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

1. Sifati va tuzilishi

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. Addition of gasoline and engine oil

Ikki zarbali dvigatelning yoqilg'isi benzinli dvigatel moyining aralashmasidir. Ikki zarbali tashqi dvigatelda maxsus yog 'to'ldirish porti yo'q va moylash uchun dvigatel moyini quyishning hojati yo'q, lekin u yoqilganda moylanadi.

To'rt zarbli mashinaning yoqilg'isi benzin bo'lib, fyuzelajda maxsus moy to'ldirish teshigi mavjud. Krank mili va boshqa viteslarni moylash uchun tegishli miqdorda moy qo'shish kerak. Ma'lum vaqtdan so'ng,'mashinaning ishlashini ta'minlash uchun chiqindi yog'ni olib tashlash va bir xil turdagi yangi moy bilan to'ldirish kerak. yuqori ishlash.

3. Shovqin va jitter

Ishlash va egzoz usullaridagi farq tufayli bir xil tovar va ot kuchining ikki zarbali dvigatelining shovqini va jitteri to'rt taktli tashqi dvigateldan biroz kattaroqdir.

4. Xizmat qilish oson

Due to the simple structure of the two-stroke outboard motor, the maintenance and repair of the two-stroke outboard motor is more convenient than the four-stroke motor, and the repair cost is also lower.

5. Yoqilg'idan foydalanish

Ikki zarbli mashinalar aralash yoqilg'idan foydalanadi, ya'ni benzin va dvigatel moyi mutanosib ravishda aralashtiriladi, benzin: dvigatel moyi=ishlayotgan davrda 25: 1 va ishga tushirish davridan keyin 50: 1.

To'rt taktli yoqilg'i uchun, iltimos, 92 dan yuqori benzindan foydalaning. Yog 'dvigateldagi moy idishiga alohida qo'shiladi.

6. Yoqilg'i tejamkorligi

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. Narx jihatidan

Four-stroke outboards of the same brand and same horsepower are more expensive than four-stroke ones.
