The bore of each cylinder in a six-cylinder car engine is 45 mm and the stroke each piston is 125 mm. calculate the cubic capacity of the engine in cubic centimetres (cm³); and calculate the clearance volume per cylinder for a compression ratio, r. of 8.75.

The rest of the questions are thus: 4) Calculate the air temperature and pressure in the pump at the end of the following expansion stroke, just before the piston uncovers the orifice (orifice dimensions are neglectable).5) Calculate the mass and temperature of air in the pump (i.e. the cylinder andconnecting pipe) after the orifice has been exposed and the pressure has risen to atmospheric pressure (bottle valve is now closed).7) Calculate the piston position and the air temperature in the pump during the next compression stroke at the time when the valve to the gas bottle opens again.8) Calculate the pressure in the bottle when no more air can be transferred by the pump. (This will be after an undetermined number of pumping cycles).

A punch press has punches forty (40) circles that are 2 inches in diameter through medium carbon steel that is 0.125” thick. If six hydraulic cylinders are used to achieve this force, what diameter cylinders are required if the pump has a maximum continuous operating pressure of 3150 psi?

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?

You are asked to design a four cylinder four-stroke spark ignition engine for a passenger car, which is required to provide a maximum brake torque of (2.60x10^2) Nm at the rated speed of (7.000x10^3) rpm. To simply the design, the bore (B)/stroke (L) ratio is assumed to be unit, i.e. B=L. Given that the bmep of the engine is assumed to be (7.000x10^2) KPa, find its mean piston speed. The answer should be in the unit of m/s with 3 significant figures. Note: Your answer is assumed to be reduced to the highest power possible. Your Answer: Question 7 options:       x10       Answer

For the Internal Combustion Engine test that you conducted, sketch the P-V diagram showing thesuction, compression, power and exhaust strokes. Label the events on the diagram. Indicate where themaximum pressure occurs

Question: Please compute the compression ratio of an engine that has a bore of 5 inches and a stroke of 5 inches when the volume at the combustion chamber is 16.36 cubic. in. with the piston at TDC.   Please provide a complete solution. Thak you!

Q: A multi disc clutch is used to transmit to 10 kW power at 900 rpm. If the external diameter of friction lining is 1.25 times the internal diameter, find the required dimensions of the friction lining and the axial force exerted by the oil chamber pressurized to engaged the disks a with disks b. The pressure between disks is limited to 0.085 N/mm?. Assume average service condition. The coefficient of friction may be taken as 0.3.
