500			_aResearched regimes of engine operation without load: 1 – test of the original engine; 2 – test with disconnection of four cylinders by stopping the fuel supply; 3 – test with the disconnection of four cylinders by simultaneously stopping the fuel supply and the absence of pumping losses of the cylinder-piston group (CPG) of the disconnected cylinders. It was established that when the crankshaft rotation frequency increases from 1400 min-1 to 2550 min-1 when the fuel supply to half of the cylinders is turned off, the fuel economy changes from 0 to 0.53 kg/h. When the fuel is turned off and there are no CPG pumping losses, the fuel economy changes from 1.2 kg/h to 3.88 kg/h. Recommendations have been developed that allow to increase the efficiency of wheeled vehicles by 11-26% by disconnecting a part of the cylinders.
