Filed:

Oct 14, 1982

Appl. No.:

6/434295

Inventors:

Noel G. Artman - Sun City AZ

International Classification:

F02B 2300

US Classification:

123263

Abstract:

Internal combustion reciprocating-piston engine precombustion chamber in which a mass of air or of air mixed with selective amounts of fuel and a spark-ignitable air-fuel mass are relatively segregatively compressed with the latter mass enveloping spark electrodes preparatory to ignition. The chamber is provided by recessing the air intake valve of an engine cylinder into the air intake passage for that cylinder so the chamber forms a section of that passage between the valve and the variable volume space above the piston in the cylinder. Contaminant products of combustion residual in the precombustion chamber upon completion of each combustion stroke are, during the next air intake stroke, vented into the cylinder variable volume space where they become mixed with the fresh intake air and any fuel entrained therein and then forced with this air back into the chamber pursuant to the ensuing compression stroke to be recycled during the next combustion stroke.

US Classification:

Abstract:

Stratified charge four-stroke-cycle internal combustion engine with fuel injection and spark-ignition of the type wherein stratification and initial combustion occurs in a combustion chamber auxiliary to the variable volume space in the engine cylinder between the piston and the cylinder head. Unique aspirating passage means communicating between the auxiliary chamber and the variable volume space conducts and causes air entering the chamber at one end, pursuant to the piston's compression stroke, to form a substantially non-turbulent air column rotating about the chamber axis and acretively compressed, by continued entry of air, toward and against the opposite end of the chamber. Fuel is injected into air initially in the chamber and that initially entering through the aspirating passage to mix with such air to form a spark-ignitable air-fuel mixture compressed against said other chamber end. The remaining air forced into the chamber pursuant to the compression stroke comprises a substantially discrete mass creating the desired compression of the chamber contents for spark-ignition and combustion of the fuel. After the combustion and exhaust cycles that sequentially follow ignition, there remains a residue of combustion products in the combustion chamber.

International Classification:

F02B 3100

US Classification:

123263

Abstract:

Internal combustion reciprocating-piston engine precombustion chamber in which a mass of air or air mixed with selective amounts of fuel and a spark-ignitable air-fuel mass are segregatively compressed with the latter mass enveloping spark electrodes preparatory to ignition. The chamber is provided by recessing the air intake valve of an engine cylinder into the cylinder head so that this chamber forms a section of the main air intake passage for the cylinder. Air deflecting means is provided in a vestibule of the chamber in a manner to create a vortex of air forced from the cylinder through the vestibule internally of the chamber pursuant to the compression stroke of the cylinder's piston, and, without incurring significant resistance to the flow of air delivered through the air intake passage into the cylinder pursuant to the preceding air intake stroke of the piston.

International Classification:

F02B 1908

US Classification:

123262

Abstract:

High-compression spark-ignited stratified-charge fuel-injection reciprocating-piston engine in which the combustion chamber initial charge includes a discrete air-fuel stratum that is lean with fuel at low speed idle and progressively increased in fuel richness and volume until that stratum ultimately completely fills the chamber with a homogeneous air-fuel mixture using all of the intaken air to attain maximum power. The combustion process minimizes pollutive exhaust emissions.

Inventors:

Noel G. Artman - Peoria AZ

International Classification:

F02B 1908

US Classification:

123262

Abstract:

Internal combustion stratified-charge engine having within a cylinder thereof a variable volume space wherein a piston pursuant to an air intake stroke draws a stream of intake air through an entrance end of the combustion chamber and through such chamber into said variable volume space. The inner periphery of a sidewall of such chamber having a series of grooves which may score the head of a poppet type exhaust valve in such periphery and which contribute to stratification of a leading fuel-free mass of such stream and a fuel-containing trailing mass thereof into the variable volume space. A portion of such trailing fuel-containing mass remaining in the chamber and an adjacent portion thereof in the variable volume space adjacent to said chamber, and, pursuant to the ensuing compression stroke of the piston, the masses are caused to flow into the chamber in the reverse order of their formation with the fuel-containing mass compressed adjacent the entrance end of the chamber where combustion is initiated.

International Classification:

F02B 300

US Classification:

123286

Abstract:

A spark-ignition type internal combustion engine having a precombustion chamber auxiliary to the variable volume space in the engine cylinder between the piston and cylinder head. Fuel injected into air in the chamber and fuel-laden air initially entering this chamber from the variable volume space, pursuant to the compression stroke of the piston, form a mixture compressed into a discrete reliably spark-ignitable air-fuel mass within a portion of the chamber where such mass envelops igniter electrodes. A vestibule portion of the chamber causes air, or air mixed with fuel in quantity deterninative of engine power output, forced from said space to enter the chamber in a manner compressing and retaining the air-fuel mass in its enveloping relation with the electrodes until ignition occurs.
