Exhaust Has Excessive Black Smoke
- Sistem udara masuk atau buang
- Sensor tekanan atmosfer
- File flash
- Kualitas bahan bakar
- Penyetelan katup
Tindakan yang Direkomendasikan
- Periksa apakah sistem udara masuk mengalami penyumbatan dan/atau kebocoran.
- Periksa apakah filter udara mengalami penyumbatan.
- Lakukan inspeksi visual pada sistem, apakah ada penyumbatan dan/atau kebocoran di perpipaan udara masuk.
- Pastikan turbocharger berfungsi dengan baik.
- Periksa apakah sistem buang mengalami penyumbatan.
- Perbaiki kebocoran yang ditemukan. Hilangkan penyumbatan yang ditemukan. Ganti komponen rusak yang ditemukan.
- Lepaskan sensor.
- Bersihkan sensor dari serpihan, kelembapan, atau es.
- Pasang sensor.
- Periksa Caterpillar Electronic Technician (ET), apakah ada kode diagnostik aktif di sensor. Jika tidak ada kode diagnostik aktif, sensor dapat digunakan. Pembacaan yang benar untuk tekanan atmosfer adalah antara
50 kPa (7,25 psi) dan100 kPa (14,5 psi) .
Verifikasikan bahwa file flash versi terbaru telah diinstal. Rujuk ke Pemecahan Masalah, "Perangkat Lunak ECM - Penginstalan" untuk mendapatkan informasi.
Cuaca dingin akan mempengaruhi karakteristik bahan bakar secara negatif. Rujuk ke Buku Petunjuk Pengoperasian dan Perawatan untuk informasi tentang meningkatkan karakteristik bahan bakar selama pengoperasian dalam cuaca dingin.
Periksa penyetelan katup. Rujuk ke Pengoperasian Sistem/Pengujian dan Penyetelan untuk informasi yang terkait dengan penyetelan katup.
