Qhov sib txawv ntawm ob-stroke thiab plaub-stroke outboard motors

1. Quality and structure

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. Ntxiv cov roj av thiab cov roj cav

Cov roj ntawm ob-stroke engine yog sib xyaw ntawm cov roj cav roj. Ob-stroke outboard engine tsis muaj cov roj tshwj xeeb filling chaw nres nkoj, thiab tsis tas yuav tsum ncuav lub cav roj rau lubrication, tab sis nws yog lubricated thaum nws hlawv.

Cov roj ntawm lub tshuab plaub-stroke yog roj av, thiab lub fuselage muaj ib qho tshwj xeeb roj filling qhov. Nws yog ib qho tsim nyog yuav tau ntxiv cov roj kom tsim nyog rau lubricate lub crankshaft thiab lwm yam iav. Tom qab ib lub sij hawm, nws yog tsim nyog los tshem tawm cov khib nyiab roj thiab refill nrog tshiab roj ntawm tib hom los xyuas kom meej lub tshuab' s kev ua tau zoo. kev ua haujlwm siab.

3. Noise and jitter

Vim qhov sib txawv ntawm kev ua haujlwm thiab kev tso pa tawm, lub suab nrov thiab lub suab nrov ntawm ob lub tshuab hluav taws xob ntawm tib hom thiab lub zog horsepower yog me ntsis loj dua li ntawm plaub-stroke outboard.

4. Yooj yim tswj

Vim yog cov qauv yooj yim ntawm ob-stroke outboard lub cev muaj zog, kev saib xyuas thiab kho ntawm ob-stroke outboard motor yog yooj yim dua li plaub-stroke lub cev muaj zog, thiab cov nqi kho kuj tseem qis dua.

5. Fuel use

Ob-stroke tshuab siv cov roj sib xyaw, uas yog, roj av thiab cav roj sib xyaw ua ke, roj av: roj cav=25: 1 thaum lub sijhawm khiav, thiab 50: 1 tom qab lub sijhawm ua haujlwm.

Rau plaub-stroke roj, thov siv roj av saum toj no 92. Cov roj ntxiv rau cov roj tank hauv lub cav sib cais.

6. Roj kev lag luam

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. In terms of price

Plaub-stroke outboards ntawm tib hom thiab tib lub zog horsepower yog kim tshaj plaub-stroke sawv daws yuav.
