Description
Valve Arrangement
According to the valve arrangement of the inlet and exhaust valve
in various positions in the cylinder head or block, the automobile
engines are classified into four categories. These arrangements are
named as ‘L’, ‘I’, ‘F’ and ‘T’. It is easy to remember the word
‘LIFT’ to recall the four valve arrangement.
Different Types of Engine
(i). L-head engine: In these types of engine, the inlet and exhaust
valves are arranged side by side and operated by a single camshaft.
The cylinder and combustion chamber forms and inverted L.
(ii). I-head engine: In I-head engines, the inlet and exhaust
valves are located in the cylinder head. A single valve actuates
all the valves. These types of engine are mostly used in
automobiles.
(iii). F-head engine: It is a combination of I-head and F-head
engines. In this, one valve usually inlet valve is in the head and
the exhaust valve lies in the cylinder block. Both the sets of
valve are operated by the single camshaft.
(iv). T-head engine: In T-head engines, the inlet valve located at
one side and the exhaust valve on other side of the cylinder. Here
two camshafts are required to operate, one for the inlet valve and
other one is for the exhaust valve.

Types of cooling
On the basis of types of cooling, the engines are classified as:
(i). Air cooled engines: In these engines, the air is used to cool
the engines. In air cooled engines the cylinder barrels are
separated and metal fins are used which provides radiating surface
area that increase cooling. The air cooled engines are generally
used in motorcycles and scooters.
(ii). Water cooled engines: In water cooled engines, the water is
used for the cooling of engine. Water cooled engines are used in
cars, buses, trucks and other four wheeled vehicles, heavy duty
motor vehicles. An anti-freezing agent is added in the water to
prevent it from freezing during cold weather. Every water cooled
engines has radiator for the cooling of hot water from the engine.
