  • Page 6: Nameplates

    In all your correspondence please always quote engine model, serial number and job number (Order number). Enter 14-digit serial number (is used in the MAN Nutzfahrzeuge Aktiengesellschaft spare parts catalog to distinguish between spare parts). Motor-Nr. / Engine No. NI/II Enter 14-digit engine serial number.
  • Page 7: Safety Regulations

    D Do not touch the engine with bare hands when it is warm from operation – risk of burns. D Exhaust gases are toxic. Comply with the instructions for the installation of MAN Die- sel engines which are to be operated in enclosed spaces. Ensure that there is ad- equate ventilation and air extraction.
  • Page 8 Safety regulations During maintenance and care D Always carry out maintenance work when the engine is switched off. If the engine has to be maintained while it is running, e.g. changing the elements of change-over filters, remember that there is a risk of scalding. Do not get too close to rotating parts. D Change the oil when the engines is warm from operation.
  • Page 9 If faults occur, find the cause immediately and have it eliminated in order to prevent more serious damage. Use only genuine MAN spare parts. MAN will accept no responsibility for damage result- ing from the installation of other parts which are supposedly “just as good”.
  • Page 10 Safety regulations D Comply with instructions for operation of the alternator. See “Commissioning and oper- ation”. D Do not let the raw water pump run dry. If there is a risk of frost, drain the pump when the engine is switched off. Regulations designed to prevent pollution Engine oil and filter elements / cartridges, fuel/fuel filter D Take old oil only to an old oil collection point.
  • Page 11 Safety regulations D After washing apply a fatty skin cream to the skin. D Change oil-soaked clothing and shoes. D Do not put oily rags into your pockets. Ensure that used engine oil is disposed of properly – Engine oil can endanger the water supply – For this reason do not let engine oil get into the ground, waterways, the drains or the sewers.

  • Page 18: Engines

    Technical information Engines The engines D 2866 E / TE / LE / LXE are in-line vertical liquid-cooled 6-cylinder four- stroke Diesel engines with direct injection. D 2866 E is a naturally aspirated engine. D 2866 TE is turbocharged, and D 2866 LE / LXE are turbocharged and intercooled.

  • Page 20: Engine Lubrication

    Technical information 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 21 Technical information 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 cir- cuit 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 22: Fuel System

    Technical information 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 four-hole nozzles fitted in screw-fit injectors in the cylinder heads.
  • Page 23: Turbocharger

    Technical information Fuel filters Before entering the suction chamber of the injection pump, the fuel is cleaned in a two- stage, parallel or changeover filter. Turbocharger (D 2866 TE, LE, LXE) The exhaust gases of the engine are passed through the turbine rotor of the turbochar- ger.
  • Page 24: Intercooler

    Technical information Intercooler (D 2866 LE, LXE) Before entering the cylinders the combustion air compressed in the turbocharger is passed through a heat exchanger (intercooler). Heat removal in the cooler is either by air (air-to-air intercooler) or, in case of the marine application, by means of seawater (air-to-water intercooler) delivered by the raw water pump.
  • Page 25: Electrical Equipment

    Technical information Electrical equipment Alternator The alternator is fitted with integral silicon rectifiers. A transistorized regulator mounted on the alternator limits the alternator voltage. The al- ternator should not be operated except with the regulator and battery connected in circuit to avoid damage to the rectifier and regulator.
