fuel to the plungers. (Total quantity suctioned Total
quantity discharged)
When the solenoid in the SCV is energized, the armature pushes the needle valve, compressing the return
spring and closing the fuel passage.
The solenoid is actuated ON and OFF by duty ratio control. Fuel is supplied in an amount corresponding to
the open surface area of the passage in response to the duty ratio. The fuel is then discharged by the
plungers.
(1) Duty ratio control
• The engine ECU outputs sawtooth wave signals with a constant frequency. The current value is the
effective (average) value of these signals. As the effective value increases, the valve opening decreases.
Conversely, as the effective value decreases, the valve opening increases.
Operation Section1–5
(2) When the SCV energization duration (duty ON time) is short
• When the SCV energization time is short, the average current flowing through the solenoid is small. As a
result, the needle valve is returned by spring force, creating a large valve opening. Subsequently, the fuel
suction quantity increases.
(3) When the SCV energization duration (duty ON time) is long
• When the energization time is long, the average current flowing to the solenoid is large. As a result, the
needle valve is pressed out (in the compact SCV, the needle valve is pulled), creating a small valve
opening. Subsequently, the fuel suction quantity decreases.
Operation Section1–6
2.3 Fuel Temperature Sensor
The fuel temperature sensor detects the fuel temperature, and sends a corresponding signal to the engine
ECU. Based on this information, the engine ECU calculates the injection volume correction that is
appropriate for the fuel temperature.
Operation Section1–7
3. RAIL
3.1 Outline
The rail used in the CRS equipped with the 4N13 and 4N14 engines has a system pressure of 200 MPa.
As such, a rail pressure sensor and pressure limiter are used that comply with the system pressure.
3.2 Rail Pressure Sensor (Pc Sensor)
The rail pressure sensor (Pc sensor) detects the fuel pressure of the rail, and sends a signal to the engine
ECU. The sensor is made from a semiconductor that uses the Piezo resistive effect to detect changes in
electrical resistance based on the pressure applied to the elemental silicon. In comparison to the old model,
this sensor is compatible with high pressure.
Operation Section1–8
3.3 Pressure Limiter
The pressure limiter releases pressure when the internal rail pressure becomes abnormally high. The
pressure limiter opens when internal pressure reaches 241 MPa (2458 kg/cm2), and closes when rail
pressure reaches a given set value. Fuel released from the pressure limiter is returned to the fuel tank.
Operation Section1–9
4. INJECTOR
4.1 Outline
G3 injectors are used in the CRS equipped with the 4N13 and 4N14 engines. G3 injectors comply with a
system pressure of 200 MPa, and were designed to show improved responsiveness, as well as to increase
resistance against foreign material adherence to the nozzle.

5.2 Engine Electronic Control Unit (ECU)
The engine ECU is the command center that controls the fuel injection system and overall engine operation.
Operation Section1–13
5.3 Sensor Operation
(1) Mass Air Flow (MAF) meter
• The MAF meter used in the CRS equipped with the 4N13 and 4N14 engines is a plug-in type, and is
constructed so that a portion of the intake air flows through detector of the meter. Directly measuring the
quantity and flow volume of the intake air improves detection accuracy, and decreases intake air
resistance.
• The MAF meter is built into the intake air temperature sensor.
(2) Manifold Absolute Pressure (MAP) sensor
• The MAP sensor is a semiconductor pressure sensor that utilizes changes in electrical resistance that
occur when the pressure applied to a silicon crystal changes. The MAP sensor uses a VSV to alternate
between atmospheric pressure and manifold absolute pressure so that a single sensor can perform both
pressure measurements.
Operation Section1–14
(3) Diesel throttle
Outline• The diesel throttle is interlocked with the key switch to reduce vibration when the engine is stopped by
blocking the intake of air.

Operation Section1–15
6. FUEL INJECTION CONTROL
6.1 Outline
The following explains the types of fuel injection control used in MITSUBISHI vehicle systems. For details
on each type of control, refer to "General Edition Manual: Common Rail System (Doc ID: 00400076E)."
Fuel injection rate control function• The fuel injection rate control function regulates the amount of fuel discharged from the injector orifice per
unit of time.
Fuel injection quantity control function• The fuel injection quantity control function replaces the conventional governor function. Fuel injection
quantity control adjusts the fuel injection to the optimal injection quantity based on the engine speed and
accelerator position signals.
Fuel injection timing control function• The fuel injection timing control function replaces the conventional timer function, and controls the
injection to an optimal timing based on the engine rotational speed and the injection quantity.
Fuel injection pressure control function (rail pressure control function)• The fuel injection pressure control function (rail pressure control function) controls the discharge volume
of the pump by measuring the fuel pressure at the rail pressure sensor and feeding a signal back to the
ECU. Pressure feedback control is performed so that the discharge volume matches the optimal
(command) value set in accordance with the engine rotational speed and the injection quantity.
6.2 Fuel Injection Quantity Control
The following explains controls unique to MITSUBISHI vehicles. For other types of basic fuel injection
quantity control, refer to "General Edition Manual: Common Rail System (Doc ID: 00400076E)."
(1) Maximum injection quantity
• The basic maximum injection quantity is determined by the engine rotational speed, the added
corrections for intake air pressure, and gear position.
Operation Section1–16
(2) Idle speed control (ISC) system
• The ISC system controls the idle speed by regulating the injection quantity so that the actual speed
matches the target speed calculated by the engine ECU.
• The target speed varies depending on whether the A/C is on or off, and the coolant temperature.
Operation Section1–17
6.3 Other Controls
The following explains microinjection quantity learning control.
(1) Microinjection quantity learning control
Outline• Microinjection quantity learning control is used in every vehicle engine (injector) to preserve the accuracy
of the quantity (specifically, the pilot injection quantity.)
This type of control is first performed when shipped from the factory (L/O), and later is automatically
performed every time the vehicle runs a set distance (for details, see item "(A)” below). Microinjection
quantity learning control not only preserves the accuracy of each injector initially, but also as deterioration
in injection occurs over time. Microinjection quantity learning also records the correction values to the
ECU. During normal driving operations, these correction values are used to make modifications to
injection commands, resulting in accurate microinjection.
Learning operations• Microinjection quantity learning control takes place for every two no-load, idle instability conditions
established (see chart "(A)" below). This control can also be performed manually as a diagnostic tool.
Operation Section1–18
Operational outline• Learning control sends ISC (target speed correction quantity) and FCCB (cylinder-to-cylinder correction
quantity) feedback based on engine speed to apply injection control. Corrections are applied to each
cylinder based on ISC and FCCB correction information, and the corrected injection quantities are
calculated. Under microinjection quantity learning control, injection is divided into five injections.
Therefore, the "learning value" is calculated as the corrected injection quantities for ISC and FCCB,
divided by five injections.
Operation Section1–19
7. OTHER SYSTEMS
7.1 Diesel Particulate Filter (DPF) System
OutlineFor details on basic DPF construction and operation, refer to "General Edition Manual: Common Rail
System (Doc ID: 00400076E)". The differential pressure sensors and exhaust gas temperature sensors in
the systems for the applicable vehicles are DENSO products.
Differential pressure sensorThe construction and operation of the current differential pressure sensor is identical to that of the
conventional differential pressure sensor. The differential pressure sensor detects the difference in exhaust
gas pressure across the DPF.
Exhaust gas temperature sensorsThe construction and operation of the current exhaust gas temperature sensors is identical to that of the
conventional differential pressure sensor. The exhaust gas temperature sensors detect the temperature of
the exhaust gas both before and after the DPF.
Operation Section1–20
7.2 Fuel Filter with Filter Clog Switch, In-Tank Pump
Fuel filter with filter clog switchThe filter clog switch detects filter clogs using the pressure difference between the fuel filter inlet and outlet.
When a filter clog is detected, a diagnostic signal is outputted. (The fuel filter with filter clog switch is made
by DENSO.)
In-tank pumpThe CRS equipped with the 4N13 and 4N14 engines uses an in-tank pump. The in-tank pump sends fuel
from inside the fuel tank to the supply pump, thereby assisting the pump in suctioning fuel to stabilize the
feed pressure. (The in-tank pump is made by another company.)
