Title: Quick preheating device for diesel engine
Inventor: KOYAMA TAKAYASU
IPC: F02B3/06
Filed: 1986-03-06
Abstract: PURPOSE:To improve a starting property by preventing the supply of a large current to a glow plug based on an engine speed and an increased engine speed within a defined period of time. CONSTITUTION:When the engine speed of a Diesel engine 1 which is obtained by the output of a revolution sensor 28 becomes above a defined engine speed in the revolution detecting circuit 48 of a preheating control circuit 10, or when the increased amount of the engine speed during the cooling time of a glow plug 4 obtained from the revolution sensor 28 and a counter 45 is above a defined value in an increased revolution detecting circuit 50, a signal which is inverted to a low level is outputted to one of the input of a three-input NOR gate 47. Thereby, the output of the three-input NOR gate 47 becomes a high level, without carrying out the supply of a large current to the glow plug 4 via the contact 7a of a main relay 7. Accordingly, the glow plug 4 is prevented from being electrified under a condition that the Diesel engine 1 is about to be started, preventing the lowering of the voltage of a starter 24.

Abstract: PURPOSE:To prevent the deformation and heating damage of the parts around an ultrasonic vibrator, by imparting tension force to the lead wire of the ultrasonic vibrator within the tolerant range of the tensile strength of said lead wire by the elastomer attached to an ultrasonic vibrator driving circuit. CONSTITUTION:A spring 13 is provided to an ultrasonic vibrator driving circuit 11 and tension force is imparted to the lead wire 3 of an ultrasonic vibrator 1 within a range of the tensile strength of said lead wire 3.

Abstract: PURPOSE:To enhance the response of a valve body when the valve mouth is to be opened, by furnishing the valve body, which is operated by an electric magnet so as to open and close valve mouth, with a permanent magnet which is attracted to the electric magnet, when the valve mouth is shut, and is separated from the electric magnet when the valve mouth is opened. CONSTITUTION:When an electric magnet 9 is controlled so that No.2 core 33b and a permanent magnet 39 repulse each other and that No.1 core 33a and the permanent magnet 39 attract each other, a valve body 38 retracts from a valve mouth 28, and inside a compartment 17 is decompressed rapidly. Therefore, the valve body 13 of injection valve is retracted by the pressure of the fuel in a pressure accumulator chamber 7, and a fuel jet 2 is opened. The magnetic repulsive force generated at this time between the permanent magnet 39 and No.2 core 33b becomes smaller as the valve body 38 goes apart from the valve mouth 28. Accordingly the valve body 38 and permanent magnet 39 at a standstill can be moved momentarily by a large force to open the valve mouth 28, which should enhance the response of the valve body 38.

Abstract: PURPOSE:To prevent the cell temperature from dropping than a specified heat retaining temperature of the cell and to prevent the deterioration in cell performance caused by change in electrolyte quality by circulating a heating medium in a bypass instead of a cell until the temperature of the heating medium becomes higher than a specified heat retaining temperature of a cell at the start of operation. CONSTITUTION:A bypass 6 connecting between an inlet pipe 5 and an outlet pipe 5' for a heating medium and change-over valves 7, 7' and 8 which operate the bypass 6 are arranged. Cell temperature t and heating medium temperature t' in a circulation path are detected with temperature detectors 9, 10 respectively, and detected signals are inputted in a controller 11 and compared to control the valves 7, 7'. At the start of operation, since the inlet valve 7 and the outlet valve 7' are closed and the bypass valve 8 is opened, the heating medium is circulated through the bypass instead of a cell. When the heating medium temperature becomes equal to or higher than a specified cell temperature, valves 7, 7' are opened and the bypass valve 8 is closed by the output signal from the controller 11, and the temperature is increased by the heating medium circulating in the cell.
