Combustion

sprays fuel directly into the the engines combustion chamber instead of its intake ports (Csaba Csere, April 2010). Additionally, there are engines that make use of variable displacement, which turns off some of the engine cylinders to improve…

Federal standards dictate how much pollution autos may emit, and automakers decide how to achieve the pollution limits. The emission reductions of the 1970's came about because of fundamental improvements in engine design, plus the addition of charcoal canisters to collect hydrocarbon vapors and exhaust gas recirculation valves to reduce nitrogen oxides. The advent of "first generation" catalytic converters in 1975 significantly reduced hydrocarbon and carbon monoxide emissions. The use of…

The Upcoming of Electric Vehicles Nearly 28 percent of the energy consumption within the United States originates from the transportation industry. Personal Vehicles consume more than 60 percent of the energy used for transportation (Source). Due to the rising prices of oil in the US, many Americans have been cautious on their oil consumption. Many people have even resorted to buying smaller, more fuel-efficient vehicles. The Government even offers extra Tax incentives to consumers who…

engines was unique, the things I experienced with job shadowing was unique, and the success and struggle with my project was outstanding. A gas engine is “a type of internal-combustion engine using a flammable gas, such as coal gas or natural gas, as fuel” (Collins English Dictionary). A diesel engine is “an internal-combustion engine that uses the heat of highly compressed air to ignite a spray of fuel introduced after the start of the compression stroke” (Collins…

The 19th century was one of the greatest times of change and innovation in history. Inventions that changed the world sprung up left and right. Almost all significant inventions of this time period are still around today. One of the greatest weapons of war in its time was the ironclad. Ironclads were steam powered warships protected by iron or steel plating. they were first used successfully in the mid 19th century. ironclads were designed for several roles such as: dominating sea battles,…

Light is ON/OFF: Do you know that if the check engine light of your car is on, it indicates the problem in oxygen sensor? The oxygen sensor checks that the fuel injectors gets the gas and air mixture. The fuel injectors then supply the fuel to the combustion process. It helps to increase fuel efficiency. Therefore, if the oxygen sensor is not working properly, the check engine light will be on. It is telling you to repair the oxygen sensor before the emission test. Failing at that, there are…

of the difficulties of using biodiesel in conventional diesel engines are their higher viscosity, acidity levels that influences the structural integrity of the engine and low density which results in low calorific value and leading to incomplete combustion. In this process, in the presence of Sodium hydroxide catalyst and methanol batch transesterfication is applied to sunflower oil for the production of biodiesel. The biodiesel was characterized and then conducted using Nuclear Magnetic…

Engines-petrol and diesel INTRODUCTION:- Petrol Engine: It is an internal combustion engine (known as gasoline engine in North America). It consists of a spark ignition and design to run on petrol and similar volatile fuels. The fuel mixing was done in carburettor in earlier days but now it is done using fuel injection. Petrol engines runs at higher speed than diesel engine, this is due to the small size of piston. Petrol engine has many applications like: 1) Motorcars 2) Motorcycles…

in our lab was the amount of liquid in the containers. If there is too much or too little liquid our measurement will greatly vary. Combustion is a process the relates greatly to what happens in our body. When we consume food it is eventually combined with oxygen to release the energy we need to continue our basic functions. It is important to learn about combustion as it can help us understand more in depth and hard to understand concepts as we go through…
