<p>An internal combustion engine includes a compressor (23) to supply pressurised gas to effect injection of fuel for combustion in the engine. An intake system (17, 18, 19) includes a throttling assembly (19) to control the flow of air through the intake system. A gas inlet port to the compressor (23) is connected (31) to the air intake system (17, 18, 19) downstream of the throttling assembly (19). This lowers the pressure at the inlet port of the compressor (23) to below ambient air pressure. A method of operating an internal combustion engine of this type includes the step of lowering the pressure at the inlet port to the compressor (23) to below ambient air pressure.</p> |
