on appeal, is illustrative and reads as follows:
1. A two-cycle diesel engine for a vehicle, said engine
being comprised of a cylinder block containing at least one
cylinder bore closed at one end by a cylinder head and at the
other end by a crankcase member for forming a crankcase
chamber, a piston reciprocating in said cylinder bore, a
crankshaft journaled in said crankcase chamber, a connecting
rod connecting said piston to said crankshaft for driving said
crankshaft, an exhaust port formed in one side of said
cylinder bore and valved by the reciprocation of said piston,
and a precombustion chamber formed in said cylinder head on
said one side of said cylinder bore and communicating with a
main combustion chamber formed by said cylinder head, said
cylinder bore and said piston through a throat directed away
from said exhaust port, the direction of rotation of said
crankshaft being such that said piston tends to rotate about
its connection with said connecting rod in a direction during
the expansion stroke for moving the upper edge of said piston
into engagement with the side of said cylinder bore where said
exhaust port is formed.
