UNDERSTANDING

THE

DIESEL

••••

The

diesel

engine

closely

resembles

the

gasoline

engine

inasmuch

the

mechanism

essentially

the

same.

Its

cylinders

are

arranged

above

its

closed

crankcase;

its

crankshaft

the

same

general

type

that

gasoline

engine;

has

the

same

sort

valves,

camshaft,

pistons,

connecting

rods,

lubricating

system

and

reverse

and

reduction

gear.

Therefore,

follows

great

extent

that

diesel

engine

requires

the

same

preventative

maintenance

that

which

any

intelli-

gent

operator

would

give

The

are
