The reciprocating piston petrol engine
Published in M.J. Nunney, Light and Heavy Vehicle Technology, 2007
It thus follows that one complete cycle of operations occupies two complete revolutions of the engine crankshaft. Since energy is necessarily required to perform the initial induction and compression strokes of the engine piston before firing occurs, an electrical starter motor is used for preliminary cranking of the engine. Once the engine is running the energy required for performing subsequent induction, compression and exhaust strokes is derived from the crankshaft and flywheel system, by virtue of its kinetic energy of rotation. Kinetic energy is a term used to express the energy possessed by a body due to its mass and motion. The principle of an engine fly-wheel is therefore to act as a storage reservoir for rotational kinetic energy, so that it absorbs energy upon being speeded up, and delivers it when slowed down.
Overview and introduction

The electrical system covers many aspects such as lighting, wipers and instrumentation. A key component is the alternator (Fig. 1.18) which, driven by the engine, produces electricity to run the electrical systems and charge the battery. A starter motor takes energy from the battery to crank over and start the engine. Electrical components are controlled by a range of switches. Electronic systems use sensors to sense conditions and actuators to control a variety of things – in fact, on modern vehicles, almost everything.

The automotive electrical system has been modelled in MATLAB 2018 Simulink. The starter motor provides the cranking torque for automobile operation while the starting signal to the motor is provided through the battery via the ignition lock. Once the vehicle engine starts rotating, the alternator, connected to the automobile engine (as evident from Figure 1), recharges the battery and also provides electrical energy to the other onboard accessories like the lighting system, music system, etc. The heat transfer block models heat transfers in a thermal network. The rate of heat transfer is proportional to the temperature difference, heat transfer coefficient, and surface area in contact with system operation.
