Question

The expressions for diesel engine compression ratio and diesel engine power are :-

• A. $r_c=\frac{V_d-V_c}{V_c};P=2NT$
• B. $r_c=\frac{V_d+V_c}{V_c};P=2\pi NT$
• C. $r_c=\frac{V+V_d}{V_d};P=\frac{2\pi T}{N}$
• D. $r_c=\frac{V+V_c}{V_c};P=\frac{2\pi N}{T}$

Answer 1

Answer: (B)

$r_c=\frac{V_d+V_c}{V_c};P=2\pi NT$

Answer 2

The correct answer is (B) : $r_c=\frac{V_d+V_c}{V_c};P=2\pi NT$.
