The average person today will fill up their vehicles with different grades of petrol, because that is what the common vehicle takes. They normally don’t consider a substitute for the petrol that they fill up their cars with. Although petrol is the most common, it isn’t the only source of power for a car; electricity and diesel can be used instead of the general petrol that powers most automobiles. Although they differ from each other, electricity and diesel are replacements to the average petrol…

Compression Ignition (HCCI) Engine” (First Draft) Abhijit Sonje Ji, C., and Ronney, P. D., 2002, “Modeling of Engine Cyclic Variations by a Thermodynamic Model,” SAE paper 2002-01-2736. Ji and Ronney (2002) developed a Kantor model showing that prior-cycle effects resulting from exhaust gas residuals are a significant factor in cyclic variability of combustion in internal combustion engines. Olsson, J. O., Tunestal, P., and Johansson, B., 2001, “Closed Loop Control of an HCCI Engine,” SAE…

“We’re going green in 10, make sure you have the clutch dumped and stability control off.” , pit radio crackled into Mitty’s helmet. The cars shook on the grid, engines revved up to twenty thousand and fire spitting out of the exhausts. The engines crackled like fireworks, the cars grumbled in the heat as the lights dropped to green. Mitty dumped the clutch and sped off, with full control over his car. He shifted into second, then third, and fourth as he zoomed by other cars. “Seems like the…

Two factors are required for proper operation of a gas turbine. One is expressed by Newton’s third law. The other is the convergent-divergent process. Convergent means approaching nearer together, as the inner walls of a tube that is constricted. Divergent means moving away from each other, as the inner walls of a tube that flares outward. Bernoulli’s principle is used in this process. The venturi of the common automobile carburetor is a common example of Bernoulli’s principle and the…

Parametric study and Optimization of C.I Engine Using Plastic Pyrolysis Oil for low NOx emissions Using Taguchi Method Abstract: Fossil fuel shortage and severe environmental problems have attracted great attention on the exploitation of clean renewable energies. The utilization of lignocellulosic biomass resources will play an increasingly important role in the future. The objective of the study is to optimize the parameters such as plastic pyrolysis oil diesel blend %, injection pressure and…

There are numerous types of car engines which can be categorized depending upon the ignition system, total number of cylinders, block design, camshaft location, strokes per cycle, cooling system and so on. Presently deployed ignition system are spark ignition (gasoline engine) and compression ignition (diesel engine) which use different types of fuel. The required voltage for ignition system is generated from a 12 volt battery (which are generally lead-acid type and a series connection of…

Diesel vs Gasoline “Exploration is the engine that drives innovation. Innovation drives economic growth. So let’s go exploring.” - Edith Widder. Exploring is just what engineers did with the diesel and gasoline engines. They have done wonders for the world and both want the same outcome; power, longevity, fuel economy and reliability,however, they are both different in their own way. The Gasoline and Diesel engine have differences and similarities that an average person might not know. These…

underrated when it comes to a saving money. The business aspect of diesel on how it saves money compared to gasoline engines is that diesel engines are more robust, require less maintenance compared to gasoline engines, and get better fuel economy. The first business aspect of how diesel cars save money is that they require less maintenance than gasoline engines. The reason why diesel engines need less maintenance is because “There is no sparking as the fuel auto-ignites. The absence of spark…

Introduction “The automobile engine will come and then I will consider my life’s work complete” – Rudolf (izquotes, n.d.) Now common place everywhere, automobile engines are small achievement on the list of accomplishments for Rudolf Diesel. The inventions he made helped shape the world we live in today and possible our future. Rudolf Diesel, his name is now synonymous with the invention he made but also engineering itself. Diesel was the first man to patent the diesel engine and the first to…

ugly two-wheeled box with a simple chunk of foam covered by split and cracked black vinyl on top for a seat, two small diameter wheels, and flat tires. Inside the box was an oily chunk of rust my friend had told me was a single-cylinder air-cooled engine with a simple centrifugal clutch and chain drive. For the privilege of buying it right, free, he let me push it…
