Description

The power of internal combustion engines is determined by the energy that is encased in the fuel and released during combustion. To achieve more or less power, it is necessary, respectively, to supply the engine with more or less fuel. At the same time, for the combustion of fuel, an oxidizing agent - air - is needed. It is the air that is actually sucked in by the engine pistons at the intake strokes. With the "gas" pedal connected to the throttle flaps of the carburetor, the driver can only limit the access of air to the engine or, on the contrary, allow the engine to fill to the limit. The carburetor, in turn, should automatically track the flow of air entering the engine and supply a proportional amount of gasoline.

Thus, the throttle flaps located at the carburetor outlet regulate the amount of the prepared mixture of air and fuel, and hence the engine load. The total load corresponds to the maximum openings of the choke and is characterized by the greatest flow of the combustible mixture into the cylinders. On a "full" throttle, the engine develops the greatest power achievable at a given speed. For passenger cars, the share of full loads in real operation is small - about 10-15%. For trucks, on the contrary, full load modes take up to 50% of the operating time. The opposite of a full load is idling. In the case of a car, this is the operation of the engine with the gearbox disconnected, regardless of what the engine speed is. All intermediate modes (from idle to full loads) fall under the definition of partial loads.
