The Six Stroke Engine

The advent of the internal kindleion engine mobilized the world. Since its invention in the early 1800s, cars, trucks, airplanes, even boats now harness the power of combust kindle to travel infinitely faster than ever antecedently thought possible. However the most comm only(prenominal) use railway locomotive type, the four- misfortune, is not without its problems. The four crack locomotive runs hot by nature, and requires a alter system. The added heaviness from a radiator hurts give notice efficiency, and therefore costs more money. The four- snap is as well liable in liberal part for global warming collectible to its high light speed monoxide emissions. These problems seem unavoidable, save novel locomotive engineers have solved them both in the tune of the six stroke engine. Although not save in all day application, there are some(prenominal) different kinds of six-stroke prototypes sporting revealing test results. The most lustrous of these app roach patterns however, appears to be Bruce Crower?s design which uses steam to generate a blink of an eye power stroke. ordinarily after the power stroke in a dominion four-stroke cycles/second the immense agitate from the explosion is dealt with by a radiator. This isn?t only unable because of the additional weight of a cooling system, exclusively since up to 70% of the energy created by the motor is estrus energy, it?s as well counter-productive. Bruce Crower believes the key to a more efficient engine is to harness the wasted heat energy and convert it to particular(a) kinetic energy. His six-stroke design does this by injecting make piddle directly into the cylinder immediately after the exhaust valve closes on the fourth stroke. The water almost instantaneously vaporizes and expands ?up to 1600% its eloquent mass?, slamming the plunger downward for an some other power stroke. On the sixth stroke the rising piston expels the steam, and the cycle repeats. The water is not only used to create a sec! ond power stroke however, just now it also cools the cylinder head, eliminating the eat up for an external cooling system. That means far better fuel economy and a lot less environmentally hurtful exhaust. The use of water for a secondary fuel essentially gives the engine a open gloveed power stroke for either cycle. This means that only fractional the primary fuel (gasoline, diesel, LPS, etc.,) is used to create the same center of kinetic energy as would be used in a normal four-stroke engine. At this point in the engine?s life it uses or so the same amount of water as it does gasoline. The water also apparently does a visionary job of cooling the engine. Mr. Crower has state ?It?ll run for an hour and you bear literally put your hand on it. It?s warm, yeah, but it?s not heat up hot.? Eliminating the use of a radiator also relieves a lot of weight, intend the engine doesn?t need to work as hard. Tests on the single cylinder engine have shown up to a 40% decre ase in primary fuel consumption. The other major benefit of the Crower?s six-stroke engine is reduced emissions. there is dummy up the burnt air-fuel mixture of the first power stroke, but the second only yields steam as exhaust. This six-stroke model has shown in tests to reduce harmful emissions by up to 65%. The steam also seems to do a good job of salmagundi the exhaust system. Crower speculates that steam cleaning the engine every cycle could also do external with the need for a catalytic converter, and further reduce the weight of the vehicle. The Crower six-stroke, being quite new, still has some hurdles to overcome, but early tests have turn out to be very promising. Eliminating excess weight from the cooling system, piece cutting both fuel consumption and emissions is a massive leap in automotive technology. Its ability to use a much higher parting of the total energy created makes the six-stroke the side by side(p) logical place for the auto industry to g o.
