3 I0 Engines (i) Suction or Intake Stroke : Suction stroke 0 1 (Fig.1.5) starts when the piston is at the top dead centre and about to move downwards., The inlet valve engines internal is open at this time and the exhaust valve is closed, Fig.1.4a).
Keeping this in combustion view, chapters 1 to 15 are framed so that the book will be useful to both undergraduate and postgraduate students as well as to practising engineers.
Because of one power stroke in two revolutions lesser cooling and lubrica- tion requiiements.1 _ bfations om the engine and the unpleasant odour in the exhaust are the main drawbacks.IC ganesan Engines Third Edition : v, internal M '.Used where low cost, compactness and light weight are important, viz., in mopeds, scooters, motorcycles, hsrid spzayers ganesan etc.Xxii Contents.8 Comparison of Scavenging Methods.9 Scavenging Pumps.l0Advantages and Disadvantages of Two-stroke Engines.l0.l Advantages of Two-stroke Engines.l0.2Disadvanta.BE: ' k combustion S m i dominates except combustion in the smallest and largest engines.The smallest engines are used in mopeds (50 cc engine) and lawn mowers.
