Reasons for reducing engine power

Behind the power drop in the drive are usually failures of various elements in the injection and ignition systems. It can also be a consequence of a dangerous phenomenon.

In the power supply system included in the injection system, a decrease in engine power will be caused by a malfunction of the fuel pump (due to increased wear), which is not able to provide adequate fuel flow, and hence fuel pressure. A clogged fuel line or clogged fuel filter can also cause this symptom. Other elements in the power system, the failure of which causes the engine to produce less power than it should, are the throttle position sensor and the air mass meter, or, in another way by measuring the load on the drive, air pressure. intake manifold sensor. Incorrect operation of the injectors is also manifested by a decrease in engine power. A similar reaction will occur in the event of a failure of the coolant temperature sensor.

The optimal ignition timing, at which the engine achieves maximum efficiency, is constantly adjusted. Erroneous knock sensor or camshaft position signals mean that the ignition timing calculated by the controller is not correct. Incorrectly installed so-called. static ignition timing will also prevent the engine from developing full power. In systems whose operation is controlled by a control device, its malfunction manifests itself in different ways. Also power reduction in case of motor controller.

If the reduction in power is accompanied by an increase in engine temperature, we are dealing with a very dangerous phenomenon of overheating of the drive unit. The cause must be identified and corrected immediately, as continued use of the engine in this condition may result in serious damage.
