The power unit is the Central Point from which other
mechanical components of the motor vehicle draw their energies. Without the
power unit, the car would simply be useless and inoperable since the driving
torque is generated here.

| Motor Vehicle Engine |
This unit consists majorly of the engine which is known
to be the heart of the motor vehicle.
The engine comes in different forms and sizes. Although
there are two broad categories of engine, the Internal Combustion (I.C.)
Engine, and the External Combustion (E.C.) Engine, the I.C. Engine is widely used
in Automobiles because of its compact nature, flexibility, high efficiency, and
safety concerns.
Common forms of the Internal Combustion Engine include
the Straight In-line Engine, V Engine, W Engine, etc. All these various forms
of I.C. Engine may be different in size and construction, but they are quite
similar in parts and principles of operation.
Generally, the engine works by transferring the rotary
motion of the crankshaft to the pistons through the connecting rods to the pistons.
The Flywheel which is attached to the rear of the crankshaft stores the energy received
from the crankshaft.
The generated torque is then transferred to the
transmission system which shall be considered in our next article.
Quite expository. Thank you Mr. Iboro. But I will be expecting more details on the specific principles of operation of a v-engine, and perhaps, other types of automobile engine.
