STUDY AND ANALYSIS OF DIFFERENTIAL CONTROLLED CONTINUOUSLY VARIABLE DRIVEJournal For Research
Now a day's development trends in car industry and mobile machines are driven by universal concerns on energy limitations and greenhouse gases reduction, more energy efficient and environmentally friendly vehicles will be needed. As the increasing concerns in the impact of vehicle emissions of carbon dioxides and Nitrogen oxides on the biosphere combined with today's shortage fuel, hence need to find alternate fuel solutions or develop the transmission system in such a way that lower consumption and lower emission should takes place. Continuously variable drive is the type of automatic transmission that allows selection of infinite number of transmission ratios within the finite range i.e. between minimum and maximum value. Continuously variable drive is 34.91% more efficient than that of manual transmission. In order to achieve emission reduction and fuel economy needs to improve fuel efficiency. Continuously variable drive can be improved by coupling differential gear assembly to one of variable speed drives; we can increase the speed variation range at the expense of the horse power range. Numerous combinations of the variables are possible.
Car wheels spin at different speeds, especially when turning. It is known that each wheel travels a different distance through the turn, and that the inside wheels travel a shorter distance than the outside wheels. Since speed is equal to the distance traveled divided by the time it takes to go that distance, the wheels that travel a shorter distance travel at a lower speed. Also note that the front wheels travel a different distance than the rear wheels.
Now a day the most difficult challenges in engine technology is to increase its thermal efficiency, If the efficiency is higher, than there will less fuel consumption and lower atmospheric emissions per unit of work produced by the engine. In Six Stroke engine, the name indicates a cycle of six strokes in which two are useful power strokes. The engine which we get by adding two more stroke in existing four stroke engines generates more power with higher fuel efficiency. The exhausted heat generated form four stroke cycle is used in this engine to get an additional power and exhaust stroke of the piston in the same cylinder. In this engine, steam is produce from water with the help of heat generated from four-stroke cycle, which is later used as a working fluid for the additional power stroke. This steam will force the piston down. As well as extracting power, the additional stroke cools the engine by water which is used for steam generation and removes the need for a cooling system which is used in four stroke Otto cycle and makes the engine lighter and giving 40% increased efficiency over the normal Otto cycle. In six stroke engine. The pistons go up and down six times for each injection of fuel. These six stroke engines have two power strokes: one by fuel, one by steam

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

2. A two-stroke, or two-cycle, engine is a type of
internal combustion engine which completes a power
cycle with two strokes (up and down movements) of
the piston during only one crankshaft revolution.
This is in contrast to a "four-stroke engine", which
requires four strokes of the piston to complete a
power cycle. In a two-stroke engine, the end of the
combustion stroke and the beginning of the
compression stroke happen simultaneously, with the
intake and exhaust (or scavenging) functions
occurring at the same time.
3.
4. The Diesel cycle is a combustion process of a
reciprocating internal combustion engine. In it, fuel is
ignited by heat generated during the compression of
air in the combustion chamber, into which fuel is
then injected. This is in contrast to igniting the fuel-
air mixture with a spark plug as in the Otto cycle
(four-stroke/petrol) engine. Diesel engines are used
in aircraft, automobiles, power generation, diesel-
electric locomotives, and both surface ships and
submarines
5. Diesel engines have the lowest specific fuel
consumption of any large internal combustion engine
employing a single cycle, 0.26 lb/hp·h (0.16 kg/kWh)
for very large marine engines (combined cycle power
plants are more efficient, but employ two engines
rather than one).
Two-stroke diesels with high pressure forced
induction, particularly turbocharging, make up a
large percentage of the very largest diesel engines.

7. The 2-stroke diesel engine is an internal combustion engine with
the five events common to all such engines.
First is intake, when a blower forces air alone into the cylinder.
Compression, squeezing the air into a small volume. This is
when fuel is sprayed into the chamber.
Ignition. Just as with a 4-stroke diesel engine, the heat of the
compressed air ignites the mixture of air and fuel. There is no
spark plug.
Power, forcing the piston down.
Exhaust, removing burned gases.
All in just two strokes. The whole process is a cycle. Everything is
back where it began, ready to run again.
