ASSIGNMENT 5

OBJECTIVE: To do thermodynamics analysis of an engine for tractor application for use in India with following targets:

MODEL DISCRIPTION:

TAFE 7502 DI 2WD is used in the following:

This modelconsist of four cylinder, each have two intake ports and two exhaust ports.
The total displacement in the engine is 3.5 L.

Project Planning:

Firstly an intercooled diesel engine is selected.
After that the six cylinder engine model is converted into four cylinder engine.
Then the eight port model is converted into sixteen port model.
Then the intake air pressure after the compression is fed as 2.5 bar and fuel ejection per cycle as 50mg.

Case Setup:

Three cases has been taken, that are:

1. rated speed(2200rpm)

2. speed at max. power(2100rpm)

3. speed at max. torque(1400rpm)

RESULT:

1.As we have seen here the max power is limited to 75 Hp.

2. The bsfc is also with in the range that is 225g/kWh to 210g/kWh.

It is seen here that at 1400 rpm it has 258N-m instead of 294N-m which is approx 10% deviation from the given rated value.

Similarly at 2200 rpm, it has 58.2 kW of brake power instead of 55kW which is approx. 5.8% deviated from the rated value.

CONCLUSION:

An engine model for tractor applicataion has been constructed and the outputs were achieved with in permissible limits.
