Usage Features
The manual outlines several important user instructions and operational guidelines:
- Read Manual: Operators must thoroughly read the manual and adhere to technical operation and maintenance schedules.
- Trial Run: New engines require a 60-hour trial run. Idle or high-speed no-load operation is strictly prohibited during this period.
- Gradual Speed Increase: After starting a cold engine, speed must be increased gradually. Avoid sudden acceleration or prolonged idle speed.
- Coolant Drainage: If ambient temperature might drop below +5°C and no anti-freeze is used, drain water from the radiator and engine.
- Air Filter: Never run the engine without an air filter to prevent unfiltered air from entering cylinders.
- Fuel and Oil: Use specified grades of fuel and oil, filtered through a screen, and stored in clean containers. Fuel should be precipitated for over 72 hours.
- Pre-Start Checks: Before each start, check coolant and oil levels.
- Electronic Parts: Electronic components should only be checked by personnel with electrical knowledge.
- Working Environment: Standard working conditions are defined as Environment Temperature: 298K (25°C), Dry air pressure: 99kpa, and Vapor pressure: 1kpa. Output power should be rectified according to GB/T18297-2001 if conditions deviate.
- Fuel Types: 0# light diesel GB252 for summer, -10# light diesel GB252 for winter. -20# or -35# diesel for temperatures below -20°C or -30°C, respectively.
- Lubricating Oil: CH-4 grade oil is recommended. 15W/40CF-4 for -15°C to +30°C, and 20W/40CF-4 for -10°C to +30°C. Oil level must be between upper and lower marks on the dipstick. Do not check oil level while the engine is running, and do not mix different quality oils.
- Coolant: Ethylene glycol-based antifreeze with anti-rust properties is recommended. For temperatures below 0°C, regularly check antifreeze density. For temperatures above 0°C, anti-rust and anti-scale treated water can be used. Never use untreated water.
- Engine Start: Set power switch and electric key to "start." If the engine doesn't start within 15 seconds, re-start after a 2-minute interval. If it fails after three attempts, stop and troubleshoot.
- Normal Running Conditions: Lubricating oil main pipe pressure: 300 ~ 550kPa (over 80kPa at idle speed). Oil temperature in oil sump <110°C. Coolant exit temperature: 75 ~ 95°C. Exhaust temperature after turbo: ≤600°C. Intake temperature after air intercooled: 55±5°C.
- Winter Operation: Choose appropriate fuel, lubricating oil, and coolant grades based on outdoor temperature. Use an auxiliary starter if necessary. Check battery electrolyte level, viscosity, and unit voltage before the cold season. When stopping the engine in winter, remove the load, run at idle for 5 minutes, and if no antifreeze is used, drain coolant to prevent frost damage.
Maintenance Features
The manual outlines a comprehensive maintenance schedule and troubleshooting guide:
- Periodic Checkup and Maintenance:
- First Check (P): After 30-50 hours of engine run.
- First Grade Maintenance (WD1): Every 200 hours.
- Second Grade Maintenance (WD2): Every 250 hours.
- Third Grade Maintenance (WD3): Every 250 hours.
- Fourth Grade Maintenance (WD4): Every 250 hours.
- Note: These periods are based on 1500 annual running hours. Adjustments are made for fewer (1/2 time) or more (1.5 times) annual hours.
- Maintenance Items:
- Each time oil is changed: Change engine oil, oil filter, check and adjust valve clearance, check nozzle open pressure, change fuel filter, clean fuel pump strainer.
- Every 24 months: Change coolant.
- Regular checks: Water pump, coolant capacity, cooling pipe clamp, intake pipe/hose/flange connections, air cleaner maintenance indicator, air cleaner dust cup, air cleaner main element (clean/change based on indicator/manual), air cleaner safety element (change after 5 main element cleanings), belt tension, turbocharger bearing clearance, fuel pump (in special workshop), idle speed.
- Engine Oil Change Period:
- Normal Conditions: Fuel sulfur content <0.5%.
- Bad Conditions (High Oil Consumption):
- Tropical/frigid climate (>+30°C or <-10°C): 1/2 of normal period.
- Fuel sulfur content 0.5-1.0%: 1/2 of normal period.
- Both bad conditions: 1/4 of normal period.
- Note: Oil used is Grade CF-4.
- Daily Checkup Items: After stopping, check oil and coolant levels, drain water from fuel filter, check charging and oil pressure indicators, check for leaks in oil, water, and air pipe connections, and ensure all fastening parts and instruments are normal.
- Maintenance for Long-Term Storage:
- Clean Up: Clear rust, treat repellent parts (lube oil pipe, fuel system, turbocharger).
- Protective Procedure: After heating, drain oil, clean oil filter, add anti-rust oil to tank/sump. Drain diesel, add 90% diesel + 10% anti-rust oil mixture to protect the fuel system. If no cooling emulsion, drain water, add emulsion and anti-rust oil. Run engine at idle for 15-25 minutes with this mixture. Inject anti-rust oil into intake pipe and combustion chamber by hand-cranking crankshaft. Drain engine oil, remove cylinder head cover, inject anti-rust oil into valve spring and rocker arm. Spread repellent on all processed and rusted parts.
- Storage Measures: Use sealing covers for intake/exhaust pipes, cooling water pipes, and cover the engine with a plastic bag to prevent moisture and impurities.
- Troubleshooting Guide: Provides solutions for common issues like engine not starting (blocked fuel pipes, air in system, pump/injector failure, wrong timing, low cylinder pressure, low temperature), engine stopping after a short time (blocked fuel filter, air in system, lift pump failure, bad fuel, low idle speed), insufficient power (intake blockage, exhaust back pressure, turbocharger issues, air intercooler fault, fuel leaks/quality, FIP/regulator wear, nozzle atomization, valve/fuel timing, regulator speed, high oil level, cylinder head gasket leaks), big fuel consumption (air cleaner, exhaust back pressure, fuel quality/leaks, injector atomization, timing, air leaks, bearing gaps, piston condition, turbocharger pressure/function, intercooler damage), black smoke (intake blockage, exhaust back pressure, fuel quality/supply, injector atomization/pump, turbocharger issues, air intercooler damage), white/blue smoke (bad fuel, low water temperature, timing, nozzle atomization, low compression, piston ring issues, turbocharger seal/thrust bearing wear, fuel return pipe blockage), unsteady speed (poor fuel quality, air in fuel system, governor spring, uneven fuel supply, poor nozzle atomization, turbocharger shakes/damage), low oil pressure (low oil level, main oil passage valve, oil leakage, wrong oil grade, oil pump inlet leaks, high water temperature, oil filter resistance, oil cooler, main oil passage blockage, bearing gaps, worn spare parts), and engine overheating (low water level, blocked radiator, loose water pump belt, damaged water pump gasket/impellers, faulty thermostat, damaged water pipe/air leaks, low oil level).
- Alternator Doesn't Generate Electricity: Troubleshooting steps include checking wire connections, repairing/replacing rotator/stator coil, rectifier tube, insulation, adjusting regulator voltage, and repairing burnt regulator contacts.
- Special Instructions: Do not remove injection pump oil seal. Do not dismantle turbocharger rotor. Injection pump is a precision component. Never loosen or dismantle engine main bearing bolts or connecting rod bolts, as they have strict torque requirements. Connecting rod bolts are one-time use and not reusable.
