ini kayaknya perlu diketahui n disikapi

Title: Influence of Ferrocene on Engine and Vehicle Performance
Abstract:
Ferrocene is used as an antiknock additive to replace lead alkyls. To clarify
the influence of one metal additive, ferrocene, on engine, following
experiments were carried out. The insulation resistance of spark plugs was
measured, deposits in the engine were analyzed, and exhaust emission and fuel
economy tests were conducted using gasoline containing ferrocene. The deposit,
which contained iron oxides, adhered to the combustion chamber, spark plugs,
and exhaust pipe when the engine operated with gasoline containing ferrocene.
When vehicles operated with gasoline containing ferrocene, fuel consumption
increased and the exhaust temperature rose. In addition, an abnormal electrical
discharge pattern was observed in spark plugs operating at high temperatures.
Iron-oxide of Fe\d3O\d4 is changed into Fe\d2O\d3 under high temperatures.
Discharge current flows in iron oxides including Fe\d2O\d3 because the
conductivity of Fe\d2O\d3 increases at high temperatures. Therefore, a
defective ignition causes the rise of exhaust temperature because the current
flows to iron oxides, which adhere to the insulation of the spark plug. An
engine bench test was also conducted using gasoline containing ferrocene and a
detergent additive. However, the abnormal electrical discharge did not improve
by detergent additive. These results indicate that ferrocene decreases the
insulation resistance of spark plugs and causes increase in fuel consumption,
exhaust emissions, exhaust gas temperature, and irregular electrical discharge.
yang artinya kira² begini...benerin kalo salah yakk....
Ferrocene dipakai sebagai bahan tambahan antiknock untuk mengganti timbal
alkyls.
Untuk menjelaskan pengaruh satu bahan tambahan logam, ferrocene, di mesin,
dilakukanlah eksperimen-eksperimen berikut.
Resistansi isolasi busi diukur, penumpukkan deposit di mesin dianalisa, dan
emisi gas buangan serta tes ekonomi penggunaan bahan bakar diadakan pada
memakai bensin berisi ferrocene.
Ketika mesin yang menggunakan bensin berisi ferrocene dibedah, terdapat
deposit, yang berisi oksida besi, melekat di ruang pembakaran, busi, dan
knalpot, konsumsi bahan bakar bertambah dan suhu pembuangan naik.
Lagi, pola penyelesaian listrik yang abnormal dilihat di busi yang membedah di
suhu tinggi.
Besi-oksida Fe\d3O\d4 berubah ke Fe\d2O\d3 di bawah suhu tinggi.
Aliran arus di oksida terbuat besi pada Fe\d2O\d3 dikarenakan konduktivitas
Fe\d2O\d3 bertambah di suhu tinggi.
Oleh karena itu, peledakan yang cacat menyebabkan kenaikan suhu karena arus
mengalir ke oksida besi, yang melekat sampai isolasi busi.
Tes-bench juga diadakan pada mesin yang memakai bensin berisi ferrocene dan
bahan tambahan detergen.
Tetapi, penyelesaian listrik yang abnormal tidak bertambah baik di samping
detergen aditif.
Hasil ini menunjukkan bahwa ferrocene mengurangi resistansi isolaso busi dan
sehingga berpengaruh pada bertambahnya konsumsi bahan bakar, emisi gas buang,
suhu gas buang dan aliran listrik yang tidak teratur.
begitu kira² sekilaf info dari ane mengenai Ferrocene...
di wikipedia ada juga kok..
googling aja...baut yang pengen tahu lebih...
