TECHNICAL LEARNT
ENGINE ASSEMBLY
INTRODUCTION
Engine can be called as heart of automobile. Engines are used for different purposes. The engine used in INTERNATIONAL TRACTORS is of these types. The engine fitted in 740 DI is made by SYMPSONS, which are imported. The engine in 740 & 760 models are assembled in the engine assembly shop. The engine in 50 & 60 H.P. are of two types one is standard model and its design is taken from ZETOR of Checkosolavia and other is fuel efficient model in which crank case and head design is taken from AVL (Auto Vehicle Ltd.0 of Austria). Due to better performance of F.E. model engines the production of standard engines is stopped now.
The engine shop of INTERNATIONAL TRACTOR LTD. is well furnished with latest fitting and checking instruments. . The worker’s in this shop are of high skill level and have lot of experience. The production of shop is about 50 engines per day and can be increased if required. All the component of engines except crankcase is brought from outsides. The shop is having latest engine testing shop and having latest equipment. In testing shop engine is checked for efficiency, specific fuel consumption, power, torque, leakage, rpm and other faults.
ENGINE TESTING
Engine testing is done for checking the performance of newly assembled engine to found out any assemble fault, their H.P., leakage and other faults. Engine testing shop of the I.T.L. is equipped with latest digital control equipments. The engine testing is done with help of turbine (water) or hydro dynamometer. The hydro dynamometer are four in number so that four engine is tested at a time. The shop is equipped with heavy-duty oil filter, which is used to clean the oil from dust or other large particle. The shop has bush pump tester, which is used to test the pump if there are any fault. The engine power is measured on the bases of S.A.E. ratings. The society of automobile engineer’s U.S.A has specified the method of measuring the power output of the engine for standardized purpose. The engine is run without generator, air cleaner, cooling fan etc. However standard circulating pump, fuel pump is fitted to the engine. The horsepower of the engine is measured with dynamometer and measured values are then corrected for the standard pressure, ampere and humidity condition prescribed.
TESTING: -
Before starting the engine the, lubricating oil is filled into the engine and then engine is mounted on the fixture. The flywheel is directly attached to turbine through connecting shaft and engine is started. The engine is made to run for three hour’s to check the engines leakage and if there is any leakage then that fault is found out and again put into the testing and if again there is any fault then that engine is rejected. After minute running the tappet clearance is checked. Tappet clearance is to be kept .25±.005. The clearance is necessary otherwise the thermal expansion of valve will alter the opening or closing of valve angles. After that engine is run at 2400 r p.m. m. for 2.30 hours and then the engine is run at various r.p.m. and loads to calculate the power, b.h.p. and s.f.c. . If the engine is seen to emitting too much smoke than smoke level is also checked.
POWER OUTPUT: -
The engine shop is having latest technology and all the information is available digitally. The load can be increased or decreased r.p.m. or s.f.c. can be changed from within the electronic cabin. Power test is done on 2200 r.p.m. (Maximum r.p.m. of engine is 2400) where torque is rated and is indicated on digital meter. The alteration in r.p.m. is made by varying the load and fuel supply is kept constant.
