4.31. Trial start and обкатка the engine after major repairs

At primary start of the engine after end of its regenerative repair near at hand without fail it is necessary to have the class fire extinguisher In!


 PERFORMANCE ORDER

  1. After installation of the power unit on the car, check up levels of impellent oil and cooling liquid in it.
  2. At the turned out candles and temporarily disconnected system of ignition (Check компрессионного pressure in cylinders see), turn the engine, having lifted pressure of oil in it so that there was an operation of a corresponding control lamp on an instrument guard of the car.
  3. Screw spark plugs, connect ВВ wires and restore functioning of system of ignition.
  4. Start the engine. Start can occur to the small delay necessary for lifting of pressure of fuel, however no special complexities should arise.

If claps in the throttle case start to occur, check up installation of a corner of an advancing of ignition and phases timing.

  1. After start it is necessary to warm up the engine to normal working temperature, in the course of a warming up checking it on presence of signs of leaks of oil and cooling liquid. Allow to the engine to work within 15 minutes on single turns that is especially important after replacement шатунных bearings.
  2. Muffle the engine, and once again check up levels of oil and cooling liquid in it.
  3. Now it is possible to start trial runs and обкатке the engine. Deduce the car in area where intensity of traffic is minimum and sharply disperse it till the speed of 50-80 km/h (30—50 miles/ch). Then dump speed to 50 km/h, completely having closed for this purpose throttle заслонку. Repeat procedure of 10-12 times, — arising cyclic loadings will help усадке piston rings in relation to walls of cylinders. Again check up the engine on leaks.
  4. The first 800 km (500 miles) run try to maintain the engine in a sparing mode, regularly and often checking thus engine oil level. The raised expense of oil during the period обкатки the engine is the normal phenomenon.
  5. Approximately through 800—1000 km (500—600 miles) run replace impellent oil and the oil filter.
  6. The following the car can be maintained some hundreds kilometres of run in a normal mode.
  7. Through 3200 km (2000 miles) again replace impellent oil and the oil filter. Now it is possible to consider the engine обкатанным definitively.
