The Energy Input ( Qin )

In 2002 a joint project between International Navistar and the Ford Motor Company was born. “The goal of this project was to create an engine that was fuel efficient, emission compliant and would be able to outperform all of the competition” (Banks Power). With over 2 million ford super duty’s equipped with the 7.3l Powerstroke engine on the road, the new engine would have big shoes to fill. The engine that was to replace the outdated, underpowered and overall inadequate 7.3l Powerstroke was the International Navistar 6.0l turbo diesel.

Firstly: the source of fuel is impossible to exist. The water in a water car would not ignite no matter how much energy is passed through it. There is an option around this however (i will touch upon this more further in the document)

We need to get some use out of this other wise wasted energy. What we really want is more power, and for this unfortunately the engine needs to burn more fuel. The turbine fed by the exhaust gases connects to a compressor that compresses intake air into the engine, which builds up pressure in the intake manifold. Now when the intake valve opens, the compressed air is forced into the combustion chamber. This allows more air to fill the chamber. We will need more fuel to match the amount of air in the combustion chamber. On computerized cars, computers take care of this accordingly. What you get is a more explosive force from combustion, and more compression, about 60 percent better

After many years of trial and error, a combination of inventors and engineers developed a practical, effective internal combustion engine that greatly affected the world. This paper will give opposing views on the background and analyze the effects it had on transportation and the environment.

A period of 5 years from 2008 to 2013 is considered for combustion instabilities performance evaluation before modifications measures are fully implemented. In the past major changes in the gas turbine exhaust gas temperature distribution as well as reduced margin to the combustion stability were observed in all 5 S1 gas turbines, leading to hot/cold spots events and trips, Acceleration Max 1,Max 2 unload events and Max 3 trips.

In the operating conditions T1-IRI8, the average fuel consumption of diesel and CNG buses is decreased by 6.5% than in the operating conditions T1-IRI2. In these operating conditions, flow/capacity ratio is higher. This is indicated by bigger difference between average design and operating speeds (about 12km/h).

All internal combustion engines rely on the combustion of a chemical fuel. This process normally outcomes in the production of a large quantity of

Environmental concerns have been raised from time to time because of the dependency on the gasoline-fueled engine as the chief auto powertrain technology. This has resulted in exposing many automobile users to unpredictable prices of fuel. These issues were, however, the reason for

A car fueled by a typical gasoline engine runs differently than an electric. Instead of having a battery to power the engine, the car uses an internal combustion unit to propel the car. The gasoline that the owner adds to the vehicle is heated by the combustion unit and is mixed with oxygen to power the engine. When the driver pushes the pedal down, that activates the combustion unit.

Methanol as a biofuel is an environmental friendly substitute to pure diesel and can be obtained from biomasses. Use of biofuels such as methanol for combustion process is associated with positive environmental impacts. Using pure methanol or blended with diesel fuel in automotive has been proposed by researchers. In this paper, methanol was injected into combustion chamber of a ISM 370 HD diesel engine and exhaust emissions of this engine which took advantage of pure methanol were evaluated by using AVL FIRE CFD code software at four engine speeds (1200, 1400, 1600 and 1800 rpm). Additionally, influences of EGR mass fraction and various injection timings were investigated. For validation of simulation, in-cylinder mean pressure and rate of

In today’s motorized life , It’s difficult to live without motor (Engines) and the main source of it’s input power is fossil fuels & partly electric power. In future these fuels or electricity may not be available widely as they are non renewable energies. So, it may be difficult to use engine with the fuels.

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.

The main issue with the internal combustion engine was its energy transfer efficiency. A large portion of the engines energy was lost through heat and kinetic energy through the exhaust, Alfred Büchi was obsessed with the idea it could be changed. A naturally aspirated engine, also known as N/A, is the engine most cars on the market today have. It relies on the intake stroke of the engine to pull the necessary air into the cylinders and use it for the combustion. The turbo charger is in simpler words a compressor, which uses exhaust fume energy to drive a shaft supplying power to the compressor. The

That covers the basic function of an engine fron intake to exhaust. Next we will explore the relationship of Horsepower vs Torque.

The training project entitled “To study the petrol (VVT engines) and diesel (DDIS engines)” aims to study the different types of engines used and manufactured by Maruti Suzuki. It also studies the various types of problems occurred in the engines in running conditions. This project is a thorough study of the VVT & DDIS engines, their usefulness, their efficiency and their high performance due to their new technology. It also includes the case studies of the cars which were reported to the workshop having engine related problems.
