Abstract: PROBLEM TO BE SOLVED: To improve environmental performance of an oil filter by easily disposing used elements while stably securing the form and performance of the filter paper of the filter element in use in a filter whose housing containing an cylindrical element is divided into two parts in the vertical direction for replacing only the element. SOLUTION: This oil filter oil-tightly holds the upper and lower end sections of an element 2 by externally fitting the upper end section of the element 2 to the boss section 11 of a housing body 3, jointing a seal member 31 to a protector plate 13, fittingly holding the lower end to a collar 30 through a seal member 32 and pressingly energizing the lower end upward by a coil spring 29. The flow of engine oil is prevented from directly abutting on the end of the element 2 by enlarging the diameter of the protector plate 13 more than that of the element 2. The protector plate 13 is arranged in the housing body 3, and the seal members 31 and 32 are made of felt that is safely incineratable soft material.

Abstract: PURPOSE:To stabilize combustion state by operating a fuel injection valve at an intake port equipped with a shutter valve between two intake ports which are independent each other, in delay by a prescribed time from the opening timing of the shutter valve. CONSTITUTION:As for a rotary piston engine equipped with a primary turbosupercharger 4 and a secondary turbosupercharger 6, an ECU 46 judges if the engine operation state at present is in a high load region where both the superchargers 4 and 6 are driven, and when the result is 'YES' and the control by both the superchargers 4 and 6 is carried out, it is judged if an exhaust cut valve 23 is opened, and the counting-up of a fuel injection delaying timer is completed or not. When the counting-up is completed, a fuel injection valve 20 at an intake port 18 on the secondary supercharger 6 side is driven to carry out fuel injection. Accordingly, fuel is blasted after the flow speed of the intake is sufficiently increased by the prerevolution, and the mixing of fuel and intake is improved, and the combustion performance is improved.

Abstract: PURPOSE:To perform reliable closing of a waist gate during low load running by a method wherein capacity of a pressure actuator with which an exhaust gas relief means is formed is set to a value higher than that of a pressure actuator with which an exhaust gas leakage means is formed. CONSTITUTION:A control device is provided with primary and secondary exhaust turbosuperchargers 204 and 206, and when an engine 201 in a high load state, the secondary turbosupercharger 206 is actuated. In which case, capacity of an actuator 231 to operate an exhaust gas leakage valve 230 to control an supercharging pressure in a low load state is differed from that of an actuator 226 to actuate a waist gate 227 to control a supercharging pressure in a high load state, and capacity of the actuator 226 for the waist gate valve is set to a relatively high value. This constitution performs reliable closing of the actuator 226 for the waist gate during low load running, ensures enough opening and closing response to the exhaust gas leakage valve, and improves running properties.
