Motor Engine
A motor engine is a machine that generates mechanical force as well as motion from another form of energy.  Also referred to as prime mover, it is the power plant that propels the motor. Initially the term motor was utilized to distinguish latest internal combustion-powered engines from former vehicles powered with a steam engine. However, it can be utilized to refer any engine which produces motion. Nowadays, the term is utilized for describing the devices that carry out mechanical work. In general work is provided by exerting linear force or torque. It is utilized to operate other machinery which is capable to produce pump water, compress gas or electricity.

The car motor engine works on the principle of internal combustion engine. They operate on a four-stroke Otto cycle. Since its evolution they have gained great popularity and ar/e the most successful for automobiles whereas diesel motor engines are utilized for buses and trucks. Karl Benz was one of those having great interest in developing new engines. He started to work on new designs in 1878. He made great efforts for developing a reliable gas two-stroke engine which was very powerful. It was based on the design of four-stroke engine made by Nikolaus Otto. In earlier days, motor engine development created a much wider array of engines as compared to common used nowadays.

Engines have cylinder designs ranging from 1 to 16 along with relevant variations in overall weight, size, cylinder bores, and piston displacement. Majority of models were having four cylinders and power ratings from 14 to 90 kW (19 to 120 hp). Numerous two-stroke-cycle three cylinder models were developed whilst the majority of engines had in-line or straight cylinders. In addition to this, there were various V-type models as well as horizontally opposed four and two-cylinder models even.  Moreover, overhead camshafts were frequently utilized. The smaller motor engines were generally located and air-cooled at the rear of the vehicle. Also compression ratios were comparatively low. In 1970s and '80s there was an increased interest in increased fuel economy.

There are various kinds of motor engines like diesel motor engines, rotary engine, two stroke engines and gas turbine engines. Each one of the above has its own advantages and disadvantages. In earlier days, external combustion engine were utilized in old steam engine trains. Internal combustion takes less fuel. That is why it is more efficient as compared to external combustion. Furthermore, an internal combustion engine has comparatively smaller size with an equivalent external combustion engine. This is why cars are not using steam engine.


Car motor engine comprises several parts. The main part of the car motor engine is the cylinder along with the piston that moves up and down in the cylinder. Usually, car motor engine incorporates more than one cylinder. A variation of engine configuration can affect the efficiency, manufacturing cost, smoothness and several other attributes of your automobile.
