CYLINDER HEAD

Introduction:

                Internal combustion engines are, simply said, air pumps. The more air you pump into an engine, the more air/fuel you can burn, and the more power you can make. Building horsepower is not quite as simple as that, but it's the basic concept. The cylinder head is the main component that flows air/fuel in and exhaust gases out.

  1. There are various types of cylinder heads and the valve arrangements.
  2. The cylinder heads of T-type and F-type are used with inferior fuels having lower octane number because these heads run at cooler temperatures.
  3. In modern automobile engines, cylinder heads of I-type and overhead type are commonly used.
  4. The cylinder heads reduce cooling losses and the engine efficiency is also increased.

PISTON RINGS

Image
Introduction: Piston rings are provided on the piston. These are used to seal the high pressure side (cylinder) and low pressure side (crank case), i.e. to prevent leakage of gases. There is one oil ring also which is used to scrap the lubricating oil at the cylinder surface so that it returns to crank case. Pistons ring details:                                                                                     Fig:  Piston rings   Rings seal the compression in the combustion chamber and the motor oil in the crankcase. Automotive engines use 3 rings: 2 compressions and 1 multi-piece oil ring. Rings are usually ...

Introduction:                  For selecting a gearbox, its structure type, installation form, bearing capacity, output rotational speed, working conditions and other factors shall be considered.   Types of the gear box: (a) Selective type gear boxes:                 (i) Sliding mesh gear box                 (ii) Constant mesh gear box                 (iii) Synchromesh gear box (b) Progressive type gear box (c) Epicyclic type gear box. Sliding Mesh Gear Box:    It is simplest type of gear box out of the available gear boxes. In this type of gear box, gears are changed by sliding one gear on the other. This gear box consists of three shafts; main shaft, clutch shaft and a c...
