1. A six-cylinder two-stroke engine with a compression ratio = 9 produces a torque of 1100 Nm at a speed of 2100 rpm. It has a bore bof 123 mm and a stroke s of 127 mm. (a) What is the displacement volume and the clearance volume of a cylinder? (b) What is the engine bmep, brake power, and mean piston speed?
An engine of 175 mm bore and 375 mm stroke is governed by hit and miss type governor to 220 rpm. With a fixed setting of the gas supply and ignition advance, indicator diagrams gave the following values of mean effective pressure. Firing, positive loop 5.7 bar, negative loop 0.25 bar; missing negative loop 0.42 bar. When developing 6 kW the explosions were 100 per minute and the gas used was 0.1 m per minute. Calculate the friction power and assuming uniform gas supply per explosion, find the gas consumption per minute at no load.
