A 4 cylinder 4 stroke 2.3 L diesel engine with bore = 12.4 cmand stroke =11 cm. the crank radius is 6.2 cm and with a connectingrod length 15 cm. the compression ratio of the engine is 20 and thecombustion efficiency is 97.3 %. If the average speed of the carover the running life of the engine is 56 km/h and the totaltraveled distance of the engine is 250000 km.note: use the engine speed as 2300 rpm wheneverneeded, mechanical efficiency is 73 %, indicated work produced fromeach cycle each cylinder is 1400J, and assume that the injectionstarted 10 degrees bTDC and ends at 25 crank angle degree aTDC.
Determine:
- The volume of the BDC.
- The amount of the fuel that didn’t burned in the combustionchamber .
- The rate of the air flow to the engine if the volumetricefficiency is 70 %.
- The number of the exhaust strokes that have been happenedduring the engine life in one cylinder.
- Indicated mean effective pressure.
- The torque produced from the engine.
- The time duration for the injection process.
- The position of the piston at the end of the injectionperiod.
- The volume of the combustion chamber at the moment of theinjection process.
- If the mass floe rate of the fuel used if A/F is 19.3kgair/kgfuel.
- The specific power of the engine.
- Based on the dimensions of the bore and the stroke, is thisengine square engine or over or under square one?
