A fuel system comprises a fuel pump arranged to deliver fuel to a single fuel injector. The fuel pump and injector are physically spaced apart from one another, a high pressure fuel line being used to convey fuel between the fuel pump and the injector. The fuel pump is controllable to control the timing of commencement of fuel pressurization. The injector is controllable to control the timing of fuel delivery. A controller is arranged to control the operation of the fuel pump and the injector. The invention further relates to a fuel pump suitable for use in such a fuel system.

Fuel system and pump suitable for use therein

An engine system includes a compression ignition engine, a turbo-supercharger for supplying air under pressure to the engine, an intercooler disposed between the outlet of the compressor of the turbo-charger and the engine, an air heater the output of which is connected to the engine and a valve operable to cause the air from the compressor to be delivered through the intercooler or through the air heater to the engine. In addition the valve can be opened a small amount when it is required to initiate combustion in the air heater so that only a small flow of air takes place through the heater. When the combustion has started the valve is moved to the position in which all the air from the compressor of the turbo-charger flows to the engine through the air heater.
