Lubricating system.
The system is of combination (splash-and-force) type: bearings of crankshaft, camshaft and
accessory drive shaft are force-lubricated; cylinders, valve gear and its drive are splash-
lubricated, A gear oil pump with an oil intake strainer and a reducing valve in the cover is
located in the engine sump. A quick-change full flow oil filter has a filter element made of
special cardboard.
Fuel system.
An emulsion type, two barrel, down draft carburettor has a pneumatically controlled
secondary throttle, balanced float chamber, crankcase fume recirculation system,
pneumatically controlled economiser, diaphragm type acceleration pump, independent idling
system and a gauze filter at fuel inlet; the choke is fitted with a diaphragm mechanism for cold
engine starting. An air cleaner is fitted with a replaceable element made of special cardboard
and a synthetic wool pre-cleaner. An additional oil bath air cleaner is installed to special order.
A diaphragm type fuel pump is provided with a gauze filter and a hand priming lever.
Crankcase breathing system.
The system is closed type, with an oil separator and a flame arrester.
Cooling system.
The system is sealed, liquid type with a translucent expansion tank. A solid filled thermostat
in a one piece housing is hose connected to the cooling system. A six blade plastic fan fitted on
the centrifugal water pump shaft is driven by a V-belt from the crankshaft pulley.
Ignition system.
The system is battery operated, with a rated voltage of 12 V. The ignition distributor is
provided with centrifugal and vacuum spark timers driven from the accessory drive shaft.
Ignition coil B-117 or B-117A has no series resistor. Spark plugs A17L~B, FE65P and high
tension wires with resistors suppressors in the boots or high tension wires FE65CPR with
built in resistors suppressors and high tension wires without the resistors suppressors in the
boots. The spark plugs have thread MCO M14X1.256E and 19mm reach. The initial spark
advance angle is set by marks on the crankshaft pulley and timing gear cover.
Exhaust system.
The system is provided with two successively mounted mufflers, with the tail exhaust pipe
at the car rear. To special order the exhaust system is equipped with an exhaust gas
recirculation system.
