their CR motocrossers, GP bikes and MVX, NS and NSR road bikes. Honda Power Port valve HPP valve . A centrifugal governor opens and closes a 2 blade exhaust valve (using over 50 Parts) Honda V-TACS The "V-TACS" - Variable Torque Amplification Chamber System - works differently from the "AETC system" and it will only work when it is used in conjunction with a tuned muffler. Tuned mufflers/expansion chambers increase power but only at the RPM they are designed for and can actually cause a power loss outside their tuned RPM. "V-TACS system" takes advantage of using an expansion chamber without losing power outside the expansion chamber's tuned RPM. Within the head and cylinder of the engine, there is a chamber that is sealed by a valve. This sealed chamber is vented onto the exhaust port when the valve is open. At low RPM this valve is open, this has the effect of increasing the exhaust manifold volume and negating the power loss that would normally be apparent at low RPM with an expansion chamber. At mid RPM the valve is closed, this enables the expansion chamber to work. It is identified by the head and cylinder, being much larger than normal for its displacement, the cylinder wall is also cast with the wording VTACS on it. V-TACS was a foot-operated power valve system made by Honda on some of its small two-stroke bikes and scooters, like the Honda FC50.

Two-stroke power valve system 99 Honda RC-Valve The Honda Revolution Control valve is designed and works in principle like the "AETC system." A small computer monitors engine RPM and opens and closes a 2 blade exhaust valve controlled by an electric servo. Honda equipped many two-stroke motorcycles such as the NSR125 and NSR250 models with RC - Valve power plants.however this is an electric device and may short out over time Kawasaki KIPS Kawasaki uses a power-valve system called KIPS (Kawasaki Integrated Powervalve System) on their two-stroke bikes. The KIPS utilizes both alterations in port height, closing of the secondary port ducting, and a resonant chamber. KIPS is operated by a mechanical governor. Otto engine Otto Engine Types There are three types of internal combustion engines designed by Nikolaus August Otto and his partner Eugen Langen. They are the 1862 compression engine, which failed, the 1864 atmospheric engine, and the engine known today as the "Gasoline Engine" the Otto Cycle engine created in 1876. Otto engines were used primarily for stationary uses, as Otto had no interest in transportation. Other makers such as Daimler perfected the Otto Engine for transportation use [1] [2] [3] Timeline The 1860 Lenoir Engine Nikolaus August Otto as a young man was a traveling salesman for a grocery concern. In his travels he encountered the internal combustion engine built in Paris by Belgian expatriate Jean Joseph Etienne Lenoir. In 1860 Lenoir succeeded in creating a double-acting engine which ran on illuminating gas at 4% efficiency. The 18 liter Lenoir Engine was able to produce only 2 horsepower. The Lenoir engine ran on the illuminating gas that was made from coal which had been developed in Paris by Philip Lebon.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
