The Great Debate: Two Stroke vs. Four Den store debat: totakts vs fire

The battle for supremacy between two stroke and four stroke quads is likely to rage on forever, except for outside factors that may end this age old debate; it is very likely that upcoming legislation could end production of two stroke engines, making it impossible to get a new two stroke quad. Kampen om overherredømme mellem totakts-og firetakts quads er sandsynligt, at vreden i det uendelige, med undtagelse af uvedkommende faktorer, der kan ende på denne ældgamle debat, det er meget sandsynligt, at kommende lovgivning vil kunne ende produktion af totaktsmotorer, der gør det umuligt at få en ny totakts quad. So if you’ve ever considered getting a two stroke quad, the clock is ticking. Så hvis du nogensinde har anset for at få en totakts quad, for tiden løber.

Mechanically the difference between a two stroke and four stroke lies in how often the spark plugs fire. Mekanisk forskellen mellem en totakts-og firetakts ligger i, hvor ofte de tændrør brand. In a two stroke, it fires once with every revolution of the cam, while a four stroke only fires the plugs every other revolution of the cam. I en totakts, det brande gang med hver omdrejning af knast, mens en fire takts kun brande den stik hver anden revolution af cam. With everything being equal, a two stroke will have twice as many combustions as a four stroke, which causes it to produce much more energy with the same size engine. Med alt lige vil en totakts vil have dobbelt så mange combustions som en fire-takts, der forårsager det til at producere meget mere energi med samme størrelse motor. While this may make a two stroke sound like an obvious choice, there are several drawbacks to the design and performance characteristics of two stroke ATV engines. Selvom det kan gøre en totakts lyde som et oplagt valg, der er flere ulemper til udformning og ydeevne, totakts ATV motorer.

The extra energy and heat produced by a two stroke requires oil to be added to the gas to keep the engine properly lubricated. Den ekstra energi og varme, der produceres af en totakts kræver olie, der skal føjes til gas for at holde motoren korrekt smurt. Because oil is put in the combustion chamber, two stroke engines smoke a lot, which is the reason for the imminent ban on them. Fordi olien er puttet i forbrændingskammer, to taktsmotorer røg en masse, som er årsagen til den forestående forbud mod dem. One side effect of the impressive power that two stroke engines produce is that the top end of the engine must be rebuilt somewhat frequently, depending on how hard the engine is pushed. En bivirkning af den imponerende effekt, at to taktsmotorer producere er, at den øvre ende af motorens skal genopbygges temmelig ofte, afhængigt af hvor hårdt motoren er skubbet. Although the rebuild is not terribly expensive, it must be done periodically to avoid rebuilding the entire engine. Selv om rebuild er ikke frygteligt dyrt, det skal gøres med jævne mellemrum for at undgå at genopbygge hele motoren.

For many riders the constant maintenance is worth the performance they get out of their two stroke engine, but the accessibility of this power may be prohibitive for some riders, riding styles, and terrain. For mange ryttere den konstante vedligeholdelse er værd at udføre de får ud af deres to takts motor, men tilgængeligheden af denne magt kan være uoverkommelige for nogle ryttere, rider stilarter, og terræn. In order to tap into the power of a two stroke engine, you have to keep the throttle close to wide open to stay in the power band. For at udnytte kraften i en totaktsmotor, er du nødt til at holde gaspedalen tæt på vid gab for at opholde sig i effektområde. Although some models are better than others, some stock two strokes lack real power on the low or midrange. Selv om nogle modeller er bedre end andre, nogle bestand to slagtilfælde manglende reel effekt på den lave eller mellemtoneenheder. In the hands of an experienced rider, a two stroke is an amazing machine, but in certain scenarios, you can lose all your power by making a necessary up shift or slowing down without a hard down shift. I hænderne på en erfaren rytter, en totakts er en fantastisk maskine, men i visse scenarier, du kan tabe al din magt ved at gøre en nødvendig op skift eller nedbremsning uden et hårdt ned overflytning. However, their explosive power makes two strokes the engine of choice for many racers, especially in racing disciplines that require frequent jumps and quick acceleration out of turns, such as Motocross. Men deres eksplosive magt gør to slagtilfælde motoren valg for mange racers, især i væddeløb discipliner, der kræver hyppige hopper og hurtig acceleration ud af vending, såsom Motocross.

As far as typically maintenance, most four stroke quads require relatively little attention. Så vidt typisk vedligeholdelse, mest firetakt quads kræve relativt lidt opmærksomhed. Spark plugs and oil changes are always necessary, but you do not need to rebuild the engine on a regular basis. Tændrør og olie ændringer er altid nødvendigt, men du behøver ikke at genopbygge motoren på regelmæssig basis. However, many riders complain of the high cost of rebuilding four stroke engines when necessary, but a four stroke engine should hold up longer than a two stroke if it is rode properly. Men mange ryttere klager over de høje omkostninger ved at genopbygge fire taktsmotorer, når det er nødvendigt, men en fire takts motor skal holde op længere end en totakts, hvis det er red korrekt. If you keep a four stroke high in the rpm range all the time, you are asking for trouble. Hvis du holder en fire slag højt oppe i omdrejninger i minuttet spektrum hele tiden, du beder om problemer. Although four strokes do not possess the characteristic break - away acceleration of a two stroke engine, they have access to power through a larger rpm range, which eliminates the need to have the throttle wide open all the time. Selv om fire slagtilfælde ikke er i besiddelse af de karakteristiske pause - væk acceleration af en totakts motor, de har adgang til magten ved et større omdrejninger i minuttet spektrum, der eliminerer behovet for at have gasspjældet helt åbent hele tiden. Access to power in the low and midrange allows for a much more leisurely riding experience, or the ability to dive into deep mud and come out the other side. Adgang til magten i lav-og mellemtoneenheder giver mulighed for en langt mere afslappet ridning erfaring, eller evnen til at dykke ned i dybt mudder og kommer ud den anden side. Because a four stroke has power on the low end, it has a much easier time freeing itself from deep mud, while a two stroke is usually doomed if it comes to a stop in mud. Fordi en fire slagtilfælde har effekt på den lave ende, det har en meget nemmere tid at frigøre sig fra dyb mudder, mens en totakts normalt er dømt, hvis det drejer sig om et stop i mudder. Four strokes, in many cases, have a higher top speed than two strokes, but will take much longer to get to their top speed. Fire streger i mange tilfælde har en højere tophastighed end to slagtilfælde, men det vil tage meget længere tid at komme til deres tophastighed. Four strokes have improved a lot over the years, with some many dominant racing quads being propelled by four stroke engines. Fire streger er blevet forbedret meget i årenes løb, med nogle mange dominerende væddeløb quads blive fremdrevet af fire taktsmotorer. However, the Honda 250R, a classic two - stroke quad, is still taking podium spots over ten years after it began production. Men den Honda 250R, en klassisk to - slagtilfælde Quad, er stadig under podiet spots over ti år, efter at det begyndte produktionen.

For the most part, two stroke engines are better suited for light sport quads and four strokes, which produce most of their power on the low end, are more suited for heavier quads made for mud, rocks, and work applications. For de flestes vedkommende, totakts motorer er bedre egnet til lette sport quads og fire streger, der producerer de fleste af deres magt på den lave ende, er mere egnet til tungere quads gjort for mudder, klipper, og arbejde ansøgninger. The debate between two stroke and four stroke engines is not likely to end soon, but production of two stroke engines may. Debatten mellem totakts-og firetakts motorer sandsynligvis ikke vil ende snart, men produktionen af to taktsmotorer maj. If you prefer high speed, airborne, adrenaline heavy riding and you don’t mind spending some time turning a wrench, you may want to get your hand on a two stroke quad while you still can. Hvis du foretrækker høj hastighed, luftbåren, adrenalin tunge ridning, og du har ikke noget imod brugte nogen tid på at dreje en svensknøgle, kan du få din hånd på en totakts quad mens du stadig kan.
