Kruse - Limited Temperature Cycle
The Kruse Limited Temperature Cycle is an improvement on the Otto and Diesel Cycle processes. By controlling (limiting) peak combustion temperatures in direct injection gasoline (petrol) and diesel engines, the Limited Temperature Cycle allows compression ratios to be increased with appreciable gains in volumetric efficiency for spark-ignition engines and lowers peak temperatures to significantly reduce the creation of Nitrogen Oxides (NOx) in exhaust gas emissions in compression-ignition engines.
Environment and Economics
It would appear that one of the many challenges facing automotive manufacturers is:
"The production of conventionally powered automobiles and trucks that meet the needs of their customers, while evolving towards high-economy, eco-friendly (zero emission) platforms that will meet the needs of their customers in the years to come."
Understandably, there are several points of view regarding the timescales involved in reaching universal zero emission modes of transport, such as that offered by the hydrogen fuel-cell. However, the likely reality is that these are still several decades away from mass production and will need significant investment in terms of distribution infrastructure to make them a viable alternative to fossil and alternative fuels, even in metro areas.
In the meantime, manufacturers are faced with the business of building affordable vehicles with the performance that their customers need, while incrementally reducing emissions and improving fuel economy. This is where the Kruse Limited Temperature Cycle will be of benefit.
Wide Application of Use
The Kruse Limited Temperature Cycle may be used in all forms of direct injection, spark-ignition and compression-ignition engines and is completely independent of fuel type. It is therefore effective for engines using liquid fuels, such as; gasoline (petrol), diesel, methanol and bio-fuels, as well as gaseous fuels, such as; compressed natural gas (CNG), liquefied petroleum gas (LPG) and hydrogen.
The Limited Temperature Cycle provides benefits to the following groups:
There are a number of immediate benefits to be derived from the implementation of the Kruse LTC:
Implementation leads to a number of secondary benefits:
Although it's expected that benefits will be applicable across the spectrum of applications, some fuel types will realise more particular benefits than others:
It is hoped that by the time you have reviewed the material on this web site you will have an understanding of the Kruse Limited Temperature Cycle and will appreciate that its application will make the achievement of better fuel economy and less pollution a near-term reality.
