Question
4
Apa fungsi utama penambahan panas pada Siklus Diesel?
What is the main function of heat addition in the Diesel cycle?
Options
a
Menaikkan energi gas kerja sehingga dapat menghasilkan usaha saat ekspansi
To increase the energy of the working gas so it can produce work during expansion
b
Menurunkan tekanan kompresi agar mesin ringan berputar
To reduce compression pressure so the engine turns more easily
c
Mendinginkan ruang bakar sebelum langkah usaha
To cool the combustion chamber before the power stroke
d
Mengurangi kebutuhan udara bilas di dalam silinder
To reduce the need for scavenging air inside the cylinder
