What is piston/how piston work/piston's functions.

 PISTON  A piston of an internal combustion engine is in the form of an inverted bucket shape and it is free to slide in the cylinder barrel. The gas tightness is secured by means of flexible piston rings, which are in the grooves of the piston. These grooves are cut in the upper part of the piston. A piston of an internal combustion engine serves three functions: 1. It forms a moveable wall of the combustion chamber. 2. It transmits...

What is crankcase/types of crankceses/how crankcases work

 CRANKCASE :        The crankcase supports the cylinders and the crankshaft and is an important structure in the internal combustion engine. It also functions like a housing and protects the engine parts against dust, water and splashing mud. The crankcase stores lubricating oil required for lubricating the engine parts.       The size of a crankcase is sufficiently large as it accommodates...

What is Cylinder liner/ materials for cylinder liners/types of liners/Comparison the Liners

  CYLINDER LINER         The cylinder liner is a sleeve in which the piston of an engine reciprocates. The life of a cylinder between its re-bores depends two main factors:  (i) Abrasion, and (ii) Corrosion         Abrasion depends on the atmospheric con- dition and the efficiency of the air filter and oil filter. Dusty atmospheric air is more harm- ful as it increases abrasion...

What is supercharger/ how supercharger work/ types of superchargers.

 Supercharger:        A supercharger is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the engine more oxygen, letting it burn more fuel and do work, thus increasing power.         Power for the supercharger can be provided mechanically by means of a belt, gear, shaft, or chain connected...

Types of Carburetors / Constant Choke Carburetor / Constant Vacuum Carburetor / Multiple Venturi Carburetor

 Types of Carburetors:        There are three general types of carburetors depending on the direction of flow of air. The first is the up draught type shown in Fig.1 (a) in which the air enters at the bottom and leaves at the top so that the direction of its flow is upwards. The disadvantage of the up draught carburetor is that it must lift the sprayed fuel droplet by air friction. Hence, it must be designed for relatively...

Fuel Injection system for SI engines /Carburetion /Factors Affecting Carburetion/Definition of Carburetor/Principle of Carburetion

 Fuel Injection system for SI engines:1.1. CarburetionSpark-ignition engines normally use volatile liquid fuels.Preparation of fuel-air mixture is done outside the engine cylinder and formation of a homogeneous mixture is normally not completed in the inlet manifold. Fuel droplets, which remain in suspension, continue to evaporate and mix with air even during suction and compression processes. The process of mixture preparation is extremely...

CRDI - (Common rail fuel injection system) / CRDI Working Principle.

 CRDI - Common rail fuel injection system:         Common rail direct fuel injection is a modern variant of direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (over 1,000 baror 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common...
