    Motorul In 2 Timpi A Decedat?

    SALUTARE TUTUROR! Fiind "putin" pasionat de mecanica si "surubareala" , tot "ma izbesc" in cautarile mele de pe internet "recreative" de REALITATEA URMATOARE: Cat de BUN si performant este motorul in 2 timpi fata de panaramele astea in 4 timpi , complicate si "la jumate" (cand vine vb de lucru mecanic produs) ... nu pot decat sa ma gandesc la O CONSPIRATIE si prostire in masa a oamenilor... Dintotdeauna "ne-a fost varata pe gat POLUAREA" ce o fac motoarele in 2 timpi! DAR : de ce nu zice nimeni nimic de motorul de la APRILIA SR 50?! CARE ESTE IN 2 TIMPI CU INJECTIE DE COMBUSTIBIL? Si care-i cat se poate de curat si eficient ( cu 2 litri faci o suta de km SI AI SI PERFORMANTA!... ) Si acum stiu ce o sa zica MULTI : "Nu sunt la fel de performante "rasnitele" astea in 2 timpi , fata de "rachetele supersport" in 4 timpi , in 4 cilindrii ... " TOTAL gresit : " Other Direct Injection Systems In the early 1990s, an Australian firm, the Orbital Engine Company, developed a two-stroke automobile engine that met then-current U.S. emissions requirements, exceeded the four-stroke fuel efficiency numbers, weighed almost 200 pounds less than a four-stroke that produced similar power, vibrated less than an equivalent four-stroke and cost from $300 to $500 less to manufacture. Snow Goer Needless to say, the transportation industries got excited with Orbital’s demonstration. Ford Motor Company, General Motors, Mercury Marine, Outboard Marine Corporation, Polaris Industries, Bombardier — and likely many other engine manufacturers — soon bought patent licenses to use Orbital’s concepts for clean two-stroke development programs. Automobile companies around the world have launched direct-injection projects, many of which don’t include Orbital’s design. The variety of concepts being developed is impressive and each one seems to confirm the ability to overcome the perceived two-stroke bug-a-boos of suffering from poor economy and high emissions. Mercury Marine uses Orbital technology in its two-stage, direct-injection two-stroke outboards. The Dodge Neon car was originally slated to have a direct-injected, two-stroke engine, but development of the engine was delayed and a small four-stroke went to production. Polaris has license to the Orbital patents and has been working on two-stroke engines that are cleaner than its current Cleanfire semi-direct injection systems. Arctic Cat is committed to two-stroke engine designs for its snowmobiles and it is working on direct injection designs. Yamaha builds two-stroke outboards with High-Pressure Direct Injection (HPDI). The 200 HPDI engine has twin, high-speed fuel pumps that pressurize the gas up to 1,000 psi, and then inject the fuel after the exhaust ports are closed. The system is similar to injection systems on diesel engines. http://www.snowgoer.com/output.cfm?id=1836523 "Coming Soon? KTM Fuel Injected Two Stroke By JohnNicholas • on February 15, 2009 ktm_powervalveIt appears that KTM has Fuel Injection ready for two stroke motocross bikes. In the August 2008 issue of Motocross Digital magazine (free subscription available at ) was the following blurb about the KTM effort. The 250SX could have a bright future, it depends on what happens regarding the rules and regulations: KTM wants them to be introduced to MX2 to allow teams that don’t have millionaire budget to compete against the 4-strokes. For the 2-stroke, the injection is ready, and this would provide cleaner and precise power delivery. While the idea of fuel injection for two-strokes has been talked about and discussed, there has been little to indicate that it would be workable on a racing two-stroke motocross bike. This news points to the fact that KTM has been working on it for quite some time and seems to have solved the issues that prevented fuel injection for racing two-strokes. Since this article in Motocross Digital was written some changes have been announced in the FIM rules to allow two-strokes to compete with four-strokes in MX2 (250cc). There are also rumblings that this rule will be applied to the AMA Outdoor Nationals for 2009. So there is a good chance the Fuel Injected 250SX KTM will be hitting the tracks in the very near future. This is great news for all the two stroke fans of the world. Two thumbs up for the folks at KTM! " http://twostrokemotocross.com/2009/02/coming-soon-ktm-fuel-injected-two-stroke/ http://www.autofieldguide.com/articles/060301.html "Ski-Doo’s E-TEC direct fuel injection technology is perhaps the biggest snowmobile product news for 2009. This technology makes a two-stroke engine burn so cleanly that its emissions ratings are cleaner than some four-strokes, according to Ski-Doo. We don’t doubt those claims. Pull the rope on a Rotax 600 H.O. E-TEC engine (it takes just one, short-and-quick yank to light it) and there’s no smoke or smell at idle, just a steady, low rumble at precisely 1,200 rpm. Squeeze the throttle to engage the clutches and the sled glides away without a puff of exhaust smoke. Ride one all day and your coat will smell fresh when you return to the cabin or truck. " "Compania BRP isi extinde tehnologia E-TEC si la modelele de snowmobile Ski-Doo, prin introducerea motorului Rotax E-TEC 800R. Potrivit producatorului, acest motor in 2 timpi foloseste injectoare electronice sofisticate si un computer central puternic pentru a avea rezultate cat mai performante si eficiente. Motorul debuteaza la modelul in productie limitata Ski Doo MX Z 2010, disponibil numai pe negru. "Acesta nu este un motor de compromis. Nu numai ca genereaza mai multa putere, dar si stabileste noi standarde in materie de consum redus", a declarat Bob Lumley, vice-presedintele Sales & Marketing Ski-Doo/Sea-Doo." De fapt, noul motor E-TEC 800R consuma cu pana la 37% mai putin decat motoarele produse de competitorii nostri". Avantajele motorului 800R E-TEC : • caii putere depasesc PowerT.E.K. 800 • consum redus de combustibil : 12.3 l/100 km • autonomie imbunatatita (325km) • consum redus de ulei(450 km/l) • nu emite fum si nici miros • emisii reduse fata de alte motoare de 800cc " http://www.atvrom.ro/prezinta-noul-motor-rotax-etec-800r-a-425.html MOTOR EVINRUDE V4 60 grade E-TEC "Common Elements Limited Warranty 3 year, non-declining Engine type V4 60 deg E-TEC DI Displacement 105.4 cu in/1727 cc Recommended fuel 87 Octane Emissions compliance Meets Highest Emissions Standards Worldwide Recommended Oil Evinrude/Johnson XD100 Oil Proshaft HP Factory Tunes for High Performance Full Throttle RPM Range 5500 to 6000 RPM Alternator output 133 Amps Total Output/50 Amps Net Dedicated Fuel induction E-TEC DI w/ Stratified low RPM combustion mode Lubrication Multi-point, targeted oiling Bore x Stroke 3.601 x 2.588 in / 91 x 66 mm " http://www.evinrude.com/en-CA/Engines/ETEC_HO/ETEC_115_HO

    Da corect, e 2006. Omologarea era din 2002. Acum am primit si eu traducerea. Da corect, e 2006. Omologarea era din 2002. Acum am primit si eu traducerea. Pot sa iti fac o vizita sa vad ce pozitie este pe ea? Vrea prietena una la fel ca a ta si nu stie inca daca ii e buna.

    "Cred" , Luciane , ca-s DESCOPERITE DE MUUUUUUUUULLLT TIMP unele "chestii interesante"... DAR : problema se pune , CAND ne "arunca" si noua astia muritori de rand CEVA TEHNOLOGIE?! Ca tot se vaita toti de COSTURI ba de cercetare , ba de productie , DAR intre timp tot acei "baieti" ce se vaita de COSTURI MARI , TOT EI INCASEAZA PROFITURI DE NU-TI VINE SA CREZI... E clar si limpede ca lacrima , ca NU SE VREA introducerea de tehnologie noua si eficienta , ci doar MARIREA COSTURILOR SI PROFITURILOR personale ... Poftim , tot japonezii au realizat un motor electric cu randament de 96% (bicicleta are un randament de 98% in conditii de laborator , ADICA LANT PERFECT CURAT SI UNS/lubrifiat cu ulei ... ) Da' cui sa-i zici daca vrei sa introduci scutere electrice?! N-ai cui... CUM sa se renunte la SUV-urile idioate?! NEVER , iti zic eu... OMENIREA , are un viitor sumbru rau de tot ... Unde mai pui , ca mai nou s-a descoperit asa "din intamplare" ca de fapt resursele de petrol SE REFAC LA LOC , dar in timp... adica e ceva de genul : "fa-i plinul Doamne in urmatorii 40-50 ani ... PLEASE..." Au descoperit asta dupa ce au primit "mici stiri" cum ca localnicii din zona puturilor abandonate din cauza nerentabilitatii in exploatare acum 50 ani , AZI , carau petrol crud cu galetile din cauza CA IESEA SINGUR LA SUPRAFATA... ITI VINE SA CREZI?! Macar hai sa recunoastem daca EXISTA CU ADEVARAT UN MOMENT "PEAK OIL" SAU IAR SE PISA ASTIA PE NOI CU BOLTA... (DOAR DE DRAGUL MAXIMIZARII PROFITURILOR...) DEZINFORMARE TOTALA... De fapt , si teoria formarii petrolului e o PROSTEALA NESIMTITA .. AUZI TU , AU CRAPAT DINOZAURII SI PLANTELE SI AU AJUNS ASA FRUMOS LA 3000 METRI SI AU STAT ACOLO SI AU PUTREZIT PANA S-A FACUT TOATA PUTREZICIUNEA PETROL ...AHA... SI MARMOTA INVELEA CIOCOLATA... Pai cum se formeaza petrolul?! CE ESTE PETROLUL?! DE CE SE FORMEAZA NUMAI LA ADANCIMI MARI ?! NU CUMVA SI DIN CAUZA PRESIUNII MARI? Cam ca diamantele asa , care nu-s altceva decat CARBON supus unor presiuni si temperaturi foarte mari... MACAR de ar realiza CAREVA o celula de energie care sa converteasca direct PETROLUL CRUD in energie electrica! SI te rog sa nu-mi zici ca nu se poate pentru ca DEJA EXISTA ASA CEVA , NUMITE FUEL-CELL care folosesc gazul natural pentru a genera energie electrica si apa calda! Si pana si astea au un randament intre 50-80 % in functie de tipul constructiei... Dar cum naiba sa se faca asa ceva?! ei ce p..a mai incaseaza?! unde ar mai fi profiturile de miliarde din petrol?! (PROFITURI FOLOSITE CATEODATA IN INCEPEREA SI MENTINEREA UNOR RAZBOAIE /CONFLICTE IN ZONE "CU INTERES"... ) Uite si motorul acela electric cu randament de 96 % (aproape ca bicicleta naibii... doar ca si muschii omului tot cam 15-25 % randament au... ) " The current green trend of electric vehicles filling up our roads seems to be promising for a cleaner environment in the near future. But many such vehicles still lack the capacity to deliver the speed that gas-guzzling vehicles can do with ease. To overcome such obstacles, researchers in Japan have devised a new brushless high-efficient 100w dc motor. Such an invention helps to convert electric power to motor output at a conversion of 96% efficiency. Another noteworthy aspect is that such a motor can also maintain conversion efficiency in the range from 93% to 96% even as the output changes between 50 watts and 200 watts. However the only hitch is the high cost factor. This will postpone its applications in fields like commercial electric-automobiles as of yet. It will be limited to eco-racing cars only. Once again green technology surfaces but for a price that is beyond common man’s reach. " http://www.greenlaunches.com/gadgets-and-tech/japan-develops-the-most-efficient-electric-motor.php Randamentul unui motor cu benzina e maxim de 25 % ( adica din 10 litri arsi in el , folosesti efectiv doar 2,5 litri...) Diesel-ul e pe la 40% ... P.S. : unde mai pui ca si benzina ce ne-o vand azi la pompa , NU MAI E LA FEL DE BUNA... Ci contine aditivi (oare ce se intampla cu ACESTI ADITIVI PRIN ARDERE?) CARE CRESC CIFRA OCTANICA... ce bataie de joc... SI NOI SUNTEM DE VINA , FIECARE DIN NOI E VINOVAT CA A LASAT MARILE CORPORATII SA AJUNGA PANA AICI! URMATORUL PAS E SA NE FACA SCLAVII LOR ... SI "MENIUL E COMPLET"... http://en.wikipedia.org/wiki/Energy_conversion_efficiency

    LASA-I MAH , ori platesti tu? Daca le zici o data si nu baga la cap , sau macar nu le da de gandit, razi si cu curu de ei , si mergi mai departe... Sau hai , ca un "ultim efort" zi-le de "Walter Kaaden, the chief engineer for MZ motorcycles " http://www.dansmc.com/EXHAUST_2.htm Viitorul e "interesant"! Cu toate ca eu as prefera simplitatea constructiva a motorului electric...
