Troubleshooting

SQUISH AREA

Rotax rotary valve engines incorporate a combus-
tion chamber which feature a squish area. This
area is basically a “ledge” projecting beyond com-
bustion chamber area. In operation, as the piston
ascends and approaches the ledge, a rapid
squeezing action is applied to the air / fuel mixture
contained in the area immediately between the
piston dome and the ledge. This squishing action
forces the entrapped mixture rapidly into the com-
bustion chamber area, creating a greater mixture
turbulence. Additionally, the small volume and
large surface area of the squish band allow a bet-
ter cooling of the end gases to help prevent deto-
nation.

CAUTION : When reassembling an en-
gine, always measure squish gap to make

sure it is within the specified tolerance.

1. Squish gap

If the squish gap is increased, a loss in power will
occur, while too small a squish gap will lead to
detonation.

Squish Gap Measurement

The squish gap can be measured by inserting a
piece of resin core solder into the combustion
chamber.

– Insert solder in combustion chamber.

– Rotate the engine through Top Dead Center ;

remove the solder and measure the thickness
of the compressed solder.

NOTE :

The solder should be inserted above

and in line with the wrist pin.

SYMPTOM

CAUSE

REMEDY

Engine revs 500 to
1000 RPM lower
than its maximum
operational
RPM ; RAVE valve
does not open at
all.

1. Bend valve rod Replace

2. Stuck valve

Clean

3. Wrong spring

tension (too
high)

Replace

4. Clogged pas-

sages

Clean

5. Damaged dia-

phragm

Replace

Engine hesitation.
Peak performance
is delayed until
higher RPM range
is reached. RAVE
valave opens too
early.

1. Broken or

weak spring

Replace

2. Adjustment

screw too far
out

Turn until it bot-
toms

3. Valve stuck

open

Clean
