Two Stroke and Four Stroke Engines:
In the two stroke engines thermodynamic cycle is completed in One revolution of crank shaft whereas in 4 stroke engines the cycle is completed in 2 revolutions of crank shaft. For same capacity and speed nearly 2 times power is developed in 2 stroke engine as compared to 4 stroke engine. But as high compression ratios cannot be achieved in 2 stroke engines, the efficiency of 2 stroke engine is less as compared to 4 stroke engines. Furthermore, the engines can be classified as Spark Ignition engines that operate with the petrol as fuel and Compression ignition engines that operate with diesel as fuel.
What are various types of damping ? Explain viscous damping. A vibrating system is defined by the following parameters : m = 4Kg, K = 10N/m, C =3N-Sec/m Evaluate (a) Na
All shell and head joints shall be double-welded butt joints with full penetration. In cases where double welding is impractical, the root pass shall be made by the GTAW process.
Gas welding is a method of joining two metal pieces (similar or dissimilar) together by melting and fusing their edges at the joint. It involves applying intense concentrated flam
