“…The starter motor fails to spin or draw current due to many possible faults in a DC series motor or because of wiring faults and even the faults with solenoid cannot be ruled out. 13 A weak and defective starter will not engage the starter motor to the flywheel.…”

“…To start the engine, the cranking speed should be around 300 r/min; in other words, the starter motor should run at speeds that the engine will start cranking by itself. 3 All the starters used in vehicles are of direct current operated with the supply voltage of 12 or 24 V. 4 Under the moderate condition, the torque developed by motor vehicles will comprise 20-40 and 30-100 Nm for large commercial vehicles. 5,6 A regular starter motor along with the solenoid will draw up to 150 A under the noload condition and up to 600 A when loaded.…”

A novel design and fabrication of the gear reduction starter motor is proposed. In this proposed configuration, the conventional solenoid of the starter motor is eliminated, resulting in a reduction in the starting current required while cranking, and the weight of starter motor is reduced by making it more compact. Failed/dead cranking and the cost of starter motor are also decreased. The function of the solenoid in the starter motor is replaced with a spring-coupled drive mechanism, which makes the function of the starter motor an automatic process. This replacement will affect the state of charge (SoC) and depth of discharge (DoD) of the battery positively, thereby reducing the battery drain and making it last long.

“…The stochasticity of the loads causes a decrease in the pressure P and the Q feed rate of the lubricant, but this is followed by an instant increase in the temperature T of the TCR body and all its elements. This disadvantage-stochasticity-is eliminated in the practice of mechanical engineering by increasing the power reserve factor and torque [15][16][17], but on the other hand, high power and high torque reduce the efficiency of ICE use due to underloading [18]. Therefore, the problem of the TCR reliability is solved by scientific teams of universities and machine-building plants in other ways: improving the nodes of TCR [6,19]; new structural materials of their parts [1,3]; modernization of the lubrication system and oil supply channels to TCR bearings [2,5]; use of electric pumps [10], control valves and turbo-timers [11,12], various electronic and microprocessor control systems for the operation of the turbo system [17,18].…”

“…Surfacing is a phenomenon of the oscillatory process of the air flow with its essential limitation [7,20,22]. Since in the experimental part of the work it is intended to use a braking device in the form of an air dam, the factory equilibrium modes will be violated [16][17][18]. In this connection, it is required to simulate the operating modes of the damper and to study its characteristics.…”

The priority direction of the development of mechanical engineering is the increase in the energy saturation of the automobile and tractor fleet. One of the most effective ways of boosting modern engines is turbocharging and the use of turbochargers (TCR). However, along with a positive effect-boosting and increasing the power in the range of 5-50%, there is a significant drawback-a decrease in the engine reliability. The main reasons for this are: high stochastic load conditions, which is 10-150%, depending on the type of the work performed. The use of the hydraulic accumulator providing additional lubrication of the TCR rotor bearings predetermines an increase in the rotor run-out time by a factor of 1.5-2.5, and, correspondingly, an improvement in the design parameters of the accumulator. When connecting the brake device, with a simultaneous integrated application of the accumulator, the duration of the run-out of the TCR rotor is reduced by 30-40%. In this case, providing the accumulator with a standard accumulator lubrication of the rotor bearings enables to reduce the volume of the accumulator to 2.0-2.2 L and its dimensions in 1.2-1.5 times. But at the same time, there are surging phenomena of moving with a high-speed air flow. To prevent surging, it is necessary to study the spectrum of eigenfrequencies and the shape of the oscillations of a brake device damper. For this purpose, a classical experimental vibration setup was used and the first five resonance frequencies were determined.
