Title: Cleaning method for combustion chamber of diesel engine
Inventor: SUZUKI AKIRA
IPC: F02B77/04
Filed: 1980-04-14
Abstract: PURPOSE:To improve the durability of the member of the combustion chamber by a method wherein high-pressure air in a starting air tank is jetted into the combustion  chamber near the top dead point of a piston at which an exhaust valve is opened  and thereby stains stuck to the surface of the member of the combustion chamber  are blown off and discharged together with burnt gas. CONSTITUTION:In the starting system of the diesel engine, starting is conducted in such a manner that, by injecting high-pressure air from the starting air tank 5 into the combustion chamber 8 through a starting valve 7, the piston 9 is pushed down to give a rotational force to a crank to start its motion and that when the prescribed rotational number or more is reached fuel 12 from a fuel pump 11 is supplied to an injection valve 13. In the aforesaid constitution, the high-pressure air in the starting air tank 5 is made capable of being supplied to the starting valve 7 through the intermediary of a cleaning-air controlling valve 19 provided separately. From this starting valve 7, the high-pressure air 6 is jetted into the combustion chamber 8 wherein pressure is turned low by the opening of the exhaust valve 16, near the top dead point of the piston, and thereby the stains stuck to the surface of the member of the combustion chamber are blown off and discharged from the exhaust valve 16.

Concretely speaking, PID information is reproduced, for example, by one block (16 sectors), and a detection method (the differential or sum signal) where the number of readable sectors is larger is selected. The selection is executed by a control circuit 6, and a control signal according to the result is inputted into the switch-over circuit of a reproduction circuit 9.

Abstract: PROBLEM TO BE SOLVED: To continuously monitor a specific gas in the passive measurement system day and night by performing the spectral measurement of the characteristic absorption wavelength band of gas to be measured in addition to the measurement of a two-wavelength band and monitoring the change in all signals with time. SOLUTION: A temperature band infrared ray detection system for measuring temperature TO in an observation visual field by measuring the characteristic absorption wavelength band of a carbon gas existing in the atmosphere uniformly is added, a heat infrared radiation equivalent temperature Ti on the surface of a heat infrared ray radiation object in the observation visual field is compared with an air temperature TO, and the visual field of a sensor is scanned, thus setting the visual field to a heat infrared ray radiation surface with a sufficient temperature difference.  In this case, when a heat infrared radiation equivalent temperature Tg of the gas to be measured is nearly equal to the air temperature TO, the temperature difference between the heat infrared radiation equivalent temperature Tg of the gas to be measured and TI can be fully secured if the temperature difference between the air temperature TO and TI is sufficient. Also, even if the heat infrared radiation equivalent temperature Tg of the gas to be measured differs from TO, the atmosphere is mixed with the gas to be measured and TO changes, thus detecting the gas to be measured by comparison even if the change in the signal with time is considered.
