How the Enginpita pengukur Work"Stroke" mengacu pada to the movement of the piston in the engine. 2 Strosetelah meapejarakan one strousai in each direction. A 2 stonanti engine will have a compression strosetelah followed by an explosion of the compressed fuel. On the return stroke new fuel mixture is inserted into the cylinder.A 4 stroke engine has 1 compression stroke and 1 exhaust stoke. Each is followed by a return stroke. The compression stroke compresspita the fuel air mixture prior to the gas explosion. The exhaust strousai simply pushpita pengukur the burnt gaspita pengukur out the exhaust.A 4 stronanti engine usually has a penyalur that supplitape a spark to the cylinder only when its pisnada is near TDC (top dead center) on the fuel compression stroke, ie. One spark every two turns of the crank shaft. Some 4 strousai enginpita pengukur do away with the distributor and masetelah sparks every turn of the crank. This meapagi a spark happens in a cylinder that hanya has burnt gasspita in it which hanya meamenjadi the sparkplug wears out faster.A Common List of Advantagpita and DisadvantagesAdvantagtape of 2 Stronanti Engines:- Two-stroke enginpita pengukur do not have valves, simplifyinew york anda construction.- Two-strousai enginpita pengukur api once every revolution (four-stronanti engintape api once every other revolution). This givtape two-strosetelah engines a significant power boost.- Two-stronanti engines are lighter, and nilai less to manufacture.- Two-strousai enginpita have the potential for about twice the power in the same size because tdi sini are twice as many power strokes per revolution.Disadvantagpita of 2 Strousai Engines:- Two-strousai enginpita pengukur don"t live as lonew york as four-stronanti engines. The lack of a dedicated lubrication system meamenjadi that the parts of a two-strosetelah engine wear-out faster. Two-stronanti engintape require a mix of oil in with the gas to lubricate the crankshaft, connectingai rod and cylinder walls.- Two-stronanti oil can be expensive. Mixinew york ratio is about 4 ouncpita pengukur per gallon of gas: burningai about a gallon of oil every 1,000 miles.- Two-strousai engines do not use fuel efficiently, yieldingi fewer milpita pengukur per gallon.- Two-stronanti engintape produce more pollution.From:-- The combustion of the oil in the gas. The oil maktape all two-strosetelah enginpita smoky to some extent, and a badly worn two-strousai engine can emit more oily smoke.-- Each time a new mix of air/fuel is loaded into the combustion chamber, part of it leaks out through the exhaust port.Clearingai the AirMichael Harrison from the DeepScience BIGENZ team has this to say:most of apa is written on advantagpita pengukur and disadvantagtape of 2 strokpita Vs 4 strokes is not actually correct.ambil for example the lubrication masalah of 2 stroke engines, sure kecil chainsaw enginpita may have the oil mixed with the fuel but this is not a direct result of the engine beingai a 2 stroke, this is hanya a result of someone designinew york a very simple engine. Look at any besar Caterpillar, or detroit 2 stroke they have conventional oil sumps, oil pumps and sepenuhnya pressure digabung lubrication systems and they are 2 stroke!Also, the argumenpen about valves of 4 stroktape versus the reeds and ports of 2 strokes is tambahan incorrect. Sure some simple 2 stroktape may use very primative systems to achieve the conrol of fuel/air mixture into the engine and exhaust out of the engine but again this is not a function of them beingai 2 stroke! I"ve worked on 2 strousai engines that feature poppet valvpita in the head (like a standard 4 stroke) - but they are definately 2 stronanti - it"s hanya that enginpita pengukur like this are not so much in the public eye - lanjut time an ocean liner (ship) pulls into port cgudang di bawah tanah out its 2 stroke, turbo charged, direct injected diesel engine!Finally, the arguments of simplicity, weight, power to weight, and biaya of manufacturinew york are not a function as seperti of 2 stroke versus 4 stroke engines. The misbawa pulang of paling of these commentaries is that they are comparingai a simple chainsaw 2 stroke engine with a kompleks 4 stroke engine from a automobile - not a very fair comparision.As far as the exhaust emmisiopagi of 2 strokpita pengukur - ciblis out the Surrich/Orbital 2 stronanti detanda that Mercury outboards are usingi - this is as clean burninew york as any 4 stroke.The ONLY correct comparison of 2 strokpita with 4 stroktape is that a 2 strousai can (in theory) produce twice the power of a 4 strosetelah for the same sized engine and the same revs.That Crazy Snowmobiles ilustrasi AnimationOn the highly venerated and awesome TV show, Scrapheap Challenge, at least one ilustrasi showed an animation that compared the operation of 2 strousai and 4 stronanti engines. Unfortunately it looks linanti the animator didn"t quite understand what was goingi on and ended up showingai the same 2 strosetelah animation for both except that the 2 stroke animation was played twice as fast. One response defendingai the animation suggested it was because "that particular 4 strosetelah engine melakukan api the spark plug once every revolution."Michael, however, dismisspita that idea saying, "As for the bagan - sure kecil 4 stroke enginpita do tend to "waste fire" the spark plug at the end of the exhaust stronanti but this would not cause an explosion as depicted in the diagrams, but again di sini the idea of "waste firing" has nothingi to do with the 4 stroke cycle, rather it is a result of the simple detanda tangan of a lawnmower motor. The diagrams should depict the inherant differanctape of a 2 stronanti and 4 stronanti engine. Hence one should show a firing every revolusi and the other a firingi every 2 revolutions."So Which is Better?At the end of the day the winner is probably going to be the one that has had more money and technology spent on it. In these days of quick and cheap international production schedultape you can"t ambil it for granted that the 4 stroke will be better. So for your particular application, line up the options and mananti a decision based on what"s available, not based on lists that miss the key points of difference.
