Mesin Mobil, Bensin atau Diesel, yang memilih, analisis komparatif

Selama beberapa dekade, "perang" adalah "perang" antara mesin diesel dan bensin, untuk membantah keberadaan yang tidak ada artinya. Saat ini, banyak pembuat mobil melengkapi model-model yang sama dari pembangkit listrik diesel dan bensin, oleh karena itu tidak mungkin untuk mengatakan bahwa jenis jenis motor yang sama lebih disukai. Sejak pendapat spesialis tidak setuju, dalam artikel ini kita akan melihat semua kelebihan dan kekurangan mesin bensin dan diesel, yang akan membantu memahami mana yang lebih baik untuk dipilih.

Selain itu, unit daya diklasifikasikan oleh lokasi dan jumlah silinder, berdasarkan jenis bahan bakar, dalam hal jumlah operasi mesin, sesuai dengan metode pembentukan campuran bahan bakar, dan sebagainya. Namun, mesin diesel dan bensin adalah yang paling umum.

Konsumsi bahan bakar mobil diesel dan bensin, analisis komparatif

Konsumsi bahan bakar spesifik adalah indikator efisiensi yang menentukan berapa banyak bahan bakar yang dikonsumsi oleh motor dengan kekuatan 1 kW dalam satu jam. Konsumsi bahan bakar spesifik lebih tinggi untuk mesin bensin. Untuk mesin diesel, itu adalah 200-230 gram, untuk bensin - 265-305 gram.

Selain itu, diesel injeksi bahan bakar segera terjadi ke dalam ruang pembakaran, masing-masing, kerugiannya minimal. Di mesin bensin, udara dicampur dengan bahan bakar di manifold intake.

Torsi diesel dan otomatis pada bensin

Motor bensin disingkat, bukan diesel, menghasilkan torsi yang lebih kecil. Jika Anda memerlukan daya tarik yang sangat baik dan Anda sering mengangkut beban besar, lebih baik memberikan preferensi pada diesel - ia memiliki torsi yang jauh lebih tinggi, yang diimplementasikan secara penuh karena tingkat kompresi yang tinggi untuk penyalaan diri diesel. bahan bakar.

Kekuatan maksimum, yang memiliki lebih tinggi

Meskipun unit daya bensin memiliki torsi yang lebih kecil, mereka mampu menghasilkan daya tinggi dan bersantai dengan revolusi besar, karena mereka memiliki dinamika akselerasi yang sangat baik. Menggabungkan dengan mereka untuk parameter ini hanya bisa hanya mesin diesel modern dengan turbocharging.

Keandalan, Analisis Komparatif

Mesin diesel dianggap lebih dapat diandalkan daripada bensin, yang disebabkan oleh kekhasan desainnya, yang melibatkan penurunan suhu pembakaran, stabilitas bahan bakar dan pekerjaan pada revolusi kecil. Namun, beberapa mesin dibedakan oleh kehidupan layanan yang relatif rendah - terutama ini menyangkut kendaraan dari beberapa tahun terakhir pembebasan, di mana mesin diesel memiliki sejumlah besar peralatan elektronik dan tingkat pemaksaan yang tinggi. Namun terlepas dari ini, pembangkit listrik klasik membuktikan daya tahan yang sangat baik dari mesin diesel.

Perbaikan, di mana lebih dan lebih sulit

Meskipun, dengan operasi yang tepat, mesin diesel mengenakan lebih sedikit bensin dan lebih tahan lama, dalam praktiknya sangat sering. Selain itu, perbaikan mesin diesel lebih mahal, karena kompleksitas desain dan biaya besar suku cadang. Sebagai aturan, suku cadang untuk mesin bensin jauh lebih kecil, dan seorang spesialis yang akan untuk pekerjaan ini, untuk menemukan lebih mudah.

Harga pembelian, yang lebih mahal, dan mengapa

Dalam mesin diesel, rasio kompresi jauh lebih tinggi, sehingga kepala blok, crankshaft, rods, blok silinder, piston, dan sebagainya mengalami beban yang lebih tinggi, yang mengakibatkan yang sesuai harus diperkuat. Akibatnya, biaya mesin diesel kalah dengan analog bensin.

Biaya layanan, apa bedanya

Di Rusia, sebagai aturan, masalah dengan mesin diesel muncul karena penggunaan bahan bakar berkualitas buruk. Minyak dan filter harus banyak diubah. Juga, masalah dapat terjadi selama perbaikan, karena mesin diesel adalah desain yang kompleks. Mobil pada bensin ke tingkat yang lebih rendah bereaksi terhadap kualitas bahan bakar. Kekuatan dan pergantian motor cukup tinggi, dan suku cadang untuk perbaikan lebih mudah diakses.

Periode Pemeliharaan

Tidak seperti mesin bensin, frekuensi pemeliharaan diesel secara signifikan kurang. Dengan demikian, penggantian minyak motor dan filter oli di diesel harus dilakukan setiap 7,5 ribu kilometer jarak tempuh, di mesin bensin - setiap 10 ribu kilometer.

Daya tahan mobil diesel dan bensin

Motor bensin beroperasi pada revolusi yang lebih tinggi daripada diesel. Kisaran kerja unit daya diesel biasanya terbatas pada 5000-6000 rpm, ketika bensin berputar ke 8000-9000 revolusi per menit. Diesel lebih tahan lama, tetapi hanya di bawah kondisi operasi yang tepat.

Sebagai aturan, mesin bensin pergi untuk merombak hanya tiga ratus ribu kilometer ketika beberapa mesin diesel dapat berlalu tanpa intervensi serius yang sudah mencapai satu juta kilometer.

Bagaimana menemukan mekanik yang baik untuk mempertahankan diesel

Seperti yang telah disebutkan di atas, sebagai akibat dari kompleksitas desain unit diesel, menemukan autoslemer yang baik tidak begitu sederhana. Hubungi hanya bengkel mobil yang diuji untuk spesialis berkualifikasi tinggi untuk menghindari masalah di masa depan.

Bahan bakar musim dingin berkualitas baik, mengapa penting untuk diesel

Di unit diesel, sistem bahan bakar sangat sensitif, sehingga perlu menggunakan bahan bakar berkualitas tinggi. Jika bahan bakar berkualitas rendah akan jatuh ke dalam sistem, itu langsung terjadi pada kristal parafin, yang tersumbat oleh filter dan pipa bahan bakar, sebagai akibat dari mana kendaraan akan berjalan saat bepergian.

Kecepatan Mobil Diesel dan Bensin

Kecepatan manuver di dalam mobil dengan mesin diesel jauh lebih besar daripada mobil dengan unit daya bensin. Ini dijelaskan oleh fakta bahwa diesel berada di atas torsi dan dicapai pada REV rendah. Berkat ini, pengemudi tidak memiliki ketidaknyamanan saat bermanuver dalam arloji jalan.

Pemanasan pada waktu yang dingin, yang memiliki lebih lama

Mungkin, semua orang tahu tentang masalah unit diesel dalam cuaca dingin. Di diesel, bahan bakar proposal mandiri menggunakan pemanasan udara selama kompresi. Pada suhu kurang dari tiga puluh derajat Celcius, udara tidak dapat menghangatkan suhu operasi untuk menyalakan bahan bakar. Untuk menghindari masalah ini, lilin panas digunakan di dieselle, yang memanaskan ruang bakar sebelum mulai suhu yang diinginkan.

Dengan mesin bensin di musim dingin, ini dikecualikan. Bahan bakar stabil mudah terbakar dari percikan, yang menyediakan awal yang mudah. Pengemudi hanya harus memilih minyak motor yang tepat dan mengikuti biaya baterai.

Knalpot toksisitas, yang lebih buruk

Karena indikator pembakaran bahan bakar dan efisiensi mesin diesel lebih tinggi, ada lebih sedikit knalpot berbahaya daripada bensin.
