摘要： PROBLEM TO BE SOLVED: To provide a hybrid vehicle promoting warming up of an internal combustion engine and a control method of the hybrid vehicle. SOLUTION: The hybrid vehicle has an engine lubricating system 110, a motor lubricating system 120, and an engine oil pump 126 supplying a lubricating oil of the motor lubricating system 120 to an engine 22. When the lubricating oil temperature of the motor lubricating system 120 is higher than that of the engine lubricating system 110 reflecting temperature of the engine 22, the lubricating oil of the motor lubricating system 120 can be supplied to the engine 22 for promoting warming up of the engine 22. When operation of the engine 22 is stopped and travel is carried out by a motor, if the lubricating oil temperature of the engine lubricating system 110 is lower than a first temperature and the lubricating oil temperature of the motor lubricating system 120 is higher than a second temperature higher than the first temperature, control is carried out to drive the engine oil pump 126, so that warming up of the engine 22 can be promoted more surely.

摘要： PROBLEM TO BE SOLVED: To suppress the trouble involved in the change in compression ratio of an engine.
SOLUTION: At an increase in compression ratio (εi>ε(i-1)), an opening-increasing drive signal is outputted to a throttle valve driving actuator 63 (step S330) to forcedly increase the intake air quantity. In such a compression ratio-increasing state, the blow-by gas quantity to an intake pipe 50 is increased, and the air-fuel mixture carried into a combustion chamber is transited to fuel excessive side. However, since the intake air quantity is increased, such an excessive fuel is suppressed, and the disturbance of the fuel/air ratio carried to the combustion chamber after the increasing change of compression ratio is suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply system capable of simplifying a fuel return pipe while positively preventing vapor lock by constituting to prevent vapor discharged from a pump chamber, from being sucked again into the pump chamber from a fuel inlet.
SOLUTION: A vapor discharge passage 11 led out of the pump chamber 10b of a fuel pump 10 through a vapor jet 10a communicates with the upper part of a fuel tank 2. The vapor produced in the pump chamber 10b in the operation of the fuel pump is thereby pushed out to the vapor discharge passage 11 via the vapor jet 10a and discharged to the upper part of the fuel tank 2 distant from the fuel inlet 10c. Consequently, the vapor is not sucked again into the pump chamber 10b from the fuel inlet 10c, so that the occurrence of vapor lock in the pump chamber 10b can be suppressed to prevent a lowering of pump efficiency.

摘要： PROBLEM TO BE SOLVED: To provide a fuel supply device for liquified gas internal combustion engine capable of maintaining a fuel tank in a condition wherein fuel supply from the outside is possible. SOLUTION: In this fuel supply device, liquid phase fuel stored in the fuel tank 31 in a saturation state is force-fed by a fuel pump 32, the force-fed liquid phase fuel is injected and supplied to the internal combustion engine by a liquid phase fuel injector LIN, and the fuel in a delivery pipe 35 is circulated to the fuel tank 31 through a circulation passage Rd2. An oil feeding pressure, which is a pressure of the fuel pressurized and supplied from a fuel tank of an oil supply stand to the fuel tank 31 is calculated based on a saturation vapor characteristic of the fuel in the fuel tank 31 and an outside temperature. When the pressure of the fuel in the fuel tank 31 is equal to or more than the oil feeding pressure, gas phase fuel in the fuel tank 31 is supplied to the internal combustion engine by a gas phase fuel injector GIN.

摘要： PROBLEM TO BE SOLVED: To provide a liquefied gas fuel supply device for improving the filling performance of fuel by reducing a raised internal pressure of a fuel tank. SOLUTION: The fuel tank 2 is provided with a sub-fuel tank 15 communicated therewith through a communication pipe 17, and a manual valve 18 (communication valve) is mounted for opening and closing the communication pipe 17. When the internal pressure of the fuel tank 2 is higher than the predetermined pressure the manual valve 18 is opened when the internal pressure of the fuel tank 2 is reduced lower than the filling pressure, the valve 18 is closed to charge the fuel. As the valve 18 is opened or closed again after filling, the pressure in the fuel tank 2 can be reduced, and the filling performance of the fuel can be improved with a simple structure.

摘要： PROBLEM TO BE SOLVED: To improve the starting performance of an internal combustion engine by accurately regulating the amount of the injection fuel in an early stage in starting the internal combustion engine using liquefied gas as the fuel.
SOLUTION: The liquefied gas fuel is stored in the fuel supply piping between an upstream-side fuel cutoff valve and a downstream-side fuel cutoff valve in a state of pressurized fluid when an engine is stopped (S140-S170). Whereby bubbles are not generated in a storage part during the stop of the engine. Accordingly a time for compressing and liquefying the bubbles is omitted with respect to the fuel in the storage part, when the fuel is pressurized by a fuel pump in starting the engine, and the injectable fuel pressure is quickly applied to the liquefied fuel. Further, as the liquefied gas fuel in a state of the pressured liquid is supplied from the storage part to a delivery pipe side in starting, the regulation of the amount by the fuel injection valve is accurately performed from the early stage in starting, whereby the starting performance of the engine is improved.

摘要翻译：要解决的问题：通过使用液化气体作为燃料来启动内燃机的初期，通过精确地调节喷射燃料的量来提高内燃机的起动性能。解决方案：当发动机停止时，液化气体燃料在加压流体的状态下存储在上游侧燃料切断阀和下游侧燃料切断阀之间的燃料供给管路中（S140-S170）。在发动机停止期间，在存储部件中不产生气泡。因此，当起动发动机时燃料被燃料泵加压时，相对于储存部分中的燃料，省略了压缩和液化气泡的时间，并且可喷射的燃料压力迅速地施加到液化燃料。此外，由于在起动时将加压液体的液化气体燃料从储存部供给到输出管侧，因此从起动的早期准确地进行燃料喷射阀的量的调节，由此，发动机的起动性能得到提高。

摘要： PROBLEM TO BE SOLVED: To control the compression ratio of a variable compression ratio engine without using external driving force. SOLUTION: This variable compression ratio engine is provided with a support shaft holding means 6a integrally interlocked with a support shaft 53 for swingingly supporting a control rod 51 for specifying the locus of a bent part 430 of a connecting rod 43, to hold the support shaft 53 so as to be displaceable toward the connecting rod 43 side and in the reverse direction, and a free motion limiting means 6b allowing the free motion of the support shaft 53 by the acting force received by the support shaft 53 from the control rod 51 when the acting force is in the same direction as the command displacement direction of the support shaft 53 set on the basis of a command compression ratio while putting the support shaft in a stop state when the acting force is in the reverse direction to the command displacement direction. The acting force alternately changed in direction by the explosive force of a mixture applied to a piston 41 is thereby used as driving force for displacing the support shaft 53 in the command displacement direction.

摘要： PURPOSE:To correctly determine a time when charging of a battery is necessary, by preliminarily setting a current required at an average accelerating time and calculating a voltage of the battery when the set current is discharged from a discharging current from the battery and a voltage of the battery. CONSTITUTION:After a current and a voltage are detected, it is detected whether charging has started from a code of the detected current. Once the charging has started, a process to release charging/polarization is carried out. The flow of the detecting operation is refrained from proceeding until the charging/polarization is released. The detected current is temporarily stored as a change of a capacity. It is detected whether the stored capacity change exceeds a rated capacity. Then, voltage of a battery when the current is discharged which is necessary at an average accelerating time is calculated from a pair of the measured current value and voltage value and stored. Whether a stored count of true battery voltages has reached a regulated value or more is compared, thereby to calculate a true voltage of the battery. The battery voltage of the highest frequency is estimated to be a true value when a predetermined current is discharged. A time when the battery is to be charged, is determined based on the estimated voltage value.
