2. Common Rail System Outline

2-1. Background to Development

•The common rail system was developed primarily to cope with exhaust gas regulations for diesel engines, and is a diesel injection control system with the following aims:

•To further improve fuel economy;

•To reduce noise;

•To achieve high power output.

2-2. System Characteristics

•The common rail system uses a type of accumulation chamber called a rail to store pressurized fuel, and injectors that contain electronically controlled solenoid valves to inject the pressurized fuel into the cylinders. Because the engine ECU controls the injection system (injection pressure, injection rate, and injection timing), the injection system is independent, and thus unaffected by the engine speed or load. This ensures a stable injection pressure at all times, particularly in the low engine speed range, and dramatically decreases the amount of black smoke ordinarily emitted by a diesel engine during start-up and acceleration. As a result, exhaust gas emissions are cleaner and reduced, and higher power output is achieved.

A.Injection Pressure Control

•Enables high-pressure injection even at low engine speeds.

•Optimizes control to minimize particulate matter and NOx emissions.

B.Injection Timing Control

•Enables finely tuned optimized control in accordance with driving conditions.

C.Injection Rate Control

•Pilot injection control injects a small amount of fuel before the main injection.

B. Operation

a.Supply Pump (HP3)

The supply pump draws fuel from the fuel tank, and pumps the high pressure fuel to the rail. The quantity of fuel discharged from the supply pump controls the pressure in the rail. The SCV (Suction Control Valve) in the supply pump effects this control in accordance with commands received from the engine ECU.

b.Rail

The rail is mounted between the supply pump and the injector, and stores the high-pressure fuel.

c.Injector (G2 Type)

This injector replaces the conventional injection nozzle, and achieves optimal injection by effecting control in accordance with signals from the engine ECU. Signals from the engine ECU determine the duration and timing in which current is applied the injector. This in turn, determines the quantity, rate and timing of the fuel that is injected from the injector. QR codes noting the characteristics of each vehicle are inscribed on the injector, and this data is sent to the ECU when the engine ECU or injectors are replaced. This enables software to be adjusted to the mechanical characteristics of each injector.

d.Engine ECU

The engine ECU calculates data received from the sensors to comprehensively control the injection quantity, timing and pressure.

3-3. Fuel System and Control System A. Fuel System

This system comprises the route through which diesel fuel flows from the fuel tank via the rail to the supply pump, and is injected through the injector, as well as the route through which the fuel returns to the tank via the overflow pipe.

B. Control System

In this system, the engine ECU controls the fuel injection system in accordance with signals received from various sensors. The components of this system can be broadly divided into the following three types: (a) sensors; (b) ECU; and (c) actuators.

a.Sensors

Detect the engine and driving conditions, and convert them into electrical signals.

b.Engine ECU

Performs calculations based on the electrical signals received from the sensors, and sends them to the actuators in order to achieve optimal conditions.

c.Actuators

Operate in accordance with electrical signals received from the ECU. Injection system control is undertaken by electronically controlling the actuators. The injection quantity and timing are determined by controlling the duration and timing in which current is applied to the TWV (Two-Way Valve) in the injector. Injection pressure is determined by controlling the SCV (Suction Control Valve) in the supply pump.

A.Outline

•The supply pump consists primarily of the pump body (camshaft (eccentric cam), ring cam, and plungers), SCV (Suction Control Valve), fuel temperature sensor, and feed pump.

SCV

Fuel Temperature Sensor

Q000570E

•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 draws the fuel 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 the rail. The quantity of fuel supplied to the rail is controlled by the SCV, using signals from the engine ECU. The SCV is a normally open type (the intake valve opens during de-energization).

E. Description of Supply Pump Components

a.Feed Pump

The trochoid type feed pump integrated into the supply pump, draws fuel from the fuel tank and feeds it to the two plungers via the fuel filter and the SCV (Suction Control Valve). The feed pump is driven by the camshaft. With the rotation of the inner rotor, the feed pump draws fuel from its suction port and pumps it out through the discharge port. This is done in accordance with the space that increases and decreases with the movement of the outer and inner rotors.

b.SCV (Suction Control Valve: Normally Open Type)

•A linear solenoid type valve has been adopted. The ECU controls the duty ratio (the duration in which current is applied to the SCV), in order to control the quantity of fuel that is supplied to the high-pressure plunger.

•The supply pump drive load decreases because intake fuel quantity is controlled to achieve the target rail pressure.

•When current flows to the SCV, the internal armature moves in accordance with the duty ratio. The fuel quantity is regulated by the cylinder, which moves in connection with the armature to block the fuel passage.

•With the SCV OFF, the return spring pushes the cylinder, completely opening the fuel passage and supplying fuel to the plungers. (Full quantity intake => full quantity discharge.)

•When the SCV is ON, the return spring contracts and closes the fuel passage.

•By turning the SCV ON/OFF, fuel is supplied in an amount corresponding to the drive duty ratio and then discharged by the plungers.

Регулировка зазоров клапанов на двигателе N04C, автомобиля HINO-300 производится на холодном двигателе.

Зазор впускного клапана 0.3мм

Зазор выпускного клапана 0.45мм

Снимаем клапанную крышку и выставляем метки на шкиве коленвала

!Метка на коленвале совпадает 2 раза через 360градусов, поэтому в зависимости от того, в каком цилиндре двигателя верхняя мертвая точка (1 или 4)

выбирается последовательность регулировки. Для того чтобы это понять достаточно убедится что впускные и выпускные клапана закрыты

Можно просто пошатать вверх вниз коромысла регулируемых клапанов чтобы понять последовательность по 1 или 4 цилиндру

они должны иметь свободный ход.

Последовательность регулировки клапанов если такт сжатия в первом цилиндре:

При таком порядке регулируются 1,2,3 и 6 клапаны (коромысла считаем от вентилятора)

Если такт сжатия в 4 цилиндре, то регулируем в последовательности показанной на следующей картинке

В таком положении регулируются 4, 5, 7, 8 клапаны

Зазор регулируется между носком коромысла и соединительным мостом клапанов, сразу для 2 клапанов

Контргайку регулировочного винта затянуть моментом 2.8-2.9 кгс*м

Прокладку клапанной крышки рекомендуется заменить новой. Вопросы задавайте в комментариях

Operation Section1–16

6.2 Engine ECU

General export vehicles for Europe, Oceania, and Asia use 12 V specification engine ECUs in relation to

the 24 V vehicle power supply (battery voltage). Accordingly, in the event that service such as repairs are

necessary, always verify the engine ECU specifications. To verify the specifications, look behind the

passenger seat back and check the engine ECU case, as well as whether or not there is a DC-DC converter.

< ATTENTION >When performing checks, do not apply vehicle power supply voltage to the engine ECU. If the

vehicle power supply voltage (24 V) is applied to a 12 V specification engine ECU, the ECU may be

damaged.

The figure below is an external view of the engine ECU. For the connector pin layout and external wiring

diagram: Refer to [Connector Terminal Layout] on P1-57.

Operation Section1–17

6.3 Electronic Drive Unit (EDU)

A conventional EDU is used with the NO4C-# engine CRS.

(1) Operation

• A high-voltage generating device converts the battery voltage into high voltage. The engine ECU sends signals to

terminals B through E of the EDU in accordance with the signals from each sensor. Upon receiving these signals, the

EDU outputs signals to the injectors from terminals K through N. At this time, terminal F outputs the IJf injection

verification signal to the ECU.

External Wiring Diagram

6.4 Sensors

(1) Crankshaft position sensor and camshaft position sensor

• Conventional sensors are used as the crankshaft position sensor and camshaft position sensor. The crankshaft

position sensor is a Magnetic Pick Up (MPU) type sensor, while the camshaft position sensor is a Magnetic

Resistance Element (MRE) type.

Operation Section1–19

(2) Accelerator position sensor and accelerator pedal module

• A conventional hall element type sensor is used as the accelerator position sensor.

Accelerator Position Sensor: DYNA, COASTER

Operation Section1–20

Accelerator Pedal Module: DUTRO

• The MAP sensor is used in the NO4C-TF engine. Sensor output voltage values in relation to absolute pressure are

provided below.

(4) Coolant temperature sensor

• The coolant temperature sensor is used in the NO4C-TF engine. Sensor resistance values in relation to coolant

temperature are provided below.

Operation Section1–22

(5) Mass Air Flow (MAF) meter

• A conventional sensor is used with the NO4C-# engine CRS.

Operation• When a heating element (heating coil) is placed in the air passage, the air absorbs heat and cools the heating

element. For this reason, the resistance value of the heating element decreases, and the current increases. As the

intake air volume increases, the cooling temperature of the heating element also increases. The hot-wire type airflow

meter utilizes the changes in the heating element.

One portion of the intake air passes by the heating element, and the temperature of the heating element resistor

changes in accordance with the intake air volume. The control circuit is used to ensure the temperature of the heating

element resistor is always constant. In other words, since the heating element becomes cooler as the airflow volume

increases, it is necessary to heat the element by increasing current flow through the resistor. This change in current

is converted into voltage by the control circuit IC.

However, even if the intake air volume is constant, the temperature of the heating element resistor changes according

to the intake air temperature. These changes result in errors when detecting the intake air volume. To correct these

errors, an additional intake air temperature compensator resistor (air thermometer) is used.

Operation Section1–23

7. EXHAUST GAS CONTROL SYSTEM (FEBRUARY 2007, AND JUNE 2009)

7.1 Outline

Both an Electric-Exhaust Gas Recirculation (E-EGR) and a Diesel Particulate Filter (DPF) system are used

to comply with Euro 4 emission regulations. The EGR valve, exhaust gas temperature sensor, and

differential pressure sensor are made by DENSO.

7.2 E-EGR System

The E-EGR system is an electronically controlled EGR system. The EGR system reduces NOx by lowering

the combustion temperature through re-circulating a portion of the exhaust gas to the intake manifold. Since

this system may also reduce engine output and decrease drivability, the EGR volume is controlled

electronically to an optimum level in accordance with driving conditions.

Both the electronically controlled EGR system and a high-capacity multipass system EGR cooler are used.

Engine performance has been increased through enabling high-volume exhaust gas recirculation.

A linear solenoid type valve is used as the actuator in the EGR valve. Simultaneous PM and NOx reduction

have been achieved by increasing EGR quantity adjustment precision.

An EGR valve lift sensor is also used. The EGR valve opening is fed back to the engine control computer

to enable optimal EGR control.

(1) Construction and operation

• To improve EGR exhaust gas purification performance, feedback control is performed using the EGR valve position.

Oxygen concentration in the intake air (which changes according to EGR) is controlled to a target value in accordance

with the engine state (engine speed, rising pressure, part temperatures, load and intake air volume.)

• To expand the EGR range, the lift sensor installed on the EGR valve performs feedback control of the

actual EGR quantity in relation to the pre-set target EGR quantity. Feedback control is based on the intake

restriction position and the variable nozzle turbo position.

Operation Section1–24

7.3 DPF System

A conventional DPF system is used with the NO4C-# engine CRS.

Operation Section1–25

(1) Exhaust gas temperature sensor

• A conventional sensor is used as the exhaust gas temperature sensor. Sensor resistance values in relation to exhaust

gas temperature are provided below.

(2) Differential pressure sensor

• A conventional sensor is used as the differential pressure sensor. Sensor output voltage values in relation to exhaust

gas differential pressure are provided below.
