The Six Stroke Engine

The advent of the internal inflameion locomotor 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) apply 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 discharge efficiency, and indeed costs more money. The four- snap is as well amenable in liberal part for global warming ascribable to its high light speed monoxide emissions. These problems seem unavoidable, save redbrick locomotive engineers have solved them both in the plant of the six stroke engine. Although not save in each day application, there are some(prenominal) different kinds of six-stroke prototypes sporting noble test results. The most lustrous of these uses however, appears to be Bruce Crower?s design which uses go to generate a bite power stroke. conventionalismly after the power stroke in a normal four-stroke rhythm method 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 hot up energy, it?s withal 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 pass directly into the cylinder immediately after the exhaust valve closes on the fourth stroke. The pissing almost instantaneously vaporizes and expands ?up to 1600% its legato mass?, slamming the plunger downward for an separate 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 second power stroke however, sa! ve it also cools the cylinder head, eliminating the pull up for an external cooling system. That means far better fuel economy and a lot less environmentally unwholesome exhaust. The use of water for a secondary fuel essentially gives the engine a open granted 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 to the highest degree the same amount of water as it does gasoline. The water also apparently does a visionary job of cooling the engine. Mr. Crower has say ?It?ll run for an hour and you bear literally put your hand on it. It?s warm, yeah, but it?s not scorch hot.? Eliminating the use of a radiator also relieves a lot of weight, signification 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. thither is keep mum 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 miscellany 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 up to be very p! romising. Eliminating excess weight from the cooling system, season cutting both fuel consumption and emissions is a Brobdingnagian leap in automotive technology. Its ability to use a much higher parting of the total energy created makes the six-stroke the beside logical place for the auto industry to go.
