SHOCK ABSORBERS/ DAMPERS: WORKING PRINCIPLE, CLASSIFICATION, AND FUNCTIONS
July 3, 2020 Mechanical Engineering FAHADH V HASSAN

Shock absorbers are basically oil pumps. A piston is attached to the end of the piston rod and works against hydraulic fluid in the pressure tube. As the suspension travels up and down, the hydraulic fluid is forced through tiny holes, called orifices, inside the piston. However, these orifices let

CAMSHAFT SENSOR FUNCTION: FUNCTIONAL PRINCIPLE
June 3, 2020 Mechanical Engineering FAHADH V HASSAN

The task of the camshaft sensor is to work with the crankshaft sensor to define the exact position of the crankshaft drive. Through the combination of both sensor signals, the engine control unit knows when the first cylinder is in the top dead point. This information is needed for three

What is Torque?
April 20, 2020 Mechanical Engineering FAHADH V HASSAN

What is torque? Torque is a measure of the force that can cause an object to rotate about an axis. Just as force is what causes an object to accelerate in linear kinematics, torque is what causes an object to acquire angular acceleration.Torque is a vector quantity. The direction of

OIL PUMP: TYPES, DRIVE MECHANISM, ELECTRONIC OIL PUMP
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

The oil pump is the heart of the lubrication system. It sucks oil up from the oil pan and forces it around oilways in the engine before the oil drops back into the sump and is recirculated. The oil pump is a highly critical part of the engine – if

DISTRIBUTORLESS IGNITION SYSTEM / DIS /: COMPONENTS, WORKING PRINCIPLES, AND TYPES
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

Distributorless Ignition System (DIS) is the ignition system in which the distributor of the electronic ignition system is replaced with number of induction coils i.e. one coil per cylinder or one coil for pair of cylinders, and the timing of the spark is controlled by an Ignition control unit (ICU)

ENGINE LUBRICATION SYSTEM: WORKING PRINCIPLE, COMPONENTS, AND IMPORTANCE
March 10, 2020 Mechanical Engineering FAHADH V HASSAN

When two metallic surfaces under direct contact move over each other, they create friction which generates heat. This causes excessive wear and tear of those moving parts. However, when a film of lubricating matter separates them from each other, they do not come in physical contact with each other. Thus,
