    Shlall RACING CARS.* by HN CHARLES, B.Sc.7

    500 THE INSTITUTION OF AUTOMOBILE ENGINEERS. ShlALL RACING CARS.* By H. N. CHARLES, B.Sc.7 (ASSOCIATEMEMBER.) February, 1935. INTRODUCTION. It is undeniable that everybody with a normal sense of values enjoys a clean sporting contest of any kind between adversaries who are fairly and evenly matched. To make the contest a real test of merit it must take place in public, and must be in accordance with the accepted rules. The above requirements are met by motor racing, since thousands of people witness the great long-distance motor races of the present day. The rules usually are also comparatively strict, and fine sportsmanship frequently exists in addition, in connexion with honouring the unwritten rules of the motor racing game. It has been the author’s good fortune during the last few years to be entrusted with the dcsigning of a number of types of what, for the want of a better term, may be briefly described as “ small racing cars.” The work, as it happens, has been entirely carried out for one Company, whose drawing office and experimental depart- ment are combined under his care. Having previously been in daily contact at different times with motor-cycle engines, airship engines, both rotary and stationary aeroplane engines, and a variety of accessories connected with the various types, it was at first some- what difficult to go back to the beginning and start with small engines all over again, but there is a great fascination about these small units, because they provide an almost ideal ground for experiment, the cost of which is greatly reduced by the small size of the parts involved.

    POWER TRANSMISSION SYSTEM Transmission Is a Speed Reducing Mechanism, Equipped with Several Gears (Fig

    POWER TRANSMISSION SYSTEM Transmission is a speed reducing mechanism, equipped with several gears (Fig. 1). It may be called a sequence of gears and shafts, through which the engine power is transmitted to the tractor wheels. The system consists of various devices that cause forward and backward movement of tractor to suit different field condition. The complete path of power from the engine to the wheels is called power train. Fig 1 Power Transmission system of Tractor Function of power transmission system: (i) to transmit power from the engine to the rear wheels of the tractor, (ii) to make reduced speed available, to rear wheels of the tractor, (ii) to alter the ratio of wheel speed and engine speed in order to suit the field conditions and (iv) to transmit power through right angle drive, because the crankshaft and rear axle are normally at right angles to each other. The power transmission system consists of: (a) Clutch (b) Transmission gears (c) Differential (d) Final drive (e) Rear axle (f) Rear wheels. Combination of all these components is responsible for transmission of power. CLUTCH AND FLUID COUPLING CLUTCH: Clutch is a device, used to connect and disconnect the tractor engine from the transmission gears and drive wheels. Clutch transmits power by means of friction between driving members and driven members. Necessity of clutch in a tractor: Clutch in a tractor is essential for the following reasons: (i) Engine needs cranking by any suitable device. For easy cranking, the engine is disconnected from the rest of the transmission unit by a suitable clutch.

Summary 12. Self assessment 1 1. INTRODUCTION A diesel locomotive must fulfill the following essential requirements- 1. It should be able to start a heavy load and hence should exert a very high starting torque at the axles. 2. It should be able to cover a very wide speed range. 3. It should be able to run in either direction with ease. Further, the diesel engine has the following drawbacks: • It cannot start on its own. • To start the engine, it has to be cranked at a particular speed, known as a starting speed. • Once the engine is started, it cannot be kept running below a certain speed known as the lower critical speed (normally 35-40% of the rated speed). Low critical speed means that speed at which the engine can keep itself running along with its auxiliaries and accessories without smoke and vibrations.
