The Six Stroke Engine

The advent of the internal lardion locomotive 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 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 burn down efficiency, and therefrom costs more money. The four- snap is as well responsible for(p) in liberal part for global warming delinquent to its high light speed monoxide emissions. These problems seem unavoidable, save innovational locomotive engineers have solved them both in the coordinate of the six stroke engine. Although not save in both day application, there are some(prenominal) different kinds of six-stroke prototypes sporting arresting test result s. The most lustrous of these formulates however, appears to be Bruce Crower?s design which uses move to generate a arcminute power stroke. linguistic rulely after the power stroke in a normal four-stroke wheel around 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 commove energy, it?s overly 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 peeing directly into the cylinder immediately after the exhaust valve closes on the fourth stroke. The wet almost instantaneously vaporizes and expands ?up to 1600% its liquified 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 u! sed to create a second power stroke however, besides it also cools the cylinder head, eliminating the trace for an external cooling system. That means far better fuel economy and a lot less environmentally detrimental exhaust. The use of water for a secondary fuel fundamentally gives the engine a open payed power stroke for both 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 well-nigh the same amount of water as it does gasoline. The water also apparently does a visionary job of cooling the engine. Mr. Crower has declared ?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, marrow 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. on that point is windlessness 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 multifariousness 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, s till has some hurdles to overcome, but early tests ha! ve proven to be very promising. Eliminating excess weight from the cooling system, plot of land cutting both fuel consumption and emissions is a extensive 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.
