IGNITION-ASSISTED FUEL COMBUSTION SYSTEM

Abstract of the Disclosure Ignition-Assisted Fuel Combustion System Conventional direct injection internal combustion engines will not completely ignite and burn relatively lower-cetane-number fuels such as 100 percent methanol or ethanol because the fuel spray injection pattern usually cannot carry or propagate a flame to all the injected fuel which is typically made up of individual fuel streams which are separated by pockets of fuel-deficient intake air. The present fuel combustion system includes a fuel ignition-initiating device such as a glow plug and apparatus for interconnectedly contacting and continuously bridging all of the individual fuel streams with an auxiliary cloud of well-atomized fuel. In this manner, a flame initiated by the fuel ignition-initiating device is rapidly and completely propagated via the auxiliary cloud of fuel to all the individual fuel streams.

COMPRESSION-IGNITION ENGINES

A compression-ignition engine and a method for operating a compression ignition engine in which a mixture of air and methanol is provided in the combustion space. A pilot amount of diesel fuel is injected into the at least partially compressed mixture to start combustion. The temperature of the air or the air/methanol mixture is raised prior to compression by at least 25.degree.C by preheating with waste heat from the engine. A cetane improver is also incorporated in the diesel fuel.

FOUR-CYCLE INTERNAL COMBUSTION ENGINE WITH CURTAILED INTAKE PROCESS

A four-cycle internal combustion engine has a permanent curtailed intake process, which allows the temperature and pressure of intake air to the combustion cylinders to be tightly controlled, and enables a very small combustion chamber so that a much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the air/fuel mixture auto-ignition threshold. The maximum threshold of curtailed intake volume is determined to be 68% of engine cylinder volume to achieve a compression ratio CR of 18 or higher. Because this design can effectively regulate and set the maximum pre-ignition temperature of the fuel-air mixture, it can combust virtually any type of liquid hydrocarbon fuel without knocking. This four-cycle engine, due to its higher compression ratio, generates power equivalent to or greater than a standard four-cycle engine in a smaller and lighter engine and at a much higher efficiency.

Method for operating an injection valve of an internal combustion engine

A method for operating an injection valve of an internal combustion engine, whereby the metering of fuel is adjustable in particular by varying the stroke of the nozzle needle of the injection valve, makes it possible to prevent an incomplete closure of the valve due to soiling (the risk of damage caused by a gasoline-filled cylinder) in operating states of the internal combustion engine in which no complete strokes of the nozzle needle occur over a prolonged period of time and the nozzle is therefore not sufficiently scavenged. The nozzle is scavenged with fuel when a jammed-open operating state of the nozzle needle is detected.

FIELD: engines and pumps.SUBSTANCE: essence of the invention consists in the fact that the four-stroke internal combustion engine with spark ignition (SI) carries out the process of the constantly shortened inlet that allows temperature and pressure of the sucked air in the combustion cylinders to be under strict control, and provides the possibility of operation with a very small combustion chamber, so that much higher compression ratio and pre-ignition compression pressure can be achieved without approaching the auto-ignition threshold of the air-fuel mixture. Maximum threshold of the volume of the reduced intake makes 68 % of the volume of the engine cylinder in order to achieve the degree of compression of the CC equal to 22.1 or higher. Since this design allows effective control and setting of maximum temperature of preliminary ignition of air-fuel mixture, engine can operate on virtually any type of liquid hydrocarbon fuel without knocking.

Die Erfindung betrifft ein Verfahren zum Betreiben eines Einspritzventils einer Brennkraftmaschine, wobei die Dosierung der Kraftstoffmenge insbesondere durch eine Variation des Hubs der Düsennadel des Einspritzventils einstellbar ist. Derartige Verfahren und Einspritzventile sind im Stand der Technik grundsätzlich bekannt. Zur Vermeidung der Gefahr eines unvollständigen Schließens aufgrund von Verschmutzung (Gefahr eines Benzinschlags) bei Betriebszuständen der Brennkraftmaschine, bei denen über längere Zeit kein Vollhub der Düsennadel und damit auch keine ausreichende Spülung der Düse durchgeführt wird, wird erfindungsgemäß vorgeschlagen, eine Spülung der Düse mit Kraftstoff dann durchzuführen, wenn ein offen klemmender Betriebszustand der Düsennadel erkannt wurde.

Patent FR2343893B1

Engine control system

Disclosed is an engine control system which is designed to allow homogeneous-charge compression ignition combustion to be performed in an HCCI region (R) defined as an engine operating region including at least a partial-load range of an engine. In a low load zone (R1) of the HCCI region (R), a lift amount of an intake valve (11) is set to a first predetermined value, and an exhaust valve (12) is allowed to start being opened during an intake stroke at a given timing later than an opening timing of the intake valve (11). Further, in the medium load zone of the HCCI region, the lift amount of the intake valve (11) is gradually increased up to a second predetermined value greater than the first predetermined value, along with an increase in an engine load. The engine control system is capable of adequately controlling an amount of burned gas to be introduced into a cylinder, depending on the engine load to allow the HCCI combustion to be adequately performed in a wider engine load range.

Method for modeling combustion process of internal combustion engine operating on Otto principle, involves modeling combustion process by superposition of two vibe-functions

The method involves modeling a combustion process by a superposition (1) of two vibe-functions (3,5). The premixed area of the combustion is simulated by the former vibe-function. The diffusion-controlled area is simulated by the later vibe-function. A vibe-parameter of the former vibe-function and a vibe-parameter of the later vibe-function are independent from each other.

Patent DE2831442C2

Cold starting system for alcohol fueled engine

To start an ethanol fueled engine at low temperatures, a valve directs liquid ethanol from the carburetor accelerator pump to a PTC thermistor grid disposed in the engine induction passage below the throttle. The electric grid evaporates the liquid ethanol to provide sufficient ethanol vapor to start the engine and then is deenergized when the engine has started.

High efficiency internal combustion steam engine

An internal combustion steam engine is operated with an alcohol-water fuel mixture vaporized prior to combustion by heated engine coolant that flows through a first heat exchanger (18). The first heat exchanger or vapor generator (18) uses the waste heat from the engine coolant to heat and vaporize the alcoholwater mixture. A second heat exchanger (60) using exhaust gases heats the combustion air before passage through the intake manifold (46). Complete vaporization of the alcohol fuel is accomplished to overcome the lower caloric power potential of alcohol as compared to gasoline and to insure complete and regular combustion.

Method for operating an injection valve of an internal combustion engine

The invention relates to a method for operating an injection valve of an internal combustion engine, whereby fuel dosage is adjusted especially by a variation of the stroke of the injector pin of the injection valve. Generic methods and injections valves are generally known from the prior art. The aim of the invention is to provide a method which makes it possible to avoid an incomplete closure of the valve due to soiling (danger of a damage caused by a gasoline-filled crankcase) at operating states of the internal combustion engine where no complete stroke of the injector pin occurs over a prolonged period of time and the nozzle is therefore not sufficiently scavenged. According to the invention, the nozzle is scavenged with fuel when an open jamming operating state of the injector pin is detected.

Mixture-warming device for a two-stroke internal combustion engine using a lower quality fuel

Several embodiments of heating devices for heating the charge of a two-cycle engine before it passes the gap of the spark plug at the time of ignition. The heating devices permit the use of low quality fuel such as kerosene or alcohol without some of the problems normally attendant with engines running on this type of fuel.
