An internal combustion engine and a method of operating said engine, the engine having a plurality of cylinders ( ) each respectively supporting a piston ( ) therein, a fuel injection system ( ) including a plurality of selectively operable delivery injector nozzles ( ), and a gas supply system ( ) for supplying gas to the delivery injector nozzles ( ), each delivery injector nozzle ( ) arranged to respectively deliver fuel by way of said gas directly into a said engine cylinder ( ), the method including opening the delivery injector nozzles ( ) of a first said cylinder and a second said cylinder such that gas within the first said cylinder is transferred through the delivery injector nozzle ( ) thereof and into the gas supply system ( ) resulting in gas being supplied to the delivery injector nozzle ( ) of the second said cylinder to thereby effect the delivery of fuel by way of the gas to the second said cylinder.

Start-up method for an internal combustion engine

A method of controlling an internal combustion engine during a warm-up period thereof including controlling at least one operational parameter of the engine as a function of at least a certain measure of the energy delivered to the engine since the start of the warm-up period of the engine to thereby provide improved combustion stability during said warm-up period. Preferably, the measure of the energy delivered to the engine is based on the amount of fuel delivered to the engine during the warm-up period.

Engine warm-up offsets

Regulation method for fuel injection system

An internal combustion engine is controlled during a warm-up period as a function of a cumulative measure of energy supplied to the engine. For example, the total amount of fuel delivered to the engine since start-up or an accumulated value of a load level of each combustion event during the warm-up period may be measured. A degree of offset or modification of individual engine operating parameters during the warm-up period may be based upon the cumulative measure of energy supplied to the engine.
