Gambar di atas menunjukan aliran di sepanjang fuel system. Fuel transfer pump mengalirkan fuel dari tank ke fuel filter, fuel filter akan membersihkan fuel sebelum fuel tersebut memasuki main pump. Main pump terdiri enam buah fuel pump. Masing-masing individu fuel pump selanjutnya akan memasok fuel bertekanan tinggi ke fuel injection nozzle melalui high pressure fuel […]

AIR INDUCTION AND EXHAUST SYSTEM 320D
Udara mengalir melalui air filter kering type canister sebelum tiba di turbocharger. Filter udara berada di belakang pintu akses bagian sebelah kiri dari engine. Kotoran yang menyumbat elemen filter dapat menurunkan unjuk kerja dari engine. Air filter indicator (tanda panah) akan memberi tahu apabila air filter membutuhkan perawatan. Apabila diperlukan penggantian dari air filter maka […]

HEUI system components (2)
The engine coolant temperature sensor (1) is located in the front of the right cylinder head. This sensor is used with the ECM to control various functions. The following systems or circuits use the temperature sensor output to the ECM: The Caterpillar Monitoring System Coolant Temperature Gauge over the CAT Data Link The High Coolant […]
HEUI system components (1)
The atmospheric pressure sensor (1) is installed on the hydraulic supply pump group adapter and is vented to the atmosphere. A foam block below the sensor helps prevent the entry of dirt into the sensor. The sensor performs the following functions: Ambient pressure measurement for automatic altitude compensation and automatic air filter compensation. Absolute pressure […]
HEUI Hydraulic pump components
The pump control valve (1), also referred to as the “injection actuation pressure control valve,” controls the angle of the pump swashplate which varies the pump oil flow. Also mounted on the hydraulic supply pump group is the hydraulic temperature sensor (2). This sensor is used by the ECM for viscosity compensation to maintain consistent […]
HEUI system components
The principal component in the HEUI system, the Electronic Control Module (ECM, 1), is mounted on top of the right front valve cover. The ECM is the “heart” of the engine. The ECM performs engine governing, timing and fuel limiting. It also reads sensors and transmits data to the instrument display system through the CAT […]
3408E/3412E HEUI FUEL SYSTEM
The electronic components in the HEUI fuel system are very similar to those used in other EUI systems. However, in the HEUI system, the injectors are not actuated by a camshaft. A high pressure hydraulic pump, which draws oil from the pressure side of the lubrication pump, raises the pressure to a maximum of 22800 […]
HEUI fuel system components
The water separator (1), which also functions as a primary fuel filter, is an important part of the fuel system. As with any high pressure fuel system with operating pressures at approximately 150000 kPa (22000 psi), fuel quality is important. Water in the fuel can cause corrosion of the plungers and barrels. Dirt can cause […]
3408E Engine D9R
The HEUI system has many features and benefits not possible with mechanical fuel systems. These features include a very clean exhaust, improved fuel consumption and cold starting, simplified maintenance with fewer moving parts, and reduced operating costs. The HEUI system eliminates many of the mechanical components of a “pump and line” system. It also provides […]
