3.2.2 Cold starter
The injection timing at cold start is made earlier
to improve startability.
The piston of the cold starter is operated by the
CSD solenoid valve depending upon the
temperature of cooling water for the engine,
thereby opening/closing the sub-port.
At hot start:
The sub-port is open and the plunger blocks the
sub-port. In this state, fuel starts being pumped.
Hot start assumes a temperature of about 5°C
minimum.

At cold start:
The sub-port is closed and the plunger blocks the
main port. In this state, fuel starts being pumped.
(At cold start, the fuel injection timing is
advanced.) Cold start assumes a temperature of
about 5°C maximum.
