Motor diesel adalah motor dengan pe

Motor diesel adalah motor dengan pembakaran dalam yang pada proses pembakarannya dipicu oleh kompresi pada suhu yang tinggi di dalam silinder. Perbandingan kompresi yang rendah mengakibatkan performance yang dihasilkan motor diesel tidak maksimal, bahkan menyebabkan knocking. Mendasarkan pada sistem termodinamika untuk siklus tekanan konstan maupun siklus sabathe, bahwa efisiensi thermal dapat dinaikan apabila perbandingan kompresi juga dinaikan. Penelitian ini bertujuan untuk menguji pengaruh unjuk kerja motor diesel pada setiap kenaikan perbandingan kompresi. Metode penelitian yang digunakan melalui uji eksperimental pada motor diesel 1 silinder putaran konstan berbahan bakar pertamina dex, dengan pengereman motor melalui pembebanan elektrik pada generator dengan 3 kali perubahan perbandingan kompresi lebih tinggi dari kondisi normalnya (21:1). Hasil penelitian menunjukan bahwa, prestasi tertinggi didapatkan pada perbandingan kompresi 21,78:1. Dimana daya dan torsi motor rata-rata meningkat 2,35%, Daya rata-rata tertinggi 1125 W; Torsi rata-rata tertinggi 7,162 Nm. Sedangkan Sfc rata-rata terendah 0,571 kg/kWh atau menurun 3,05%. Tetapi pada perbandingan kompresi 23,54:1 dan perbandingan kompresi 22,62:1 prestasi mesin menurun dari variasi perbandingan kompresi 21,78:1. Hal ini disebabkan waktu penginjeksian bahan bakar masih standar sedangkan kompresi motor diesel sudah sangat tinggi.

The diesel motor is the motor with an internal combustion on the actual process is triggered by a high temperature compression in the cylinders. Comparison of a low compression resulted in the performance of the resulting motor diesel is not a maximum, even cause knocking. Basing on thermodynamic system for constant pressure cycle or sabathe cycle thermal efficiency, that can be offered up in the comparison of compression also offered up. This research aims to test the influence of diesel motor performance on any increase in comparison of compression. The research method used in experimental trials through the diesel motor 1 cylinder round constant fuel pertamina dex, with electric motor braking through imposition on generator with 3 times higher compression comparison change from its normal condition (21:1). Results of the study showed that the highest achievement, obtained at 21,78 compression comparison: 1. Where is the power and torque of the motor's average increased 2.35%, the highest average Power 700 W; The highest average torque 7,162 Nm. Whereas the lowest average Sfc 0,571 kg/kWh or declined 3.05%. But in a comparison of compression 23.54:1 compression comparison 22,62:1 achievement comparison variation decreased from engine compression 21,78:1. This is due to time penginjeksian standard while still fuel compression motor diesel is already very high.

Diesel motor is a motor with a combustion in which the combustion process is triggered by compression at elevated temperatures in the cylinder. Low compression ratio resulting in performance that produced a diesel engine was not optimal, even causing knocking. Basing on the thermodynamic system for constant pressure cycles and cycles sabathe, that the thermal efficiency can be increased when the compression ratio is also raised. This study aimed to examine the effect of the performance of the diesel engine on any increase in compression ratio. The method used by the experimental test on one cylinder diesel engine fueled constant rotation Pertamina dex, with the motor braking via the electric load on the generator with 3 times higher compression ratio changes from normal conditions (21: 1). The results showed that the highest achievements obtained at a compression ratio of 21.78: 1. Power and torque of the motor where the average rose 2.35%, the highest average power 1125 W; The highest average torque of 7.162 Nm. Sfc while the lowest average 0.571 kg / kWh, down 3.05%. But at a compression ratio of 23.54: 1 and a compression ratio of 22.62: 1 achievement of variation decreased engine compression ratio 21.78: 1. This is due to the time injection of fuel is still the standard compression while the diesel engine is already very high.
