The difference between two-stroke and four-stroke outboard motors

1. Cáilíocht agus struchtúr

In terms of machine workmanship, the structure of the two-stroke machine is simpler and saves a lot of parts than the four-stroke machine. That is to say, the four-stroke machine is heavier than the two-stroke outboard machine, and the two-stroke machine is more convenient to carry.

2. Gásailín agus ola innill a chur leis

Is meascán d'ola inneall gásailín é breosla an innill dhá-stróc. Níl calafort líonadh ola speisialta ag an inneall lasmuigh dhá-stróc, agus ní gá ola inneall a dhoirteadh le haghaidh lubrication, ach tá sé lubricated nuair a dhóitear é.

The fuel of the four-stroke machine is gasoline, and the fuselage has a special oil filling hole. It is necessary to add a proper amount of oil to lubricate the crankshaft and other gears. After a period of time, it is necessary to remove the waste oil and refill with new oil of the same type to ensure the machine's performance. high performance.

3. Torann agus Giodam

Mar gheall ar an difríocht i modhanna oibre agus sceite, tá torann agus Giodam an innill dhá-stróc den bhranda céanna agus horsepower beagán níos mó ná an torann agus an t-aschlár ceithre bhuille.

4. Éasca le cothabháil

Mar gheall ar struchtúr simplí an mhótair lasmuigh dhá-stróc, tá cothabháil agus deisiú an mhótair lasmuigh dhá-stróc níos áisiúla ná an mótar ceithre stróc, agus tá an costas deisiúcháin níos ísle freisin.

5. Úsáid breosla

Úsáideann meaisíní dhá bhuille breosla measctha, is é sin, déantar gásailín agus ola innill a mheascadh i gcomhréir, gásailín: ola innill=25:1 le linn na tréimhse reatha, agus 50:1 tar éis na tréimhse reatha.

Le haghaidh breosla ceithre stróc, bain úsáid as gásailín os cionn 92. Cuirtear an ola leis an umar ola san inneall ar leithligh.

6. Geilleagar breosla

If the outboard machine is used for work or operation, or for a long time every day, the four-stroke machine with the same horsepower will save about 30% fuel than the two-stroke machine. That is to say, the more four-stroke machine is driven, the more fuel efficient. And from the perspective of environmental pollution, the two-stroke structure is simple. Insufficient fuel combustion results in a higher residual degree of exhaust gas, which is not conducive to the current environmental protection.

7. I dtéarmaí praghais

Tá outboards ceithre bhuille den bhranda céanna agus an capallchumhacht céanna níos daoire ná cinn ceithre bhuille.
