摘要： PURPOSE:To cool an exhaust valve securely by injecting a fixed quantity of cooling water in the back side of a valve seat during the period when both suction and exhaut valves are closed in a four-cycle diesel engine, while an exhaust valve is closed in a two-cycle diesel engine. CONSTITUTION:A cooling water jetting nozzle 1 is set in the position inside an exhaust valve case 3 where the jetting and injection of cooling water in the back side of a valve seat 2 can be conducted. Water injection is conducted during the period when both suction and exhaust valves of four-cycle engine are closed and the exhaust valve of two-cycle engine is also closed. On the occasion, the quantity of water injected is set not to exceed the quantity which can be evaporated completely during the closure of the valves. Accordingly, the employment of such a means which is troublesome and liable to cause such an accident as water feeding to the movable part of the valves becomes unnecessary and because a direct cooling can be performed, the reliability of the device is increased to a large extent.

摘要： PURPOSE:To provide good controllability and make the construction simple by furnishing fuel passage which ensure fuel introduction both to two contacting points and the space between them, and thereby enabling injection of the fuel at extra-high pressure. CONSTITUTION:When valve is opened, the fuel oil passes through a valve seat 13 and is injected out of a nozzle 12 at the tip in atomized state. When the valve is closed, the tip of a spindle 20 and said valve seat 13 are contacting each other at the upper and lower edges 22, 23 of a recessed part 21. The fuel oil is however being introduced as far as into the space 14 upon passing through a passage for fuel introduction 24, and the lower edge 22 is provided so that the total contact surface pressure will not become excessive.

摘要： PURPOSE:To enhance the efficiency of cooling an exhaust valve, thereby reducing the required amount of air passed through a cylinder and enhance the efficiency of recovering heat from an exhaust gas, by a method wherein the closing timing of an exhaust valve is advanced and the valve is momentarily maintained at a low opening, in a Diesel engine. CONSTITUTION:The exhaust valve 21 is driven by an exhaust valve driving mechanism consisting of a rocker arm 23, a pushing rod 23, a roller 24 and a driving cam 25. In the case of a 4-stroke-cycle engine, the profile of the cam 25 is so set that closing of the exhaust valve 21 is started before the opening 2 of a suction vavle reaches 100% opening, and a low opening A is thereafter maintained at least until the bottom dead center is reached. The timing of 100% closing is appropriately set in accordance with the thermal efficiency of the engine and the valve-cooling effect after the valve 21 is maintained at the low opening A. Curve 1' represents the opening characteristic of a conventional exhaust valve.

摘要： PURPOSE:To reduce the exhaust effusion loss of an exhaust turbine combination engine, through a simple device, by providing variable turbine nozzles for the supercharger turbine and recovery turbine of the engine and regulating the degrees of opening of the nozzles to meet a prescribed condition. CONSTITUTION:Pressure sensors P-1-P-3, which detect the pressure in a cylinder, that upstream to a supercharger turbine 23 and that of intake, an intake temperature sensor T-1 and a crankshaft angle sensor U-1 are provided. A controller 32 governs regulators 33-36 on the basis of the detection signals from the sensors so that the pressure upstream to the supercharger turbine, that of intake, the point in time of closing of an intake valve and the temperature of the intake become prescribed values. The variable nozzles of the supercharger turbine 23 are controlled by the regulator 33, while the variable nozzles 31 of a recovery turbine 27 are controlled by the regulator 34. The point in time of closing of the intake valve not shown in the drawing is controlled by the regulator 35. An air cooler 25 is controlled by the regulator 36.

摘要： PURPOSE:To delay the fuel injection time in a fuel injection by nullifying the volume of the plunger stroke which results from the movement of the plunger in order to increase the pressure by shifting the piston in other device. CONSTITUTION:In the compression cycle of a fuel injection pump 1, a plunger 2 begins elevation, and the fuel between the head 3 of the plunger and a fuel passage 4 is compressed and the pressure increases. When the pressure of the fuel surpasses the force of the spring 7 in an adjusting device 5, the piston 6 begins to move rightward, and shifts by the volume of the stroke of the plunger 2 of the pump 1, and the compression of fuel is not developed during this time. When the piston 2 shifts untill it contacts with a stopper 8, and stops, the compression of fuel starts again, when the pressure reaches the valve opening pressure of a fuel valve 9, fuel injection starts. Thus, the time of fuel injection can be delayed by the time during which the piston 6 is moving.
