Study on Premixed Combustion in a Diesel Engine with Ultra-multihole Nozzle

Table 4

Test operating conditions.

Operating	Speed	Torque	Mean effective pressure*
condition	(r/min)	(N·m)	(MPa)
A	1000	62	0.119
B	1000	155	0.297
C	1000	215	0.412
D	1400	300	0.575

*Mean effective pressure = torque × τ/(318.3 × Vs).
Where τ means stroke number, four stroke is 4 and two stroke is 2.
Vs means displacement (l).
