Driving the engine crankshaft with an electric and pneumatic starter

The engine resistance torque does not have a constant value. This is due to the occurrence of gas forces (charge exchange in the cylinders) and masses moving in a reciprocating motion. The driving of an internal combustion engine crankshaft by an electric and pneumatic starting system has been characterized. The features of the process resulting from changes in the engine resistance torque and the properties of the energy source – the starting system – have been indicated. The degree of non-uniformity of the crankshaft rotational speed of an engine driven by these systems has been compared. The results of tests on driving the engine crankshaft by an electric starting system and a comparative analysis of driving the engine crankshaft have been presented. Changes in the power characteristics and operating parameters of the electric and pneumatic starter under the influence of temperature changes have been discussed.Starting a reciprocating internal combustion engine consists of its transition from a state of rest to a state of performing functional tasks – generating torque on (…)
