IME Diesel Latest Update Graded A+ Stroke Length the piston travels from the upper most position to the bottom most position Diesel Fuel minimum compression ratio 12:1 Intake Valves Admit air into cylinder for combustion Exhaust Valves Allow for removal of combustion byproducts from cylinder Fuel injector supplies fuel for combustion What is needed to run a Diesel engine Fuel for combustion, Air for combustion, Cooling water to remove heat, Lubricating oil to lubricate and cool internal moving parts, and method to exhaust Compression Stroke Occurs as the piston moves upward in the cylinder with both valves closed. During this stroke, the air-fuel mixture is compressed into a smaller space. 4 stroke engine each event is associated with its own stroke (2 revolutions) 2 stroke engine cycle needs 1 complete revolution to complete 1 whole cycle 3 requirements for combustion fuel,ignition, oxygen Compression stroke Occurs as the piston moves upward in the cylinder with both valves closed. During this stroke, the air-fuel mixture is compressed into a smaller space. Intake Stroke Piston stroke in which the piston travels downward in the cylinder with the intake valve open. This increases the volume above the piston and creates a partial vacuum that draws the air-fuel mixture into the cylinder. combustion stroke As the piston reaches the top, fuel is injected at just the right moment and ignited, forcing the piston back down. 2 strokes more common with slow speed diesels Engine Cycle intake, compression, combustion, exhaust Top of the Piston Crown Bottom of Piston skirt Connecting Rod Attaches to wrist pin and skirt Why are the opening staggered? To prevent leaks Big end of Connecting Rod Crankshaft End fuel pump meter or control amount of fuel going into the injector Brain of the engine Camshaft
