Study Notes

I.C. Engine History and Development

Thermal efficiency of an internal combustion (I.C.) engine is less than that of an external combustion (E.C.) engine.
Weight-to-power ratio is lower in I.C. engines compared to E.C. engines.
I.C. engines can be single- or double-acting.
A four-stroke diesel engine is an internal combustion engine.
I.C. engines were invented around 1872
Dr. Rudolf Diesel developed the first diesel engine in 1892.
A petrol engine is a type of spark ignition engine.

I.C. Engine Types and Models

Deutz engine Model BF12L 513C is fitted on Plasser BCM and is air-cooled.
Cummins engines fitted on track machines are usually air-cooled.
The ΚΤΑ 1150-L engine has 12 cylinders.
The Kirloskar HA-694 engine, used on PQRS,is a 6-cylinder engine.
The Deutz Engine Model BF 12L 513C is an 8-cylinder engine.
The Cummins Engine Model NTA-855L has a total displacement volume of 855cm³.

I.C. Engine Constructional Details

Oil sumps are typically made of cast iron, aluminum, forged steel, or copper.
4-stroke Engines use a minimum of two compression rings.
4-stroke Engines use a minimum of two oil control rings.
Piston and connecting rods are joined by a gudgeon pin.
The small end of a connecting rod connects to the piston.
The center-to-center distance between crankpin and main journal is equal to the piston stroke.
The number of teeth on the camshaft gear is equal to the number of teeth on the crankshaft gear.
The camshaft rotates twice as fast as the crankshaft.

I.C. Engine Working Principle

The highest point a piston can reach going upwards in the cylinder is called Top Dead Center (TDC).
The lowest point a piston can reach going downwards in the cylinder is called Bottom Dead Center (BDC).
The complete movement of a piston from TDC to BDC (or vice-versa) is called a stroke.
The volume above TDC is the clearance volume.
The volume between the TDC and BDC is the swept volume.
The diameter of the engine cylinder is called the bore.

I.C. Engine Fuel Combustion

The specific gravity of high-speed diesel is between 0.82-0.92 and 1.24-1.26.
The minimum cetane number (CN) for high-speed diesel fuel is 30.
High-speed diesel may contain up to 3% sulphur as an impurity.
Incomplete combustion produces carbon monoxide (CO).
1 part carbon monoxide is present in 10,000 parts of air.
