Detailed Syllable Analysis:

Division Rules Applied:

1. Onset-Coda Division: Separating syllables based on consonant clusters forming onsets and codas.
2. Vowel-Consonant Division: Separating syllables after a vowel sound followed by a consonant sound.
3. Consonant-Vowel-Consonant Division: Separating syllables when a consonant is followed by a vowel and then another consonant.
4. Syllabic Consonant Rule: Recognizing and treating consonants like 'l' as syllable nuclei when they follow a consonant and are not followed by a vowel.

Special Considerations:

The complex consonant clusters in "internal-combustion" require careful application of onset-coda division rules. The syllabic 'l' in "nal" is a notable feature.

Alternative Pronunciations/Regional Variations:

Regional variations in vowel pronunciation (e.g., /ɑː/ vs. /ɔː/ in "com") might occur, but these do not significantly alter the syllable division.
