piston engine Flashcards
in the first stroke what is it called
induction
2nd stroke is called?
compression
3rd stroke is called
Power
4th stroke is called
Exhaust
in the first stroke the velocity temperature pressure and mass is?
V= increasing T= Decreasing P= Decreasing m= Increasing
in the second stroke the velocity temperature pressure and mass is?
V= Decreasing T= Increasing P= Increasing m= Constant
in the third stroke the velocity temperature pressure and is?
V= C T= Increasing P= Increasing
in 1483 Leonardo
Da Vinci conceived a flying machine he called the ——–
Aerial Screw
in the fourth stroke the velocity temperature pressure is?
Pressure = Increasing T= Increasing V= N/a
When did leonardo davinci invented his aerial screw
1438
These have their cylinders arranged in a straight line,
one after the other, they can be liquid or
air cooled.
Inline Engines
In fact, the first patent for heat engine was taken out in —— by
——–, unfortunately, Barber’s engine was neither efficient
nor practical.
1791 John Barber
In ——, —– of France built the first practical piston
engine. Leinor’s engine which employed a battery ignition system
and used a natural gas for fuel operated industrial machinery as
lathes.
1860 Etienne lenoir
The next major breakthrough in piston engine development came in
—– when ———– developed the FOUR – STROKE,
FIVE – EVENT CYCLE. The OTTO CYCLE is still in used in most
modern reciprocating engines.
Dr. Agust Otto
These engines powered the
fighter aircraft of World War 2. Liquid cooled, the V
arrangement of cylinders could easily be streamlined into the
fuselage so reducing drag.
V engine
gave a large frontal area to the aircraft, but was short in length. The pistons are arranged
radially around a single crank.
Radial Engine
How many degrees if a four stroke complete 1 cycle
720 degrees
The internal diameter of the cylinder is called the —-.
Bore
Per stroke how many degrees
180 degrees
The movement between tdc and bdc
Stroke
movement in the piston
Crank throw
