摘要： PROBLEM TO BE SOLVED: To improve low temperature startability in a cylinder injection type engine when alcohol fuel (100% alcohol or mixed fuel containing alcohol).
SOLUTION: When alcohol concentration of the fuel is not less than prescribed concentration and cooling water temperature is not higher than prescribed temperature, it is judged that injected fuel is not easily gasified, start target fuel pressure is set to an appropriate value according to alcohol concentration of fuel and cooling water temperature, and fuel injection of a fuel injection valve 21 is started after raising actual fuel pressure to pressure close to the start target fuel pressure by a high pressure pump 31 in start of the engine 11. Although high pressure fuel is directly injected into a cylinder by the fuel injection valve 21 after fuel injection start, time from fuel injection to start of combustion is shortened to start combustion and accelerate gasification of injected fuel before much injected fuel adheres on a cylinder inside wall surface, a piston and the like by executing compression stroke injection in which fuel is injected in compression stroke during engine start or a prescribed period after engine start.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for treating vaporized fuel in an internal combustion engine, wherein the apparatus can more accurately control the flow rate of the mixture to be introduced into an intake pipe.
SOLUTION: In the apparatus for treating vaporized fuel, the vaporized fuel in a fuel tank is temporarily adsorbed into adsorption material stored in a canister, and the vaporized fuel adsorbed in the adsorption material is discharged into the intake pipe of the internal combustion engine when the internal combustion engine is operating. In this case, air is flowed through a specified throttle by operating a pump, and the pressure difference ΔP0 between the portions before and after the throttle is detected (S202). Next, the air-fuel mixture including the vaporized fuel is discharged from the canister through a fuel tank, the canister, and the throttle, and the pressure difference ΔP1 between the portions before and after the throttle is detected (S205). Then, the ratio P of the pressure difference and also the concentration C of the vaporized fuel to be used in the flow rate control are calculated from the ratio P of the pressure difference (S209, S210). When the sloshing of the fuel has occurred during detecting the pressure difference ΔP1, the accuracy of the pressure difference ΔP1 may be lowered. Therefore, the ratio P of the pressure difference is not calculated, and a routine is finished.

摘要： PROBLEM TO BE SOLVED: To improve responsiveness of resume (RESUME) control at the time of C/C (cruise control) of a vehicle.
SOLUTION: In the resume control at the time of C/C, increase rate CRSRED of a target vehicle speed is changed in accordance with deviation between a resume stored vehicle speed SRSETM and a target vehicle speed SRSET. When a RESUME switch press flag XRREM is ON and a SET command reception completion flag XRACT is ON, the larger deviation between the resume stored vehicle speed SRSETM and current vehicle speed SWDWS (equal to the target vehicle speed SRSET) becomes, the larger the increase rate CRSRED of the target vehicle speed is added to the target vehicle speed SRSET. As a result, by the resume control at the time of C/C, the target vehicle speed SRSET can be rapidly converged on the resume stored vehicle speed SRSETM.

摘要： PROBLEM TO BE SOLVED: To certainly determine the trouble of an instrument itself in a measuring instrument for a liquid concentration. SOLUTION: The microcomputer of an alcohol concentration sensor reads the measured value S(f1) corresponding to frequency f1 (S100) and further reads a measured value S(f2) corresponding to frequency f2 (S110), then calculates the difference ¾S(f1)-S(f2)¾ between two measured values (S120). When the difference ¾S(f1)-S(f2)¾ between two measured values is a predetermined value Th or below continues (S130:YES, S140:YES), the microcomputer of the alcohol concentration sensor determines stack abnormality to output a PWM signal of specific frequency different from that of normal time to an engine ECU 300 (S170).

摘要： PROBLEM TO BE SOLVED: To prevent catalyst melting when an actual injection amount is limited by a maximum injection amount injectable by a normal fuel injection valve in execution of fail safe control of increasing an injection amount of the normal fuel injection valve if there is abnormality in any of the fuel injection valves in regard to an internal combustion engine respectively provided with two fuel injection valves in an intake side of each cylinder. SOLUTION: When either one of the two injection valves 21 of each cylinder becomes abnormal, and when the actual injection amount is limited by the maximum injection amount injectable by the normal fuel injection valve 21 in execution of the fail safe control increasing the injection amount of the normal fuel injection valve 21, by limiting a duty of an actuator of an intake air volume adjusting mechanism (for example, a throttle opening or the like), an intake air volume is limited to an intake air volume not causing catalyst melting. By this, enlargement of deviation to a lean side of an air-fuel ratio can be prevented, and the catalyst melting can be prevented. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device for an internal combustion engine capable of making purge quantity sufficiently large. SOLUTION: This device is provided with a first fuel condition determination means determining fuel concentration purged from a canister based on slippage quantity of actually measured air fuel ratio from target air fuel ratio, a second fuel condition determination means determining fuel concentration under a condition where a purge control valve is open, an abnormality detection means detecting abnormality of the second fuel condition determination means, and an air fuel ratio control means controlling fuel injection quantity based on fuel concentration. If the abnormality detection means does not detect abnormality, the air fuel ratio control means uses fuel concentration determined by the second fuel condition determination means at a time of purge start or re-start, and uses fuel concentration determined by the first fuel condition determination means during purging. Consequently, purge ratio can be kept large from the time of purge start or re-start. However, fuel concentration determined by the first fuel condition determination means is always used during abnormality diagnosis by the second fuel condition determination means.

摘要： PROBLEM TO BE SOLVED: To prevent the disordering of an air/fuel ratio caused by the air sucked to an intake pipe from a brake booster in starting.
SOLUTION: A bypass passage 36 bypassing a check valve 35 is connected with a negative pressure introduction passage 23 of a brake booster 24, and a switch valve 37 is mounted on the bypass passage 36. The switch valve 37 is temporarily opened just before the start of the engine 11 to open the bypass passage 36, whereby the remaining pressure in the brake booster 24 is adjusted to be approximately equal to the atmospheric pressure (pressure same as that in the intake pipe 12). Whereby the pressure in the brake booster 24 in starting can be made approximately same as the atmospheric pressure every time, and the amount of air flowing into the intake pipe 12 from the brake booster 24 can be made approximately constant in starting. The fuel injection amount can be determined while considering the amount of air, without detecting the amount of air sucked into the intake pipe 12 from the brake booster 24 in starting.

摘要： PROBLEM TO BE SOLVED: To secure the control accuracy of fuel injection control reflecting an alcohol concentration of fuel even if vapor is generated in the fuel, and the detection accuracy of an alcohol concentration sensor is deteriorated. SOLUTION: When a fuel temperature detected by a fuel temperature sensor 31 is not higher than a prescribed limit temperature, it is determined that the detection accuracy of the alcohol concentration sensor 36 is high since vapor is not generated in the fuel, fuel injection control is executed by using a current alcohol concentration detection value of the fuel accurately detected by the alcohol concentration sensor 36, and the alcohol concentration detection value is stored in a rewritable nonvolatile memory such as a backup RAM of an ECU 37. When the fuel temperature is higher than the limit temperature, it is determined that the detection accuracy of the alcohol concentration sensor 36 may be deteriorated since vapor may be generated in the fuel, fuel injection control is executed by using the alcohol concentration stored value of the fuel stored in the backup RAM of the ECU 37 or the like.
