3.4.24. Launch of the engine after repair and a running in


After the end of assembly of the engine check the level of oil and cooling liquid twice.

By the turned-out candlelight and the grounded high-voltage wire of the coil of ignition turn a bent shaft until registration of pressure of oil the sensor (if it is provided by a design) or before blackout of a control lamp of pressure of oil.

Screw candles, dress tips of wires and a high-voltage wire of the coil of ignition.

Make sure that the butterfly valve of the carburetor is closed, then start the engine. The engine has to be started immediately, later the short period necessary for filling of the carburetor by gasoline.

Right after launch of the engine it is necessary to set the mode of the raised idling turns to provide the elevated pressure of oil in the lubrication system and bystry warming up of the engine up to the working temperature. In process of a warming up of the engine you watch closely emergence of leaks of oil or cooling liquid.

Switch off ignition and check levels of oil and cooling liquid.

Again start the engine and check installation of the moment of ignition and turns of idling. If necessary adjust.

Make a trip to places with a little heavy traffic, accelerate the car from the speed of 50 km/h to 90 km/h, having pressed a pedal of a butterfly valve before its full opening. Then release a pedal of a butterfly valve, having slowed down the car the engine to the speed of 50 km/h. Repeat the cycle of 10-12 times. At the same time occurs extra earnings of piston rings to walls of cylinders. Double-check levels of oil and cooling liquid.

Make a trip on 1000 km, without subjecting the engine to big loadings (move at a low speed), periodically checking oil level. In the period of a running in the raised oil consumption is possible.

After the run of 1000-1200 km replace oil and an oil filter, tighten bolts of a head of the block of cylinders and check gaps between valves and yokes.

At a run of the subsequent several hundred kilometers conduct the car in the normal mode, avoiding too big and too small loadings.

Later 4000 km of a run replace again oil and an oil filter then the engine is considered passed a running in.
