Making process

What’s diesel engine?

Kind of engine Outline( 개요 )ship propulsion engine used that is used as Main Engine it’s a low-speed diesel engines used in 2-Stroke engine Generator Engine that is used as a medium of engine, 4-Stroke are mainly used in the Generator Engine

structure

2-stroke structure(used in ship engine)

See easy right ? :-)See easy right ? :-)

4-stroke structure (used in generator engine)

Main component


Main component

Combine all parts (diesel ship engine)

basic principle of(mechanical) motion


2-stroke engine 4-stroke engine

2-stroke engine When up stroke cycle compression and inhale( 흡입 ) ,ignition( 점화 ) Down stroke cycle explosion, exhaust( 배기 ) This feature is low component and weight per power is good! But too many fuel consumption( 소비 )

4–stroke engine it is inhale, compression, explosion, exhaust in regular sequence ( 순서대로 ) This stroke feature low fuel consumption and rev count(rpm) is high But too many component and weight per power is not good

Making process

1.Raw material making

Moulding( 주형뜨기 ) Steel making by an electric furnace ( 전기로 )

Ingot( 주괴 ) forge welding ( 단조 ) make Raw Material

Bearing Support Use casting( 주조 ) make the shape Bearing Support after cavity mill( 황삭가공 )

Piston Rod Used Material of Piston Rod and make it(Piston Rod)

Connecting Rod forge welding of Ingot and then Making Connecting Rod

2. Fabrication & machining

Bed Plate &Frame Box Welding bed plate and Frame Box add steel plate

Bed Plate Use welding making shape Assembly point deep procession

Crank Shaft Fitting Crank Throw and Flange Make shaft and then outside deep procession

Frame Box after boiler making and Assembly point deep procession
