Revolutionary 5th Generation Two-Stroke Engine Technology


Smarter Engine Design

<p>The CITS engine technology provides the basis for a lighter, smaller, smoother, lower cost, petrol (or LPG) engine per kW, whilst eliminating the usual mixing of oil with the petrol for lubricating a two-stroke, and the associated pollution from exhaust emissions of that burnt oil.<br> <br> <b>Green Engine Technology:</b><br> <br> In the growing field of Plug-in Hybrid Electric Vehicle (PHEV) technology of today and tomorrow, the CITS engine can run at its sweet spot rpm, super-efficiently tuned and emissions-controlled, and take advantage of its ultra-low friction and inertia. This feature also applies to the huge market for portable industrial power units, such as generators and water pumps.</p> <p> <img border="0" src="" width="443" height="378" style="border-style: solid;border-width: 1px"></p>


CTIS Engine Technology

<ul> <li>It is a patented two-stroke petrol engine, like no other before, patented in 20 countries.</li> <li>It does not consume its lubricating oil like normal two-strokes, but recirculates it.</li> <li>It allows the lowest inherent imbalance forces (vibration) of any V-twin four or two-stroke.</li> <li>It eliminates the costly roller bearings and their complex fitment to multi-cylinder crankshafts, found at the bottom of two-stroke engines.</li> <li>The technology has an independent appraisal from an internationally recognised expert, and for it the inventor has been awarded an SAE nomination for “excellence in automotive Engineering”.</li> <li>It retains the high power-to-weight and low cost-to-power ratios of the two-stroke.</li> <li>It eliminates the expense, weight, friction and maintenance of the valves, springs, camshaft and drive, found in the top of four-stroke engines.</li> <li>With just two cylinders, as a smooth V-twin, from 250 to 1250 ccs, it can deliver from 30 to 140 kW – as much as a typical 4-cylinder four-stroke – at under half the cost.</li> <li>Constant rpm applications, such as in plug-in hybrid electric autos and portable generators, allows super-tuning for its lowest emissions, maximum torque and best economy.</li> <li>It uses established factory methods and machinery to manufacture.</li> </ul>

For his engine technology, Basil van Rooyen was awarded an SAE-A “Automotive Engineering Excellence Awards 2012” in September 2012. The citation read :
“In recognition of excellence embodied in the nomination of ‘Cits engine technology’ and its benefit to the Australian Automotive Industry and Community”

Also for the recreational, outboard and motor-cycle NTS engine markets, the CITS’s reduced carbon emissions and shorter crankshaft length provide significant cost, weight and balance benefits for manufacturers.
