PISTON ENGINE PROPULSION Chapter 3 Piston Engines Types Different layouts of various piston engine 2014 Hyundai Engine 1933 Alvis Engine
Piston Engine Types - Layouts Vee Twin Inline 3 Inline 4 Single Inline 5 Vee 5 Vee 6 Vee 8
Piston Engine Types - Layouts Horizontally Opposed (Or flat) 4 Firing Order :- Vee 8 Firing Order :- 1 – 4 – 3 – 2 1 – 8 – 4 – 3 – 6 – 5 – 7 – 2
Stroke 1 Piston at TDC Stroke 2 Piston at BDC Piston Engine Types - Layouts Piston Engine Types – 2 Stroke Cycle Port C - Exhaust Port B – Cylinder Inlet Piston rising pulls fuel/air mixture into crankcase; compression causes combustion Port A – Crankcase Inlet Piston pushed down forces fuel/air mixture into cylinder which pushes exhaust gases out
Mechanical Arrangement – Deisel Direct Injection Indirect Injection Inlet Exhaust Engine Cross Section Same mechanical set-up as petrol engine Combustion initiated by hot compressed air But no spark plugs!
Mechanical Arrangement – Wankel Engine Casing Rotating Triangular ‘Piston’ Fixed (non-rotating) Pinion Inlet Port Rotating ‘Crankshaft’ Exhaust Port Spark Plug Output Shaft Engine Cross Section The piston rotates around the fixed pinion But the shape of the piston and the casing also make the piston move up and down by a small amount as well This motion drives the rotating crankshaft Which in turn drives the output shaft Points of contact marked in yellow
Chamber A Chamber B Inlet Port Exhaust Port Chamber C Engine Cycle Mechanical Arrangement – Wankel Engine
Cylinders Crankcase Le Rhone Valve Gear Propeller Mount Bolts Valve Pushrod Spark Plug Mechanical Arrangement – Radial/Rotary Engines
Mechanical Arrangement – Radial/Rotary Engines Radial/Rotary Radial Rotary Aircraft Nose Aircraft Nose (viewed from the side) (viewed from the side) (viewed from the front) Model aero engine Radial powered motorbike 28 Cylinder Radial
Mechanical Arrangement – Engine Size Flat Twin Hand Held To fairly big! Is there any limits to size? They go from tiny: -
Mechanical Arrangement – Engine Size Cylinder Head Bolts Cylinder Liners Cylinder Block
Mechanical Arrangement – Engine Size Crankshaft Flywheel
Mechanical Arrangement That was a brief explanation of various internal combustion engine variants There are more variations to be found on the internet
