摘要： An ECU (13) includes: throttle-valve opening-degree control means (131) for controlling an intake airflow rate; target output-torque calculating means (132) for calculating a target output torque from an operating state of an engine (1) and an operation of an accelerator performed by a driver; target ignition-timing calculating means (133) for calculating target ignition timing based on the operating state of the engine (1); actual output-torque calculating means (134) for calculating an actual output torque of the engine (1) based on an engine rpm, a charging efficiency, the target ignition timing, an air-fuel ratio, and a total heating value of a fuel; and target intake-air quantity calculating means (135) for calculating a charging efficiency-to-torque conversion factor based on the charging efficiency and the actual output torque, and calculating a target charging efficiency based on the target output torque and the charging efficiency-to-torque conversion factor to calculate a target intake air quantity based on the target charging efficiency. Torque control for the engine is performed while the fuel properties are loaded as information, and hence an engine control amount for realizing the target output torque is realized with high accuracy.

摘要： A circumferential flow type liquid pump includes an impeller with vanes on its outer periphery, and a pump casing assembly defining an arcuate elongated pump flow path along the outer periphery of the impeller and a suction inlet and a discharge outlet at both ends of the pump flow path. The pump casing assembly includes a radially-extending gas venting path which is opened in the inner periphery of the pump flow path near the impeller and separated by a step from the bottom of the pump flow path, and a through-hole much larger in sectional area than the gas venting path, through which the gas venting path is communicated with the outside of the pump casing assembly. Bubbles formed by vaporization of the fuel in the pump flow path are positively discharged from the pump casing assembly, and no vapor locking is caused.

摘要： A circumferential flow type fuel pump has a circumferential fuel flow passage provided around an impeller and a gas discharging hole formed in the inner wall of the fuel flow passage in such a manner that the fuel flow passage is communicated with the outside of the fuel pump. The upstream and portion of the fuel flow passage extends to a position near the gas discharging hole and is formed into a flow passage enlarging part by increasing its sectional area radially outwardly, whereby the pumping capacity is substantially maintained unchanged even under severe operation conditions such as at a high fuel temperature.
