Mechatronics, which is also called mechatronic engineering, is a multidisciplinary branch of engineering that focuses on the engineering of both electrical and mechanical systems, and also includes a combination of robotics, electronics, computer, telecommunications, systems, control, and product engineering. As technology advances over time, various subfields of engineering have succeeded in both adapting and multiplying. The intention of mechatronics is to produce a design solution that unifies each of these various subfields. Originally, the field of mechatronics was intended to be nothing more than a combination of mechanics and electronics, hence the name being a portmanteau of mechanics and electronics; however, as the complexity of technical systems continued to evolve, the definition had been broadened to include more technical areas.



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
Temperature of the flame between the spark plug electrodes


Important properties of Engine fuel: Knock rating; Volatility; Calorific value; Gum content; Sulphur content; Aromatic content;

Objects of Lubrication: Primary: To reduce friction between moving parts so as to reduce Power loss Wear of the moving parts Secondary: To provide cooling effect To provide cushioning effect To provide cleaning action To provide sealing action Purpose of Lubrication: To reduce friction To cool down moving parts To Read more…

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 Read more…


Toyota’s GT 86 GRMN, updated version of Toyota’s GT 86 has been revealed ahead of a debut at the 2016 Tokyo Auto Salon in just a few days. It was developed by the official Toyota Gazoo Racing performance division.The GT 86 GRMN aren’t quite as aggressive as what we’ve seen Read more…

Torque converter an Alternate to Gear Box Torque converter is a type of fluid coupling that uses a fluid to transmit turning effort from the one shaft to another. It is a device which performs a function similar to that of a gear box, namely, to increase the torque while Read more…

Fluid flywheel or fluid coupling A liquid coupling is used to transmit engine turning effort (torque) to a clutch and transmission. The coupling is always a major part of the engine flywheel assembly. As such it is sometime called a fluid flywheel. Construction of flywheel The fluid flywheel details can Read more…

Automotive Service Technicians and Mechanics Brake Performance Test of an Automobile The brake performance test of FMVSS 105 defines the minimum needs for the brake system on any vehicle driven on the road. The technician should know a bit about the performance test, not for the sake of being able Read more…

Wet Multi plate clutch  Construction A multiple plate clutch has more number of clutch plates. A typical clutch consist of the following components: Clutch basket or cover, clutch hub, drive (friction) plates, driven (steel) plates, pressure plate and the clutch springs. These can be seen in the picture. The clutch Read more…
