Filed: 1982-03-23
Abstract: PURPOSE:To enable an intake apparatus of an engine to accord with both low and high speed operations by arranging an intake port for generating a strong vortex and an intake port for generating a weak vortex to eliminate a port opening/closing valve. CONSTITUTION:A mixed gas is introduced through intake valves 24 and 25 from intake ports 18 and 20 at the intake stroke where a piston lowers as indicated by the broken line and the solid line. A vortex S1 as indicated by the solid line and that S2 by the broken line are formed centered on points A and B on both sides of the center line X-X of the cylinder in such a manner as not to interfer with each other. This leaves a strong vortex immediately before the end of the compression stroke where the piston rises thereby providing a strong torque at the low speed of the engine with a better combustion. On the other hand, in the operation at the high speed, an intake port 20 for generating a weak vortex introduces an ample amount of intake air to a combustion chamber without lowering the intake efficiency a bit.

Abstract: PURPOSE: To hold temperature of a glow plug to preset temperature, by allowing a timer, provided with a triggering short time, to electric conduction control the glow plug when temperature, detected from the glow plug that causes electromotive force at its nonconduction, reaches not more than prescribed temperature.  
     CONSTITUTION: When a key switch S is closed, electric conduction is caused with the first timer 1 to flow an electric current in a glow plug 10 through an electromagnetic relay 6. After the time elapsed in the timer 1, the electric conduction, being stopped to the glow plug, causes its temperature to lower. The glow plug 10 produces thermoelectromotive force when it is not electrically conducted, then a decrease of temperature in the glow plug is detected by a detector circuit 2 with said electromotive force, causing a timer 3 to perform electric conduction to flow a current for a certain time in the glow plug through the electromagnetic relay 6. In this way, the temperature of the glow plug can be controlled to constant.
