Abstract
Sposób pomiaru całkowitego pola przekrojów przecieków komory roboczej zwłaszcza tłokowego silnika spalinowego, charakteryzujący się tym, że dla badanej komory określa się w milimetrach kwadratowych wartość graniczną sumarycznego pola przekrojów przecieków gazu między tłokiem i cylindrem, następnie w urządzeniu składającym się z czterech wymiennych dysz (4, 5, 6, 7) manometru różnicowego i zaworu pomiarowego dobiera się dysze o średnicy wewnętrznej większej od pierwiastka z wartości granicznej sumarycznego pola przekrojów przecieków i urządzenie z tak dobranymi dyszami łączy się najpierw dyszą pomiarową poprzez uchwyt mocujący i otwór z wnętrzem komory roboczej, a następnie przewodem poprzez zawór redukcyjny i filtr ze źródłem sprężonego powietrza, po ustaleniu się przepływu powietrza przez komorę roboczą pokręcając bębnem zaworu pomiarowego doprowadza się do zerowego wskazania na manometrze różnicowym i przy zerowym wskazaniu na manometrze dokonuje się z podziałki na bębnie i podziałki na dyszy odczytu odległości S płytki zaworu pomiarowego od czoła dyszy pomiarowej i oblicza w milimetrach kwadratowych rzeczywistą wartość sumarycznego pola przekrojów przecieków.The method of measuring the total leakage cross-sectional area of the working chamber, especially the piston internal combustion engine, characterized by the fact that the limit value of the total cross-sectional area of gas leakages between the piston and the cylinder is determined in square millimeters for the tested chamber, then in a device consisting of four interchangeable nozzles (4, 5, 6, 7) of the differential pressure gauge and measuring valve, the nozzles with an internal diameter greater than the root are selected from the limit value of the total leakage cross-sectional area and the device with nozzles selected in this way is first connected with the measuring nozzle through the mounting holder and the opening to the inside of the working chamber, and then through the conduit through the reduction valve and the filter with the source of compressed air, after establishing the air flow through the working chamber, turning the measuring valve drum brings the zero indication on the differential manometer and at the zero indication on the manometer, the scale on the drum and scale are made on the nozzle, read the distance S of the measuring valve plate from the face of the measuring nozzle and calculate in square millimeters the actual value of the sum of the leakage cross-sections.
