This is a guest post from my friend Kiran. He is passionate about bikes and all other types of machines. He has recently started blogging at Strictly My Space.
No worries, You’ll get to know who these guys are by the time you finish reading this.
How many of us haven’t driven a car or rode a two-wheeled motorcycle or at least traveled in it? Given the audience that I expect on my page, I am sure the answer is none! And thus definitely all of us have heard about the thing called “engine” which is what gets us moving. I have my doubts that everyone knows this part though! Anyways not deviating from the topic, most of us (exclude mechs) would not have an idea that it’s the work and efforts of Nikolaus August Otto circa 1867 that has helped mankind to burn and pollute the green world and then dream of reinventing the green world once again. My literary skills apart, Otto was the German Inventor who made Internal combustion (IC) engines (All of the engines that run our cars and motorbikes and any other fuel driven piece of equipment these days) possible. Otto Cycle (It’s not a bicycle, a thermodynamic cycle) is the theoretical gas cycle based on which IC engines were developed over the past century.
The said thermodynamic cycle had its share of inefficiencies right from its invention and inventors over the century have attempted and succeeded to curb the inefficiencies by a long way. A quick no-nonsense comparison would be Ford Model T, the mass production revolutionizer which had a 2.9 liter (Yes!) engine giving out 20 BHP peak power compared to 2012 Ford Ranger 2.3L putting out 143 BHP at peak. All of these improvements have been results of great engineering feats including findings from 2 World Wars and commendable inputs from the racing fraternity. Though there have been lots of developments to curb the inefficiencies, the basic engine design remained the same through 130 years except for few of the inventions which never made it into the mass production arena. Wankel rotary engine is a notable one among those.
American Inventor Carmelo Joseph Scuderi (alas! He doesn’t even have a Wiki Page), who spent all his life inventing and improving new technologies finally dedicated his efforts to improve the IC engine which hasn’t undergone a major change over more than a century. Through a span of 3 years from 1998 to 2001, Scuderi finalized his improved design of the internal combustion engine based on Miller cycle. Scuderi passed away in 2002, and his lineage of engineers is carrying forward his invention, which definitely seems to be one of the most radical developments in this front.
Though most of us won’t know the differences, The Scuderis and highlighting 80-85% reduction in NOX emissions as one of their key selling points, which definitely is a claim worth looking out in the quest to rebuild the greenery that we lost to the industrial revolution. Engines will still continue to have pistons and cylinders, a few more pipes and connections more here and there and all cylinders won’t be firing!
Enough of blabber from me, I hope I’ve done justice to my opening statement and all of you got to know who those “guys” were and what they did. Do spare a thought, at least for Mr. Otto when you start your engine next time or hear the all so familiar growl on the road.
Will Scuderi and Miller push Otto to the distant past in History and just be a part of the theory? As usual Time will have the last say.
