This link to youtube shows a brilliant animation on youtube of the workings of the new internal combustion engine by Scuderi. This engine provides a dramatic increase in fuel efficiency by specialising cylinders and cut harmful gasses by unto 80% my previos article can be found at the link below:

Since this article a working prototype was created which i will review when i find time to research it, but results look promising!

Previous Review:
Scuderi's new Split Cycle Air Hybrid Engine
Scuderi Group in West Springfield, Massachusetts, has recently developed the "Scuderi Split Cycle Air Hybrid Engine" (catchy i know). It is effectively a split-cycle internal combustion engine, but its revolutionary design has modified the common Otto cycle and instead of being only 33% efficient as most engines are, this new system is (in testing) claiming to reach efficiency levels of 40% far and above any other internal combustion engine, and best of all at this level up-to 80% of the toxic and atmosphere damaging gases are not present.
The initial invention was by Carmelo J. Scuderi and apart from the new stroke system, has a range of features to increase power output. One is a hybrid air system which takes energy from braking and stores it compressed air which can be then used in the engine or other areas of the car, to boost efficiency.
So how does it work? The conventional system runs on a four stroke cycle this new system split up this cycle into across two cylinders, one for compression and one for power. The gas is compressed in the compression cylinder and travels through an inlet passage to the power cylinder where it is ignited. The gas passage contains a series of uniquely timed valves which maintain the pressure in the gas throughout all four stages of the cycle, as the power piston moves to top dead centre of its cycle the gas is released into the power cylinder and fired to induce the power stroke. a very good animation of the system can be found here: http://en.wikipedia.org/wiki/File:Scuderi_Split_Cycle_Engine _-_Cycle.gif (or at the top of this post if the animation plays properly!)
By splitting the cycle the Scuderi engine brings a number of advantages to its unique system. The dedicated cylinders can be optimised for the job they are doing as opposed to being multi-tasking like in a normal engine, this boosts their efficiency and it make their engine different to any other around. This means the power stroke is longer and the gases thermal efficiency increases (see the Miller Effect), the compression cylinder can be made wider and as such supercharging the gas in the power piston, increasing power. On top of this the cylinders can be offset at almost any angle to maximize mechanical efficiency and placement within the vehicle.
The key features of it are that:
1. has an exceptionally fast combustion rate
2. a large increase in thermal efficiency
3.a large reduction in NOx emissions (Nitrogen Oxide)
for greater detail there is a breakdown of all the stages and detailed explanations at http://www.scuderigroup.com/technology/theory_of_operation.html
The engine already has 35 issued patents and 60 patents pending in over 50 countries related to the design on the engine, including: Cargine Engineering (Sweden), Gates Corp (Denver), Schaeffler Group (Germany) and the engineering division of Germany's Robert Bosch GmbH.
Overall this engine design is an exciting new development in the world of cars, it could revolutionize the four stroke cycle which has been pretty much unchanged for the best part of 100 yearsPLEASE NOTE: This video is not of my creating, but a brilliant animation. Due to the success of the previous article i'd like to share it with those interested, thoughts would be widely appreciated, if the creator of the video has any issues with my hosting i'd happily remove it from my site

This looks brilliant cant wait to see it in use in production vehicles, havent seen anything like it to rival efficiency in petrol engines, a truely great break through in combustion engine technology
