Ignition Lag or Delay Period:

It is the duration between the occurrence of the spark at the spark plug and the duration of the combustion curve from the motor curve. Factors influencing this phase are:

Nature of fuel
Mixture ratio
Initial temperature
Pressure
Temperature of the flame between the spark plug electrodes

NDT Weld inspection for Aero Components | NDT Inspection and Testing | Ultrasonic Weld Inspection

01-Non-Destructive-Testing-in-aerospace-applications

Non Destructive Testing (NDT) is a method of testing the material’s characteristics such as physical, chemical and structural components to perform their function in a cost effective way. In this, components are examined / evaluated without destroy / damage of the product. NDT tests conducted in the parts aren’t damage the raw materials as such happened in destructive methods and it guaranteeing the safe operation of the parts. NDT is no way alters the components in any type of inspection. NDT is carried out widely for the conditioning monitoring (industrial inspections) of the plants such as aerospace, automobile, manufacturing and construction.

Types of Pneumatic Conveyor | Vacuum and Positive Pressure Pneumatic Conveying Systems | Dense Phase Pneumatic Conveying System

01-toper-coffee-loader-conveyor-pneumatic-conveying-systems

Pneumatic conveying systems can be classified on different basis of consideration. These basis are listed below:

On average particle concentration (modes)
On air pressure (Types of systems)
On air supply arrangement
On solid feeder type

Of these, the first two are very important and often influence the choice of the specific design for a given material, loading and delivery condition and the distance to be covered.

Engine Variable valve Actuating Mechanisms | Valve Train System and Components | Variable Valve Timing Technologies

Valve Actuating Mechanisms: Each valve must open at the proper time, stay open for the required length of time and close at the proper time. Hence the timing of the valves are controlled by valve actuating mechanisms. Intake valves are just open before the piston reaches the Top Dead Centre (TDC), and exhaust valve remain open after TDC. At this

Brazing Technology is a joining process in which a filler metal is melted and dispersed by capillary action between the faying surfaces of the metal parts being joined. No melting of the base metals occurs in brazing; only the filler metals are melted. In brazing, the filler metal (also called as brazing metal), has a melting point is above 840° F (450° C) but below the melting point of the base metal to be joined. Tensile strength of the joint is about 40000 psi.

Underwater Welding | Underwater Welding Dangers | Hyperbaric Welding

79fbe 01 small habitat under water welding dry hyperbaric welding process about underwater welding Manufacturing Engineering Underwater Welding

Underwater welding offers a mode of assembly or repairs the structures underwater. It is a type of technology for repairing marine structures. Unconventional methods such as clamp and grout repairs (which may set up inappropriately high loading on offshore structures), and the use of bolted flanges for the tie-ins, are not necessarily always satisfactory.
