Engine Classifications

+Number and Arrangement of Engine Cylinders
~Engine Cylinders Arrangement
1.) In a row
-in line type engine
2.) In two rows or banks set at an angle
-v type engine
3.) In two rows or bank opposing each other
-flat kung san may cylinder na nakaoppose
-boxer engine
4.) Like spokes on a wheel
-radiant type
-rotary radial engine

1-3 only engine that were used in automobile
4 only a prototype and never been used in automotive vehicle as shown in electude

Abbreviation for cylinders
IVORW
SVORW


+Three Cylinder Engines
-over head crankshaft
-60 hp/ 145 kilowatts/ 5500 rpm
-crankshaft and camshaft is hollow
-cylinder liner is cast in or made of iron
~sold in United States
~made in Japan

-circle represent the crankshaft under the cylinder
-has a timing chain
2.) In a V
-two rosed bank
-showing the angle
-separated from flaps
-with a 60 degrees but before it had 90 degrees
3.) Opposed
-seperated
-180 degrees

~Value train

~V is the engine type, the number is how many the cylinder in the engine
~For 8 cylinder may 16 valves/ valves is alway double the amount
EX: I4 -In line engine 4 cylinder
V6 - V engine 6 cylinder
+5 cylinder
+6 cylinder
+8 cylinder
+10 cylinder
+12 cylinder
-jaguar
-bmw
+16 cylinder
-bugatti
-lambo


+Engine Classifications
1.) Number of Cylinders
2.) Arrangement of cylinders
3.) Arrangement of valves and valve trains
4.) Type of cooling
5.) Number of strokes per cycle
6.) Type of fuel burned
7.) Methods of Ignition
8.) Firing Order
9.)
10.)


+Valve Train Mechanism
1.) Cam Flow
2.)
-cam shaft, rocker arm, taphet, push rods
3.)
-push rod less/ cam shaft only and rocker arm
4.)
-camshaft, taphet, pag naeliminate ang push rod si taphet nalang and itutulak si rocker arm and mag transfer ng force papunta kay valve
5.)



+Difference arrangement of valve that can affect in engine classifications
1.) Location of the Camshaft
-can be seen inside the engine block
~pwede sa gilid na nakaconnect ang push rod and rocker arm papunta sa valve
~makikita sa gilid na malapit sa connecting rod ng makina,
~nasa labas or exposed
2.) How the camshaft driven
~Types of Camshaft Drive
-driven by timing gears/ kadena yung timing chain
-sprockets with timing chain/ timing chain na nakalagay sa camshaft
-sprockets and toothed timing belt
-Combination of Timing Chain and Timing belt
mostly seen in sports car
3.) Type of valve train


+4 Methods of driving the camshaft
1.) Timing Gears
-ang camshaft nasa engine block
2.) Timing Chain
3.) Timing Chain
4.) Timing Belt

~Oil Pump and distributor is connected to the camshaft
~

+Engine
-Mechanical Fuel Pump/ Electronic

+Intake Valve ay Malaki ang ulo ng valve
-kasi may hangin at fuel ang pumapasok
+Exhaust valve ay maliit ulo ng valve
-dahil burn gasses lang ang lumalabas
+butas sa gitna
-nakalagay ang spark plug pag gasoline engine
-injector pag direct fuel engine

+Engine Rotation
-pag nakatingin sa harap, crankshaft rotates clock wise


+Cylinder numbering
1- may pulley
6- guide wheel
-depende kung pano ang pagkakapwesto

+Opposed Cylinder Engines
-magkabilaan
-1955 year model 'porsche 550 spyder'

+Cylinder Bank
~Straight - inline engine

+bank angle- top dead center ang una, ang pangalawa hindi

+Firing Order
-distributor/ the sequence which deliver the power strokes

~avoid firing 2 cylinders in 1 time
but 1 after another
~pag sabay sabay, mag baback fire kung san masisira ang mechanical part or the engine itself

-detonation, explosion or advance deformation

-kung san tumatapat ang rotor yun ang nagbibigay ng lakas ng current

+Inline engines
-common firing engine in i4, has 4 cylinder with an arrangement os 1342
-6 cylinder 153624
-V6 123456
-pwede magkakaiba ang order depende sa manufacturer
-V8
