The Six Stroke Engine

The advent of the internal lose ones temperion railway locomotive 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 previously thought possible. However the most comm only(prenominal) employ 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 provoke efficiency, and so costs more money. The four- snap is as well amenable in liberal part for global warming receivable to its high light speed monoxide emissions. These problems seem unavoidable, save recent locomotive engineers have solved them both in the mastermind of the six stroke engine. Although not save in all day application, there are some(prenominal) different kinds of six-stroke prototypes sporting baronial test results. The most lustrous of these creations however, appears to be Bruce Crower?s design which uses steamer to generate a hour power stroke. usually after the power stroke in a average four-stroke musical rhythm 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 fire up energy, it?s in any case 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 pee 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 quiet mass?, slamming the plunger downward for an early(a) power stroke. On the sixth stroke the rising piston expels the steam, and the cycle repeats. The w ater is not only used to create a second pow! er stroke however, only it also cools the cylinder head, eliminating the take in for an external cooling system. That means far better fuel economy and a lot less environmentally prejudicial exhaust. The use of water for a secondary fuel essentially gives the engine a open rolled power stroke for all(prenominal) 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 tell ?It?ll run for an hour and you bear literally put your hand on it. It?s warm, yeah, but it?s not sear hot.? Eliminating the use of a radiator also relieves a lot of weight, kernel the engine doesn?t need to work as hard.

Tests on the single cylinder engine have shown up to a 40% decrease in primary fuel consumption. The other major benefit of the Crower?s six-stroke engine is reduced emissions. in that respect is noneffervescent 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 modify 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 ha s some hurdles to overcome, but early tests have tur! n up to be very promising. Eliminating excess weight from the cooling system, dapple cutting both fuel consumption and emissions is a vast leap in automotive technology. Its ability to use a much higher parting of the total energy created makes the six-stroke the adjacent logical place for the auto industry to go.
