History of IC Engines
Teknologi dan Rekayasa
1860 Lenoirs engine (a convertedsteam engine) combustednatural gas in a double actingpiston, using electric ignition
1876Nikolaus Otto patented the 4 cycle engine, it
used gaseous fuel1882 Gottlieb Daimler, an engineer for Daimler, left
to work on his own engine. His 1889 twin
cylinder V was the first engine to be produced
in quantities. Used liquid fuel and Venturi type
carburetor, engine was named Mercedes after
the daughter of his major distributor
1893 Rudolf Diesel built successful CI engine
which was 26% efficient (double the efficiency
of any other engine of its time)

Complementary Technologies
Teknologi dan Rekayasa
1. Pneumatic tires (1888,
Dunlop)
2. Cheap liquid fuels (Oil
industry born in PA 1859)
3. Venturi effect carburetor
(1892, Willi Maybach)
4. Variable mechanical
transmission (primitive
type by Levassor, 1891)
5. Electric starter (Kettering1912)

4 Cycle Process
Teknologi dan Rekayasa
4 Stroke Engine:
Every 2x rotation of crank shaft or 4x
movement of piston yields 1x Power

4 Cycle Process
Teknologi dan Rekayasa
Intake StrokeIntake valve opens,
admitting fuel and air.
Exhaust valve closed
for most of stroke

4 Cycle Process
Teknologi dan Rekayasa
Compression Stroke
Both valves closed,
Fuel/air mixture is
compressed by risingpiston. Spark ignites
mixture near end of
stroke.

4 Cycle Process
Teknologi dan Rekayasa
Power Stroke
Fuel-air mixture burns,
increasing temperature
and pressure, expansion
of combustion gases
drives piston down. Both
valves closed - exhaust
valve opens near endof stroke

4 Cycle Process
Teknologi dan Rekayasa
Exhaust Stroke
Exhaust valve open,
exhaust products are
displaced from cylinder.
Intake valve opens
near end of stroke.
