Definitions
- the object of the invention is a method of regulation parameters control in spark-ignition combustion -engine, in particular, the method of the ignition advance angle and the air excess ratio control, applicable to piston internal combustion engines fueled with waste energy products from technological processes, especially from chemical industry.
- waste energy products coming from the applied technological processes, are created.
- waste products generated in chemical industry technological processes seem to be particularly interesting.
- they are partially used in heating processes as an additive to the primary fuels.
- the waste gaseous products are burned burdening the environment with heat emission and emission of combustion products, and waste liquid products undergo costly utilization.
- Some of those substances can be used as fuels in internal combustion piston-engines.
- waste fuels obtained from technological processes usually do not retain repeatable quality.
- the waste fuels often come from a number of technological processes, and changes in parameters concern not only the chemical composition, but the volume of the available fuel stream whose value can change with time.
- a very important aspect in case of recuperation of flammable gas components are their thermodynamic properties which usually depend on the technological processes in which those fuels are created.
- fuels resulting from various technological processes are available within one industrial ' plant. Therefore, in order to use them rationally, they demand proper preparation, including drying and purification, and then mixing them in appropriate proportions and establishing desired thermodynamic properties.
- the above mentioned operations must be carried out with appropriate safety systems applied.
- the ignition- advance angle regulation system in internal combustion engine is known, operating according to adaptive principle wherein the ignition advance angle is adjusted based on the information retrieved from the engine combustion chamber, i.e. based on the occurrence of maximum pressure of the gases burnt in the cylinder.
- the timing advance adjustment system applied provides for maximum efficiency of the engine based only on standard, normalized fuels.
- the presented system is not suitable for the management of combustion process in an engine based on low-energy, variable waste fuels obtained from technological processes in chemical industry. Additionally, controlling only the ignition advance angle does not ' provide for maximum efficiency.
- PL2114378 discloses a method to manage, combustion process in a central heating boiler with automatic burner powered with solid fuel, wherein the fed fuel-air ratio is established based on the flue gas temperature.
- the presented method is not suitable for application in piston- engines, and the checking the exhaust temperature as such does not provide for reaching desired working conditions.
- the technical problem faced by the present invention is to offer a method to control variable parameters in a piston, multi-cylinder, internal combustion, spark-ignition engine in such a way that it enables the most favorable run of the combustion process, individually in each cylinder, and allows obtaining the maximum power or the maximum efficiency, or meeting the condition to reach the predetermined exhausts temperature value, while dynamically adjusting the ignition advance angle and the fuel dose (and by the same the air excess ratio) for each cylinder separately, relatively to the change in component and energetic properties of low-energy waste fuel obtained in chemical industry technological processes.
- the proposed invention comprises a non-standard method which unexpectedly solved all the mentioned technical problems .
- the object of the invention is a method to control variable parameters in internal ' combustion engine with spark-ignition, comprising both ignition advance angle and fuel dose control, characterized in that the temperature of exhausts is measured in the exhaust duct of each cylinder individually, and basing on the temperature measurement, the ignition advance angle and fuel dose are adjusted individually for each cylinder, wherein the adjustment of the fuel dose is effected by selecting the injector opening time, and - the ⁇ ignition advance angle adjustment is determined by the crankshaft rotation angle , wherein the value of the lyui un advance angle and the ' injector opening time are selected adaptively, individually for each cylinder, based on the temperature of exhausts in each exhaust duct, and the adaptation is carried out until reaching uniform temperature value in each cylinder.
- the key technical characteristic of the process is the possibility to select the ignition advance angle and fuel dose individually for each cylinder, particularly in multi-cylinder engine, due to the differences in fuel and air distribution for each cylinder relative to the change in load conditions and fuel properties.
- the adjustment of the fuel dose is effected by selecting the injector opening time, and the value of ignition advance angle is established by measuring the crankshaft rotation angle.
- the values of the ignition advance angle and the fuel dose can be selected individually for each cylinder collectively or separately, depending on the exhausts temperature measured individually in the exhaust duct of each cylinder, depending on the assumed criterion (e.g. power, efficiency, ecological requirements) .
- the value of ignition advance angle or injector opening time (fuel dose) are selected adaptively, individually for each cylinder, by a controller, based on the change in temperature of exhausts in each cylinder exhaust duct, depending on the assumed criterion.
- the adaptation consists in obtaining uniform exhausts temperature value in each cylinder, i.e. reaching a uniform working process in each cylinder, which results in reaching the predetermined criteria (e.g. power, efficiency, ecological requirements).
- the characteristic feature of the presented method is its effectiveness in relation to various types of gas and liquid fuels, which is not obvious for standard solutions.
- a method was achieved to control variable parameters in internal combustion engine with spark- ignition, comprising simultaneous control of the ignition advance angle and air excess ratio, wherein the temperature of exhaust gases is measured in the exhaust duct of each cylinder individually, and based on the temperature measurement, the ignition advance angle and the fuel dose are adjusted (thus affecting the air excess ratio) in order to maintain required working parameters of the engine, particularly on variation of energetic properties of the supplied waste fuel.
- the proposed method enables obtaining the most favorable combustion process, individually in each cylinder in a multi- cylinder internal combustion engine.
- the most favorable means here the criterion of reaching the highest power or the highest efficiency, or meeting the condition of reaching the predetermined exhausts temperature value, or meeting ecological requirements.
- the criterion allows to select the appropriate air excess ratio in the fuel-air mix feeding the engine, and to select the appropriate value of the ignition advance angle.
- Individual exhaust temperature measurement enables, within the predetermined criterion: reaching the maximum power or the maximum efficiency or meeting the condition to reach the predetermined exhausts temperature value, selection of the appropriate air excess ratio for the fuel-air mixture, and selection of the appropriate ignition advance angle value, individually in each cylinder, according to the customized temperature value measurement.
- Fig. 1 represents a block diagram illustrating the method to control variable parameters in an internal combustion engine with spark-ignition
- Fig. 2 represents the properties of the mixture for a MAN engine fueled with natural gas or hydrogen
- Fig. 3 represents exhaust temperature chart for a MAN engine fueled with natural gas or with hydrogen as the function of its power
- Fig. 4 represents general efficiency of a MAN engine fueled with natural gas .or hydrogen
- Fig. 5 represents the properties of the mixture for a bi-fuel MAN engine
- Fig. 6 represents exhaust temperature chart for a bi-fuel MAN engine
- Fig. 7 represents general efficiency of the bi-fuel . MAN engine.
- the basic technical characteristics of the engine are presented in Table 1.
- the practical embodiment of powering the above described engine with waste fuels from chemical industry required construction of a special fuel installation, separate for liquid and gas phases, with configuration in both cases similar to the Common Rail fuel supply system.
- the gas fuel supply system consisted of six fuel rail segments, each of which was equipped with two electronically controlled injectors 3, which facilitated precise control of the fuel dose depending on the engine load. While supplying fuel from chemical industry, spark plugs of NGG BCRE527Y type were used, wherein the spark duct was projecting further into the combustion chamber, which was particularly significant during fueling the engine with very lean mixture.
- a programmable engine controller was used, equipped with four knock sensors, which unambiguously determined the knock limit for each cylinder in all analyzed engine operating conditions. Additionally, the combustion flow in each cylinder was managed by thermocouples placed in the exhaust duct of each cylinder, directly at the exhaust outlet from the head.
- liquid phase consisted of a mixture comprising 50% of n- butanol and 50% of isobutanol.
- the fuel was given a working name of MIX.
