摘要： Emission targets, such as NOx levels, for gaseous fuelled internal combustion engines that burn a gaseous fuel in a diffusion combustion mode are increasingly more challenging to achieve. A method of fuel injection for an internal combustion engine fuelled with a gaseous fuel comprises introducing a first amount of pilot fuel in a first stage of fuel injection; introducing a first amount of main fuel (the gaseous fuel) in a second stage of fuel injection; and introducing a second amount of main fuel in a third stage of fuel injection. The first and second amounts of main fuel contribute to load and speed demand of the internal combustion engine. Engine maps calibrated for different engine performance can be employed in different regions of the load and speed range of the engine. The engine maps are blended when the engine transitions between two regions; and momentary excursions into different regions do not change the engine calibration.

摘要： An internal combustion engine can be operated in an efficiency mode to provide a first power output range between zero and a transition power output level and in a power mode to provide a second power output range between the transition power output level and a maximum power output level. A first ignition timing and a first air/fuel ratio of the mixture can be used in the efficiency mode to avoid premature auto-ignition of a mixture of inlet air and a fuel according to an octane rating of the fuel and a compression ratio exceeding approximately 13:1. A second ignition timing and a second air/fuel ratio of the mixture can be used in the power mode to avoid premature auto-ignition of the mixture according to the octane rating of the fuel and the compression ratio exceeding approximately 13: 1. To further enable knock free operation of such an engine, turbulence can be imparted to the mixture to promote a faster burn duration and high temperatures that may lead to premature auto-ignition of the mixture can be avoided.

摘要： In an embodiment, the invention provides an internal combustion engine, including a first fuel injector (11) that supplies a first fuel to a first predetermined region in a combustion chamber (1), and a second fuel injector (12) that supplies a second fuel to a second predetermined region in the combustion chamber (1). The second fuel has an octane number that is different than an octane number of the first fuel, and the second predetermined region is different from the first predetermined region. An ignition device is configured to start ignition of one of the first and second fuels based on an ignition signal. An operation condition detector detects at least one engine operating condition. A controller (50) is configured to provide the ignition signal to the ignition device and to determine which one of the first and second fuels to ignite by the ignition device based on the engine operation condition.

摘要： At each engine cycle, nearby the TDCC an injector is driven so as to perform a fuel injection sequence according to a predetermined pattern (A-Z), including a plurality of successive, separate fuel injection pulses (pulse 1 - pulse N) having respective predetermined durations. The start of the first injection pulse (Pulse 1) of the sequence is defined as a predetermined angular distance from the TDCC. For each injection pulse (pulse 2 - pulse N) following the first one (pulse 1) the respective start is selectively determined either as a time distance from the end of the immediately preceding injection pulse (pulse 1 - pulse N-1) or as an angular distance from the relevant TDCC, in dependence on the instantaneous value of at least one predetermined parameter.

摘要： In a fuel supply apparatus for an internal combustion engine including a first fuel injection valve for directly injecting a fuel into a cylinder and a second fuel injection valve for injecting the fuel into an intake manifold, production of deposits in the first fuel injection valve is prevented and a satisfactory homogenous air-fuel mixture can be formed during homogenous combustion while an engine is idle. In order to achieve this effect, during homogenous combustion while the engine is idle, a second fuel injection valve (12) injects the fuel and a first fuel injection valve (11) injects the fuel to which pressure has been applied by a low-pressure pump (21), without a high-pressure pump (23) applying further pressure to the fuel.
