Title: Fuel temperature control device for internal combustion engine
Inventor: KANEKO TOMOHIRO
IPC: F02M31/16
Filed: 1998-05-27
Abstract: PROBLEM TO BE SOLVED: To speedily elevate fuel temperature when the fuel temperature is low due to, for example, cold starting of an engine, and improve controllability of the fuel temperature. SOLUTION: In this device, a part of fuel press-fed from a fuel press-feeding pump 1 to a common rail 2 is introduced into a pressure accumulator chamber 9 having capacity smaller tan that of the common rail 2. The fuel is then speedily boosted and increased in temperature. The fuel of high temperature is press- fed again to the common rail by the fuel press-feeding pump. Inflow and discharge of fuel to the pressure accumulator chamber is carried out by opening and closing solenoid valves 8, 10 arranged on upstream and downstream sides of the pressure accumulator chamber by means of an ECU 14.

Abstract: PURPOSE:To enable the inspection of a true moisture resistance level, by providing a prelinary chamber equipped with heating and cooling mechanisms for shielding a sample from outside air at the front stage of a test chamber to prevent water drops from attaching to the sample depending on differences in the temperature and humidity. CONSTITUTION:A pretest chamber 13 equipped with a heating heater 4a, a humidifying heater 3a and a cooling mechanism 12 is built as connected to a test chamber 5 separated with a shielding door 14. In such an arrangment, a test sample 6 is placed into the pretest chamber 13 maintained in a room atmosphere and the chamber 5 is set equal in the temperature and humidity conditions to it. Then, the door 14 is opened to put the sample 6 into the chamber 5 with a push bar 15 and then, it 14 is closed. To withdraw the sample, the heaters 3a and 4a and the cooling machanism 12 are controlled to make the conditions of the pretest chamber 13 equal to the chamber 5 and then, the door 14 is opened to take it 6 out to the chamber 13, whose atmosphere is made equal to that in the chamber 13 for withdrawal. Thus, the carry in and out of the sample 6 is done under the environmental conditions the same between the chambers. This prevents attaching of water drops to the sample thereby enabling the inspection of true moisture resistance level regardless of the frequency of opening or closing the chambers.

A control code is detected from this signal by the circuit 8 to discriminate the recording state. By this method, after a DC potential fluctuation of a signal to be supplied from the demodulator 5 to the converter 11 is stabilized, the presence of the control code is decided, and hence the accurate reproducing can be performed.
