Title:
RAIL PRESSURE OFFSET CONTROL METHOD AND COMMON RAIL TYPE FUEL INJECTION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2012021449
Kind Code:
A
Abstract:
To surely prevent the temperature of the fuel from exceeding the limit value on a component.
In the common rail type fuel injection control device constituted such that the target rail pressure is set higher than in the normal time in the range determined in advance where the engine rotational frequency is high when fully opening the acceleration, the target rail pressure is temporarily lowered (S108) and the careless raise of the temperature of fuel is suppressed when the operation condition of the engine 3 satisfies the predetermined condition causing the rise of the temperature of the fuel (104) and it is determined that the temperature of the fuel exceeds the predetermined limit value (S108).
