Engine combustion control at low loads via fuel reactivity stratification

A compression ignition (diesel) engine uses two or more fuel charges during a combustion cycle, with the fuel charges having two or more reactivities (e.g., different cetane numbers), in order to control the timing and duration of combustion. By appropriately choosing the reactivities of the charges, their relative amounts, and their timing, combustion can be tailored to achieve optimal power output (and thus fuel efficiency), at controlled temperatures (and thus controlled NOx), and with controlled equivalence ratios (and thus controlled soot). At low load and no load (idling) conditions, the aforementioned results are attained by restricting airflow to the combustion chamber during the intake stroke (as by throttling the incoming air at or prior to the combustion chamber's intake port) so that the cylinder air pressure is below ambient pressure at the start of the compression stroke.

Internal combustion engine with a valve system for operation in two-stroke or four-stroke mode

The invention concerns an internal combustion engine which comprises at least two opposite working cylinders between which a boost cylinder is disposed. The working cylinders accommodate reciprocating working pistons which are rigidly connected to a boost piston which moves in a reciprocating manner in the boost cylinder and divides the latter into two boost cylinder chambers. The internal combustion engine further comprises an output shaft, driven by a crank mechanism, and a valve system for the intake and discharge of fresh gas and exhaust gas, respectively. The valve system is formed by at least one roller valve (13, 14) and, per working cylinder (1, 2, 3, 4), at least one each of a pneumatic fresh gas valve (19, 20, 21, 22) and an exhaust gas or flush gas valve (15, 16, 17, 18). The compressed fresh gas, which passes through the roller valve (13, 14) in a timed manner adapted to the movements of the working pistons (5, 6, 7, 8) via the fresh gas lines (23, 24) to the pneumatic fresh gas valve (19, 20, 21, 22) and exhaust or flush gas valves (15, 16, 17, 18), opens the latter owing to its pressure and flows into the combustion chambers of the working cylinders (1, 2, 3, 4).

Four-cycle internal combustion engines with two-cycle compression release braking

An internal combustion engine has engine cylinder intake and exhaust valves that are operated by intake and exhaust cams via hydraulic linkages. The hydraulic linkages have selective lost motions that allow selective modification of the openings and closings of the engine cylinder valves. These modifications may also include complete omission of all response to particular lobes on the cams. The hydraulic linkages may be interconnected so that some intake valve openings are produced by an exhaust cam lobe and/or some exhaust valve openings are produced by an intake cam lobe. The linkages and linkage interconnections are preferably controlled electronically. The engine is preferably operable in either four-cycle positive power mode or two-cycle compression release engine braking mode. The intake cam may have plural lobes or only one lobe, while the exhaust cam may only have one lobe.

Combustion control method and system in natural gas engine

FIELD: engine building.SUBSTANCE: invention can be used in engines operating on natural gas. Method for controlling combustion in an engine on natural gas comprises determining, on the basis of the current operating parameter of the engine on natural gas, the operating state of the engine. Number of full injection of natural gas and pilot diesel fuel required by engine in this operating condition is calculated. Diffusion combustion mode with direct injection is performed in case operating state is idle or low load state. Diffusion combustion mode with direct injection is a mode in which diesel fuel is injected at a top dead compression point and then injecting natural gas. Compression ignition mode is performed with active control of hybrid homogeneous natural gas in case when working state is average load condition. Compression ignition mode with active homogeneous natural gas control is a mode in which natural gas is injected after closing the inlet valve, and diesel fuel is injected at the moment to upper compression dead point. Total injection amount is divided into three parts including amount of natural gas injection at compression ignition, the amount of pilot diesel fuel injection and the amount of natural gas injection during diffusion combustion, in the case when the working state is a high load condition. Natural gas is injected in amount of natural gas injection at compression ignition into combustion chamber so that it is mixed with air inside combustion chamber at early stage of engine compression stroke on natural gas. Injection, at moment near upper dead point of compression or at large angle of advance of injection of diesel fuel, diesel fuel in amount of pilot diesel fuel injection into combustion chamber in order to ignite pre-injected natural gas. Natural gas is injected after preset time interval in amount of natural gas injection at diffusion combustion into combustion chamber. This early stage of compression stroke begins from the moment of ...

Method of supply of internal combustion engine

FIELD: mechanical engineering; supply systems of internal combustion engines. SUBSTANCE: gaseous fuel in liquid phase is taken form gaseous fuel supply source and is delivered into engine supply system. Gaseous fuel is subjected to cleaning in multistage filter and than is heated in evaporator to converter it into new consistent state, is reduced and delivered under pressure into intake manifold thus providing effect of supercharging and complete combustion of double fuel mixture. At idling, gas is supplied into idle system of carburetor without liquid fuel which considerably reduces toxicity of exhaust gases at idling. Sharp reduction of toxicity of exhaust gases and considerable (up to 50%) economy of liquid fuel is provided owing to enrichment of liquid fuel-air mixture and delivering the mixture into intake manifold through atomizer in minimum amounts sufficient for starting and operating the engine.

Patent DE170203C

Improvements in or relating to internal combustion engines

一种内燃发动机，其每个汽缸连接一个空气源和一个带有压力燃气的燃料源。在压缩冲程中，全部的空气进气被抽吸和压缩，这一过程在供料进入且混合气点燃以便开始随后的作功冲程之前基本完成。燃料可通过一燃气进气阀和点火器的组件进入气缸。现有的汽油和柴油发动机喷油器孔和火花塞孔可被设计用于装配这种组件。压缩了的气态燃料可以是甲烷或其他天燃燃气。本发明包括固定式和可移动或发动机，特别是汽车发动机以及操作它们的方法。
