System Features
• The VT 275 engine uses electro-
hydraulic injectors. The injectors use
lube oil under high-pressure to provide
the mechanical force needed to inject
fuel into the combustion chamber.
• The reservoir for the high-pressure pump
is cast into the front of the crankcase
Vee. The reservoir is supplied by the lube
oil pump and is used to provide a
constant supply of oil to the high-

• The high-pressure pump is mounted at
the rear of the crankcase Vee and is gear
driven off the rear gear train.
