Improvement of Heat Flux Measurement on Combustion Chamber of Spark Ignition Engine (Conditions on Combination of Composite Materials in Thin Film Type of Heat Flux Sensor)
Autor: Hidenori Tasaka, Yoshinori Nagase
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 73:1753-1758
It is important to measure heat flux from the burnt gas to the combustion chamber because of the improvement of the efficiency of an engine. Instantaneous heat flux of S. I. Engine is usually measured using a thin film type of heat flux sensor. But t

Relationship between Gas Flow and Flame Shape for Premixture Combustion using Constant Volume Combustion Chamber
Autor: Shigeki Tomomatsu, Hidenori Tasaka
Publikováno v: Journal of The Japan Institute of Marine Engineering. 41:761-767
Premixture combustion mainly occurs in gasoline engines but it had also occurred in diesel engines at the previous combustion. Gasoline engines have been used as marine engines especially for pleasure boats. The mechanism of premixture combustion hel

Extraction Method and Evaluation of Shape for Flame Cross Section of Premixed Turbulent Combustion in Constant Volume Combustion Chamber by Image Measurement
Autor: Hidenori Tasaka, Shigeki Tomomatsu
Publikováno v: Journal of The Japan Institute of Marine Engineering. 41:920-927
To clarify the mechanism of turbulent combustion from a view point of physical data, premixed turbulent combustion in a constant volume combustion chamber was researched. Flame shape was measured as cross sectional image by laser sheet method. The mo

Examination of LDV Using Laser Diode and Measurement Example of In-Cylinder Flow of an Engine
Autor: Yoshinori Nagase, Shigeki Tomomatsu, Gou Ohara, Hidenori Tasaka
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 70:1086-1091
Laser Doppler Velocimeter (LDV) is one of the most useful method to measure the flow velocity of fluid flow such as swirl velocity in an engine. The laser as the light source of LDV has been usually used high power gas laser because of the weak scatt

Experimental Study of Heat Transfer Coefficient in a Spark Ignition Engine. 2nd Report. Examination of arrangement of heat transfer coefficient under motored conditions
Autor: Hiroshi Tajima, Hidenori Tasaka
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 63:2228-2232
Many studies have been conducted on heat flux or the heat transfer coefficient in an engine in order to increase thermal efficiency and to solve thermal loading problems. The authors showed the relation between Re number and Nu number at near TDC und

Experimental Study of Heat Transfer Coefficient in a Spark Ignition Engine. 1st Report. Relation between gas velocity and heat transfer coefficient under motored conditions
Autor: Hiroshi Tajima, Hidenori Tasaka
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 62:2902-2906
Many studies have been made on heat flux or heat transfer coefficient in internal combustion engines to increase thermal efficiency or to solve thermal loading problems. However, there are few cases in which heat flux of engine walls and gas velocity

Capability of In-Cylinder Flow Measurements by Backward Scattered LDV Using Low Power Laser
Autor: Kazuyuki Shiiba, Hidenori Tasaka
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 60:1822-1826
Many pepers have been published on the measurements of in-cylinder flow of an engine, because flow velocity affects to heat transfer to the cylinder walls, and the turbulence intensity also affects the combustibility of the fuel air mixture. Backward

Prediction of Swirl Velocity of In-Cylinder Flow of an Engine by a Simplified Simulation Model. 4th Report, Evaluation of Valve Timing
Autor: Hiroshi Tajima, Hidenori Tasaka, Yoshinori Nagase
Publikováno v: TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B. 59:2090-2093
Improving combustion of the spark ignition engines contributes largely to decreasing fuel consumption, especially under the conditions of medium or low speed and low load. In this paper, valve timing is evaluated from the viewpoints of swirl velocity
