The sketch shows a multi-cylinder engine cut open to reveal the inner components. Most of the candidates who attempted it did well by labelling the parts correctly. A few of the candidates, however confused the crankshaft with the camshaft.

The expected solutions are given below.

2.(a) The parts labelled are:

R - flywheel, S - piston, T - camshaft U - Connecting rod, V : Crankshaft, Crankweb or Web

(c)(i) Valve arrangement - overhead valve.
(ii)Cycle of operation - 4 stroke cycle.
(iii)Camshaft drive arrangement - belt drive
(iv)Type of lubrication - pressure feed or forced feed.
(v)Type of cooling - water cooling.
