1.0. What is ontology? Basically, the term of ontology is derives from Greek and “onto” meaning and “logos” interpreted as “science”, that’s mean ontology can be understood as a science or study of being. The word can be divided into two senses such as exist an entity thing. Other than that this word is about what to be or to exist. According to Nicola (2009)” the word ontology can be used with different meaning in different communication. John Sowa (1998) study found that subject of ontology is
DIRT BIKES There are two basic types of motorcycles. One type is made for riding on smooth surfaces like roads or paved race tracks. These motorcycles are called road bikes. They are heavier, faster, and more powerful than off-road bikes. Off-road motorcycles, or dirt bikes, are lighter than road bikes. Dirt bikes are built to handle rough terrain like dirt, mud, and rocks. Not all people use dirt bikes for sport. Some people need their dirt bikes for work. “Members of the Royal Canadian
it was called super bowl motocross but then came the term and the start of supercross. In supercross these were tight cornering tracks with big jumps rhythm sections, and woops sections. The bikes that were first ever ran on these tracks were 2 stroke meaning they are high rpm bikes which of the time were the fastest bikes around of this time but there were a lot of issues with the bike which I will explain. Supercross has changed over time the bikes the tracks and the pace of the race. To start
Whether zipping along a winding trail, flying through the open flats, or powering up a steep hill snowmachines and the rider need to use physics to stay in control of the machine and themselves. The main compenents are the track, engine, skis and riding. Snowmachine tracks are essential to making a snowmachine move. Ever since snowmachines first originated in the late 50's designers have been finding ways to improve traction in a variety of conditions. Some of these conditions are driving on groomed
most common are the two stroke engine and the four stroke engine (A stroke is one movement of the piston Microsoft Encarta 96 Internal Combustion Engine). The general principle of the two-stroke engine is to shorten the periods in which fuel is put into the combustion chamber and in which the spent gases are exhausted to a small fraction of the duration of a stroke instead of allowing each of these operations to occupy a full stroke. In the simplest type of two-stroke engine, the poppet valves are
From four stroke engines to gas turbine engines, the Otto Company to Rolls Royce, engines and propulsion systems have changed the world we live in for almost one hundred and fifty years. With each passing year, something new arrives; something more complex yet more advanced in the terms of propulsion systems. Even though these systems may seem to¬¬¬ change every year and may seem more complex, the principle behind the structure has remained virtually, the same since the first internal combustion
From the mid-1800s to today, the internal combustion engine is becoming more and more complex. From minor improvements, to total reconstruction; the internal combustion engine has changed greatly, and is still changing. By the 3000s, who knows what possibilities will await, but for one to understand the evolution of the internal combustion engine, they must be knowledgeable of the history, present, and future. What is internal combustion? Internal combustion is the process of internally burning gasoline

With this engine we had to dismantle it recording all the steps taken to pull it down. After the engine had been taken apart, all the functions of the engine had to be observed and
23 October 2017 Diesel Engines Diesel engines are a marvel of the world and have been since creation in 1892. Today there are several types of these engines including, two-stroke and four-stroke engines as well as the idea of how diesel engines operate. The diesel engine is a necessary component of the shipping industry as well as the daily lives of people. Diesel engines are an important component of society in how they are used efficiently and effectively. Diesel engines have been around since
Car engines have been here for about two centuries. The earliest invented engine was the steam engine. Over the time period man has improved the development of the engine. From 1885 to present day the engines have a place in physics when it comes to how it works, how it is made, how there is a variety of engines, and how it has impacted our transportation. When it comes to how a car engine works the ordinary gasoline car engine turns gasoline into a moving transportation in motion making a car move
of a Diesel Engine The world we live in is surrounded by diesel engines. They are on the freeways, railways, airways, and are one of the leading electricity producers in the world. They are also becoming more popular in automobiles. These engines are efficient and reliable and they are getting very sophisticated. However, the physics behind these engines has not changed. By way of definition, courtesy of Diesel Engine Engineering: [a] diesel engine is an internal combustion engine in which the
Combustion Engines Introduction Internal Combustion Engine, a heat engine in which the fuel is burned ( that is, united with oxygen ) within the confining space of the engine itself. This burning process releases large amounts of energy, which are transformed into work through the mechanism of the engine. This type of engine different from the steam engine, which process with an external combustion engine that fuel burned apart from the engine. The principal types of internal combustion engine are :
The internal combustion engine operates on the basic principle as its name implies, internal combustion engines have four-stroke four basic steps that repeat with every two revolutions of the engine: (1) Intake stroke / exhaustion (2) The compression stroke (3) Power / expansion stroke and (4) Exhaust stroke 1 intake stroke: The first stroke internal combustion engine is also known as the suction stroke because the piston moves to the maximum volume position (downward direction in the cylinder)
SIX-STROKE ENGINE Introduction The six-stroke engine is an ingenious invention that has the potential to increase engine efficiency by around 30 percent. As fossil fuels are increasingly more expensive to produce and utilize, many have been seeking for answers to these problems. The six-stroke engine seeks to solve some of these problems by exploiting heat that would normally be lost in the four-stroke engine. It does this by utilizing an extra pump to produce more torque and power. In the following
A heat engine is a machine, which converts heat energy into mechanical energy. The combustion of fuel such as coal, petrol, diesel generates heat. This heat is supplied to a working substance at high temperature. By the expansion of this substance in suitable machines, heat energy is converted into useful work. Heat engines can be further divided into two types: (i) External combustion and (ii) Internal combustion. In a steam engine the combustion of fuel takes place outside the engine and the steam
internal combustion engine is a heat engine that converts chemical energy in a fuel into mechanical energy, usually available on a rotating output shaft. 2.Chemical fuel energy is first converted into thermal energy by means of combustion or oxidation air into the engine. The heat energy raises the temperature and pressure of the gases within the engine, and the high pressure gas is expanded against motor mechanical devices. This IsConverted by mechanical linkages to a rotating engine crankshaft expansion
Learning how a vehicle works can be very helpful to learn to get to see how everything comes together and makes a vehicle run properly. There are a few main components that allow a vehicle to run properly such as the engine, cooling system, drive train, brakes, electrical system and the exhaust. It’s very important that all of these components work properly for the vehicle to run efficiently. Without one of these components the vehicle may not run at all or it will run but will not be able to stop

We can offer case in point regarding isochoric process in the event that many of us warmth or even great the actual contents of your covered package
Internal combustion engines gain repelling force by high pressure, which composed of combustion of the fuel in the combustion chamber. Depending on this repelling force ,piston starts to move and it supplies the engine power to the required mechanical elements so, runs the vehicle. This is the working principle of internal combustion engines. In other words, internal combustion engines are the machines, which turn fuel’s chemical energy before turning mechanical energy. Combustion occurs inside
