摘要： The invention relates to a device for dispensing a liquid gas formulation in a metered manner, wherein the device is particularly suited for use as an injection system in nail driving devices and comprises a pressure-stable container (1) having a flanged rim (2), to which a valve cover (3) containing a dispensing valve (4) is tightly fastened. The container (1) is equipped with two separated chambers (6,7), one of which receives the liquid gas formulation (F) and communicates with the dispensing valve (4) and the other of which contains a driving medium (L) under over-pressure. A piston (5), which can be moved in a sealing manner and which divides the container into the two chambers (6,7), is provided in the container (1). The driving medium (L) is compressed air in combination with a small amount of liquid gas formulation (F
ü ). The flanged rim (2) of the container (1) is designed as an inner flanging. The piston (5) is equipped with a one-way valve arrangement, which allows liquid gas formulation (F) to overflow from the chamber (6) containing the liquid gas formulation (F) into the chamber (7) containing the driving medium (L, F
ü ). The dispensing device is particularly inexpensive to design and can be cheaply produced and filled in a very simple manner.

摘要： This disclosure teaches a method of controlling a direct injection internal combustion engine and predicting the behaviour of a direct injection internal combustion engine. An estimation of initial cylinder pressure, air flow and EGR flow (if applicable) is used to establish a system that provides engine behaviour by integrating an injection module, combustion module and engine control module to provide data indicative of engine behaviour such as brake torque and power, air flow, EGR flow, cylinder pressure, brake specific fuel consumption, start of combustion, heat release rate, turbo-charger speed and other variables. These values can then be used to adjust commanded variables such as start of injection, commanded pulse width, rail pressure to meet operator demand. Also the output data can be used as a tool to determine how a conceptualised engine design will behave. This is particularly useful for gaseous-fuelled internal combustion engines where cylinder pressure influences behaviour of injected gases in light of the fact that rail pressure and cylinder pressure are, generally, of a similar magnitude.

摘要： The invention relates to a method of reducing emissions in the exhaust gases from an internal combustion engine (1) which comprises at least one cylinder (2) to which an air/fuel mixture is supplied when a crankshaft (3) of the internal combustion engine (1) is to be made to rotate, at least one inlet valve (4), at least one inlet duct (5) connecting to the inlet valve (4), at least one exhaust valve (6), at least one exhaust duct (5) connecting to the exhaust valve (4), control members (8) for controlling the opening and closing of the inlet and exhaust valves (4, 6), and a piston (10) reciprocating between a top dead-centre position and a bottom dead-centre position in the cylinder (2). The method comprises the following steps: a lean air/fuel mixture is supplied to the cylinder (2), the internal combustion engine (1) is controlled so that it works at high load, and the exhaust valve (4) is controlled so that it opens when the piston (10) is located in the bottom dead-centre position. The exhaust valve (6) is preferably controlled so that it closes after the induction stroke has started. According to one embodiment of the invention, the internal combustion engine (1) is controlled so that the crankshaft (3) rotates at an essentially constant speed within the range 1000 - 2000 rpm.

摘要： A method and apparatus is disclosed for adjusting pilot fuel injection timing in relation to a main fuel injection timing into a piston cylinder of an operating gaseous-fuelled direct injection internal combustion engine using high levels of EGR. A set of engine parameters are monitored which determine engine load and engine speed and an indicator of EGR concentration within the intake charge. Pilot fuel timing relative to main fuel injection timing is then adjusted according to the engine parameters. High levels of EGR are shown to be tolerated with relatively limited penalties in regards to other emissions typically found with high EGR by reducing the relative injection timing the pilot fuel as compared to main fuel injection timing.

摘要： In order to extent the operation range of an internal combustion engine, i.e. the operation range of a HCCI engine, or to increase the compression ratio of a spark ignition engine (Otto engine) the invention proposes generating a dual swirl in the cylinder. According to the invention the strength of the dual swirl is variable and adjustable or feedback controllable.
For the HCCI combustion mode the stratification of the temperature field is adjustable by the strength of the dual swirl flow motion which allows extending the operation towards higher engine loads. In addition, the dual swirl prevents the mixing of the gases in the two intake channels, which can be used to generate stratified mixtures without employing a direct injection system. This can be used for extending the HCCI operation range towards lower loads. In case of spark ignition engines the dual swirl can generate a more homogeneous temperature distribution allowing higher compression ratios and thus higher engine efficiencies.
摘要翻译：为了扩大内燃机的运行范围，即HCCI发动机的运行范围，或者为了提高火花点火式发动机（Otto发动机）的压缩比，本发明提出在汽缸中产生双重涡流。根据本发明，双涡流的强度是可变的和可调节的或反馈可控的。对于HCCI燃烧模式，温度场的分层可以通过双涡流运动的强度来调整，这允许将操作扩展到更高的发动机负荷。此外，双涡流防止两个进气通道中的气体的混合，其可用于产生分层混合物而不使用直接喷射系统。这可以用于将HCCI操作范围扩展到较低的负载。在火花点火发动机的情况下，双涡流可以产生更均匀的温度分布，允许更高的压缩比，从而提高发动机效率。

摘要： An improved method and apparatus for operating medium to high-speed four cycle compression ignition engines causes the amount of NOx in the exhaust gases to be reduced substantially. The four cycle compression ignition engine is of the type wherein fresh working fluid (64) is introduced through an intake valve (28), the working fluid is compressed, fuel is injected and burns thereby expanding the working fluid, and the working fluid is scavenged through an exhaust valve (30). The improvement comprises timing the opening of the intake valve and the closing of the exhaust valve so that no fresh working fluid is permitted to pass out the exhaust valve.
