Different layouts of various piston engine ENGINE TYPES Piston Engines Types Different layouts of various piston engine

Piston Engine Types - Layouts Single Vee Twin Inline 3 Inline 4 Inline 5 Piston Engine Types - Layouts

Piston Engine Types - Layouts Vee 5 Vee 6 Vee 8 Piston Engine Types - Layouts

Horizontally Opposed (Or flat) 4 Piston Engine Types - Layouts Vee 8 Firing Order: - 1 – 4 – 3 – 2 1 – 8 – 4 – 3 – 6 – 5 – 7 – 2 Piston Engine Types - Layouts

Piston Engine Types – 2 Stroke Cycle Piston at TDC Stroke 1 Port A – Crankcase Inlet Port C - Exhaust Port B – Cylinder Inlet Piston rising pulls fuel/air mixture into crankcase; compression causes combustion Piston at BDC Stroke 2 Piston pushed down forces fuel/air mixture into cylinder Piston Engine Types – 2 Stroke Cycle

Mechanical Arrangement – Petrol Diesel Direct Injection Engine Cross Section Indirect Injection Inlet Exhaust Same mechanical set-up as petrol engine Combustion initiated by hot compressed air But no spark plugs! Mechanical Arrangement – Petrol Diesel

Mechanical Arrangement – Wankel Engine Engine Cross Section Casing The piston rotates around the fixed pinion Rotating Triangular ‘Piston’ But the shape of the piston and the casing also make the piston move up and down by a small amount as well Fixed (non-rotating) Pinion Inlet Port Rotating ‘Crankshaft’ Output Shaft Exhaust Port Spark Plug This motion drives the rotating crankshaft Points of contact marked in yellow Which in turn drives the output shaft Mechanical Arrangement – Wankel Engine

Mechanical Arrangement – Wankel Engine Engine Cycle Chamber A Chamber B Inlet Port Exhaust Port Chamber C Mechanical Arrangement – Wankel Engine

Mechanical Arrangement – Radial/Rotary Engines Le Rhone Cylinders Crankcase Propeller Mount Bolts Valve Gear Valve Pushrod Spark Plug Mechanical Arrangement – Radial/Rotary Engines
