3. TECHNICAL INFORMATION 3.1. Engines The engines P158LE/ P180LE/ P222LE POLUS Series are V-type liquid-cooled 8/ 10/ 12- cylinder four-stroke Diesel engines with direct injection. 1) Engine block The cylinder block is a single piece of alloy cast iron. To increase its stiffness, it is extended to a level below the crankshaft center line.
Page 18: Engine Lubrication
3.2. Engine Lubrication The engine is equipped with force-feed lubrication. The pressure is produced by a gear pump whose drive gear is in direct mesh with the crankshaft gear at the flywheel end. The oil pump draws the oil from the oil sump and delivers it through the oil cooler and oil filter to the main distributor gallery and from there to the main bearings, big-end bearings and camshaft bearings as well as to the small-end bearings and the rocker arms.
Page 19: Engine Cooling System
The injection pump and the turbocharger are also connected to the engine lubricating system. The cylinder walls and timing gears are splash-lubricated. Each cylinder has an oil jet provided for cooling the underside of the pistons. The lube oil is cleaned in a full-flow oil filter. Depending on the agreed extent of delivery and the design of the engine, the lube oil circuit can be equipped with oil pressure monitors (advance warning and cut-off function) which shut the engine down in the event of a sudden loss of pressure.
Page 20 3.4. Fuel System The fuel is delivered by the fuel lift pump via the fuel filter to the injection pump and from there to the injectors. The fuel is sprayed into the cylinder through nozzles fitted in screw-fit injections in the cylinder heads Excessive fuel delivered and leak fuel from the injectors flow through the return pipe back to the tank.
Page 21 1) Injection pump The in-line injection pump is driven via gears from the crankshaft. It is connected to the force- feed lubricating system of the engine and consequently maintenance-free. The centrifugal governor flange-mounted on the pump casing is a variable range governor designed to keep the speed set by the control lever constant under conditions of varying load.
Page 22 3.6. Intercooler The intercooler is air to air type and has a large cooling fan capacity. The intercooler life and performance depends on the intake air condition greatly. Fouled air pollutes and clogs the air fins of intercooler. As a result of this, the engine output is decreased and engine malfunction is occurred.
Page 23: Air Cleaner
3.8. Air Cleaner Air cleaner is mounted on the engine to purify the air for combustion The intervals at which the air cleaner requires servicing depend on the specific operating conditions encountered. Clogged air filters may cause black smoke and reduce power. A check should be made from time to time to see that the fastening elements securing the air cleaner to the intake manifold seal the connection tightly.
Page 24 Operate the alternator according to To Battery + the instructions given in the chapter Regulator “Commissioning and operation”. RL = 150~250 OHM EA8O3007 2) Starter motor The sliding-gear starter motor is flanged to the rear of the flywheel housing on the left-hand side. As part of every engine overhaul, the starter pinion and ring gear should be cleaned with a brush dipped in fuel and then a coat of grease should be applied again.
Page 25: Commissioning And Operation
4. COMMISSIONING AND OPERATION 4.1. Preparations Before daily starting the engine, check fuel level, coolant level and engine oil level and replenish, if necessary. The notches in the dipstick indicate the highest and lowest permissible oil levels. CAUTION : Do not add so much engine oil that the oil level rises above the max. marking on the dipstick.
Page 26: During Operation
4.3. Running In It is recommended that new or overhauled engines should not be operated at a load higher than about 75% maximum load during the first few hours of operation. Initial run-in should be at varying speeds. After this initial run-in, the engine should be brought up to fuel output gradually.
Page 27: Shutting Down
4.5. Shutting Down Cut off the main circuit breaker of the generator control panel to “stop” After the engine has been running at a high load level, do not shut it down immediately but allow it to idle about 5 minutes so that temperatures may equalize.
Page 28: Maintenance And Care
5. MAINTENANCE AND CARE 5.1. Engine Lubrication 5.1.1. Oil level Check the oil level in the engine sump daily with a dipstick. The level should be between the two notches cut into the dipstick and should never be allowed to drop below the lower notch, CAUTION : Do not add so much engine oil that the oil level rises...
Page 29 • Recommend of lubricating oil Initial factory fill is high quality break-in oil for API Service CH-4 grade. During the break-in period, frequently check the oil level. Somewhat higher oil consumption is normal until piston rings are seated. The oil level should be maintained in the safe range between the Min. and Max.
Page 30 5.1.3. Refilling with oil Refill with fresh engine oil at the oil filler neck. After refilling with oil, rotate the engine with the starter and move the shut-down lever to “stop” at the same time until the oil pressure warning light goes out and the oil pressure gauge shows a pressure.
Page 31 5.1.5. Renewal of filter cartridges • Allow the filter content to run off along drain plugs. Hold a suitable vessel under hole. CAUTION : Oil is hot and under pressure! • After releasing the clamping bolts remove filter bowls. • Renew filter cartridges.
Page 32: Fuel System
5.2. Fuel System 5.2.1. Fuel If Diesel fuel which contains moisture is used the injection system and the cylinder liners / pistons will be damaged. This can be prevented to same extent by filling the tank as soon as the engine is switched off while the fuel tank is still warm (formation of condensation is prevented).
Page 33 5.2.2. Injection pump No alterations must be made to the injection pump. If the lead seal is damaged the warranty on the engine will become null and avoid. • Faults We strongly recommend that any faults developing in the injection pump should be taken care of by authorized specialist personnel.

The excess pressure required in the system will then no longer build up. Premature boiling occurs and coolant is lost. To prevent damage to the engine, open this cap only in exceptional circumstances and fit a new one as soon as possible afterwards.
Page 39 5.5. Turbocharger 5.5.1. Maintenance The turbochargers do not call for any specific maintenance. The only points to be observed are the oil pipes which should be checked at every oil change for leakage and restrictions. The air cleaners should be carefully serviced. Furthermore, a regular check should be kept on charge air and exhaust gas pipes.

Page 123 10.3.1.2. Speed Control Unit for Governor System (DWC-2000 SERIES SPEED CONTROL UNIT) <Introduction> This speed control unit performs the electronic function of the engine governing system. The speed control unit senses the pulses from the magnetic speed sensor, compares them with the speed control unit's set point and supplies the appropriate current output to the actuator to control the engine's fuel system.
Page 124 The engine speed signal is usually obtained from a magnetic speed sensor mounted in close proximity to the teeth of a ferrous ring gear that is driven by the engine. The frequency of the speed sensor signal is proportional to the engine speed. The speed control unit will accept any signal if the frequency is proportional to engine signal, and in the frequency range of the speed control unit (1K to 7.5K Hz.).

Care should be taken to insure that the speed control unit, mount it vertically so that condensation will not accumulate in the speed control unit.
Page 128 • Start engine The speed control unit governed speed setting is factory set at approximately engine idle speed. Crank the engine with DC power applied to the governor system. The actuator will energize to the maximum fuel position until the engine starts. The governor system should control the engine at a low idle speed.

Page 130 • Accessory input The AUXiliary Terminal N accepts input signals from load sharing units, auto synchronizers, and other governor system accessories, DWC accessories are directly connected to this terminal. It is recommended that this connection from accessories be shielded as it is a sensitive input terminal. If the auto synchronizer is used alone, not in conjunction with a load sharing module, a 3M ohm resistor should be connected between Terminals N and P.
Page 131 • OVERSPEED shutdown setting DWC-2000 has a Test switch to determine the OVERSPEED set point and test the engine shutdown function. If you want to adjust the OVERSPEED set point at the speed about 10% higher than the RUN set speed, use the Test switch. When the engine is operating at the Run set speed in pushing the Test switch, rotate the Overspeed Adjust.
Page 132 • Unsatisfactory performance If the governing system functions poorly, perform the following tests. SYMPTOM TEST PROBABLE FAULT Actuator goes to full fuel. then, disconnect speed sensor at Terminals C & D. • Do not crank. Apply If actuator still at full fuel speed control DC power to the unit deffective.
Page 133 • Electromagnetic compatibility (EMC) EMI SUSCEPTIBILITY - The governor system can be adversely affected by large inter- fering signals that are conducted through the cabling or through direct radiation into the control circuits. All DWC-2000 speed control units contain filters and shielding designed to protect the units sensitive circuits from moderate external interfering sources.
